• The Hire popularized the use of short films as a form of advertising, as the success of that series proved that short films were just as valid and effective an advertising method as broadcast television commercials, not to mention that they can bring major artistic merit to a brand. Since then, a number of high-profile and luxury brands have funded and produced short films every year for this purpose.

• A.I.: Artificial Intelligence didn't invent alternate reality games, but its game The Beast popularized many elements of the modern ARG, such as kayfabe, metapuzzles, transmedia gameplay, and live-action role-playing.

• AKIRA was the Trope Codifier for anime as a whole in the U.S. and U.K. — a "cartoon" that was dark, grim, violent, bloody, beautiful and not a little mind screwy. As a consequence, it burrowed into the collective subconscious and created a new image that took years more to shake off.
• Azumanga Daioh is the eternal Trope Codifier of the Schoolgirl Series and associated tropes, including Wacky Homeroom and Sensei-chan.
• While Black Lagoon introduced the Cluster F-Bomb and Sir Swears-a-Lot tropes in anime, Panty & Stocking with Garterbelt has the most swearing out of any anime.
• Most of the general formula for "standard" non-action Shoujo works can be traced back to Boys Over Flowers. The visual design and personality of the Stock Shoujo Heroine, the manly, aggressive love interest, the themes of inter-class romance, and the rampant Melodrama weren't invented by Tsukushi and Tsukasa, but they were all present simultaneously, as the main focal points in a work that got extremely popular and influential.
• Crows and its sequel series Worst have their hands in just about every delinquency manga made after it. Its mixture of down to earth troubles, more nuanced observation of delinquent culture, and the more realistic art reflect in many series down the line.
• While there had been examples and uses of Cyberpunk tropes in other series such as Appleseed, Ghost in the Shell is seen as codifying Cyberpunk themes into anime such as cyborgs, The Metaverse, and other such themes.
• If Fist of the North Star is the Trope Maker for the shonen Fighting Series, then Dragon Ball and Dragon Ball Z are the codifiers. Dragon Ball's very own Goku also codified the Stock Shōnen Hero.
  • Speaking of Fist of the North Star, it can be considered the codifier for the You Are Already Dead and Rapid-Fire Fisticuffs tropes, at least for anime and manga, given that a good many examples of both tropes are either homages to, or parodies of, the series.
• Fullmetal Alchemist popularized the concept of Equivalent Exchange and "Magic A" Is "Magic A", at least for anime and manga.
• Yuno Gasai from Future Diary is essentially the codifier for the Yandere trope. While she had predecessors for this trope before her introduction (such as Yukako below), her character practically defined the trope in its current form, becoming both types throughout the story.
• JoJo's Bizarre Adventure is the main reason Japanese manga et al. has Guardian Entities.
  • It also codified katakana Written Sound Effects for the English-speaking portion of the fanbase, to the point where they're often done in western media to specifically call back to JoJo's as opposed to any other series.
  • Diamond is Unbreakable in particular codified the Yandere trope. Yukako Yamagishi, a girl who has a dangerously obessive love for Koichi, first appeared in 1992, long before the trope took off in popularity.
• Love Hina essentially defined the turn-of-the-millennium style of Unwanted Harems.
• While it certainly existed earlier, Magical Girl Lyrical Nanoha codified the Dark Magical Girl trope for anime with the character of Fate Testarossa.
• Mobile Suit Gundam Wing jump-started the trend of Humongous Mecha series having Bishōnen protagonists to give it a Periphery Demographic of young females.
• Neon Genesis Evangelion is the Trope Codifier for Darker and Edgier, Deconstructed mecha anime with a metaphysical edge. GaoGaiGar and Tengen Toppa Gurren Lagann attempted to Reconstruct the genre after it became overtaken by Eva-inspired works.
  • Evangelion completely redefined the whole medium of TV anime and what it could do. Before Evangelion the vast majority of TV anime was either adaptations of popular manga or family-friendly programs, but the show paved the way for several Anime First franchises which explored darker and more mature themes, material that before had been largely relegated to direct-to-video productions (the so-called OVAs) and therefore only reached a niche market.
• While examples of the Whip Sword long predate it (the Indian urumi, a sword with a long and flexible blade, for instance has downright ancient roots) the standard "sword that can split into segments linked by a wire" design that most people think of was created and popularized by Panzer World Galient. In fact, in Japan, it's the Trope Namer: swords of this kind are near-universally referred to as "Galient Swords", sometimes even directly named as such in other media unrelated to the show.
• Pokémon the Series: Every time Team Rocket is "blasting off again" is the Trope Codifier for A Twinkle in the Sky.
• While mostly unknown in English speaking countries until The Prince of Tennis, the sports anime genre has been a staple for over half a century now. Having so many subgenres and approaches, the scene has multiple codifiers.
  • In The '60s, Kyojin no Hoshi started the supokon (sports and guts) genre, putting the focus on the grueling training and sacrifice in the dogged pursuit of the top. It is the closest thing to a codifier for all sports anime and manga, and especially baseball. Tiger Mask and Tomorrow's Joe similarly codified wrestling and boxing series, respectively. All of them were written by Ikki Kajiwara, which makes him singlehandedly responsible for starting the genre.
  • Attack No. 1 codified Shoujo sports series as well as volleyball manga with hot-blooded grace, with Aim for the Ace! doing the same for tennis during The '70s.
  • The '80s saw the arrival of one of the most popular sports manga and anime, Captain Tsubasa. While occasionally violent for drama, it was a much more bright-eyed, rip-roaring take on the genre. Physics-defying trick shots had appeared in other series long before, mostly in baseball series. But Tsubasa might be the most remembered for its bombastic use of them by an entire team. It codified soccer series as well as keeping more of the focus on the sheer fun of the game.
    • Pro Golfer Saru began as a manga in the '70s but it was its '80s anime adaptation that came to real prominence. Featuring a young protagonist and very unorthodox, over the top golfing techniques to distinguish every swing while skipping the boring parts, it codified golfing series, at least on the shounen side of things.
  • In The '90s, Slam Dunk became extremely popular despite keeping everything down to earth. So popular that it became the single best selling sports manga of all time, played a large part in upholding the golden age of Shonen Jump, and made the real life sport of basketball bigger in Asia. Rather than being about larger than life, superhuman geniuses, it balanced daily life, comedy, and relationships. The series codified basketball manga and how to realistically approach a sports series while keeping audiences hooked.
• Puella Magi Madoka Magica wasn't the first series to deconstruct the Magical Girl genre (as older series like Revolutionary Girl Utena and Phantom Thief Jeanne also examined its associated tropes from darker and more serious angles), but it was still the anime that made the Magical Girl Genre Deconstruction suddenly fill the market compared to the more traditional takes on the genre. It plays with just about every cliche magical girl trope and shows just how making young girls fight violent monsters can really mess up their lives.
• Ranma ½'s Ranma Saotome and Akane Tendo aren't even Rumiko Takahashi's first couple with Belligerent Sexual Tension. But they're the standard by which all others are measured.
  • Ranma is also the most likely codifier for Martial Arts and Crafts unless someone who knows their kung-fu flicks can dethrone it — it's probably harder to think of a pursuit they didn't use in the series than one they did.
  • Ryoga Hibiki is the codifier for No Sense of Direction. His sense of direction is so bad that he literally traverses across continents and oceans without even realizing it.
  • Ranma Saotome himself is very likely the main Trope Codifier for the Gender Bender trope (or at least its Sex Shifter variation) in modern fiction. His transformation is due to an accident (earlier instances often had no explanation at all), he changes sexes due to specific stimuli (previously, transformation was most often only one way, and if there was ever a way of changing back and forth, it was something that could never be controlled from the outside), and he keeps his original personality at any time (before him, previous instances of the trope sometimes changed personality when transforming). While later instances don't necessarily share all of these elements, they are the standards by which those instances are considered, to the point the Gender Bender has been seen as a Characteristic Trope for the work, at least in the anime fandom.
• In Rurouni Kenshin, the titular character is the codifier for "X" Marks the Hero.
• Sailor Moon is frequently cited as the first user of the Magical Girl Warrior subset of Magical Girl shows by adding Sentai tropes to the genre. Cutey Honey used some of the tropes, but was usually seen as a straight-up Super Hero, especially since at the time "Magical Girl" meant Cute Witch. In Japan, if it's not the Sailor Senshi, you can bet it's going to be the Pretty Cure franchise instead. The other (or other other) codifier for the Magical Girl genre in general is widely considered to be Cardcaptor Sakura.
  • Design-wise, Luna and Artemis were the first to popularize magical girl mascots as Ridiculously Cute Critters with big sparkly anime eyes. Magical girl mascots from the Pierrot and Ashi Productions magical girls and the earlier Toei majokko were drawn in a more cartoony style and were frequently some flavor of Ugly Cute. Luna and Artemis's more conventionally cute anime designs majorly influenced not only future magical girl series, but anime mascot characters in general.
• Chibi-Neko from The Star of Cottonland is one of the earliest known Cat Girls in manga and anime (as the manga was first published in 1978), and the manga is widely considered to be responsible for spreading the popularity of cat girls to other series.
• Speaking of Tengen Toppa Gurren Lagann, while the Getter Robo series introduced the This Is a Drill trope to mecha fans, a lot of them will remember the former for taking said trope as a massive plot point.
• Yuuki Rito of To Love Ru was certainly not the first harem series protagonist to have a Suggestive Collision or Thanks for the Mammary moment, but he does it so often and to such a ridiculous degree that any other character with similar issues will be inevitably be compared to him.
• Queen Oyuki from Urusei Yatsura is frequently cited as the main reason why Yuki-onna are often presented as royalty, or at least wearing crowns.
• Yu-Gi-Oh! is the reason we have Anime Hair. Its second anime adaptation, Yu-Gi-Oh! Duel Monsters, codified the card game battle genre.

• Sandro Botticelli's The Birth of Venus, while not the creator of the Hand-or-Object Underwear trope, was one of the first to come out of the Early Renaissance and has been emulated ever since, directly inspired from the various Capitoline Venus ("Modest Venus") statues from Ancient Rome.
• Many paintings featuring the Reclining Venus pose from The Renaissance onward credit the Dresden Venus as their direct inspiration. It's credited as being the artwork that made this into a Stock Pose, inspiring copycats from Girolamo da Treviso to Titian, Valesquez, Diego Velazquez, and Cabanel. It is the first known reclining nude in Western painting, and together with the Pastoral Concert (Louvre), another painting disputed between Giorgione and Titian, it established "the genre of erotic mythological pastoral", with female nudes in a landscape, accompanied in that case by clothed males. A single nude woman in any position was an unusual subject for a large painting at the time, although it was to become popular for centuries afterward, as "the reclining female nude" became a distinctive feature of Venetian painting.
• The Scream codified several of the Expressionist movement's characteristics. Mainly, the exaggerated Color Contrasts and the aggressive brush strokes that prioritize conveying emotion over technique.
• The Swing marked the tonal shift from intense, religious artworks commonly associated with the early Baroque to Lighter and Softer depictions of the aristocratic life of the Rococo.

• The mainline Archie Comics in the Archie franchise is both the Trope Codifier for the titular Betty and Veronica and the Love Triangle in American popular culture, with the romantic entanglement between Betty Cooper and Veronica Lodge over the titular Archie Andrews having been a fixture of American comics since 1941 and spreading into multiple media adapations.
• Superheroes, being another tentpole of the medium (especially for American comics), has several such examples, to the point they could have their own page. More specifically:
  • Superman is the Trope Codifier of superheroes in general, and also for the Flying Brick kind of superhero, as well as the idea of a superhero as The Cape.
  • Lex Luthor is the Trope Codifier of supervillains in general.
  • Watchmen and Batman: The Dark Knight Returns are co-codifiers of Darker and Edgier.
  • Batman himself is the Trope Codifier of the Badass Normal superheroes and The Cowl.
  • The Joker is the Trope Codifier for Monster Clowns. (It was Pennywise from Stephen King's It who truly took the trope mainstream, though.) He is also the Codifier of the Arch-Enemy, as his relationship with Batman has practically become shorthand for describing any particular character's greatest and most personal foe.
  • Captain America is easily the Trope Codifier for Captain Patriotic, being one of the earliest and most prolific examples of the trope. He is also the Trope Codifier for Captain Geographic.
  • Catwoman was the first really popular female anti-hero.
  • Daredevil is widely considered the most prolific example of the Disability Superpower. Charles Xavier would otherwise be this, but he's more of an Ur-Example.
  • Spider-Man is often credited as being the Trope Codifier for both the non-sidekick Kid Hero and Wake Up, Go to School, Save the World. Also to Building Swing, since almost every time you see it anywhere else, it is a direct reference to Spidey or lampshaded by a character.
  • The Flash is the Trope Codifier for the Super-Speed hero.
  • Robin is the codifier for Kid Sidekick.
  • The Punisher is the Trope Codifier of the Sociopathic Hero. He was, by far, the most popular costumed "superhero" to kill his enemies rather than putting them to jail. And he'd been doing it long before the Dark Age of Comics.
  • The Incredible Hulk is the Trope Codifier for the Jekyll & Hyde Superhero. He is also the Trope Codifier for the Unstoppable Rage Superhero and the Hulking Out Superhero.
  • Iron Man is commonly recognized as the definitive Powered Armor superhero.
  • The Mighty Thor is one of the earliest and most iconic examples of the Superhero Gods trope.
  • John Constantine of Hellblazer is the Trope Codifier of characters being Exiled from Continuity and Did You Just Scam Cthulhu?.
  • Although he wasn't the first, Deadpool by far is the most well-known character who breaks the fourth wall. Virtually every media about him from comics to memes lack the aforementioned wall (and he knows it).
  • Wonder Woman is the Codifier for female superheroes, as well as the first major superhero whose origin and universe are based on ancient myths.
  • Supergirl is the Trope Codifier of Distaff Counterpart characters, having all of Superman's powers.
  • Crisis on Infinite Earths is the Codifier for the Crisis Crossover, inventing many of the tropes associated with these types of events.
  • If Namor the Sub-Mariner was the Trope Maker, then Arthur Curry, a.k.a. Aquaman is the Trope Codifier. Being the half-Atlantean son of Queen Atlanna, he would eventually become King of Atlantis and use his extraordinary powers to protect both Human Subspecies from anything that would threaten them, becoming a member of the Justice League of America. He's so popular, most (though not all) examples of this trope were deliberately made to be Stock Parodies of Aquaman, for better or for worse.
  • The concept of a hulking swamp humanoid made up muck, plants, and fungus and possibly formed from the reanimated corpse of a person begins with Theodore Sturgeon's short story "It (1940)", which introduced the basic concept, and went through The Heap, which moved it from a forest to a swamp and ported it into comic books, but its more recongizable form was popularized and codified by Marvel's Man-Thing and DC's Swamp Thing. Hulking swamp-based humanoid and optionally reanimated Muck Monsters appeared numerous times in later pulp fiction, comic books, and horror, but most are based directly or indirectly on the two Things.

• The Far Side was far from being the first single-panel comic strip, but it made the format popular again in the 1980s.
• While the joke existed for as long as weekends did, Garfield is the codifier for Hating on Monday, with most straight examples of the trope being references to the comic.

• Whether My Immortal is actually a Troll Fic is up for debate, but the work has undoubtedly influenced several intentionally bad fanfics. Protagonists with hilariously bad names, hyperfocus on fashion and music genres, over-the-top Wangst, and heaping doses of Rouge Angles of Satin have all become common features.

• Sleeping Beauty (1959) codified what many consider the "Disney Princess formula" of the Disney Animated Canon and its many imitators, especially the films of The Renaissance Age of Animation, particularly regarding its characters like Aurora for Princess Classic and Rebellious Princess, Phillip for Prince Charming and Knight in Shining Armor, the Three Fairies for Fairy Companion and Spotlight-Stealing Squad, Maleficent for Card-Carrying Villain and One-Winged Angel, and Samson for Cool Horse and Non-Human Sidekick.

• 28 Days Later popularized and codified the Technically Living Zombie archetype with the Rage Infected, who were highly aggressive berserkers that ran and attacked any uninfected person. Although classic zombie apocalypse works like I Am Legend did feature technically living zombies that were both fast and diseased, such zombies were usually sapient and thus demonstrated more obviously human behavior, a far cry from the Rage Infected's animalistic fury.
• While far from the first evil A.I. in sci-fi, Hal 9000 from 2001: A Space Odyssey established a lot of the tropes and motifs around computers turning rogue, with most instances of A.I. Is a Crapshoot taking at least some inspiration from it even today.
• Alien codified the biomechanical look and the weird alien biology. The sequel, Aliens, popularized a certain type of "space marine" and bug alien-like life.
• Surprisingly, despite being a parody about parodies of the James Bond franchise, Austin Powers is the first thing many think of when a "parody of '70s spy movies" is mentioned. The phenomenon is such that Ernst Stavro Blofeld, the character that Dr. Evil is parodying, ended up being overshadowed by the parody itself.
• For the use of Time Travel in media, the Ur-Example is hard to identify and the Trope Maker is The Time Machine by H. G. Wells. The Trope Codifier is Back to the Future (1985).
• Batman (1989) was not the first Superhero movie, but it was the one that showed that superheroes were very profitable. It also altered the archetype of the Summer Blockbuster from "huge mass-marketing machines that were as much made to sell merchandise as they were to sell tickets" to "huge mass-marketing machines that were as much made to sell merchandise as they were to sell tickets, and are based on an existing property that the audience already has an attachment to".
• For Pie in the Face, the massive pie fight in the Laurel and Hardy silent short The Battle of the Century.
• The Birth of a Nation pulled together all of the little camera tricks and editing techniques that were tried in the early years of film into a coherent set of storytelling tools, making it one of the most important movies in the history of film. It was also horrendously racist. The gymnastics film history classes have to go through because of this are quite amusing.
  • The film caused such a headache for critic Roger Ebert when he repeatedly considered featuring it in his Great Movies series of essays that he always held off writing about it. When he finally decided to address it, he did it in two parts, explaining to readers that Part 1 would discuss the racism and history, just to get it out of the way. Part 2 would then be free to discuss the art of filmmaking without offending anyone. Even with the boundaries clearly defined, he had a heck of time writing that essay.
• Black Hawk Down is the first major movie that semi-accurately and dramatically depicted modern, 21st century (although the movie actually takes place in 90s, the principle is intact) warfare. Portrayal of urban warfare in almost virtually every single form of visual media that came after either directly or indirectly gets aesthetic inspiration from this movie, particularly video games such as Modern Warfare, Metal Gear Solid 4: Guns of the Patriots, and Resident Evil 5.
• Blade Runner is the codifier of Cyberpunk. It was one of the first films that portrayed the future as more dark and grimy and served as the inspiration for a lot of films.
• The Blair Witch Project
  • The film codified the found footage horror films of the 2000s and beyond, showing how a movie with a cheap budget can still scare the audience.
  • While Viral Marketing wasn't new in 1999, The Blair Witch Project was one of the earliest works to use the Internet as a marketing tool.
• Blind Chance codified the Split Timelines Plot. The Trope Maker is "Roads of Destiny".
• Blood and Black Lace codified the giallo's trademark tropes: colorful cinematography, graphic violence, and beautiful victims. Mario Bava's other giallo movie The Girl Who Knew Too Much (1963) is the Trope Maker, but it was relatively bloodless and was in black and white.
• The Bourne Series became this for modern, realistically presented action thrillers, particularly through its heavy use of documentary-style Jitter Cam, liberal use of Le Parkour, and brutally-efficient fight scenes, as well as giving a new shot of adrenaline to the One-Man Army trope. While the likes of Michael Mann and Luc Besson had made films in this style before, the success of the Bourne franchise saw it explode in the mid-2000s.
• Breakfast at Tiffany's: The Little Black Dress is thought to have originated during the 1920s, but Audrey Hepburn as Holly Golightly in the 1960 adaptation is generally thought to be the Trope Codifier.
• There were car chases on film before, but the one in Bullitt became the most famous one which all films after tried to emulate.
• The Carry On... Series codified Affectionate Parody because of their movies based on other films and genres; it also broke barriers between claims of copyright from Hollywood, who threatened to sue them, eventually losing their case in court.^note This is probably the reason why parody is filed under Fair Use. However, the movies were the Trope Maker of Awful British Sex Comedy (the codifiers were Confessions of a... series) due to the use of explicit nudity in a time when British media was against it. Ironically, when the Carry On franchise did a parody full of blatant Fanservice, it was called one of the worst in the series.
• The Creature from the Black Lagoon wasn't the first Fish Person, but he's certainly the best-known and most influential example.
• The 1931 movie version of Dracula codified most modern Vampire Tropes.
  • And the Trope Codifier for Our Vampires Are Different would be Nosferatu, which was where vampires being weak to sunlight originated from.
• Drunken Master: Although Drunken Boxing is a real Chinese martial art that appears in fiction as old as the 14th-century novel Water Margin, most modern works tend to reference Jackie Chan's comedic take on the form. By extension, it also codified the Drunken Master trope.
• When you think on a voyage to the inside of the human body, you are basically thinking on Fantastic Voyage.
• David Cronenberg's The Fly (1986) codified two tropes — one of which came to define an actor's career.
  • Most any sci-fi/horror film — or media beyond literature, in fact — that involves a Slow Transformation of a human into something else takes off from how memorably and powerfully the trope was used in this film, especially in an era when Transformation Is a Free Action was more common.
  • The Doomed Protagonist Seth Brundle was not the first Gibbering Genius on film, or even the first one Jeff Goldblum played (that would be the developer of an artificial heart in 1981's Threshold). But it ended up being Goldblum's Star-Making Role, and made him the go-to actor for similar characters — most obviously Dr. Ian Malcolm in the Jurassic Park franchise — and Motor Mouths in general for decades to come.
• The mad scientist's hunchbacked lab assistant originates with Frankenstein (1931) and its stage predecessors. But the boilerplate Igor — bugeyed, dressed in hooded Medieval clothing, and named "Igor" — was codified by Mel Brooks' parody Young Frankenstein. (His name was borrowed from Son of Frankenstein, but Ygor there is a villain in his own right and not merely Frankenstein's sidekick.) It's probably telling that just about every Igor who fits the pattern of how an Igor is allegedly supposed to look, talk and behave is a parody.
• Although not the first in the slasher genre, the Halloween and Friday the 13th franchises codified the genre's more famous tropes.
  • Halloween (1978):
    • Masked slasher antagonists were nothing new by the time of Michael Myers's debut (see The Texas Chain Saw Massacre (1974) or the older giallo film Blood and Black Lace), but Michael's theft of a mask from a store popularized the concept. It also helps that the movie takes place on Halloween, a holiday associated with horror and costumes.
    • Plenty of later slasher villains would imitate Michael's ambiguously supernatural teleportation.
    • Laurie Strode characterized the innocent nature of the Final Girl. Unlike her extroverted friends Annie and Lynda, Laurie doesn't have a boyfriend and lacks experience in smoking pot.
  • Friday the 13th (1980): The villain's Motive Rant about irresponsible, horny counselors made the Sex Signals Death trope more obvious.
  • Friday the 13th Part 2: In his first appearance as the killer, Jason wore a sack over his face, codifying the Sackhead Slasher archetype.
• Godzilla is the most well-known Kaiju and basically created the tokusatsu, together with King Kong, both are the most well known giant monsters. Even though, The Beast from 20,000 Fathoms set the standard for atomic monsters from their time.
• Typically, mafia films borrow from one of two cookie sheets: GoodFellas (for black comedies) or The Godfather (operatic tragedies).
  The Agony Booth: Brando gives his best performance, a legendary bit of acting that's been imitated so often by so many people that calling it clichéd is, in itself, a cliché! You realize how odd that is? Jesus, a thing like that should rupture the flow of time and send reality as we know it into a tailspin. I'm not sure what's kept this from happening, but I'm fairly sure it's connected to the Cubs not making it to the World Series. Sorry Chicago, but I think the safety of our universe's existence may depend on your baseball team stinking like death for the rest of eternity.
  • That said, GoodFellas codified The Mafia in contemporary fiction, especially at a time when romanticized iterations like The Godfather were already becoming outdated. As expected, it went on to become one of the most imitated, referenced, and meme-ified films in recent memory, even outside the mafia genre.
• Groundhog Day was not the first film to introduce the concept of a Stable Time Loop where a person relives the same day over and over; at least two other films did so before, including the 1993 TV film 12:01 PM, as did the 1992 Star Trek: The Next Generation episode "Cause And Effect", but it became the trope namer and trope codifier for the "Groundhog Day" Loop trope.
• Although many consider that Iron Man (2008) defined the style and formula of the superhero movies of the 2010s, many believe that Guardians of the Galaxy (2014) contributed in part to the style of humor used by the Marvel film franchise. Before then, superhero movies couldn't be in the middle — either they tried to be as realistic as possible or they leaned towards the absurd, with the line between being very fine.
• The Hollywood Nuns trope owes itself largely to three films. The Song of Bernadette (1943) was the initial Trope Codifier, and The Nun's Story (1959) and The Sound of Music (1965) solidly reinforced the trope. Because they were so popular, they were used as templates for nuns in film forever after.
• Though not the first of kind, Indiana Jones combined many characteristics from multiple predecessors (some of whom existed way before his 1981 debut) to create the living image of the Adventurer Archaeologist. Besides his films being a Genre Throwback inspired by 1930s cliffhangers, they also repopularized (and helped cement for more modern viewers) the concept of Two-Fisted Tales.
• The idea of domestic dinosaurs in the modern day wasn't that new in the '90s, not even the idea of a dinosaur park, and even if the novel was already popular, the movie of Jurassic Park (1993) is the staple of a dinosaur park that everyone wanted to visit (even if the point of the story was the contrary). Also, it is considered as an staple of digital effects in cinema, a technology that wasn't that new at the time (Terminator 2 and The The Abyss made a good example of that) but in terms of creatures so realistic that even later entries in the franchise show their dinosaurs faker than the ones in 1993 and 1996. Not to mention all the tropes related to dinosaurs. If works have scaly and oversized Velociraptors, spitting Dilophosaurs, gentle sauropods, a based on movement-attacking monster or a battle between a T. rex vs. an Spinosauroid dinosaur, be sure they were watching Jurassic Park a lot.
• While King Kong (1933) was an Ur-Example of an early Attack of the 50-Foot Whatever, it was the film Them! that codified the tropes that other films featuring giant insects would later use (or in general, almost anything, as shown by the Trope Namer Attack of the 50 Foot Woman).
• Examples of Giggling Villain go at least as far back as Arthur Conan Doyle and Sherlock Holmes, but the Trope Codifier is deeply deranged giggling psychopath Tommy Udo in Kiss of Death (1947). Richard Widmark's performance became iconic influenced, among other things, the portrayal of The Joker in various Batman adaptations.
• Lassie is the codifier for the Heroic Pet Story. While not the first Action Pet, she is the most iconic and helped kickstart the genre.
• Lethal Weapon 2 laid out the blueprint for criminals invoking Diplomatic Impunity to commit crimes without the slightest fear of reciprocity.
• The Mad Max franchise is the most well-known example of the Post-Apocalyptic genre. Although it wasn't the first to use the idea, it did pioneer the standards on how the genre should be done, from a futuristic and bleak desert landscape, to scrappy resources, to crazy punk fashions, to the mad and totalitarian society; every apocalyptic film after that had a pint of influence that came from the series.
• While the concept of the Shared Universe is something that's crossed over from several genres of fiction over the years (making it quite hard to determine the Ur-Example), the Marvel Cinematic Universe has established itself as the most famous (and successful) depiction of it, branching out numerous franchises, properties and settings all derived from the comics into one overarching (and ever-evolving) story, to the point that its success has led to many other franchises using its blueprint as the bedrock for expanding into their own cinematic universes in recent years, with varied levels of success. The Trope Maker of this trope likely goes to Hammer Horror, as they were the first studio to depict famous horror monsters interacting with each other in the same setting. And they did it way before Stan Lee, Jack Kirby and Steve Ditko made Marvel Comics what it is today.
• The Mask (1994) is the most famous example of Heart Beats out of Chest, while Tex Avery was the Trope Maker.
• Mr. Vampire was not the first of jiangshi genre films; jiangshi movies were made as early as 1936! However, Mr. Vampire definitely set the standard for them and helped propel the genre into popular from 1985 to the mid-1990s in East Asia.
• Night of the Living Dead (1968): Inspired by I Am Legend, the movie codified the basic elements of a Zombie Apocalypse and defined the characteristics of a Flesh-Eating Zombie.
• Speaking of which, James Cameron wasn't the first to made an entire world in CGI. Movies like The Phantom Menace could be considered as a precursor with the planet Coruscant, but Avatar was promoted as this alien world completely made for immersion in theaters.
• Even if the fantasy setting mixed with pirates existed before Pirates of the Caribbean, many tropes from the movies were cemented in popular culture for this setting specifically, such as the Kraken or the Fish People.
• 1972's The Poseidon Adventure pretty much established the template for future disaster movies, despite sharing many elements with earlier entries of the genre like A Night to Remember.
• Predator codified the alien proud warrior race, even if that trope existed before in series like Star Trek.
• Rebel Without a Cause and American Graffiti made the teen movie a popular and profitable genre with its use of teenage wangst and parties, that teenagers around the world loved and related to. However, films such as Mean Girls and American Pie innovated the genre further by adding pre-marital sex and fascist school hierarchy to the mix, to the point that years later, other teen films are still duplicating these elements.
• Although the onryō dates back to 8th century Japanese beliefs, The Ring and Ju-on helped characterize the onryō as a Stringy-Haired Ghost Girl.
• Rocky (1976) is the most well-known sports film that introduced the underdog archetype to the modern viewers.
• Rosemary's Baby and The Omen give the Antichrist a modern look.
• Saw I and its sequels are definitely this for Torture Porn. Whilst the Trope Maker is often debated, many point to either Cannibal Holocaust, Salò, or the 120 Days of Sodom or The Last House on the Left.
• Scream (1996) popularized Postmodernism for slasher movies and the larger horror genre. Older horror films, such as the 1960 movie Peeping Tom, did have meta elements, but Scream's meta elements were more blatant as its slasher villain Ghostface quizzed his victims on slasher movie trivia. Furthermore, the main characters were Genre Savvy teens who knew the general slasher tropes; for example, the resident movie buff straight up lists the rules of a horror movie in one scene.
• The Social Network is generally considered the codifier for the Moody Trailer Cover Song, with it's trailer featuring a cover of Radiohead's Creep sung by a choir of children. What makes it stand out slightly from the trailers it would inspire is that the original song was not much more upbeat.
• Star Wars:
  • The original trilogy the Trope Codifier for Joseph Campbell's Hero's Journey (as well as a heck of a lot of other ideas). Campbell described the pattern based on a range of heroic myths, but today, any good story that follows the Hero's Journey pattern is accused of ripping off Star Wars — and any bad story that follows the Hero's Journey pattern actually does.
  • Star Wars (along with Alien (1979) and Blade Runner) was also instrumental in making the Used Future concept widespread.
  • The Old-School Dogfight was popularized by the films' use of it as an homage to World War II air war films, with the Death Star trench run in A New Hope in particular inspired by The Dam Busters.
• Sunset Boulevard, and more specifically the character of Norma Desmond is likely the codefier for the White-Dwarf Starlet trope. Norma was one of Hollywood's biggest stars in the era of silent films, but faded out of relevance with the emrergence of talkies. Nowadays (for the time of the film, at least), she's mostly a shut-in, watching her old pictures and beliving that she's still greater than modern stars and that she'd still be able to star in at least one more major film. There's a heavy does of Reality Subtext here, as she's played by Gloria Swanson, who was also one of the biggest stars of the silent era but never was able to transition into talkies (although she was a lot less like Norma as many believe, as after the silent era of film she did remain active in television and theatre). What's interesting is that Gloria and by extension Norma are among the first generation of white dwarf starlets, as Hollywood was at that point new enough that it's earliest stars were getting old, and Norma was one of the earliest and most prominent depictions of this phenomenon in fiction.
• Terminator 2: Judgment Day established itself as the definitive Trope Codifier of the '90s Anti-Hero archetype through its three main protagonists —Sarah Connor, John Connor, and the T-800 — who embody a distinct blend of relentless cynicism, mastery of advanced weaponry and technology, ruthless tactical efficiency, pragmatism, and a rejection of traditional moral idealism.
• This Is Spın̈al Tap: The Codifier for the feature film Mockumentary genre. The Trope Maker is probably Woody Allen's Zelig, released just one year before (1983). The older example, The Rutles' All You Need Is Cash (1978), was a television film.
• Triumph of the Will was this for certain cinematographic techniques. It is not this for the documentary genre (it is almost completely bereft of commentary — the subject material get to stand on its own, it's just that it is cleverly filmed and ordered to encourage the "right" emotion), but this doesn't really help film historians in dealing with it. It also helped that it had the resources of an entire totalitarian state and a genuinely talented (if ideologically misguided) director to throw at any issues that might have arisen. Think about it; the Nazis wanted you to think of this movie when you thought of them — and scenes from this movie are among the most commonly used shorthands for the Nazis.
• An earlier work by William Gibson coined the term "Cyberspace". Both Neuromancer and TRON (1982) set the standards for what we think of it. TRON was also the codifier for Living Program.
• While Steampunk existed before the 1998 film Wild Wild West, the movie brought it into the mainstream for the first time, combining Victorian aesthetics with pre-electric machinery.
• The Wizard of Oz (1939): While the concepts of the scheming Wicked Witch and the black-wearing, crone-like Witch Classic are old, the film's portrayal of the Wicked Witch of the West set the tone for most modern depictions of these and in particular for the popular convention of depicting a Wicked Witch as green-skinned — earlier depictions didn't really depict witches as having particularly noteworthy skin colors, with the choice for green makeup here seeming to have been driven by a desire to show off then-recent technicolor filmmaking.
• The 1941 film The Wolf Man codified the tropes for werewolves, as well as being the Ur-Example of several tropes such as silver bullets, the famous poem about the curse, and the contagious nature of werewolf bites — before the film, weakness to silver and contagion were vampiric traits.
• The John Woo movies and the more recently remembered The Matrix codified the Bullet Time trope.
• Ed Wood's entire filmography is credited with establishing the So Bad, It's Good trope in cinema after he was named "The Worst Director of All Time" by the Golden Turkey Awards in 1980.
• You Only Live Twice and other Bond films featuring Ernst Stavro Blofeld are the codifier for many supervillain tropes, including the Volcano Lair and/or Elaborate Underground Base, Right-Hand Cat, Blofeld Ploy, Shark Pool, and color-coded Mook jumpsuits.

• The earliest use of Ancient Astronauts is Edison's Conquest of Mars from 1898, but the first popular story to use the concept was At the Mountains of Madness from 1931. Even so, the space invation of Edison created a lot of tropes for future space operas.
• Baccano! popularized the Cast Full of Crazy trope, with everyone (across three storylines, no less) being horribly broken, downright unhinged, or just plain nuts.
• While Japanese stories like Kaiji predate it, Battle Royale codified the death game genre in East Asia and eventually became the eponym for battle royale video games.
• We is the Trope Maker for dystopic fiction, but Brave New World and Nineteen Eighty-Four are the codifiers.
• Stephen King's Carrie is the Trope Codifier for Prom Wrecker. Many examples of the trope involve something nasty being dropped on someone, usually the Prom Queen.
• Raymond Chandler is considered the codifier of hard-boiled crime fiction, following Carroll John Daly as the Ur-Example (his "Knights of the Open Palm" was published several months before Hammett's first Continental Op story) and Dashiell Hammett (the Trope Maker).
• Robert E. Howard's Conan the Barbarian codified the Barbarian Hero — and many other Sword and Sorcery tropes, at least among those he wasn't the Trope Maker for.
• The Count of Monte Cristo is codifier for the Came Back with a Vengeance story.
• Discworld codified the Flat Planet on a Turtle trope in The '80s. It's actually a very old myth that had been used by several authors before, but Terry Pratchett's version is by far the best known.
• While Dracula was the first modern codifier for vampiric tropes, The Vampire Chronicles by Anne Rice was a subversion that served to codify the current template used by everyone from White Wolf's Vampire: The Requiem to The Twilight Saga and Underworld (2003). Both kinds of vampire are still in active use, of course. With one exception: for easily understood reasons, most successors have thrown out Anne Rice's vision of vampires as lacking sufficient bloodflow to get it up.
• The Standard Fantasy Setting's Trope Maker was The Lord of the Rings; the Trope Codifier was Dungeons & Dragons.^note As a minor footnote, the concept of a Trope Codifier was originally suggested by the fact that Dungeons & Dragons clearly pioneered and set in stone many elements of the Standard Fantasy Setting, but didn't seem to qualify for full Trope Maker status. As Terry Pratchett once put it, Tolkien's influence appears in modern fantasy the way Mt. Fuji appears in Japanese art — and if it doesn't, either the author is deliberately facing away, or they are standing on Fuji. Ur-Examples go back to mythology, but early 20th century writers such as Lord Dunsany seem to have influenced both Tolkien (a little) and D&D (a bit more). One key trope that doesn't come from Tolkien is Vancian Magic, which was made by Dying Earth and codified by D&D, and Poul Anderson was a big influence on, just for one example, D&D's trolls.
  • D&D can also be seen as the Trope Maker for Fantastic Miniatures War Games (Chainmail was the Ur-Example of a Mini's games heavily featuring fantastic elements, and D&D was originally just the "small warbands" variant of it), but Warhammer and Warhammer 40,000 are the Trope Codifiers.
  • Another Trope Codifier was Terry Books' novel The Sword of Shannara, which showed that Doorstopper fantasy novels that weren't written by Tolkien could also go on to sell zillions of copies.
• Earthsea codified the idea of people and things having "True Names" that give power over them to any speaker in the context of magic systems.
• There have been intelligent and malicious weapons before, but Stormbringer from Moorcock's The Elric Saga is the codifier for Evil Weapon (even for weapons that aren't swords like the Speaking Gun). Stormbringer set the bar for the degree and type of power and treachery in an evil weapon.
• The Eternal Champion was the codifier to the never ending cycle of Order Versus Chaos in fantasy settings (plus, it popularized the Magic of Chaos symbol).
• Expedition was the codifier for bizarre alien worldbuilding for many other projects, with The Snouters: Form and Life of the Rhinogrades and After Man: A Zoology of the Future doing the same for speculative biology. All of those drink from the previous trope creator The Time Machine by H. G. Wells.
• For Want of a Nail is an Alternate History textbook that explores two hundred years of counterfactual events following a failed American Revolution. It serves as codifier for the genre, more specifically, the type common to AlternateHistory.com, which often features narratives presented like a non-fiction description of actual events.
• Allan Quatermain from the H. Rider Haggard novels is considered to be a codifier of the Gentleman Adventurer. Ironically, he isn't even the example in the novel that codified the trope, and Quatermain is way more respectful to other civilizations than his contemporaries.
• Contrary to what some fans believe, Harry Potter didn't originate the Wizarding School trope — but it is such a prominent codifying example that everything that comes after (and some things that came before) will have to either Follow the Leader or strenuously differentiate itself from Hogwarts.
• James Bond defines the most popular image of Spy Fiction. Virtually every fictional spy in later stories has their roots in the Bond character, or will sooner or later be defined by how unlike Bond they are.
• James Fenimore Cooper's The Leatherstocking Tales coined more than a few Adventure tropes, pretty much creating everything we'd expect to see in stories set on the American Frontier. They include Injun Country, Noble Savage and The Gunslinger.
• The Man in the High Castle was one of the main exponents of the codifiction of Alternative History, but stands as the most popular of its time.
• Medea is the Trope Codifier for the Woman Scorned, although Ishtar from The Epic of Gilgamesh is the oldest known example.
• Jonathan Swift's A Modest Proposal is regarded as the codifier of the Stealth Parody.
• The climax of The Monkey's Paw is the Trope Codifier for Ominous Knocking.
• Mushoku Tensei: Jobless Reincarnation, building off of Sword Art Online as the Trope Maker of modern isekai stories (see below), established the basic conventions of Reincarnate in Another World stories. Unlike SAO, its parallel world was a real place instead of a video game (the Six-Faced World) with its own worldbuilding, and it also introduced mainstays of the isekai genre such as a group of heroines for the main character to romance (Eris, Roxy, Sylphiette), use of Deliberate Values Dissonance for a grittier tone (e.g. slavery and aristocratic politics), and a divine character as a Mentor Archetype for the hero (Hitogami, although they turn out to be the story's Big Bad).
• The Phantom of the Opera is a major Trope Codifier for supervillains.
• Miss Elizabeth Bennet from Pride and Prejudice is the trope codifier of Spirited Young Lady. There are some earlier examples (going back to snarky noble ladies from Shakespeare's plays), but none is that influential and widely referenced as Lizzy Bennet.
• When it came to geek-related reference overdosed meta-universes, Ready Player One is essentially both the Trope Codifier and the Ur-Example, at least in literature. Other influential works from this genre are the books Escapist Dream and Otaku Girl. The former focused more on 1980s pop culture while the latter two emphasized more on 2010s internet geek culture.
• The Red Badge of Courage codified War Is Hell.
• Rosemary's Baby and The Omen (1976) cemented the modern version of The Antichrist. In response, Good Omens would make a parody of those tropes with the Anti-Anti-Christ.
• Shakugan no Shana and The Familiar of Zero popularized the Tsundere stereotype.
• Sherlock Holmes is the Trope Codifier for many detective tropes; Edgar Allan Poe's C. Auguste Dupin stories were the Trope Maker, featuring such tropes as the less astute Watson figure as narrator and the far-reaching deductions based on attention to seemingly trivial details. A second contender, wildly popular at the time but now more obscure, is The Moonstone by Wilkie Collins. It placed such concepts as the private detective helping out the near useless police and the Locked Room Mystery into the popular consciousness a few decades before Doyle's novels.
• Snow Crash is widely recognized as the codifier for The Metaverse and the Digital Avatar but William Gibson did them first.
• Space Cadet and Starship Troopers popularized military alternatives in space exploration, with the latter also the codifier of Powered Armor and Bug Wars. Both were made by Heinlein.
• Sword Art Online:
  • The protagonist, Kirito, popularized the concept of the Stock Light-Novel Hero, with the archetype of a dark-clad, sword bearing protagonist with a calculating mind and known for his wits becoming a mainstay of the medium.
  • While the Portal Fantasy has been a well-known genre in both sides of the pond for decades (with Japan itself having major titles in the genre for anime and manga like Inuyasha and Digimon Adventure from the 90s), Sword Art Online popularized its later Japanese incarnation of what is most popularly known as the Isekai ("Another World") genre today, with numerous other Light Novel series following suit. The main character being a Escapist Character trapped in a world that is almost always a medieval fantasy land that runs on typical JPRG mechanics is an especially common setup. Interestingly enough, Sword Art Online itself isn't quite that, since it's set in an actual video game that the protagonist is trapped in; however, subsequent works that follow in its footsteps tend to use a fantasy world that has RPG mechanics in it, but is real otherwise.
• The Tale of Zatoichi: Almost every fictional Blind Weaponmaster takes inspiration from Zatoichi, a blind swordsman with superhuman senses and skill.
• Treasure Island consolidated the popular image of pirates in fiction, so much so that historians are tired of debunking the inaccuracy of the novel.
• The Twilight Saga is the codifier of the mainstream Paranormal Romance genre.
• Watership Down and Warrior Cats are this to the Stray Animal Story and xenofiction genres. The former helped solidify aspects of the genre and popularize the genre. The latter helped popularize more "mainstream" and less fantasy-heavy variations on the genre.
• Jules Verne is often considered the father of science fiction and was influential in the adventure genre too. Naturally, he was the codifier for a few of their tropes.
  • Absent-Minded Professor: French geography professor Jacques Paganel, In Search of the Castaways.
  • Captain Nemo Copy: Captain Nemo, obviously, from 20,000 Leagues Under the Sea.
  • Suicide by Assassin: The plot of Tribulations of a Chinaman in China.
  • World Tour: Around the World in Eighty Days.
• Similarly, the subject of the above-mentioned Wells, his most famous works were codifiers for science fiction.
  • The Invisible Man codified invisibility tropes such as the Invisible Jerkass.
  • The Island of Doctor Moreau codified the Mad Doctor and Beast Men.
  • The Time Machine codified the Time Machine.
  • The War of the Worlds (1898) codified the Alien Invasion.

• The Addams Family (1964) for Creepy Good. May be the maker as well. They're creepy and spooky and altogether ooky but generally loving and benevolent.
• American Idol would very well be the Codifier for Talent Show (Star Search is likely the Maker). It is also both the Maker and Codifier of not only entertaining viewers with the talent of its contestants but also with an "eccentric" judging panel as well as the audition sections, which often contains plenty of Funny Moments.
• Despite the name, Dawson Casting was neither made nor codified by Dawson's Creek; Beverly Hills, 90210 does the codifying honors there. Possible Trope Makers include Bye Bye Birdie, in which 21-year-old Ann-Margaret played the 16-year-old-lead, and the many 1960s beach movies in which Annette Funicello, in her late thirties by the time the last ones were made, played ostensibly fresh-faced debutantes.
  • 90210 is also the Trope Codifier for a Teen Drama; it borrowed heavily from Degrassi Junior High and, besides adding the too-old "kids" moved the setting from a nondescript part of Toronto to one of the shiniest places the writers could think of. Two things most teen dramas since have kept in the mix.
• Breaking Bad was the Trope Codifier for contemporary stories about organized crime and modern portrayals of Hispanic drug cartels — especially considering that it discarded the outdated '80s tropes seen in Miami Vice and anything related to The Mafia, a topic that today feels obsolete, overexposed, and out of touch with contemporary reality — opening the door to brutal depictions of cartels operating in eerie, desolate locations in the Southwest and laying the groundwork for works like Sicario, Ozark, and Yellowstone.
• Cheers and Belligerent Sexual Tension. Sam and Diane provided the template for sitcoms to follow. Ditto for the Will They or Won't They? romantic storyline.
• In Reverse Whodunnits, the Trope Codifier is Columbo, with the Trope Maker being R. Austin Freeman's Dr. Thorndyke.
• Doctor Who: It is the Trope Codifier for Reverse Polarity, with many other shows using it as a Shout-Out to the franchise.
• Everybody Loves Raymond was hugely influential to later sitcoms and is a codifier for All Women Are Prudes in sitcoms (the notoriously anti-sex Debra)
  • It was also a reinforcer of the feminist wife who was always right, even if she argued that the sky was kelly green, initially codified by Home Improvement, where wife Jill was a self-admitted feminist and Tim was the one who screwed up 99.5% of the time.
• Steve Urkel of Family Matters is easily the Trope Codifier for Black and Nerdy. He's a brilliant scientist on par with Reed Richards, dresses in Impossibly Tacky Clothes, has a high-pitched nasally voice and an Annoying Laugh, is The Klutz on a truly epic scale, and his weird hobbies include everything from collecting insects to playing polka.
• Game of Thrones is the Trope Codifier for Anyone Can Die, although many regard The Walking Dead as a close second.
• Iron Chef is the Trope Codifier for the Cooking Duel trope.
• The Kamen Rider franchise, while not the first Henshin Hero example (that would likely go to the Ultra Series), is the go-to standard for such heroes.
  • Kamen Rider Ryuki in turn pretty much became the codifier for all of the following Kamen Rider shows, with current series staples such as collectible devices, a Transformation Trinket that has to be carried everytime, and Anti-Hero or pure evil Riders all making their debuts in Ryuki. (The series can also be argued as a codifier for battle royale-esque fiction in Japanese media, though Battle Royale has a larger presence in the public consciousness.)
• Law & Order is the Trope Codifier for the Police Procedural.
• Malcolm in the Middle is the trope codifier for the single camera, on-location, Laugh Track-free sitcom that became popular on United States broadcast television during the 2000's. There were a handful of pre-Malcolm shows that featured such setups, but these (namely The Adventures of Pete & Pete and The Larry Sanders Show, both of which qualify as the Trope Maker of such setups) aired on either pay or niche cable channels as opposed to the then-more popular broadcast television networks.
  • A year before Malcolm premiered, Spaced did the same thing for British sitcoms.
• Monster Garage is the first Gearhead Show to focus on not only building vehicles but revamping and customizing them, which would set the trend for future such shows.
• Mork from Mork & Mindy is the most prominent example of an Amusing Alien.
• The Muppet Show and Sesame Street codified, well, muppet shows.
• Oobi for Bare-Handed Puppetry. Parodies and homages to the bare-hand puppets on Oobi are just as common as unrelated uses of this trope, if not more so.
• The Real World is the Trope Codifier for Reality Shows.
  • Likewise, the hit series The Bachelor codified the romance for Reality Shows.
• Lionel Luthor from Smallville is the Trope Codifier for Magnificent Bastard. The phrase itself comes from the 1970 movie Patton, and was used extensively by Television Without Pity's recaps of Smallville, to describe Lionel and the prodigious wheeling and dealing he engaged in throughout the course of the series.
• The first usage of Sentai doesn't come from Super Sentai, but Katanas of the Rising Sun of Imperial Japan during World War II. The term "Sentai" was relegated after the war, but Super Sentai codified this term for the squadrons with Color-Coded Characters.
• Star Trek did not invent modern science-fiction television; but it made many science-fiction tropes commonplace on television, so much so that it is its own franchise and has influenced almost every subsequent speculative fiction series since, up to and including Heroes.
  • Star Trek: The Original Series did codify the Red Shirt, but in the earliest episodes they weren't actually wearing red shirts.
  • Likewise, it was not the first TV show to have fanfic, organized conventions, letterzines, etc. However, there are ridiculous amounts of Fanfic tropes that can be traced back to Classic Star Trek, and Roddenberry was one of the few pre-Internet series creators and rights holders who didn't actively go on a seek and destroy mission with the lawyers (he laughed it off as free advertising, and being a Dirty Old Man meant the sexually explicit stuff didn't bother him), meaning it was a relatively safe haven for pre-Internet fandom.
• Series/V1983 is the Trope Codifier for Ominous Floating Spaceship and Reptilian Conspiracy.

• Analog: In his role as Chief Editor for the magazine, John W. Campbell became the major codifier for Golden Age Science Fiction as a genre. His editorship standardized the use of tropes such as Humanity Is Superior (and specifically the White Male Lead), Humans Are Psychic in the Future and a certain mandatory hardness, and the authors he nurtured retained his influence long after his death.

• Bauhaus were the codifiers for Goth Rock, setting the idea of the scene and paving the way for future bands.
• The Beatles were the codifiers for The British Invasion, the modern rock band lineup and writing conventions, and, with Sgt. Pepper's Lonely Hearts Club Band, modern recording techniques such as layered, multi-track production.
• David Bowie and Björn Andrésen codified the Ambiguous Gender in the musical landscape, in the west and the east respectively.
• While Clipse were not the first rappers to rap about selling cocaine, their name is pretty much synonymous with the subgenre called "coke rap."
• Dizzee Rascal's debut album, Boy in da Corner, popularized grime, a fusion genre mixing rap with electronic music.
• If this trope is possible on one network, then Hilary Duff is the trope codifier for the current batch of teenage Idol Singers on Disney Channel. Before her, Disney Channel stars didn't really do much outside of the show. After her, Disney practically required all of their actresses to sing regardless of talent.
• While Todd Edwards certainly didn't invent Sampling, he made it into an art form. What he does is he takes sometimes up to 100 samples from different songs and creates new melodies with them. This type of sampling is often referred to as "microsampling", and has since been used artists such as Pogo and Skrillex.
• Billie Eilish is the trope codifier for Bedroom Pop, setting the standard for several artists after her.
• Emerson, Lake & Palmer are almost certainly the codifiers for Rock Me, Amadeus!; they used it far, far more than anyone else had before them and brought classical works like Pictures at an Exhibition to entirely new audiences who otherwise would probably never have heard them. Each of their albums contains at least one example of this trope. Keith Emerson's previous band, The Nice, also did this a lot.
• Gorillaz and especially Hatsune Miku codified the Virtual Celebrity.
• For the Heavy Metal genre and its offshoots:
  • If Led Zeppelin was the Ur-Example and Black Sabbath was the Trope Maker, Judas Priest is certainly the Trope Codifier. They started the standard image of leather, spikes, studs, and denim, removed much of the blues elements that were very apparent in earlier examples of metal (Led Zeppelin was called blues-rock, after all), and made metal cool again in the late 70s. Motörhead also helped in the codifying of metal. They took influence from Punk Rock and from Heavy Metal and, in turn, inspired much of Thrash Metal.
  • W.A.S.P. was the Trope Codifier of heavy metal's image in the 1980s, combining the Judas Priest facade above with KISS and Alice Cooper-style shock rock antics turned up to eleven, unsubtle Satanic imagery, songs about sex, drugs and rock 'n' roll, big hair, pointy guitars and spandex.
  • Metallica, Slayer, and Exodus (Band) are the codifiers for American Thrash Metal, with the vast majority of thrash bands modelling themselves on one of the three. In Germany, the codifiers are Kreator, Sodom, and Destruction (collectively known as the Three Teutonic Kings of Thrash Metal), and in Brazil, the codifiers are Sepultura, Sarcófago, and Vulcano.
  • In the public eye, Cannibal Corpse is generally held responsible for popularizing Death Metal outside the metal underground, but Deicide, Morbid Angel, and Obituary were the trope codifiers in the metal scene, being among the first true bands in the genre. For the Swedish scene, the codifier is generally considered to be Entombed or Dismember.
    • For Technical Death Metal, the codifiers are Atheist, Death, and Necrophagist for "straight" tech, Cynic, Edge of Sanity and Opeth for prog-tech, Suffocation and Origin for brutal tech, and Gorguts for experimental tech.
    • Melodic Death Metal's major codifiers are At the Gates, In Flames, and Dark Tranquillity for the genre as a whole, Children of Bodom for Power Metal/Neoclassical Metal-inspired melodeath, Soilwork for Alternative Metal-tinged forms, Ensiferum for Folk Metal-melodeath fusions, and Wintersun for symphonic melodeath.
  • Mayhem, Burzum, Darkthrone, Immortal, and Emperor are the collective Trope Codifiers for Black Metal, particularly the Second Wave. For the First Wave, the codifiers are generally agreed to be Bathory, Hellhammer, and Celtic Frost.
    • For Viking Metal, the codifiers are Enslaved and Graveland.
    • Silencer and Xasthur codified Depressive/Suicidal Black Metal.
    • Burzum and Darkthrone also codified the one- or two-man studio-only metal band. While not the first metal bands to do this, and not even the first Black Metal bands to do it (see latter-day Bathory for an example), they were the first bands where such and arrangement was a central part of their identities, and given their status as major inspirations for many bands, many of those band unsurprisingly also set themselves up like them.
  • The codifier for Power Metal tends to vary depending on the region, with Helloween and Stratovarius being the European scene's codifiers, Manowar, Jag Panzer, and Manilla Road being the American scene's codifiers, X Japan being the Japanese scene's codifier, and Angra being the Brazilian scene's codifier.
  • Though the genre has existed since The '70s in the form of bands such as Black Sabbath, Pentagram, and The Obsessed, the main codifiers for Doom Metal are generally considered to be Candlemass, Saint Vitus, Trouble, and Cathedral.
    • For Death/Doom Metal, the codifiers are early My Dying Bride, Katatonia and Paradise Lost.
    • While Stoner Metal existed before Electric Wizard, the band in general and their third album Dopethrone in particular are what cemented the genre as a force in the metal community.
    • The codifiers for Sludge Metal are generally agreed to be Crowbar and Eyehategod.
    • Isis is considered to have codified Post Metal, with Neurosis being the Trope Maker and Godflesh being the Ur-Example.
  • Nine Inch Nails, Fear Factory, Rammstein, and Marilyn Manson are all pretty much equally responsible for popularizing Industrial Metal, the former two moreso earlier, and the latter two moreso later on. In terms of influence, however, Fear Factory undoubtedly had the most impact.
    • Fear Factory also codified the one-man Soprano and Gravel technique. While similar vocal styles had existed in both metal and punk since the 1960's, Fear Factory was the first band to use the contrast between clean and harsh vocals as a key element in their sound, paving the way for dozens of Groove Metal, Melodic Death Metal, and Metalcore bands since.
  • Dream Theater may not have been the first Progressive Metal band, but Images and Words is the album that defined the style and what the entire genre is built upon.
  • While Pantera's status as Groove Metal's Trope Maker is debatable (whether they or Exhorder hold the status as the "first" groove band depends on who you ask), they undoubtedly were the band that set the tone for the rest of the genre from them onward.
  • The Trope Maker of Avant-Garde Metal was probably either Celtic Frost, Voivod, or Atheist, while Mr. Bungle or Korn are sometimes considered Trope Maker for experimental. Therion is generally considered to have codified avant-garde metal while Enter Shikari codified modern avant-garde. Faith No More are considered trope codifier for experimental metal, Meshuggah for djenty experimental (as well as being Trope Maker for djent), and System of a Down for modern experimental. The eastern scene has its own codifiers, Dir en grey, Sigh, Sound Horizon, and Fear And Loathing In Las Vegas.
  • Korn are also considered the Ur-Example for Nu Metal, Coal Chamber (whose work initially coined the term) the Trope Maker, and the Big 4 of Limp Bizkit, Slipknot, Linkin Park and (debatably) Disturbed codified the genre leading into the early 2000s.
  • Music resembling Symphonic Metal has been around since Deep Purple performed Concerto for Group and Orchestra in 1969, but Nightwish and to a lesser extent After Forever and Therion largely codified the subgenre in the late '90s and early 2000s. Nightwish is particularly important in symphonic metal's frequent overlap with Power Metal, and for it being one of only a handful of music genres to be utterly dominated by female lead vocalists, usually ones with classical and/or opera training.
• Janet Jackson codified many tropes for female pop/R&B singers in the decades since she became popular, such as her performance style, fashion and even her ability to crossover into the mainstream from R&B music (which historically has been somewhat difficult for non-white artists). More specifically, her dancing and performance style has been cited as an influence by a variety of musicians, from Britney Spears, to Usher, to *NSYNC, to Beyoncé, to Lady Gaga.
• By the time of Michael Jackson, music videos were evolving beyond just shots of the band, but he set the standard for everything that came after him.
• Kraftwerk is the Trope Maker of Electronic Music, and Aphex Twin is the Trope Codifier with his seminal Selected Ambient Works 85-92 album.
• Despite BUCK-TICK and X Japan being prominent early examples, Kuroyume set the template for nearly every Visual Kei band that followed, including better known (at least in the West) examples such as Dir en grey and Luna Sea.
• LL Cool J's "I Need Love" is considered the first rap ballad (though the Ur-Example would probably be Sugarhill Gang's 1982 song "The Lover in You"), showing that rappers need love too. Because of this song, even the most gimmicky One-Hit Wonder-y rapper will release at least one slow love song.
• With Indie Pop rising to popularity in The New '10s, Lorde quickly became the codifier for the genre. Not only for "Royals", one of the biggest indie pop hits ever, but also for Pure Heroine, which was quite possibly the most successful indie pop album of its decade. Billboard even named her the "Queen of Alternative."
• Ichiro Mizuki is widely credited as the maker and/or codifier of the animusic genre. There's a reason he was known as The Emperor of Anime Songs and referred to as "Aniki"/"Big Brother" by not just his fans, but just about everyone in the entire Japanese entertainment industry.
• Nitzer Ebb combined many of the particulars of early EBM bands and brought all the elements together for the sound that most EBM bands afterward would follow. Front 242 created the name EBM, and DAF (or perhaps Kraftwerk) had many of the elements of the sound, but Nitzer Ebb would be the model for the future.
• The Notorious B.I.G. and Tupac Shakur are the joint codifiers for Gangsta Rap.
• Ol' Dirty Bastard's feature on the remix to "Fantasy" by Mariah Carey codified A Wild Rapper Appears!, with rap features on radio-friendly pop singles becoming much more common after this song's success.
• While he was not the first to do it or even make a full album out of it, John Oswald was the one who gave the name to the genre Plunderphonics and also its very identity with his album Plunderphonics.
• Pink Floyd is the Trope Codifier for the usage of Bookends in music, incorporating it on many of their albums (The Dark Side of the Moon (1973) has a Heartbeat Soundtrack, Animals and Wish You Were Here (1975) have one song split into the opening and ending tracks, The Wall's ending segues into the opening).
• For the Punk Rock genre and its offshoots:
  • The Ramones are considered to be the Trope Makers. Not only did they inspired others to imitate their music, they were also the first band in history to be called a punk band (though they disliked it). However, it was the British bands such as the Sex Pistols and The Clash who created the modern punk image. Sex Pistols themselves were the first ones to add genre staples such as cursing, politics, and moral views, making them the Trope Codifier of Three Chords and the Truth. These U.K. bands were the ones who invented punk ideology.
  • The Sex Pistols' songs such as Anarchy in the UK and God Save The Queen are considered to be the first modern punk rock songs.
  • For the Hardcore Punk subgenre, the codifiers are considered to be Black Flag, Bad Brains, and Minor Threat for the Eastern United States and Dead Kennedys for the Western United States.
  • For Post-Punk, the codifier (and arguable Trope Maker) is Joy Division.
    • Interpol is the second codifier for the genre. They led the revival movement for the genre, and pretty much every Post-Punk band after was influenced by them.
  • For Pop Punk, the codifiers are generally considered to be Green Day and The Offspring (with some also crediting blink-182). The concept of combining fast, aggressive music with pop melodies, however, was invented much earlier by bands like Buzzcocks, The Undertones, and the aforementioned Ramones.
• If you see a Greatest Hits Album with a title like Notable Song by the Artist or Thematic Word Related to Artist: The [Artist] Story or An [Artist] Anthology or The Best of [Artist] (Year-Later Year), with a career-spanning tracklisting and extensive liner notes and credits, it's following the template Rhino Records established for their successful reissue compilations in starting in The '80s, specifically with the compact disc format in mind.
• Pierre Schaeffer's 1948 opus Cinq Études de Bruits was not the world's first musique concrète. John Cage's Imaginary Landscape and perhaps other such works predate it. But it was the first music to have that label (coined by Schaeffer), and codified the genre.
• Skinny Puppy was the codifier for Industrial music's current, electronica-influenced sound; before them, Industrial tended to be a dark, dissonant, and experimental affair.
• Seo Taiji and Boys provided the Trope Maker for modern Korean Pop Music conventions like the use of English phrases, the focus on dance, and Western music (most notably hip-hop) influences. These conventions would be codified by SM Entertainment, which used them as a template for modern idol formula with the Boy Band H.O.T. and later the Girl Group S.E.S. SM would later introduce the concept of some groups having large rosters with Super Junior (which debuted with twelve members) and Girls' Generation (which debuted with nine members).
• Using Auto-Tune for a robotic effect didn't become prominent until the arrival of T-Pain in 2005. Unlike other artists that relegated it to subtle uses or genres aiming for a digitalized sound (such as electronica or techno), T-Pain used it obviously and flagrantly on nearly all of his releases. His huge success led to a slew of imitators within pop, R&B, and hip-hop.
• While songs complaining about how much jobs suck have existed since the invention of jobs, "Sixteen Tons" by Merle Travis (later made popular by Tennessee Ernie Ford) is the leading example that all modern Working Class Anthems owe one to; a song about the day-to-day of a working class man who's laborious job is a constant cycle of paying of debts and feeding back into the very business they give their lives to.
• Tina Turner is the trope codifier for female diva singers with over the top wardrobes. She specifically has influenced female African-American singer such as Beyoncé.
• Vaporwave has two. For first-wave vaporwave (2011-2013), Vektroid's Floral Shoppe album under the pseudonym MACINTOSH PLUS was easily the most popular vaporwave album. For second-wave vaporwave, that title belongs to 2814's Birth of a New Day album. Case in point? It was featured in Rolling Stone.
• Richard Wagner coined the term "leitmotif" in an 1851 essay and codified the concept in his famous cycle Der Ring des Nibelungen, which he had been working on at the time. But the trope was invented two decades earlier by Hector Bérlioz, who called it "idée fixe" in his own writings.
• "Weird Al" Yankovic codified the Song Parody.
• Kanye West popularized the Chipmunk Soul production style in hip-hop.

• Under John W. Campbell, Astounding Science Fiction became the major codifier for Golden Age Science Fiction as a genre. His editorship standardized the use of tropes such as Humanity Is Superior (and specifically the White Male Lead), Humans Are Psychic in the Future and a certain mandatory hardness, and the authors he nurtured retained his influence long after his death.

• Big Van Vader and The Undertaker are the trope codifiers for the Wrestling Monster, drawing on the earlier "wild-man" characters of Wild Red Berry, Gorilla Monsoon, and George "The Animal" Steele (themselves swiping the gimmick from carnival sideshows) adding in an elaborate Backstory in the case of Vader (written by the famed Go Nagai no less!) and some truly impressive special effects in Taker's case.
• CMLL's mini estrellas were the trope makers for having the same gimmick on multiple luchadores of different sizes, most notably Mascara and Mascarita Sagrada, but AAA codified the idea with its mascot division, where every tag team/pareja had to be made up of a larger luchador and smaller mascot/smaller luchador and larger mascot.
• Hulk Hogan is the codifier for the All-American Face, given that his name has practically become synonymous with the archetype.
• Stacy Keibler was WWE's codifier for Cute Bruiser (Terri Runnels being the Trope Maker and Tammy Lynn "Sunny" Sytch being the Ur-Example).
• The Lucha Libre Internacional match in 1977 featuring Huracán Ramirez and Black Shadow teaming up with El Santo to face Negro Navarro, El Signo and El Texano, the latter team becoming known as "Los Missioneros de La Muerte" in the aftermath of a truly frightening rematch with Rayo de Jalisco Shadow's place, is what made the six man "tercias" match the most popular match type in Mexico and synonymous with Lucha Libre. Blackman, Kato Kung Lee and Kung Fu are, in turn, the trope codifier for the tecnico trio as Los Tres Fantásticos, since Los Missioneros de La Muerte's prior feud had really been more about Santo, with his partners there to make things even, rather than being a unit in their own right.
• Sable set the standard for what a WWE Diva was supposed to look like. Previous women who wrestled had been less glamorous and had dressed more modestly.
• All Japan co-founder Akio Saito popularized the sit down powerbomb in the United States, which would later be taken up by the likes of D'Lo Brown(a running variant) and Batista.
• "Superstar" Billy Graham created the "flamboyant bodybuilder" wrestler archetype as we understand it today, directly inspiring Hulk Hogan — and, also, probably serving as wrestling's Trope Maker for Real Men Wear Pink. (Buddy Rogers and Ric Flair also had blond hair and tanned skin, but they didn't really have the muscles.)

• The Goon Show (and the work of Spike Milligan in general) is the codifier for Surreal Humor.
• The Trope Codifier for combining the Brainless Beauty and Dumb Blonde tropes into one character might have been the enormously popular late 1940s radio sitcom My Friend Irma starring Marie Wilson as the very pretty but oh so dim Irma. The series would spin off into feature films, a television series in the early 1950s and a long running comic scripted by Stan Lee!

• Champions/Hero codified point-build systems, closely followed by GURPS, which seems to be the codifier for "system designed as generic from the start."
• Dungeons & Dragons:
  • It managed to be both maker and codifier for tabletop — and to only a slightly lesser extent, computer — role-playing games in general. Even games totally unlike D&D usually have to be defined in terms of how they differ from it, when speaking to people not already familiar with the hobby (and to some people who are).
  • D&D also either made or codified a whole slew of more specific gaming tropes, including Armor and Magic Don't Mix, Character Class System, Linear Warriors, Quadratic Wizards, and so forth.
  • D&D also codified "Magic A" Is "Magic A". Even if Vancian Magic remains uncommon, the idea of magic as a force with dramatic effects and precisely defined limits that any human can learn if they're smart enough traces right back to the Player's Handbook — after all, it wouldn't be very well-designed for magic to have no rules. As with many tropes, it's something that usually gets associated with "Tolkien-style fantasy" despite Tolkienian magic having none of these traits.
  • It's unclear whether or not Advanced Dungeons & Dragons was the first to present an alignment system beyond good/neutral/evil^note Dungeons & Dragons used Lawful, Neutral and Chaotic for alignments. AD&D picked up from there and added good and evil as modifiers to all three., but it was definitely the most prominent, and its nine-point alignment system comprises all of the Character Alignment tropes today. Ironically, the most recent version of the game has done away with the alignment system, for the most part.
    • The Order Versus Chaos aspect was borrowed from Michael Moorcock and Poul Anderson, for what that's worth.
    • Original D&D only used Law/Neutral/Chaos. Later in the Strategic Review (the forerunning of Dragon), Gygax penned an article with five alignments: Neutral plus the four pairs using Good/Evil crossed with Law/Chaos. This version was used in Holmes's Blue Book Basic D&D. Soon after, the AD&D PHB had the nine-fold system.
  • While the connection might be coincidental, The Nolan Chart (a Trope Codifier in its own right) was published in 1971 (seven years before the AD&D 1e Players Handbook) as a two-dimensional alternative to the traditional left-right political analysis. Communitarianism vs. individualism might be analogous to law and chaos, but YMMV as to whether free markets are chaotic and good or chaotic and evil.
  • Interestingly enough, Dungeons & Dragons is actually the Trope Codifier for the Trope Codifier trope itself — the idea was developed as a distinct trope from the Trope Maker by noting that D&D, while not the origin of the tropes it popularised, was instrumental in making them the default in the fantasy genre, and looking to see if other works were in the same position.
• GURPS:
  • GURPS quite literally defined the Weirdness Magnet trope. (Blue Devil is the Trope Maker here)
  • With its iconic clean attribute/skill/advantage/disadvantage four-way split, GURPS is probably also the codifier for Skill Scores and Perks. (Champions already did something similar, but blurred the lines by having several distinct types of perks — including an entire build-your-own construction system for superpowers, which it in turn is probably both codifier and Ur-Example for.)
• Although there were Trading Card Games older than Magic: The Gathering (mostly using baseball cards), most of the tropes associated with modern TCGs started with Magic.
• The Zerg of StarCraft may have been the namers for Zerg Rush, but the Tyranids, of Warhammer 40,000, were infamous for the tactic long before the Swarm came around. Of course, with both being based on the Bugs from Starship Troopers the similarities are unavoidable, the result being an odd case where the Trope Namer came after the Codifier.
• Warhammer:
  • The game is a strong contender for the Dark Fantasy genre. While the concept of a less-than-happy fantasy obviously existed before (the fathers of fantasy fiction — J.R.R. Tolkien and R.E. Howard — both contributed to it), many of the typical traits such as the vaguely Central European late-medieval settings or focus on lower classes and social outcasts seem to have been first put together here.
  • Warhammer is also the modern codifier for orcs. Before Warhammer, the iconic orcs of D&D hewed more closely to Tolkien's Uruk-hai, being regimented, Lawful Evil minions of your average Evil Overlord. Orcs being Chaotic Evil tribal barbarians was an invention of Warhammer, where they were portrayed as a satire of Football Hooligans who lived for a brawl and who fought wars like they were pub crawls. They also invented the green skin that would later become a standard. Later editions of D&D, as well as Warcraft, drew more on Warhammer's depiction of orcs as savage, stupid brutes than on the original from Tolkien.
• Warhammer Fantasy Battle, alongside the Warcraft games later on, codified the modern perception of orcs as an imposing, strong, tusked, green-skinned, and warlike Proud Warrior Race usually found living in quarrelsome tribes under war-chiefs and shamans. In the Trope Maker proper, The Lord of the Rings, Orcs are depicted as physically smaller than humans (they are usually compared to Hobbits and Dwarfs) and chiefly dangerous in groups, strongly favoring skirmishing, ambushes, and ranged combat in warfare unless they have overwhelming numerical advantages, having more apelike proportions and human skin tones, disliking the sun and preferring life underground, and having considerable technically skill where machinery and even medicine are concerned — in many ways, they're more similar to typical fantasy goblins than to typical fantasy orcs. Warhammer's depiction of Orcs as hulking, strong, green-skinned and hugely tusked unsophisticated barbarians living in a patchwork of feuding tribes, particularly as filtered through Warcraft's own take on this version with more in the way of Orc heroes, played a major role in shaping what orcs would end up looking and acting like in later media.

• Gilbert and Sullivan didn't invent the Patter Song — there are examples of them going back over a century before G&S appeared on the scene (one early example from Don Giovanni has the Don's servant singing out a Long List of his lovers and tastes). Gilbert and Sullivan made it their own however with two important changes: virtuoso rhymes for Least Rhymable Words that often border on Painful (the Major General Song for example has strategy/sat a gee, hypotenuse/lotta news and century/adventure-y; "Matter Patter" from Ruddigore even manages to rhyme idyll and individual) and a pace so fast that half the fun is just hearing the actors get the words out. Practically every fast-paced piece in any musical from the last century or so has had a little bit of Savoy in it.
• Oklahoma!:
  • Oklahoma! can be considered the Trope Codifier for integrated musicals in general. Prior "musicals" were generally either plays interrupted by occasional songs or flimsy plots that were just an excuse to move between song and dance numbers. Show Boat is usually considered the first musical to integrate song, dance, and story, but it was hard for others to imitate. Oklahoma! provided a template that other musicals used pretty much until Andrew Lloyd Webber showed up.
  • "Laurey Makes Up Her Mind" was the Trope Codifier for Dream Ballets in musicals.
• The Ring of the Nibelung codified the Horny Viking along with a bunch of common Nordic tropes in popular media.
• William Shakespeare used almost entirely unoriginal plots (with his fame coming from executing them brilliantly), so anybody harkening back to Shakespeare for a basic plot is going to the Trope Codifier, rather than the Trope Maker.

Tropes and companies

• The modern Adventure Games were codified by basically every game made by Telltale Games. After that, every new one tried to expand or being different from them, like the ones made by Quantic Dreams.
• Broadly speaking, nothing in any Blizzard game is new or original. They just introduce and tweak the successful elements of previous games to make ones that are quite good. One thing they did create was units giving ever more amusing responses if you won't leave them alone.
• The Explorer Horror genre has several games that popularized it, these being (in order of release) Yume Nikki, Ao Oni, Corpse Party: Blood Covered, Misao and its prequel Mad Father, Ib, and The Witch's House. While the genre dates back to the PC-98, it was these games that became indie sensations, containing many of the tropes that would become genre conventions, and it is rare for an Explorer Horror game to not take at least a little inspiration from them.
• Quick Melee has existed in some form in shooters for a long time, but the Halo series is what started the trend in modern shooters, and the Modern Warfare series and Call of Duty: Black Ops are what made the "press a button to pull out your knife and stab with it in one motion" almost standard in recent shooters.
• The Roguelike genre has two important codifiers: NetHack introduced many features that have since become commonplace in the genre and Angband created a whole, thriving Sub-Genre of its own. Additionally, the Mystery Dungeon series established many standards for roguelikes made by Japanese developers. The Binding of Isaac later set the Rogue-lite sub-genre in stone, with many games following its heavy emphasis on Macrogame progression, large array of items with quirky passive effects, and streamlined gameplay mechanics inspired by more mainstream genres.
• The two most common forms of contemporary Western RPG were codified by Bethesda and BioWare after the genre's crash in the mid-90ies:
  • Daggerfall (and The Elder Scrolls series in general) codified the exploration-driven single-character RPGs whose main appeal is the absolute freedom of movement and a metric ton of diverse side quests.
  • The Baldur's Gate series (and most of BioWare's other games), meanwhile, codified the Player Party-based RPGs whose main appeal are the quirky teammates and the story that presents a ton of moral choices.
  • BioWare's games, especially Dragon Age: Origins, codified the modern variation of Romance Sidequest in Western RPGs, with subsequent works popularizing having the capacity to date party members by giving them gifts and spending time with them, as well as popularizing having at least one Gay Option in games.
• Grand Theft Auto, particularly Grand Theft Auto III, codified the Wide-Open Sandbox genre, while Minecraft codified its evolution into the Survival Sandbox subgenre.
• Any new Wide-Open Sandbox space simulator is highly likely to be compared to at least one of three games: Freelancer, the X-Universe series, and EVE Online. The latter two are better known among younger gamers that may not be familiar with Freelancer^note While Freelancer did come out later than X: Beyond the Frontier, the X series got new entries and continuous updates throughout the the 2000s, while Chris Roberts was in a ten-year vacation from game-making.. Single-player sims are more likely to be compared with X, Egosoft being essentially the only game in town for nigh-on ten years, while MMOs are usually compared to EVE. As a result, Freelancer creator Chris Roberts' single-player/MMO hybrid Star Citizen has drawn comparisons to both. Those games in turn owe much of their formula to the Elite series, the Trope Maker for Wide Open Sandboxes in general.
• Max Payne and the first F.E.A.R. game codified the sometimes called "Woo Shooter", which are basically shooters with Bullet Time mechanics.

Games

• Ace Combat codified flying mechanics in video games.
• Antimatter Dimensions popularised several mechanics found in the Idle Game genre, including polynomial growth (the idea that producer one makes the resource and each one above makes the one below), milestones that would make repeated New Game Plus resets faster and more comfortable, and a mode that makes progress slower when active while producing an exclusive resource.
• Arknights isn't the first Tower Defense game, but it popularized the tower defense genre with more complex gameplay mechanics and a greater focus on story than other tower defense games.
• The Atelier Series, specifically the first two games, Atelier Marie: The Alchemist of Salburg and its sequel Atelier Elie: The Alchemist of Salburg 2, are the reason why most JRPGs released after the year 1998 have an Item Crafting system, as the popularity of these titles (at least in their native Japan) caused most Japanese developers to want a slice of the alchemy pie.
• beatmania isn't the first Rhythm Game; that honor goes to PaRappa the Rapper. However, beatmania established a lot of the conventions that would go on to be the foundation of other rhythm games: Multiple lanes of notes with one lane per button, a timing judgement system that awards points based on how accurately the player pressed the note, and a wide variety of songs about 1-2 minutes each in order to be more accomodating to the three-stage arcade game format.
• Bendy and the Ink Machine codifed Mascot Horror, with Five Nights at Freddy's 1 as the Trope Maker.
• Borderlands codified all the tropes related with the Looter Shooter genre by uniting the genres of First-Person Shooter and Role Playing Games into a single game. Although the RPG and loot system were originally codified by Diablo, Borderlands still deserves this spot for the previously mentioned reason and then some.
• Breakout is the Trope Maker (and Trope Namer) for Breaking Out, but most future examples of the genre are more based on Trope Codifier Arkanoid, which added in power-ups.
• Capcom vs. games for the concept of "tag battle" fighters (discounting wrestling games, which have wildly different gameplay).
• While Dune II is the most likely candidate for the very first Real-Time Strategy, Command & Conquer pioneered many of the features that are present in the genre. Command & Conquer: Red Alert in particular codified and formalized the use of supporting abilities, heavy emphasis on counter-play, and Crippling Overspecialization.
• Dark Souls inspired a trend toward action RPGs with punishing difficulty and bleak, grimdark aesthetics.
• Darkstalkers is the Trope Codifier and possibly Trope Maker for Succubi and Incubi in Japanese video games. Morrigan Aensland as initially conceived by the Japanese was a more masculine character and she was also a vampire, Alex Jimenez then told the other artists about changing her into a succubus to differentiate her from Demitri. The Japanese artists had no idea what a succubus was, so Jimenez explained. The artists were happy with the idea and changed the vampire into a succubus, but still retaining some vampiric visual traits for Morrigan.
• Dead Rising is most likely the codifier for the whole popular "zombie apocalypse from the inside of a mall" trope, even though it was released as recently as 2006. It has been done many time since, notably by Left 4 Dead 2 (released 2009), with the second half of its "Dead Center" campaign, which takes place entirely in a mall. This was most likely an intentional parody of Dead Rising, as Valve had made references to Dead Rising before, like how Dead Rising had an achievement called "Zombie Genocider" which required you to kill 53,594 zombies (the population of the town) while Left 4 Dead (2008) featured an achievement called "Zombie Genocidist" which required you to kill 53,595 zombies, upping it by exactly one.
• On the subject of mods/user-made maps, Defense of the Ancients is not the Trope Maker for Multiplayer Online Battle Arena. The concept was made by Aeon of Strife from the StarCraft I days and DotA itself took or adapted ideas from predecessors in the genre. However, DotA is the best-known example of the type, the first to become big enough to be a competitive title, and it's no great stretch to claim that dedicated games like League of Legends or Demigod would not exist without it.
• Although there were definitely 3D beat'em ups/hack-and-slashers in the PS1/Sega Saturn/Nintendo 64 era, Devil May Cry 1 gave the genre new popularity and credence and is widely seen as the key inspiration for similar "Stylish Action" games like God of War, Ninja Gaiden (the Xbox revival), and spirtual successor Bayonetta (created by Hideki Kamiya, who also created Devil May Cry and directed the first game). Many subsequent titles in the genre either directly take inspiration for it or, via aping direct so-to-speak offspring like aforementioned God of War, indirectly draw from it.
• Disco Elysium is a Detective CRPG that inspired multiple successors like Esoteric Ebb, Rue Valley, Hopetown, ZERO PARADES: For Dead Spies, and Tangerine Antarctic.
• While Recca probably was the Ur-Example and Batsugun was definitely the Trope Maker, DoDonPachi codified various staples of the Bullet Hell genre. And it continues to redefine and codify the meaning of it, seeing as True Final Boss Hibachi would become progressively harder and harder beyond belief.
• Doom and Wolfenstein 3-D by id Software weren't the first First Person Shooters (or even id's first First Person Shooter), but the two games popularized the genre and each inspired dozens of imitators. For a while, first person shooters were often called "Doom clones." While these games are very primitive by today's standards — you can't jump or even look up — Doom remains to this day a partial trope codifier, popularizing deathmatches, FPS games with built in support for Game Mods, telefragging your friends, etc. In fact, John Romero coined the term deathmatch and frag.
• Dragon Quest III is the video game where the Eastern RPG truly became a separate genre from the Western RPG, and set the template for all other JRPGs to follow, including rival series Final Fantasy and Phantasy Star.
• Duke Nukem 3D pretty much started the trend of realistic/organic level design in FPSes. While Quake was far superior from a technological standpoint (being the first all-3D FPS) the environments weren't nearly as interactional as Duke's, which had levels with never before seen interactivity. Light switches, mirrors, CCTVs, wall sockets that electrocute you, televisions, urinals to relieve yourself in, even rooms that make sense (like a bar, hotel rooms, restrooms, nightclubs, and reactors for the moonbase).
• While not the first Extraction Shooter, Escape from Tarkov invented the "Scavenger" subtype that blended the extraction mechanics with the Looter Shooter, and would inspire most works in the subgenre released since.
• The Sanity Meter has cropped up more often in electronic gaming (it had been fairly standard in tabletop horror gaming for a while), and it will always get compared to Eternal Darkness: Sanity's Requiem as a result, especially since that game used the meter to screw with the player as well.
• EverQuest is the Trope Codifier for nearly every single MMO trope of today. While it wasn't the first of its kind (MUDs and Ultima Online get that title), it was the first to establish the model that other MMOs would follow, up to and including World of Warcraft.
• Fallout codified the modern use of retro futuristic alternative history, being maybe the most well known example.
• Final Fantasy VII redefined how stories were told in JRPGs, from the cinematic presentation to the Urban Fantasy setting to the character archetypes, despite its intentions as a deconstruction of the JRPG genre as a whole, and is arguably considered the second major codifier of the genre after Dragon Quest. It also codified the Ominous Latin Chanting trope for video games with the Final Boss theme "One-Winged Angel". While it was absolutely not the first game to have a song with Latin lyrics, it is by far the most popular, and a large portion of video games which have Latin lyrics in the final boss theme are inspired by this song.
• Gears of War took the idea of Take Cover! as an integral part of the gameplay system — as opposed to an organic "hide behind stuff so you stop getting shot" — from earlier games, but the concept's subsequent popularity would most likely not exist without it.
• Even though Doom was the Ur-Example of the Space Marine trope in video games, Halo became the poster boy for the trope for the post-2000 generation. It also didn't actually pioneer any of the revolutions in gameplay it featured (all of them, from limited inventory, to Regenerating Health, to Quick Melee attacks, to separate buttons for firearms and grenades, had been done before in previous games), but it is unquestionably the game which popularized them all to the point that most modern First Person Shooters now use them by default.
• The Legend of Zelda:
  • The Legend of Zelda I codified the Action-Adventure genre, boasting innovations such as a battery save feature and open-ended gameplay, while eliminating irrelevant tropes such as Scoring Points. However, it was predated by Adventure (1979) for the Atari 2600.
  • The Legend of Zelda: Ocarina of Time: Kaepora Gaebora is the Trope Codifier for Shall I Repeat That? His advice tends to be very long, spanning multiple dialogue boxes. The slow Scrolling Text is anything but helpful. When it's over, he will ask "Did you get all that?" or "Do you want to hear what I said again?"... by which point veteran players may well be mashing the "A" button to skip, only to select the default option which will always be the one that asks him to repeat himself, regardless of the question's wording. The Nintendo 3DS port makes the game's text scroll faster, and in the original you can press the "B" button to skip the repeatable sections of his dialogue — which the game never tells you you can do.
• While Limbo and Inside already existed, nearly every game after Little Nightmares chose to model their gameplay after it. Instead of 2D movement in a mainly 3D environment, Little Nightmares and many games that came after it utilized a 3D space with 3D movement while employing 2D camera angles, usually a top-down view (also known as dollhouse view or bird's-eye perspective).
• Rockstar Games' infamous Manhunt is the mascot for video games that supposedly turn people into sadistic killers. This reach the point where, after its release, almost every major murder incident in the world had something to do with the game, and since then, it has been the bane of lawyers and parents alike.
  • Things only worsened with the release of the sequel Manhunt 2, which was playable on the Wii. Yes, you can play the game in near virtual simulation with the Wii Remote as your "weapon".
• Metal Gear for Stealth-Based Games.
• Metroid 1 was the first Metroidvania game, and Super Metroid is the Trope Codifier. The Castlevania series, particularly starting with Symphony of the Night, also helped codify the concept, hence the "Metroidvania" moniker.
• While Modern Warfare wasn't the first game to use an RPG-esque leveling-up system for its multiplayer, you'd be hard pressed to find another online FPS today that doesn't use a system almost exactly like it. It's fairly easy to implement and can keep the player invested for another fifteen to twenty hours that they normally wouldn't have bothered with. It wasn't the absolute first modern military shooter game either, with Battlefield 2 among others preceding it, but most people blame it for making the setting popular, and it also popularised certain setpieces like breaching scenes and player-controlled Death from Above/fire support.
• Pong is usually considered the first Video Game by the general public. The actual first Video Game is debatable depending on how you define Video Game, ranging from an unnamed game of Cathode Ray Tube Amusement Device in 1947 to the 1972-released Magnavox Odyssey game console (the strongest contender turning out to lie smack in the middle, 1962's Spacewar!!), but the consensus is that Pong is the Trope Codifier rather than the true Trope Maker.
• Current RPG/Match-Three Game hybrids take their cues from Puzzle & Dragons, rather than the Trope Maker, Puzzle Quest.
• Quake is the codifier for the "mouselook" control scheme, where instead of only using a keyboard to control an FPS character, you control the view with a mouse as well while using the keys to control the direction of movement for your character: forward-backwards-strafe. Bungie's Marathon is the Ur-Example, Terminator Future Shock is the Trope Maker, but due to Marathon being on the unpopular Apple platform, and The Terminator: Future Shock just not being popular, it took until Quake and its innovative online multiplayer before the mouselook feature became codified.
  • Also, although this one was by mistake, Quake codified Jump Physics for the First-Person Shooter genre such as the Rocket Jump and the Strafe Jump. For the former, it was initially discovered as a glitch, but was left in the game for one reason or another. Later sequels consider this glitch an integral technique, to the point that it's referenced in many games^note the "Launch Command" level of Quake II, the BFG in the map "Hero's Keep" in Quake III Arena, the introductory tutorial in Quake Live, Ranger having self-damage immunity as its passive ability in Quake Champions, you name it....
• Resident Evil:
  • Resident Evil 1 for Survival Horror despite not being the first of its kind (it also codified the zombie virus concept). This also led to a trend of other survival horror games labeling themselves as belonging to a "different" genre of horror to distinguish themselves from Resident Evil, including Capcom's own Dino Crisis using the terminology "panic horror" once the inevitable "Resident Evil... with dinosaurs!" comparisons sprung up.
  • Resident Evil 4 for the Always Over the Shoulder Third-Person Shooter.
• Pokémon is the codifier for the monster-capturing game genre, predated by the Darker and Edgier Shin Megami Tensei series.
• Fighting massive creatures in games isn't anything new, however, after Shadow of the Colossus came along; taking on behemoths would never be the same again. Hence, the Colossus Climb.
• While most certainly not the first Survival Horror game, Silent Hill introduced, or at least popularized atmosphere with limited visibility that maximizes Nothing Is Scarier.
  • Almost two decades later, P.T. (a demo for the cancelled Silent Hills reboot) would itself become the codifier for Unnaturally Looping Location walking sim psychological horror games. The explosion of them in the following decade can be traced back to P.T.'s viral popularity in mid-2014, and many will contain some kind of Homage to the now-defunct original.
• Story of Seasons is both the Trope Maker and Trope Codifier for the Farm Life Sim.
• Street Fighter II codified many a trope related to Fighting Games: Shotoclones (Ryu and Ken), Shoryuken (being a common move of the aforementioned Shotos), Moveset Clones (Ryu and Ken again, also the former Trope Namers), Combos (though by accident), Lag Cancel, having a varied cast with their own movesets as playable members... While other fighting games were created before SFII, none of them could even scratch the surface regarding the impact this game had on the genre.
• Super Mario Bros.:
  • Super Mario Bros. 1 was the Codifier for Platform Games (see The Other Wiki's article on platform games).
  • Bowser and the Spinies enemy type from Super Mario Bros. 1 are the original example that codified the Studded Shell.
  • And Super Mario 64 was definitely not the Trope Maker for 3D platformers (see The Other Wiki's article on platform games), but was definitely the codifier of it, since is what all later games imitated.
  • Super Mario World is the codifier of Power-Up Mount, and the Codifier of Enemy Roll Call.
  • And then we have the romhacks... Kaizo Mario World codified Platform Hell (and, of course, Kaizo Trap).
  • Also worth noting is Mario Party, codifier for the party game genre. Chances are, the trope maker would be its obscure, Japan-only Spiritual Predecessor Getter Love!! (assuming nothing came before that one).
  • Before even Super Mario Bros. was Donkey Kong (1981), which popularized the platformer genre and also codified Throw a Barrel at It.
  • And to further set the point, it cannot be denied that Super Mario Kart is the Trope Maker and Codifier for the Mascot Racer genre.
• Super Smash Bros. is the Codifier of the Platform Fighter subgenre of fighting games.
• Team Fortress 2 did not invent the Hero Shooter (and almost isn't one itself), but every single game that was inspired by it, including Overwatch, Paladins, Battleborn, and Apex Legends, all feel its influence in innumerable ways in terms of creating unique, vibrant characters with specific roles to play in combat.
• For the 3D Fighting Game, Tekken is the most likely codifier, bringing together concepts introduced in preceding 3D fighters like Virtua Fighter (1993), Virtua Fighter 2, and Battle Arena Toshinden.
• Twisted Metal wasn't the first competitive Vehicular Combat game (both Battlesport and Cybersled predate it), but it certainly did popularize the genre and some features, such as tournament-based storylines, quirky characters and more differentiated vehicles.
• Unreal is the codifier for Secondary Fire, as every weapon in the game has an alternative firing option. This persisted through the entire Unreal series, including the Tournament games, and is now considered virtually mandatory in any FPS game.
• Warcraft:
  • Warcraft II, while not the first Real-Time Strategy game, was the first one to formalize the RPG aspects, including clearly visible hit point counters and Hero Units.
  • Tower Defense games were one of the major categories of user-made maps in StarCraft I, but the relatively primitive map editing tool and limited selection of combat-capable buildings meant that there was a far greater emphasis on mobile units. Warcraft III brought a more sophisticated editor which could be used to make custom buildings, and maps for that game codified the variety of towers, upgrade options, and lack of mobile attackers that are common in the genre today.
• During the Golden Age of the Western RPG, the codifier was Wizardry. The first-person, party-based Dungeon Crawler format became the standard format for computer RPGs. Ultima remained a major series, but largely did its own thing with its top-down maps and slightly greater focus on story (though it was extremely influential on the codifiers of the Eastern RPG, and on Bethesda and BioWare in later years).
• Worms codified the turn-based artillery gameplay of games like Gorillas and Artillery.

• Doki Doki Literature Club! is far from the first Disguised Horror Story, but it caused the trope to become a sub-genre of indie games, and also popularized the idea of fourth-wall shattering meta horror in indie games.
• Thanks to Fate/stay night's heroine Arturia Pendragon, a plethora of anime and video games now have blonde emotionally repressed Stoic Woobie ladies of war with dorky tendencies and a Dark and Troubled Past as either main characters or love interests.
• Higurashi: When They Cry, at least in Japanese media, probably codified secretly unstable characters.
• School Days is known for the Psychotic Love Triangle of Matoko Itou, Kotonoha Katsura and Sekai Saionji.
• Uta No Prince-sama helped form the general idea of fictional male Idol Singers in Japanese media, and especially the setup of putting them all in a music school to hone their skills.

• Animator vs. Animation was very popular for an inventive way to mixed animations with the software of the computer.
• Happy Tree Friends: Lumpy codified Moose Are Idiots.
• Kizuna Ai may not be the first "Virtual Vlogger" but she is responsible for coining and popularizing the concept of "Virtual YouTuber" that sprung up in the late 2010s, including the use of motion-capture and framing videos as a real person filming themselves (while obscuring the performer behind them), and the activities involved such as a combination of vlogging, Let's Plays, and singing. Her "A.I. living in Cyberspace" persona also led to many of her imitators making at least token gestures to being Ambiguously Human and/or Trapped in Another World.

• Darths & Droids is the codifier for the Campaign Comic. While preceded by DM of the Rings, a lot of traits that showed up later (such as players having backgrounds and personalities outside of the game) were established by it.
• The Order of the Stick, not only started, but codified using stick figures to tell stories set in an RPG Mechanics 'Verse. Much Follow the Leader has ensued. (See Stick-Figure Comic for the full list.)
• The Troll Face is the Codifier of the Memetic Troll, being the literal face of the trope.

• Galactic Puzzle Hunt was not only one of the first online puzzlehunt series but also paved a way for multiple online puzzlehunt series via gph-site, which was used by multiple other hunt franchises.
• LOLCats and their explosive popularity in the 2000s are the primary reason for the concept that The Internet Is for Cats.
• SCP Foundation codified the Artifact Collection Agency. Before its popularity the trope was far broader in both what kind of organisations existed, what they were collecting and why. Now, a rapidly growing majority of instances are nebulously supernatural organisations of unclear origin collecting unnatural items under the justification that they shouldn't exist, as well as more specific tropes like large amounts of redacted information, disposable minions for testing, and even the word "anomalous" or some synonym to describe what they're collecting.
• The Slender Man Mythos is the codifier for the Internet Myths and The Blank, with a very good reason.
• Wikipedia is an encyclopedia, and so influential that few wikis exist that aren't, functionally, specialized encyclopedias rather than, say, community projects or collections of cross-referenced essays. The most obvious counterexample, Everything Two, predates Wikipedia by three years.

• Most Analog Horror works draw influence from three major series:
  • ＬＯＣＡＬ５８:
    • Emergency broadcasts were already a part of the Analog Horror genre, thanks to earlier EAS Scenarios videos and No Through Road, but the series's first entry Weather Service started the trend of deceptive emergency broadcasts manipulated by hostile beings.
    • The titular television station inspired other mysterious television stations in future analog-horror works.
    • The Moon's presence as the series's main villain popularized cosmic horror for the genre.
  • Gemini Home Entertainment:
    • The first video WORLD'S WEIRDEST ANIMALS codified the Rule of Three format, beginning with two normal animals before focusing on a sinister third "animal", the Woodcrawlers. Said Woodcrawlers are also the first prominent Mimic Species for analog horror due to their ability to imitate human voices and spawn Fake People.
    • Most installments are peculiar educational videotapes, forming the groundwork for a certain analog-horror style.
  • Mandela Catalogue:
    • The Alternates in Volume 1 are the basis for humanoid entities in later analog-horror series, bonus points if they are shapeshifters with creepy smiles.
    • The series's villains are evil Biblical beings, introducing Religious Horror to the genre.
• While not the first Video Review Show, The Angry Video Game Nerd popularized the format.
  • And while the Nerd was the first character reviewer, The Nostalgia Critic was the first to go deeper, having multiple arcs on how being a Caustic Critic has ruined his life, unfolding an abusive backstory out during his run.
• Critical Role is the codifier for Actual Play web streams. Its popularity has led to the "Matthew Mercer Effect", wherein some new players of Dungeons & Dragons expect (1) that their Dungeon Master will run their game in a way similar to Mercer, (2) that their game will be as entertaining and fun, and (3) that if they stream their game it will also be as successful as Critical Role.
• Don't Hug Me I'm Scared and its television series both codified Disguised Horror Story and Surprisingly Creepy Moment respectively.
• Epic Rap Battles of History codified the rap battles using popular media characters.
• Game Theory codified the format of internet theories in video format for video games... and movies... and clothes... and food...
• Ryan ToysReview is not the first children's toy review channel (in fact, it's inspired by earlier ones, such as EvanTubeHD), but it ended up being the most famous and influencing later toy review channels.
• Yu-Gi-Oh! The Abridged Series is the unquestioned Trope Maker for The Abridged Series. But subsequent series have taken their cues from TeamFourStar and Dragon Ball Z Abridged.
• YouTube may not be the first video sharing-website but it most certainly did solidify the idea.

• The Animated Shock Comedy trope has the interesting siutation of having one Trope Codifier replaced with another. Initially, South Park primarily defined the genre as deliberately offensive and ugly. However, the wild success of Family Guy led to most mainstream examples of the genre going in a more cartoonish and surreal direction, with Family Guy-style adult animated comedies almost their own genre in modern streaming.
• Tex Avery, particularly in his short Red Hot Riding Hood, codified the Wild Take.
• Inspector Gadget codified the Inspector Oblivious.
• Looney Tunes:
  • Bugs Bunny codified Karmic Tricksters.
  • Wile E. Coyote and the Road Runner is the codifier for the Iron Butt-Monkey.
• Muppet Babies (1984) codified the Spin-Off Babies.
• Popeye's spinach is the codifier for Power-Up Food.
• The Powerpuff Girls (1998) codified Action Girl shows.
• The Ren & Stimpy Show codified the Gross-Up Close-Up and the Gross-Out Show.
• The Simpsons re-codified modern animated Sitcoms, with almost every example in the genre still being compared to the series. Bart Simpson himself also codified the Stock '90s Bad Boy.
• South Park codified the Subverted Kids' Show.
• While his original comic book counterpart is the codifier to Captain Fishman, the version of Aquaman from Superfriends is the reason why most examples of the trope are Joke Characters.
• Wallace & Gromit codified Silent Snarker. Seriously.

• Following the 2003 debut of a redesign for the $20 USD bill, people discovered that, by folding it a certain way, one can make the rear illustration resemble the World Trade Center on fire. The coincidence became a popular schoolyard parlor trick, and the fact that it was discovered concurrently with the rise of 9/11 conspiracy theories resulted in the Currency Conspiracy trope becoming a popular shorthand for nutty Conspiracy Theorist characters.
• While penalties for fouls and other infringements have been around for as long as sports have been around, the use of language neutral penalty cards, particularly yellow and red cards, was introduced in Association Football at the 1970 FIFA World Cup and has spread to other sports since.
• British actor Sean Bean is the Codifier for the Chronically Killed Actor. The majority of the roles Bean has taken over the years end in that character dying (and sometimes not in a pleasant way), and has inspired memes surrounding the trope that have his name on it.
• Charles II of Spain for Royally Screwed Up, the biggest reason ever given to breed outside the family once in a while. It's often remarked that the disorders from syphilis in the womb would have been among the few new genes in his bloodline.
• OpenAI's ChatGPT was not the first LLM (large language model), but it was the first one to become commercially available and gain widespread attention. Not long afterward, other LLMs (e.g. Anthropic's Claude, Google's Bard/Gemini, Meta's Llama, Mistral's Mixtral) also became commercially available.
• Geoffrey Chaucer is the Trope Codifier for the English language. He wasn't the first poet to write serious literature in English — there were several other major poets working in English at the same time — but he was by far the most influential. Between the Norman Conquest (at which point English was fairly unrecognizable to the modern eye) and Chaucer's day, most literature in England was written in Latin (if it was serious) or French (if it was meant for entertainment).
• Regarding computers in general:
  • As far as operating systems go, Acorn Computers' Arthur OS had the Ur-Example. NEXTSTEP had the original and the user-interface trope namer. But if you've got a dock in your operating system, the OS you're inevitably accused of copying is Apple's Mac OSX. So of course, it's also Older Than They Think.
  • For graphical interface conventions in general (mice, menus, windows, etc.), the Ur-Example was Xerox PARC's groundbreaking research of the '60s and '70s, which never turned into commercial products on their part, but was Xeroxed by Apple (the Trope Maker) as the basis for its Macintosh interface, and then ripped off (and made even more popular and mainstream) by Microsoft in Windows, the Trope Codifier.
• Clarence Darrow's defense of Leopold and Loeb was the codifier for Society Is to Blame.
  • Dan White's trial for the murder of Harvey Milk in 1978 (or rather, the media's complete and utter misunderstanding of what the Defense lawyers actually said) codified the use of the ridiculous excuse in murder cases (in this case, junk food).
• Digital Devil Story codified the Shin Megami Tensei metaseries, providing the original source material that eventually set the rules for all Mons Series.
• Fortune teller characters nowadays will likely take some influence from Miss Cleo. This results in Romani with Jamaican accents.
• For Virtual Idol Singers and the concept of an artificial singer in general, look no further than Hatsune Miku of Crypton Future Media, originating as the second of their Vocaloid Character Vocal series. While she has a predecessor in Sharon Apple of Macross Plus, her widespread popularity both in physical appearance and in voice make her one of the first thoughts people have regarding artificial celebrities.
• Stephen Hawking is one for Genius Cripple.
• The iPhone is not the first smartphone ever, but you'd be hard pressed to find a modern smartphone not influenced by it.
• The whole figure of Jesus Christ could be considered as a codifier of the Messiah, but Zeus from Greek mythology helped to cement the idea of a god being an old man with a beard sitting on a throne.
• Former Israeli prime minister Golda Meir is believed to be the first person to utter the "even a paranoid can have enemies" line so often used in reference to Properly Paranoid characters.
• Charles Ponzi was hardly the first to pull off a scheme of the type that would come to be known as a Ponzi scheme. (Defined as a scheme in which people pay in with the promise of huge returns, which eventually collapses, leaving people with little or nothing.) However the way he did it was so iconic that the scheme came to be known for him and named after him.
• The Trope Maker for the general-purpose programming language is Fortran (with the Turing Machine as the Ur-Example), but the Trope Codifier has to be C, to the point where modern languages not influenced by C in any way are a rarity.
  • For Object Oriented programming, the Trope Maker is Smalltalk, but it was codified by C++, and then further by Java. Funnily enough, according to Wikipedia an Ur-Example could be the cell. As in, the cell from biology. Seriously.
  • For modern, more weakly typed programming languages, Javascript and Python are the trope codifiers.
  • Visual programming languages, which rely on graphics more on text for programming, have existed in the '90s, examples being Etoys, Alice, and Max, but Scratch codified the genre, with its block-based programming as an influence on later, especially educational, ones.
• St. George and the Dragon codified the Dragonslayer figure. Even if Marduk made exactly that many centuries before.
• The Trickster God and, by extension, The Trickster, can largely be attributed to three deities: Anansi the Spider, Coyote the Trickster, and Loki the Lie-Smith.
• In one of the greatest upset victories in U.S. election history, the 1948 presidential election between Harry Truman and Thomas Dewey is the Codifier of the Assumed Win. The photo of Truman proudly holding up the newspaper reading "DEWEY DEFEATS TRUMAN" remains one of the most iconic images of his presidency.
• The underpinnings of modern French haute cuisine were laid by the likes of François Pierre La Varenne in the mid-to-late 17th century, and Antoine Carême in the early 19th century developed a style of cooking we recognize as the origin of our contemporary understanding of French gastronomy (particularly his emphasis on sauces and his classification of sauces by "mother sauce"). However, Carême's style was but one of several high-class cooking styles in France until the mid-to-late 19th century. It was the work of Auguste Escoffier in the late 19th and early 20th centuries which codified and streamlined Carême's ideas and became the reference point for all French cuisine after it.
• James Watt didn't invent the first stationary steam engine, and George and Robert Stephenson didn't invent the first steam locomotive. But their versions were so much more efficient than previous ones that they are often credited as the inventors.
• The United States is not the Ur-Example of The Federation, but it is the oldest extant example, with the Constitution providing the blueprint for the modern concept.
