->''"[[Creator/ArthurConanDoyle Conan Doyle]] did not invent the detective story - [[TropeMaker that honor]] goes to Creator/EdgarAllanPoe - but through his [[Franchise/SherlockHolmes immensely popular creation]], and his inventive series of tales, he was almost single-handedly responsible for creating a huge public interest in tales of mystery and detection."''
-->-- '''Cristopher and Barbara Roden''', introduction to Literature/SherlockHolmes

You have before you three series. The first, Series A, was the first known use of a trope, but it may or may not have been intentional. The second, Series B, was the first intentional use of the trope. The third, Series C, does not claim originality, and may in fact have ripped off series B, but was much more popular than Series A ''or'' B and is the template that all later uses of this trope follow.

Series A is the UrExample.

Series B is the [[TropeMakers Trope Maker]].

Series C is the [[TitleDrop Trope Codifier]].

In other words, if in tracing the history of a trope, one example stands out as the template that many, many other examples follow, that's the Trope Codifier.

The Trope Maker is frequently also the Trope Codifier, but not always. In particular, when the Trope Maker is a work of outstanding quality, the Trope Codifier may often be a story that shows how lesser authors can do a good imitation. Conversely, a great writer may gather up many old tropes and polish them to a shine, codifying them for later generations. Occasionally somebody rediscovers a ForgottenTrope.

The Trope Codifier may be [[TheThemeParkVersion the first theme park version]] or PragmaticAdaptation. If the trope is OlderThanTheyThink, the Codifier is usually ''mistaken'' for the Trope Maker. [[OlderThanDirt Really old tropes]] may have been codified every couple of centuries for millennia, as successive codifiers show how to adapt the age-old trope to their times. With the advent of television, a trope related to television may be codified by a new show every decade or two after the associations with previous codifiers have died out.

'''Important''': "Trope Codifier" does not mean SugarWiki/MostTriumphantExample. It means "Example that has fingerprints of influence on all later examples of the trope". The true marker of a Codifier is that it invents some unique spin on the trope that ''all'' later examples have some reaction to. Take, for example, Werewolves. There were earlier examples of werewolf stories, but it is with 1941's ''[[Film/TheWolfMan1941 The Wolf Man]]'' that we first see werewolves as an infection (previously, it was a curse or part of a DealWithTheDevil), silver vulnerability (previously, it was ''vampires'' or ghosts who were usually associated with weakness to silver), made the werewolf a human cursed to turn into a wolf-man (previously, all kinds of variations were available, from wolf that turns into a man, to man who [[BalefulPolymorph was permanently turned into a wolf]]), and tied the wolf to the night of the full moon (previously, they either focused on the three nights around the full moon, or had little to do with the phase of the moon). Almost all later examples of Werewolves bear some of these subtropes, which originated with ''The Wolf Man'', or at least [[DiscussedTrope discuss]] them in order to explain why OurWerewolvesAreDifferent. Thus, we can state with confidence that it is the Trope Codifier.
%% In other words, unless the trope is anime-specific, your anime example probably isn't the codifier.

Examples should be of Trope Codifiers that aren't Trope Makers themselves.

Related to OlderThanTheyThink. If a Trope Codifier is particularly influential, and the Trope Maker a little twisted you may have an UnbuiltTrope. Even the Trope Codifier itself may qualify as Unbuilt Trope because it tends to frequently contradict modern interpretations of said trope (and indeed most Trope Codifiers often have several major Unbuilt Tropes). There may also be a Series D which is the [[TropeNamers Trope Namer]], which is a series that uses the trope so commonly, so appropriately (or inappropriately, as the case may be), or so memorably,[[note]]Or so [[http://tvtropes.org/pmwiki/pmwiki.php/Main/Pun punnily]]; tropers can't resist a good pun[[/note]] that it provides a name for the trope.

[[folder: Anime & Manga]]
* ''Anime/NeonGenesisEvangelion'' is the Trope Codifier for DarkerAndEdgier, [[{{Deconstruction}} Deconstructed]] mecha anime with a metaphysical edge. ''Anime/GaoGaiGar'' and ''Anime/TengenToppaGurrenLagann'' attempted to [[{{Reconstruction}} Reconstruct]] the genre after it became overtaken by ''Eva''-inspired works.
** ''Evangelion'' can also be said to have taken the trope UpToEleven as it 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 AnimeFirst 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 marked.
* Speaking of ''Anime/TengenToppaGurrenLagann'', while the ''Manga/GetterRobo'' series introduced the ThisIsADrill trope to mecha fans, a lot of them will remember the former for taking the said trope as a massive plot point.
* While ''Manga/BlackLagoon'' introduced the ClusterFBomb and SirSwearsALot tropes in anime, ''Anime/PantyAndStockingWithGarterbelt'' has the most swearing out of any anime.
* ''Franchise/SailorMoon'' is frequently cited as the first user of the MagicalGirlWarrior subset of MagicalGirl shows. ''Anime/CuteyHoney'' used some of the tropes, but was usually seen as a straight-up SuperHero, especially since at the time "MagicalGirl" meant CuteWitch.
** The other codifer for the MagicalGirl genre in general is widely considered to be ''Manga/CardCaptorSakura''.
* ''Manga/RanmaOneHalf'''s Ranma Saotome and Akane Tendo aren't even Creator/RumikoTakahashi's first couple with BelligerentSexualTension. But they're the standard by which all others are measured.
** Ranma is also the most likely codifier for MartialArtsAndCrafts 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 NoSenseOfDirection. His sense of direction is so bad that he literally traverses across continents and oceans without even realizing it.
* ''Manga/LoveHina'' essentially defined the turn-of-the-millennium style of {{Unwanted Harem}}s.
* ''Manga/FullmetalAlchemist'' popularized the concept of EquivalentExchange and MagicAIsMagicA, at least for anime and manga.
* If ''Manga/FistOfTheNorthStar'' is the Trope Maker for the shonen FightingSeries, then ''Manga/DragonBall'' and ''Anime/DragonBallZ'' are the codifiers.
** Speaking of ''Manga/FistOfTheNorthStar'', it can be considered the codifier for the YouAreAlreadyDead and RapidFireFisticuffs 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.
* While there had been examples and uses of CyberPunk tropes in other series such as ''Manga/{{Appleseed}}'', ''Franchise/GhostInTheShell'' is seen as codifying CyberPunk themes into anime such as [[RidiculouslyHumanRobots cyborgs]], TheMetaverse, and other such themes.
* ''Manga/{{Akira}}'' was the TC for anime as a whole in the US and UK - a 'cartoon' that was dark, grim, violent, bloody, beautiful and not a little {{mind screw}}y. As a consequence, it burrowed into the collective subconscious and created a new image that took years more to shake off.
* ''Anime/MobileSuitGundamWing'' jump-started the trend of HumongousMecha series having {{Bishonen}} protagonists to give it a PeripheryDemographic of young females.
* ''Manga/AzumangaDaioh'' is the eternal Trope Codifier of the SchoolgirlSeries and associated tropes, including WackyHomeroom and SenseiChan.
* ''Manga/RurouniKenshin'', the titular character is the codifier for XMarksTheHero.
* While mostly unknown in English speaking countries until ''Manga/ThePrinceOfTennis'', 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 TheSixties, ''Kyojin No Hoshi'' started the ''supokon'' ([[HotBlooded sports & guts]]) genre, putting the focus on the [[TrainingFromHell grueling training and sacrifice]] in the [[SeriousBusiness dogged pursuit of the top]]. It is the closest thing to a codifier for all sports anime and manga, and especially baseball. ''Manga/TigerMask'' and ''Manga/AshitaNoJoe'' similarly codified wrestling and boxing series, respectively.
** ''AttackNumberOne'' codified {{Shoujo}} sports series as well as volleyball manga with hotblooded grace, with ''Manga/AimForTheAce'' doing the same for tennis during TheSeventies.
** TheEighties saw the arrival of arguably the single most popular sports manga and anime, ''Manga/CaptainTsubasa''. While occasionally violent for drama, it was a much more [[SlidingScaleOfIdealismVersusCynicism bright-eyed]], [[RuleOfCool 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 the focus on [[RuleOfFun 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 TheNineties, Manga/SlamDunk became extremely popular despite keeping everything down to earth. Rather than being about [[BeyondTheImpossible larger than life]] [[InstantExpert geniuses]], it balanced daily life, comedy, and relationships. The series codified basketball manga and how to [[{{Realism}} realistically]] approach a sports series while keeping audiences hooked.
* While it certainly existed earlier, ''Anime/MagicalGirlLyricalNanoha'' codified the DarkMagicalGirl trope for anime with the character of Fate Testarossa.
* Yuno Gasai from ''Manga/FutureDiary'' is essentially the codifier for the {{Yandere}} trope. While she had [[OlderThanDirt predecessors]] for this trope before her introduction, her character practically defined the trope inits current form, becoming both types throughout the story.
* ''LightNovel/ShakuganNoShana'' and ''LightNovel/TheFamiliarOfZero'' popularized the {{Tsundere}} stereotype. While ''Evangelion'' had already introduced one of the most popular tsunderes in anime, ''Shana'' popularized the concept of the ShanaClone, and ''Familiar'' was the one of the first works to use it.
* ''LightNovel/{{Baccano}}'' popularized the CastFullOfCrazy trope, with everyone (across three storylines, no less) being [[BrokenBird horribly broken]], [[AxCrazy downright unhinged]], or [[{{Cloudcuckoolander}} just plain nuts]].
* ''YuGiOh'' is the reason we have AnimeHair.
* Yuuki Rito of ''Manga/ToLoveRu'' was certainly not the first harem series protagonist to have a SuggestiveCollision or ThanksForTheMammary 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.

[[folder: Comic Books]]
* Franchise/{{Superman}} is the Trope Codifier of {{superhero}}es in general, and also for the FlyingBrick kind of superhero.
* ComicBook/{{Watchmen}} and Comicbook/BatmanTheDarkKnightReturns are co-codifiers of DarkerAndEdgier.
* Franchise/{{Batman}} is the Trope Codifier of the BadassNormal superheroes and TheCowl.
* SelfDemonstrating/TheJoker is the Trope Codifier for {{Monster Clown}}s. (It was Pennywise from Creator/StephenKing's ''Literature/{{It}}'' who truly took the trope mainstream, though.)
* ComicBook/{{Catwoman}} was the first really popular female antihero.
* Franchise/SpiderMan is often credited as being the Trope Codifier for both the non sidekick KidHero and WakeUpGoToSchoolSaveTheWorld. Also to BuildingSwing, Since almost every time you see it anywhere else, it is a reference, or [[LampshadeHanging Lampshaded]] by a character.
** His main love interest, Mary Jane Watson, would be the codifier for HeroesWantRedheads.
* Jay Garrick, the first [[Franchise/TheFlash Flash]] is the Trope Codifier for the specialized single super power superhero.
* Comicbook/{{Robin}} is the codifier for KidSidekick.
* ComicBook/ThePunisher is the Trope Codifier of the SociopathicHero. He was, by far, the most popular costumed "superhero" to kill his enemies rather than putting them to jail. And he's been doing it way before the [[UsefulNotes/TheDarkAgeOfComicBooks Dark Age of Comics]].
* John Constantine, ''ComicBook/{{Hellblazer}}'' is the Trope Codifier of characters being ExiledFromContinuity and DidYouJustScamCthulhu.
* Although he wasn't the first, {{Deadpool}} by far is the most well-known character who [[BreakingTheFourthWall breaks the fourth wall]]. Virtually every media about him from comics to memes lack the aforementioned wall (and he knows it).
* Franchise/WonderWoman is the Codifier for female superheroes.
* Comicbook/{{Supergirl}} is the Trope Codifier of DistaffCounterpart characters, having all Superman's powers.

* Typically, gangster films borrow from one of two cookie sheets: ''{{Film/Goodfellas}}'' (for black comedies) or ''Film/TheGodfather'' (operatic tragedies).
-->'''Website/TheAgonyBooth''': Brando gives his best performance, a legendary bit of acting thatís 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. Iím not sure whatís kept this from happening, but Iím fairly sure itís connected to the Cubs not making it to the World Series. Sorry Chicago, but I think [[RealityBreakingParadox the safety of our universeís existence]] may depend on your baseball team stinking like death for the rest of eternity.
* ''Film/{{Halloween 1978}}'' was the Trope Maker for the Slasher genre, but ''Film/FridayThe13th1980'' was the Trope Codifier. In particular, ''Film/FridayThe13th1980'' was the actual Trope Maker for DeathBySex rather than Death By Not Paying Attention (Including Having Sex) for all the imitators that followed.
** Arguably, the Italian proto-slasher ''{{giallo}}'' film ''Film/ReazioneACatena'' was the trope codifier for ''Film/FridayThe13th1980'' itself (and, by extension, slasher movies with its derivative formula), featuring the aforementioned DeathBySex trope; a [[DontGoInTheWoods seemingly desolate forest setting]] (on an idyllic waterfront, no less); an [[KillEmAll exceedingly high body count]]; and an all-around liberal employment of {{Gorn}}. Indeed, both ''Friday the 13th'' and [[Film/FridayThe13thPart2 its first sequel]] directly recreated certain scenes from ''Reazione a Catena'' (including [[spoiler:spearing a copulating couple to death ''twice'' and embedding a sharp instrument in a respective victim's face]]). Earlier ''gialli'' (and American slasher antecedents such as ''Film/{{Psycho}}'') also employed certain variations of these tropes, but not in formulaic tandem with one another.
* ''Franchise/StarWars'':
** is the Trope Codifier for Joseph Campbell's [[TheHerosJourney 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 ''Franchise/StarWars'' - and any ''bad'' story that follows the Hero's Journey pattern actually ''does''.
** ''Franchise/StarWars'' (along with ''Film/BladeRunner'') was also instrumental in making the UsedFuture concept widespread.
** The OldSchoolDogfight was popularized by the films' use of it as an {{homage}} to UsefulNotes/WorldWarII air war films, with the Death Star trench run in ''Film/ANewHope'' in particular inspired by ''Film/TheDamBusters''.
* ''Film/BladeRunner'' 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 ''Film/MadMax'' franchise is the most well-known example of the [[AfterTheEnd 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 [[ScavengerWorld scrappy resources]], to crazy [[TheApunkalypse punk fashions]], to the mad and totalitarian society; every apocalyptic film after that had a pint of influence that came from the series.
* ''Film/TheMask'' is the most famous example of HeartBeatsOutOfChest, while Creator/TexAvery was the TropeMaker.
* ''Franchise/{{Godzilla}}'' is the most well-known {{Kaiju}}, and of monster movies in general together with Film/KingKong.
* ''Film/{{Rocky}}'' is the most well-known sports film that introduced the [[UnderdogsNeverLose underdog]] archetype to the modern viewers.
* ''Film/{{Batman}}'' 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 SummerBlockbuster: changed it "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".
* [[Film/{{Dracula 1931}} The 1931 movie version]] of ''Literature/{{Dracula}}'' codified most modern VampireTropes.
** And the Trope Codifier for OurVampiresAreDifferent would be ''Film/{{Nosferatu}}'', which was where vampires being weak to sunlight originated from.
* The 1941 film ''[[Film/TheWolfMan1941 The Wolf Man]]'' codified the tropes for [[WolfMan werewolves]], as well as being the UrExample 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.
* ''Film/{{The Birth of a Nation|1915}}'' 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.
** ''Film/TriumphOfTheWill'' 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.
* ''Film/ThisIsSpinalTap'': The Codifier for the feature film {{Mockumentary}} genre. The Trope Maker is probably Creator/WoodyAllen's ''Film/{{Zelig}}'', released just one year before (1983). The older example, Music/TheRutles' ''All You Need Is Cash'' (1978), was a television film.
* ''Film/TheBlairWitchProject'' is the trope codifier for the [[FoundFootageFilms found footage]] mockumentary horror films of the 2000s. The trope maker is ''Film/CannibalHolocaust''.
* 1972's ''Film/ThePoseidonAdventure'' pretty much established the template for future [[DisasterMovie disaster movies]], despite sharing many elements with earlier entries of the genre like ''Film/ANightToRemember''.
* TimeTravel: the UrExample is hard to identify, the TropeMaker is ''Literature/TheTimeMachine'' by Creator/HGWells, the TropeCodifier is ''Film/BackToTheFuture''.
* The ''Film/CreatureFromTheBlackLagoon'' wasn't the first FishPerson, but he's certainly the best-known and most influential example.
* There were car chases on film before, but the one in ''Film/{{Bullitt}}'' became the most famous one which all films after tried to emulate.
* ''Film/BlackHawkDown'' is the first major movie that popularized modern, 21st century (although the movie actually takes place in 90s, the principle is intact) warfare. This movie is majorly responsible for the games like ''VideoGame/ModernWarfare'', ''VideoGame/MetalGearSolid4'', and ''VideoGame/ResidentEvil5''.
* The HollywoodNuns trope owes itself largely to three films. ''Film/TheSongOfBernadette'' (1943) was the initial Trope Codifier, and ''Film/TheNunsStory'' (1959) and ''Theatre/TheSoundOfMusic'' (1965) solidly reinforced the trope. Because they were so popular, they were used as templates for nuns in film forever after.
* For PieInTheFace, the massive pie fight in the Creator/LaurelAndHardy silent short ''[[https://www.youtube.com/watch?v=qlIXByXcUHw The Battle of the Century.]]''
* ''Film/RebelWithoutACause'' and ''Film/AmericanGraffiti'' made the teen movie a popular and profitable genre with its use of teenage {{wangst}} and [[WildTeenParty parties]], that teenagers around the world loved and related to. However, films such as ''Film/MeanGirls'' and ''Film/AmericanPie'' 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.
* Examples of GigglingVillain go at least as far back as Creator/ArthurConanDoyle and Literature/SherlockHolmes, but the Trope Codifier is deeply deranged giggling psychopath Tommy Udo in ''Film/KissOfDeath''. Richard Widmark's performance became iconic influenced, among other things, the portrayal of The Joker in various Franchise/{{Batman}} adaptations.
* The Film/CarryOn franchise confided AffectionateParody 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.[[/note]] However, the movies were the TropeMaker of AwfulBritishSexComedy (the confiders were ''Film/ConfessionsOfA'' series) due to the use of explicit nudity [[GettingCrapPastTheRadar 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 [[FanonDiscontinuity one of the worst in the series]].
* While SteamPunk existed before the 1998 film ''Film/WildWildWest'', the movie brought it into the mainstream for the first time, combining Victorian aesthetics with pre-electric machinery. Most Steam Punk fans don't ''like'' admitting that the genre owes so much to a 90's Creator/WillSmith movie, but its visual effects were widely praised as the film's sole redeeming feature, and its influence can be seen in Steam Punk works to this day.
* ''Film/MrVampire'' 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.
* ''[[LethalWeapon Lethal Weapon 2]]'' Laid out the blueprint for criminals invoking DiplomaticImmunity to commit crimes without the slightest fear of reciprocity.
* ''Franchise/{{Lassie}}'' is the codifier for the HeroicPetStory. While not the first {{Action Pet}}, she is the most iconic and helped kickstart the genre.

* The StandardFantasySetting's Trope Maker was ''Literature/TheLordOfTheRings''; the Trope Codifier was ''TabletopGame/DungeonsAndDragons''.[[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 certain aspects of the StandardFantasySetting, but didn't seem to qualify for full Trope Maker status.[[/note]]
** Except for VancianMagic, which [[TropeMakers was made by]] ''Literature/DyingEarth'' and codified by ''D&D''.
*** ''D&D'' can also be seen as the Trope Maker of Fantastic Miniatures War Games (Chainmail was the UrExample of a Mini's games featuring fantastic elements, and D&D was originally just the "small warbands" variant of it), but TabletopGame/{{Warhammer}} and TabletopGame/{{Warhammer 40000}} are the Trope Codifiers.
** Another Trope Codifier was Terry Books's novel ''The Sword of Literature/{{Shannara}}'', which showed that {{Doorstopper}} fantasy novels that weren't written by Tolkien could also go on to sell zillions of copies.
* ''Literature/SherlockHolmes'' is the Trope Codifier for many detective tropes; Creator/EdgarAllanPoe's ''Literature/CAugusteDupin'' stories were the Trope Maker, including such tropes as the less astute [[TheWatson Watson figure as narrator]] and the far-reaching deductions based on attention to seemingly trivial details.
** A second possibility, wildly popular at the time but now more obscure, is ''Literature/TheMoonstone'' by Wilkie Collins. It placed such concepts as the private detective helping out the near useless police and the LockedRoomMystery into the popular consciousness a few decades before Doyle's novels.
* ''Franchise/{{James Bond}}'' is the most popular image of {{Spy Fiction}}. Virtually every fictional spies in history has its roots from the Bond character.
* ''Theatre/{{Medea}}'' is the Trope Codifier for the WomanScorned, although Ishtar from ''Literature/TheEpicOfGilgamesh'' is the [[UrExample oldest known example]].
* Creator/RaymondChandler is considered the Trope Codifier of [[HardboiledDetective hard-boiled crime fiction]], following Carroll John Daly with the Ur-example (his "Knights Of the Open Palm" was published several months before Hammett's first ''[[Literature/TheContinentalOp Continental Op]]'' story) and Creator/DashiellHammett (the Trope Maker).
* The earliest use of AncientAstronauts is ''Edison's Conquest of Mars'' from 1898, but the first popular story to use the concept was ''Literature/AtTheMountainsOfMadness'' from 1931.
* ''The Red Badge of Courage'' did this for WarIsHell.
* ''Literature/TheCountOfMonteCristo'' is one for the "return for elaborate revenge story".
* While ''Literature/{{Dracula}}'' was the first modern codifier for [[OurVampiresAreDifferent vampiric tropes]], ''Literature/TheVampireChronicles'' by Creator/AnneRice was a [[SubvertedTrope subversion]] that served to codify the current template used by everyone from [[TabletopGame/VampireTheRequiem White Wolf]] to ''Literature/{{Twilight}}'' and ''Film/{{Underworld}}''. [[UndeadHorseTrope Both kinds of vampire are in active use, of course.]]
** With an exception: for easily understood reasons, most successors have thrown out Creator/AnneRice's vision of vampires as lacking sufficient bloodflow to get it up.
* Contrary to [[OlderThanTheyThink what some fans believe]], ''Literature/HarryPotter'' didn't originate the WizardingSchool trope - but it is such a prominent codifying example that everything that comes after (and some things that came before) will have to either FollowTheLeader or strenuously differentiate itself from Hogwarts.
** The Wizarding World may very well be the codifier of the MagicalSociety.
* ''Literature/SnowCrash'' is widely recognized as the codifier for TheMetaverse and the DigitalAvatar but Creator/WilliamGibson did them first.
* Jonathan Swift's ''Literature/AModestProposal'' is regarded as the codifier of the StealthParody.
* Creator/RobertEHoward's ''Literature/ConanTheBarbarian'' codified the BarbarianHero - and many other SwordAndSorcery tropes, at least among those he wasn't the Trope Maker for it.
* There have been intelligent and malicious weapons before, but Stormbringer from Moorcock's ''Literature/TheElricSaga'' is the codifier for EvilWeapon (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.
* ''Literature/{{Twilight}}'' is the codifier of the ''mainstream'' ParanormalRomance genre.
* ''Literature/{{We}}'' is the trope maker for dystopic fiction, but ''Literature/BraveNewWorld'' and ''Literature/NineteenEightyFour'' are the codifiers.
* ''Literature/ForWantOfANail'' is an AlternateHistory textbook that explores two hundred years of counterfactual events following a [[PointOfDivergence failed American Revolution]]. It serves as codifier for the genre, more specifically, the type common to Website/AlternateHistoryDotCom, which often features narratives presented like a non-fiction description of actual events.
* ''Literature/ThePhantomOfTheOpera'' is a major TropeCodifier for supervillains.
* Peter Rabbit along with his sisters Mopsy, Flopsy, and Cottontail from ''Literature/TheTaleOfPeterRabbit'' serve as the codifier for the earliest use of bunnies seen eating a carrot which has become a [[StockAnimalDiet major stereotype for bunnies in general]]. The rabbit characters could also be one of the earliest uses of [[BunniesForCuteness rabbits seen in media that are portrayed as cute and adorable looking]] which wasn't a common trope for bunnies back when the original story was made in 1901. But would later become one of the more well-known tropes associated for rabbits besides the RascallyRabbit Trope which had also been made popular by Bugs Bunny.
* ''Literature/WatershipDown'' and ''Literature/WarriorCats'' are this to the StrayAnimalStory 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.

[[folder: Live Action TV]]
* In {{Reverse Whodunnit}}s, the Trope Codifier is ''Series/{{Columbo}}'', Trope Maker being R. Austin Freeman's ''Literature/DrThorndyke''.
* Despite the name, DawsonCasting was neither made nor codified by ''Series/DawsonsCreek''; ''Series/BeverlyHills90210'' does the codifying honors there. Possible Trope Makers include ''Theatre/ByeByeBirdie'', 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 TeenDrama; it borrowed heavily from ''Series/DegrassiJuniorHigh'' and, besides adding the too-old "kids" moved the setting from a nondescript part of UsefulNotes/{{Toronto}} to one of the [[SlidingScaleOfShinyVersusGritty shiniest]] places the writers could think of. Two things most teen dramas since have kept in the mix.
* ''Franchise/StarTrek'' 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 ''Series/{{Heroes}}''.
** ''Series/StarTrekTheOriginalSeries'' did codify the RedShirt, 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 DirtyOldMan meant the sexually-explicit stuff didn't bother him), meaning it was a relatively safe haven for pre-Internet fandom.
* The ''Franchise/KamenRider'' franchise, while not the first HenshinHero example (that would likely go to the ''Franchise/UltraSeries''), is the go-to standard for HenshinHero.
** ''Series/KamenRiderRyuki'' pretty much becoming the TropeCodifier for all of the following Kamen Rider shows, with current series staples such as collectible devices, TransformationTrinket that has to be carried everytime, and AntiHero or pure evil Riders all making their debuts in Ryuki.
* The first usage of {{Sentai}} doesn't come from ''Franchise/SuperSentai'', but UsefulNotes/KatanasOfTheRisingSun of UsefulNotes/ImperialJapan during UsefulNotes/WorldWarII. The term "Sentai" was relegated after the war, but ''Super Sentai'' codified this term for the squadrons with ColorCodedCharacters.
* Mork from ''Series/MorkAndMindy'' is the most prominent example of an AmusingAlien.
* ''Series/IronChef'' is the Trope Codifier for the CookingDuel trope.
* ''Series/MalcolmInTheMiddle'' is the trope codifier for the single camera, on-location, LaughTrack-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 ''Series/TheAdventuresOfPeteAndPete'' and ''Series/TheLarrySandersShow'', 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, ''Series/{{Spaced}}'' did the same thing for British sitcoms.
* ''Series/EverybodyLovesRaymond'' was hugely influential to later sitcoms and is a codifier for AllWomenArePrudes 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 ''Series/HomeImprovement'', where wife Jill was a self-admitted feminist and Tim was the one who screwed up 99.5% of the time.
* ''Series/SavedByTheBell'' is the Trope Codifier for the SixStudentClique.
* ''Series/TheRealWorld'' is the Trope Codifier for {{Reality Show}}s.
** Likewise, the hit series ''Series/TheBachelor'' codified the romance for {{Reality Show}}s.
* ''Series/{{V 1983}}'' is the Trope Codifier for OminousFloatingSpaceship and TheReptilians.
* Lionel Luthor from ''Series/{{Smallville}}'' is the Trope Codifier for MagnificentBastard. The phrase itself comes from the 1970 movie ''Film/{{Patton}}'', and was used extensively by Website/TelevisionWithoutPity's recaps of ''Smallville'', to describe Lionel and the prodigious wheeling and dealing he engaged in throughout the course of the series.
* ''Series/KamenRiderRyuki'' is the trope codifier for [[ThereCanOnlyBeOne Battle Royale-esque]] fiction in Japanese media.
* ''Series/{{Cheers}}'' and BelligerentSexualTension. Sam and Diane provided the template for sitcoms to follow. Ditto for the WillTheyOrWontThey romantic storyline.
* ''Series/{{Oobi}}'' for BareHandedPuppetry. Parodies and homages to the bare-hand puppets on ''Oobi'' are just as common as unrelated uses of this trope, if not more so.
* ''Series/AmericanIdol'' would very well be the Codifier for TalentShow (''Series/StarSearch'' 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 FunnyMoments.
* The ''Series AddamsFamily'' for CreepyGood. May be the maker as well. They're creepy and spooky and altogether ooky but generally loving and benevolent.
* ''Series/DoctorWho'': It is the Trope Codifier for ReversePolarity, with many other shows using it as a ShoutOut to the franchise.

* Music/TheBeatles were the codifiers for UsefulNotes/TheBritishInvasion, the modern rock band lineup and writing conventions, and, with Music/SgtPeppersLonelyHeartsClubBand, modern recording techniques such as layered, multi-track production.
* By the time of Music/MichaelJackson, {{music video}}s were evolving beyond just shots of the band, but he set the standard for everything that came after him.
* Music/TupacShakur and Music/TheNotoriousBIG are the joint codifiers for GangstaRap.
* If Music/LedZeppelin was the UrExample of HeavyMetal, and Music/BlackSabbath was the Trope Maker, Music/JudasPriest 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. Music/{{Motorhead}} also helped in the codifying of metal. They took influence from PunkRock and from HeavyMetal and, in turn, inspired much of ThrashMetal.
** 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.
** Music/{{Metallica}}, Music/{{Slayer}}, and Music/ExodusBand are the codifiers for American ThrashMetal, with the vast majority of thrash bands modelling themselves on one of the three. In Germany, the codifiers are Music/{{Kreator}}, Music/{{Sodom}}, and Music/{{Destruction}} (collectively known as the Three Teutonic Kings of Thrash Metal), and in Brazil, the codifiers are Music/{{Sepultura}}, Sarcófago, and Vulcano.
** In the public eye, Music/CannibalCorpse is generally held responsible for popularizing DeathMetal outside the metal underground, but Music/{{Deicide}}, Music/MorbidAngel, and Music/{{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 Music/{{Entombed}} or Music/{{Dismember}}.
*** For TechnicalDeathMetal, the codifiers are Music/{{Atheist}}, Music/{{Death}}, and Music/{{Necrophagist}} for "straight" tech, Music/{{Cynic}}, Music/EdgeOfSanity and Music/{{Opeth}} for prog-tech, Music/{{Suffocation}} and Music/{{Origin}} for brutal tech, and Music/{{Gorguts}} for experimental tech.
*** {{Melodic Death Metal}}'s major codifiers are Music/AtTheGates, Music/InFlames, and Music/DarkTranquillity for the genre as a whole, Music/ChildrenOfBodom for PowerMetal[=/=]Neoclassical Metal-inspired melodeath, Music/{{Soilwork}} for {{Alternative Metal}}-tinged forms, Music/{{Ensiferum}} for {{Folk Metal}}-melodeath fusions, and Music/{{Wintersun}} for [[SymphonicMetal symphonic]] melodeath.
** Music/{{Mayhem}}, Music/{{Burzum}}, Music/{{Darkthrone}}, Music/{{Immortal}}, and Music/{{Emperor}} are the collective Trope Codifiers for BlackMetal, particularly the Second Wave. For the First Wave, the codifiers are generally agreed to be Music/{{Bathory}}, Hellhammer, and Music/CelticFrost.
*** For Viking Metal, the codifiers are Music/{{Enslaved}} and Graveland.
*** Music/{{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 BlackMetal 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 PowerMetal tends to vary depending on the region, with Music/{{Helloween}} and Music/{{Stratovarius}} being the European scene's codifiers, Music/{{Manowar}}, Music/JagPanzer, and Manilla Road being the American scene's codifiers, Music/XJapan being the Japanese scene's codifier, and Music/{{Angra}} being the Brazilian scene's codifier.
** Though the genre has existed since the TheSeventies in the form of bands such as Music/BlackSabbath, Music/{{Pentagram}}, and The Obsessed, the main codifiers for DoomMetal are generally considered to be Music/{{Candlemass}}, Saint Vitus, Trouble, and Music/{{Cathedral}}.
*** For Death[=/=]Doom Metal, the codifiers are early Music/MyDyingBride, Music/{{Katatonia}} and Music/ParadiseLost.
*** While Stoner Metal existed before Music/ElectricWizard, 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 Music/{{Crowbar}} and Music/{{Eyehategod}}.
*** Music/{{Isis}} is considered to have codified Post Metal, with Neurosis being the TropeMaker and Music/{{Godflesh}} being the UrExample.
** Music/NineInchNails, Music/FearFactory, Music/{{Rammstein}}, and Music/MarilynManson are all pretty much equally responsible for popularizing IndustrialMetal, 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 SopranoAndGravel 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 GrooveMetal, MelodicDeathMetal, and {{Metalcore}} bands since.
** Music/DreamTheater may not have been the first ProgressiveMetal band, but ''Images and Words'' is the album that defined the style and what the entire genre is built upon.
** While Music/{{Pantera}}'s status as {{Groove Metal}}'s TropeMaker 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 TropeMaker of AvantGardeMetal was probably either Music/CelticFrost, Music/{{Voivod}}, or Music/{{Atheist}}, while Music/MrBungle or Music/{{Korn}} are sometimes considered TropeMaker for experimental. Music/{{Therion}} is generally considered to have codified avant-garde metal while Music/EnterShikari codified modern avant-garde. Music/FaithNoMore are considered trope codifier for experimental metal, Music/{{Meshuggah}} for {{djent}}y experimental (as well as being TropeMaker for djent), and Music/SystemOfADown for modern experimental. The eastern scene has its own codifiers, Music/DirEnGrey, Music/{{Sigh}}, Music/SoundHorizon, and Music/FearAndLoathingInLasVegas.
* In the PunkRock genre, Music/TheRamones is considered to be the TropeMakers. 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 Music/SexPistols and Music/TheClash 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 TropeCodifier of ThreeChordsAndTheTruth. These UK bands were the ones who invented [[https://en.wikipedia.org/wiki/Punk_ideologies punk ideology]].
** The Sex Pistols' songs such as ''[[https://www.youtube.com/watch?v=q31WY0Aobro Anarchy in the UK]]'' and ''[[https://www.youtube.com/watch?v=yqrAPOZxgzU God Save The Queen]]'' are considered to be the first modern punk rock songs.
** For the HardcorePunk subgenre, the codifiers are considered to be Music/BlackFlag, Music/BadBrains, and Music/MinorThreat for the Eastern United States and Music/DeadKennedys for the Western United States.
** For PostPunk, the codifier (and TropeMaker) is Music/JoyDivision
*** Music/{{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 The Offspring and Green Day (with some also crediting blink-182 with creating the sound that early to mid 2000's pop-punk bands would be influenced by.) The concept of combining fast, aggressive music with pop lyrics, however, was invented much earlier by bands like The Buzzcocks and The Undertones.
* 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.
* Music/RichardWagner coined the term "{{leitmotif}}" in an 1851 essay and codified the concept in his famous cycle ''Theatre/DerRingDesNibelungen,'' 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.
* Using Auto-Tune for a robotic effect didn't become prominent until the arrival of Music/TPain 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.
* If this trope is possible on one network, then Music/HilaryDuff is the trope codifier for the current batch of teenage {{Idol Singer}}s on Creator/DisneyChannel. 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.
* Despite Music/BuckTick and Music/XJapan being prominent early examples, Music/{{Kuroyume}} set the template for nearly every VisualKei band that followed, including better known (at least in the West) examples such as Music/DirEnGrey and Music/LunaSea.
* While Music/ToddEdwards 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 [[Creator/NickBertke Pogo]] and Music/{{Skrillex}}.
* Dizzee Rascal's debut album, ''Boy in da Corner'', popularized grime, a fusion genre mixing rap with electronic music.
* 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.
* Music/LLCoolJ's "I Need Love" is considered the first rap ballad (though the UrExample 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 OneHitWonder-y rapper will release at least one slow love song.
* Music/SkinnyPuppy was the codifier for {{Industrial}} Music's current, electronica-influenced sound; before them, {{Industrial}} tended to be a [[UnbuiltTrope dark, dissonant, and experimental affair]].
* Music/TinaTurner is the trope codifier for female diva singers with over the top wardrobes. She specifically has influenced female African-American singer such as Music/{{Beyonce}}.
* With IndiePop rising to popularity in TheNewTens, Music/{{Lorde}} quickly became the codifier for the genre. Not only for "Royals", one of the biggest indie pop hits ever, but also for ''Music/PureHeroine'', which is quite possibly the most successful indie pop album of the decade. ''Billboard'' even named her the "Queen of Alternative".
* Music/PinkFloyd is the TropeCodifier for the usage of BookEnds in music, incorporating it on many of their albums (''Music/TheDarkSideOfTheMoon'' has a HeartbeatSoundtrack, ''Music/{{Animals}}'' and ''Music/WishYouWereHere'' have one song split into the opening and ending tracks, ''Music/TheWall''[='=]s ending segues into the opening).
* Music/JanetJackson 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 Music/BritneySpears, to Music/{{Usher}}, to Music/{{NSYNC}}, to Music/{{Beyonce}}, to Music/LadyGaga.
* Music/{{Kraftwerk}} is the TropeMaker of ElectronicMusic, and Music/AphexTwin is the TropeCodifier with his seminal ''Selected Ambient Works 85-92'' album.
* {{Vaporwave}} has two. For first-wave vaporwave (2011-2013), Music/{{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 '''''Magazine/RollingStone'''''.
* Music/EmersonLakeAndPalmer are almost certainly the codifiers for RockMeAmadeus; they used it far, far more than anyone else had before them and brought classical works like ''Music/PicturesAtAnExhibition'' 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.
* Granted 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 [[TropeNamer name to the genre]] Plunderphonics and also its very identity with his album Plunderphonics.

[[folder:Newspaper Comics]]
* ''ComicStrip/{{Garfield}}'' is easily the codifier for HatingOnMonday.
* ''ComicStrip/TheFarSide'' was far from being the first single-panel comic strip, but it made the format popular again in the 1980s.

[[folder:Professional Wrestling]]
* Wrestling/SuperstarBillyGraham created the "flamboyant bodybuilder" wrestler archetype as we understand it today, directly inspiring Hulk Hogan - and, also, probably serving as wrestling's TropeMaker for RealMenWearPink. (Wrestling/BuddyRogers and Wrestling/RicFlair also had blond hair and tanned skin, but they didn't really have the muscles.)
* The Lucha Libre Internacional match in 1977 featuring Huracan Ramirez and Black Shadow teaming up with Wrestling/ElSanto 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.
* Wrestling/HulkHogan is arguably the codifier for the AllAmericanFace, given that his name has practically become synonymous with the archetype.
* Wrestling/BigVanVader and Wrestling/TheUndertaker are the trope codifiers for the WrestlingMonster, drawing on the earlier "wild-man" characters of Wild Red Berry, Wrestling/GorillaMonsoon, and [[Wrestling/GeorgeSteele George "The Animal" Steele]] (themselves swiping the gimmick from carnival sideshows) adding in an elaborate {{back story}} in the case of Vader (written by the famed Go Nagi no less!) and some truly impressive special effects in Taker's case([[SpecialEffectsFailure but not always]])
* Wrestling/{{All Japan|ProWrestling}} co founder Akio Saito popularized the sit down power bomb in the United States, which would later be taken up by the likes of Wrestling/DLoBrown(a running variant) and Wrestling/{{Batista}}.
* Wrestling/{{CMLL}}'s mini estrellas were the trope makers for having the same [[TheGimmick gimmick]] on multiple luchadors of different sizes, most notably Mascara and Mascarita Sagrada, but Wrestling/{{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.
* Wrestling/{{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.
* Wrestling/StacyKeibler was WWE's codifier for CuteBruiser (Wrestling/TerriRunnels being the TropeMaker and [[Wrestling/TammyLynnSytch Tammy Lynn "Sunny" Sytch]] being the UrExample).

* The TropeCodifier for combining the BrainlessBeauty and DumbBlonde tropes into one character might have been the enormously popular late 1940's 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 Creator/StanLee!
* Radio/TheGoonShow (and the work of Creator/SpikeMilligan in general) is the codifier for SurrealHumor.

[[folder: Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' 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 ArmorAndMagicDontMix, CharacterClassSystem, LinearWarriorsQuadraticWizards, and so forth.
** ''D&D'' also codified MagicAIsMagicA. Even if VancianMagic 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 [[StandardFantasySetting "Tolkien-style fantasy"]] despite Tolkienian magic having none of these traits.
** It's unclear whether or not ''Advanced TabletopGame/DungeonsAndDragons'' was the first to present an alignment system beyond good/neutral/evil[[note]]''Dungeons and Dragons'' used Lawful, Neutral and Chaotic for alignments. AD&D picked up from there and added good and evil as modifiers to all three.[[/note]], but it was definitely the most prominent, and its nine-point alignment system comprises all of the CharacterAlignment tropes today. Ironically, the most recent version of the game has done away with the alignment system, for the most part.
*** The OrderVersusChaos aspect was borrowed from Creator/MichaelMoorcock 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.
* The Zerg of ''VideoGame/StarCraft'' may have been the namers for ZergRush, but the Tyranids, of ''TabletopGame/{{Warhammer 40000}}'', were infamous for the tactic long before the Swarm came around. Of course, both being based on the Bugs from ''Franchise/StarshipTroopers'' the similarities are unavoidable, the result being an odd case where the [[TropeNamers Trope Namer]] came after the Codifier.
** Also the book also broke all the Bugs into castes of Worker and Warrior bugs, all directed by a special hierarchy of subterranean Brain Bugs.
* ''TabletopGame/{{Warhammer}}'' is a strong contender for the DarkFantasy genre.
* ''TabletopGame/{{Champions}}[=/=]Hero'' codified point-build systems, closely followed by ''TabletopGame/{{GURPS}},'' which seems to be the codifier for "system designed as generic from the start".
* ''TabletopGame/{{GURPS}}'' quite literally defined the WeirdnessMagnet trope. (ComicBook/BlueDevil is the Trope Maker here)
** With its iconic clean attribute/skill/advantage/disadvantage four-way split, ''[=GURPS=]'' is probably also the codifier for SkillScoresAndPerks. (''TabletopGame/{{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 UrExample for.)
* Although there were {{Trading Card Game}}s older than ''TabletopGame/MagicTheGathering'' (mostly using baseball cards), most of the tropes associated with modern [=TCGs=] started with Magic.

* Creator/WilliamShakespeare is another example; he 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.
* "Laurey Makes Up Her Mind" from ''Theatre/{{Oklahoma}}'' was the Trope Codifier for {{Dream Ballet}}s in musicals.
** ''Theatre/{{Oklahoma}}'' can also 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. ''Theatre/{{Oklahoma}}'' provided a template that other musicals used pretty much until Creator/AndrewLloydWebber showed up.
* Creator/GilbertAndSullivan didn't invent the PatterSong - there are examples of them going back over a century before G&S appeared on the scene (one early example from ''Theatre/DonGiovanni'' has the Don's servant singing out a LongList of his lovers and tastes). Gilbert and Sullivan made it their own however with two important changes: virtuoso rhymes for [[LeastRhymableWord Least Rhymable Words]] that often border on [[PainfulRhyme Painful]] (the MajorGeneralSong for example has ''strategy''/''sat a gee'', ''hypotenuse''/''lotta news'' and ''century''/''adventure-y''; "Matter Patter" from ''Theatre/{{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.

[[folder: Video Games]]
* QuickMelee has existed in some form in shooters, but the ''Franchise/{{Halo}}'' series is what started the trend in modern shooters, and the ''VideoGame/ModernWarfare'' series and ''VideoGame/CallOfDutyBlackOps'' are what made the "press a button to pull out your knife and stab with it in one motion" almost standard in recent shooters.
* ''VideoGame/Wolfenstein3D'' and ''VideoGame/{{Doom}}'' by Creator/IdSoftware weren't the first {{First Person Shooter}}s (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 [[CompetitiveMultiplayer Death matches]], FPS games with built in support for [[GameMod Game Mods]], [[TeleFrag telefragging your friends]], etc.
** In fact, Creator/JohnRomero coined the term ''deathmatch'' and ''frag''.
* ''VideoGame/DukeNukem3D'' 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 levels were infamously bland with green castle followed by grey castle followed by brown dungeon. Duke had levels with never before seen interactivity. Light switches, mirrors, CCTVs, wall sockets that electrocute you, televisions, rooms that make sense (like a bar, hotel rooms, nightclubs, reactors for the moonbase).
* The infamous Rockstar Games masterpiece, ''VideoGame/{{Manhunt}}'', is the mascot for [[MurderSimulators supposed video games that turns people into sadistic killers]]. Even going so far as that, 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 [[http://gamepolitics.com/2007/03/16/breaking-take-two-sues-jack-thompson lawyers and parents alike]].
** It only got worse when they release a sequel Manhunt 2, which was playable on the Wii. Yes, you can play the game in near virtual simulation with [[http://www.engadget.com/2007/02/10/manhunt-2-on-wii-a-true-murder-simulator/ the Wii-mote as your "weapon"]].
* ''VideoGame/{{Breakout}}'' is the Trope Maker (and [[TropeNamers Trope Namer]]) for BreakingOut, but most future examples of the genre are more based on Trope Codifier ''VideoGame/{{Arkanoid}}'', which added in power-ups.
* ''VideoGame/{{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. Bungie's ''VideoGame/{{Marathon}}'' is the UrExample, ''The Terminator: Future Shock'' is the Trope Maker, but due to ''Marathon'' being on the 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.
* Even though ''VideoGame/{{DOOM}}'' was the UrExample of the SpaceMarine trope in videogames, ''Franchise/{{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 [[LimitedLoadout limited inventory]], to RegeneratingHealth, to QuickMelee 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.
* ''Franchise/SuperMarioBros'' was the Codifier for {{Platform Game}}s (see Wiki/TheOtherWiki's [[http://en.wikipedia.org/wiki/Platformer#Scrolling_era article on platform games]]).
** And ''VideoGame/SuperMario64'' was definitely not the Trope Maker for 3D Platformers (see Wiki/TheOtherWiki's [[http://en.wikipedia.org/wiki/Platformer#Third_dimension article on platform games]]), but was definitely what all later games imitated.
** Not to mention ''VideoGame/SuperMarioWorld'' having the Codifier (and [[Administrivia/RenamedTropes former]] [[TropeNamers Trope Namer]]) for PowerupMount.
*** And then we have the romhacks... ''VideoGame/KaizoMarioWorld'' codified PlatformHell (and, [[TropeNamer of course]], KaizoTrap).
** Also worth noting is ''VideoGame/MarioParty'', 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.'' is ''VideoGame/DonkeyKong'', which popularized the platformer genre and also codified ThrowABarrelAtIt.
* ''VideoGame/EverQuest'' is the Trope Codifier for just about 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 ''VideoGame/WorldOfWarcraft''.
** ''VideoGame/WorldOfWarcraft'' later became a second Trope Codifier for the MMO genre.
* ''VideoGame/{{Pong}}'' is usually considered the first VideoGame by the general public. The ''actual'' first VideoGame is debatable depending on how you define VideoGame, ranging from an unnamed game of VideoGame/CathodeRayTubeAmusementDevice in 1947 to the 1972-released UsefulNotes/MagnavoxOdyssey game console (the strongest contender turning out to lie smack in the middle, 1962's ''VideoGame/SpaceWar!''), but the consensus is that Pong is the Trope Codifier rather than the true Trope Maker.
* ''[[VideoGame/{{Warcraft}} Warcraft II]]'', while not the first RealTimeStrategy game, ''was'' the first one to formalize the RPG aspects, including clearly visible hit point counters and {{Hero Unit}}s.
* Similarly, ''[[VideoGame/CommandAndConquer Command & Conquer II]]'', which codified and formalized the supporting abilities, heavy emphasis on counter-play and CripplingOverspecialization.
* Although there were definitely 3D beat'em ups/hack-and-slashers in the [=PS1=]/Sega Saturn/Nintendo 64 era, the first ''VideoGame/DevilMayCry'' gave the genre new popularity and credence and is widely seen as the key inspiration for similar "Stylish Action" games like ''VideoGame/GodOfWar''. 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.
* ''VideoGame/StreetFighterII'' for {{Fighting Game}}s.
** Also, Ryu is this to {{Shotoclone}}s.
* ''VideoGame/CapcomVsWhatever'' games for the concept of "tag battle" fighters (discounting wrestling games, which have wildly different gameplay.)
* ''VideoGame/SuperSmashBros'' popularized the PlatformFighter subgenre of fighting games.
* VideoGame/ResidentEvil for the SurvivalHorror despite not being the first of its kind.
** ''VideoGame/ResidentEvil4'' for the AlwaysOverTheShoulder ThirdPersonShooter.
* For the 3D FightingGame, ''VideoGame/{{Tekken}}'' is the most likely codifier, bringing together concepts introduced in [[TropeMakers preceding 3D fighters]] like ''VideoGame/VirtuaFighter'' and ''VideoGame/BattleArenaToshinden''.
* 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 [[StopPokingMe units giving ever more amusing responses if you won't leave them alone]].
* ''VideoGame/{{Worms}}'' codified the turn-based artillery gameplay of games like Gorillas and Artillery.
* While ''VideoGame/{{Recca}}'' probably was the UrExample and ''Batsugun'' was definitely the Trope Maker, ''[[VideoGame/DonPachi DoDonPachi]]'' codified very much of BulletHell. And it continues to redefine and codify the meaning of it as the TrueFinalBoss Hibachi has progressively gotten harder and harder [[NintendoHard beyond belief]].
* ''VideoGame/DragonQuestIII'' is the video game where the EasternRPG truly became a separate genre from the WesternRPG, and set the template for all other [=JRPGs=] to follow, including rival series ''Franchise/FinalFantasy'' and ''VideoGame/PhantasyStar''.
* ''VideoGame/GrandTheftAuto'', particularly ''VideoGame/GrandTheftAutoIII'', codified the WideOpenSandbox genre.
* ''Franchise/{{Pokemon}}'' is the codifier for the [[{{Mon}} monster-capturing]] game genre, [[TropeMakers predated by]] the DarkerAndEdgier ''Franchise/ShinMegamiTensei'' series.
* TowerDefense games were one of the major categories of user-made maps in ''VideoGame/StarCraft'', 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. ''VideoGame/{{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.
* Also on mods/user-made maps, ''VideoGame/DefenseOfTheAncients'' is not the Maker for MultiplayerOnlineBattleArena. The concept was Made by ''Aeon of Strife'' from the ''VideoGame/StarCraft'' 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 ''VideoGame/LeagueOfLegends'' or ''VideoGame/{{Demigod}}'' would not exist without it.
* ''VideoGame/{{Unreal}}'' is the codifier for SecondaryFire, as every weapon in the game has an alternative firing option. This persisted through the entire Unreal series, including [[VideoGame/UnrealTournament Tour]][[VideoGame/UnrealTournament2004 na]][[VideoGame/UnrealTournamentIII ment]] games, and is now considered virtually mandatory in any FPS game.
* ''VideoGame/GearsOfWar'' took the idea of TakeCover 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.
* ''VideoGame/{{Metroid 1}}'' was [[TropeMakers the first]] {{Metroidvania}}-game, and ''VideoGame/SuperMetroid'' is the Trope Codifier.
* ''VideoGame/TheLegendOfZelda'' codified the ActionAdventure genre, boasting innovations such as a battery save feature and open-ended gameplay, while eliminating irrelevant tropes such as ScoringPoints. However, it was predated by ''VideoGame/{{Adventure}}'' for the Atari 2600.
* While most certainly not the first SurvivalHorror game, ''Franchise/SilentHill'' introduced, or at least popularized atmosphere with limited visibility that maximizes NothingIsScarier.
* While ''VideoGame/DuneII'' is the most likely candidate for the very first RealTimeStrategy, ''VideoGame/CommandAndConquer'' pioneers many of the features that are present in the genre.
** ''VideoGame/BattleRealms'' isn't popular, but due to its complexity and variety of units, also qualify.
* While ''VideoGame/ModernWarfare'' 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 ''VideoGame/{{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 DeathFromAbove/fire support.
* ''VideoGame/TwistedMetal'' wasn't the first competitive VehicularCombat game (Both ''Battlesport'' and ''Cybersled'' predates it), but it certainly did popularize the genres and some features, such as tournament-based storylines, quirky characters and more differentiated vehicles.
* The {{Roguelike}} genre has two important codifiers: ''VideoGame/NetHack'' introduced many features that have since become commonplace in the genre and ''VideoGame/{{Angband}}'' created a whole, thriving sub-genre of its own. Additionally, the [[VideoGame/ShirenTheWanderer Mystery Dungeon series]] established many standards for roguelikes made by Japanese developers.
* Any new WideOpenSandbox [[SimulationGame space simulator]] is highly likely to be compared to at least one of three games: ''VideoGame/{{Freelancer}}'', the ''VideoGame/{{X}}-Universe'' series, and ''VideoGame/EVEOnline''. The latter two are better known among younger gamers that may not be familiar with ''Freelancer''[[note]]While ''Freelancer'' did come out later than ''VideoGame/XBeyondTheFrontier'', the ''X'' series got new entries and continuous updates throughout the [[TurnOfTheMillennium 2000's]], while Chris Roberts was in a ten-year vacation from game-making.[[/note]]. Single-player sims are more likely to be compared with ''X'', Egosoft being essentially the only [[{{Pun}} 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 ''VideoGame/StarCitizen'' has drawn comparisons to both.\\
Those games in turn owe much of their formula to the ''VideoGame/{{Elite}}'' series, the Trope Maker for {{Wide Open Sandbox}}es in general.
* Fighting massive creatures in games isn't anything new, however, after ''VideoGame/ShadowOfTheColossus'' came along; taking on behemoths would never be the same again. Hence, the ColossusClimb.
* The two most common forms of contemporary WesternRPG were codified by Creator/{{Bethesda}} and Creator/BioWare after the genre's crash in the mid-90ies:
** ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'' (and ''Franchise/TheElderScrolls'' series in general) codified the exploration-driven single-character [=RPGs=] whose main appeal is the [[WideOpenSandbox absolute freedom of movement]] and a metric ton of diverse {{side quest}}s.
** The ''VideoGame/BaldursGate'' series (and most of Creator/BioWare's other games), meanwhile, codified the PlayerParty-based [=RPGs=] whose main appeal are the [[RagtagBunchOfMisfits quirky teammates]] and the story that presents a ton of [[KarmaMeter moral choices]].
* During the Golden Age of the WesternRPG, the codifier was ''VideoGame/{{Wizardry}}''. The first-person, party-based DungeonCrawler format became the standard format for computer [=RPGs=]. ''VideoGame/{{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 EasternRPG, and on Bethesda and [=BioWare=] in later years).
* ''VideoGame/DeadRising'' 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 ''Videogame/{{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 has 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), and ''Videogame/{{Left 4 Dead}}'' (2008) featured an achievement called "Zombie Genocidist" which required you to kill 53,59''5'' zombies, upping it by exactly one.
* ''VideoGame/SonicTheHedgehog'' for [[MascotWithAttitude Mascots With Attitude]]: following the original games' success, several other developers tried to FollowTheLeader. Some of the games made in the wake of Sonic's popularity, like ''VideoGame/CrashBandicoot'' and ''VideoGame/RocketKnightAdventures'', found modest success. Others, like ''VideoGame/AwesomePossum'', fell flat.
* ''Franchise/MetalGear'' for StealthBasedGames.
* ''VideoGame/{{Borderlands}}'' is the more notable Codifier for uniting the genres of FirstPersonShooter and {{Role Playing Game}}s into one lovely little franchise, although the RPG and loot system was originally codified by ''VideoGame/{{Diablo}}'', ''Borderlands'' still deserves this spot for the previously mentioned reason [[UpToEleven and then some]].
* Current RPG[=/=]MatchThreeGame hybrids take their cues from ''VideoGame/PuzzleAndDragons'', rather than the TropeMaker, ''VideoGame/PuzzleQuest''.
* The SanityMeter 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 ''VideoGame/EternalDarkness: Sanity's Requiem'' as a result, especially since that game used the meter to [[PlayingThePlayer screw with the]] [[TheFourthWallWillNotProtectYou player as well]].

[[folder:Visual Novels]]
* ''VisualNovel/HigurashiWhenTheyCry'', at least in Japanese media, probably codified [[CuteAndPsycho secretly unstable characters]].
* ''VisualNovel/SchoolDays'' is known for the PsychoticLoveTriangle of Matoko Itou, Kotonoha Katsura and Sekai Saionji. To say the least, [[WomanScorned it]] [[MurderTheHypotenuse can]] [[IfICantHaveYou end]] [[BadEnding VERY BADLY]].
* ''VisualNovel/UtaNoPrincesama'' helped form the general idea of male {{Idol Singer}}s in Japanese media, and especially the setup of putting them all in a music school to hone their skills.

[[folder: Webcomics]]
* ''WebComic/DarthsAndDroids'' is the codifier for the CampaignComic. While preceded by ''Webcomic/DMOfTheRings'', a lot of traits that showed up later (such as players having backgrounds and personalities outside of the game) were established by it.
* ''WebComic/TheOrderOfTheStick'', not only [[TropeMaker started]], but codified using stick figures to tell stories set in an RPGMechanicsVerse. Much FollowTheLeader has ensued. (See StickFigureComic for the full list.)
* The [[WebComic/RageComics Troll Face]] is the Codifier of the MemeticTroll, being the literal face of the trope.

[[folder: Web Original]]
* Wiki/{{Wikipedia}} is an encyclopedia, and so influential that [[TheWikiRule few wikis exist that aren't, functionally, specialized encyclopedias]] rather than, say, community projects or collections of cross-referenced essays. The most obvious counterexample, WebSite/EverythingTwo, predates Wikipedia.
*  Franchise/TheSlenderManMythos is the codifier for TheBlank, and with good reason.
* ''WebAnimation/HappyTreeFriends'': Lumpy codified MooseAreIdiots.
* While not the first VideoReviewShow, ''WebVideo/TheAngryVideoGameNerd'' popularized the format.
* Website/YouTube may not be the first video sharing website but it most ''certainly'' did made the idea solidified.
* WebVideo/KizunaAi isn't the first [[VirtualCelebrity "Virtual Youtuber"]] but she is responsible for coining the term, as well as popularising the use of motion-capture and [[{{Kayfabe}} framing videos as a real person filming themselves]] while [[ReclusiveArtist obscuring the performer behind them]]. Her "AI living in {{Cyberspace}}" persona also lead to many of [[FollowTheLeader her imitators]] making at least token gestures to being AmbiguouslyHuman and[=/=]or TrappedInAnotherWorld.

[[folder: Western Animation]]
* Creator/TexAvery, particularly in his short ''WesternAnimation/RedHotRidingHood'', codified the WildTake.
* ''WesternAnimation/AnAmericanTail'' codified the AwardBaitSong, which even spread into live action works.
* ''{{ComicStrip/Popeye}}'s'' spinach is the codifier for PowerUpFood.
* ''WesternAnimation/TheRenAndStimpyShow'' codified the GrossUpCloseUp and the GrossoutShow.
* ''WesternAnimation/WallaceAndGromit'' codified SilentSnarker. Seriously.
* WesternAnimation/WileECoyoteAndTheRoadRunner is the codifier for the IronButtMonkey.
* ''WesternAnimation/InspectorGadget'' codified both TheFool and the InspectorOblivious.
* ''WesternAnimation/TheSimpsons'' re-codified modern animated {{Sitcom}}s.
* WesternAnimation/BugsBunny codified {{Karmic Trickster}}s.
* ''WesternAnimation/ThePowerpuffGirls'' codified ActionGirl shows.

* ''Literature/DigitalDevilStory'' codified the Franchise/ShinMegamiTensei metaseries, providing the original source material that eventually set the rules for all {{Mons}}.
* An earlier work by Creator/WilliamGibson [[TropeNamers coined]] the term "{{Cyberspace}}". Both ''Literature/{{Neuromancer}}'' and ''Film/{{Tron}}'' set the standards for what we think of it.
* 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 OlderThanTheyThink.
* 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 [[JustForPun 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.
* Fortune teller characters nowadays will likely take some influence from Miss Cleo. This results in UsefulNotes/{{Romani}} with Jamaican accents.
* Clarence Darrow's defense of [[http://en.wikipedia.org/wiki/Leopold_and_Loeb Leopold and Loeb]] was the codifier for SocietyIsToBlame.
** 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).
* 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 [[OlderThanTheyThink they are often credited as the inventors]].
* 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 ProperlyParanoid characters.
* Creator/GeoffreyChaucer 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).
* UsefulNotes/StephenHawking is one for GeniusCripple.
* Charles II of Spain for RoyallyScrewedUp, 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.
* British actor Creator/SeanBean is the Codifier for the ChronicallyKilledActor. 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.
* For [[VirtualCelebrity Virtual]] {{Idol Singer}}s and the concept of an artificial singer in general, look no further than Hatsune Miku of the ''Music/{{Vocaloid}}'' system. While she has a predecessor in Sharon Apple of ''Anime/MacrossPlus'', her widespread popularity both in physical appearance and in voice make her one of the first thoughts people have regarding artificial celebrities.
* In one of the greatest upset victories in US election history, the 1948 presidential election between UsefulNotes/HarryTruman and Thomas Dewey is the Codifier of the AssumedWin. The photo of Truman proudly holding up the newspaper reading "DEWEY DEFEATS TRUMAN" remains one of the most iconic images of his presidency.
