-> ''"In a world... where [[Creator/MarvelComics a bankrupt comic book company]] sold the film rights of its best characters for peanuts, because they thought movies would be a good way to sell more comics, [[Creator/KevinFeige a young executive]] will do what he can with the rejects no one wanted, and do so well they get bought out by Creator/{{Disney}}... before it was cool."''

Works where the original was some gag idly doodled on cocktail napkins, and the "{{sequel}}" was a [[BigBudgetBeefUp multi-million dollar]] Hollywood project.

These may be considered a SpiritualSuccessor, SurprisinglyImprovedSequel, AdaptationExpansion or MorePopularSpinoff, and cause AdaptationDisplacement or SequelDisplacement, depending on what you consider a sequel, successor, adaptation, and original. A lot of people tend to assume that ItWillNeverCatchOn before becoming a SleeperHit.

[[folder:Anime and Manga]]
* ''Game Center Arashi'' was an early example of manga and anime focused on video gaming, and influenced many hobby series that would come after it. The choice to have its protagonist be a cartoony buck-toothed kid was a joke by Mitsuru Sugaya; he had drawn more conventional-looking designs for the lead to show to his editor, as well as a doodle of a boy with enormous buck teeth in the corner. The doodle won out, and in Japan Arashi's face and wild posing continues to be associated with gaming.
* The ''Franchise/LoveLive'' series began as a massive financial failure when their first single, "Bokura no LIVE, Kimi to no LIFE", sold a whole 434 copies on release, with most of the copies being bought by the voice actresses and their relatives to show support. After the [[Anime/LoveLive first anime]] took off, it gradually became a CashCowFranchise.
* The ''Franchise/LyricalNanoha'' franchise, which began as a mini-scenario included in the [[http://nanoha.wikia.com/wiki/Lyrical_Toy_Box Lyrical Toy Box]] merchandise CD of ''VideoGame/TriangleHeart3SweetSongsForever''.
* That's very much how ''Franchise/YuGiOh'' became associated with "Duel Monsters", which originally was only one of many games in the manga ("Yu Gi Oh" means "KingOfGames"). Then {{Defictionalization}} of said card game steadily happened, creating a globally known franchise worth billions of dollars in the process.
[[/folder]]

[[folder:Art]]
* The earliest version of what would eventually become ''Art/NorthAmericaPortraitOfAContinent'', as well as the beginning of Anton Thomas' career in cartography, [[https://www.antonthomasart.com/about.html was first drawn on a beat-up old fridge.]]
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/TwoThousandAD'': The popular series ''DR and Quinch'' began as a one-off ''[[{{Padding}} Future S.hock]]''.
* ''ComicBook/{{Empowered}}'': The comic began as a series of superhero-themed softcore BDSM pin-ups that Adam Warren did as a commission to make money. However, he then found the people in them developing personalities, which gave him some plot ideas...
* ''ComicBook/SpiderMan'': Spider-Man was treated as a throwaway character and put in [[ComicBook/AmazingFantasyNumber15 the last issue of a failing series]] because [[ItWillNeverCatchOn people thought he would be too weird for people to like]].
* ''ComicBook/{{Superman}}'': A SciFi {{comic strip}} repeatedly pitched by [[Creator/JerrySiegelAndJoeShuster two kids]] from UsefulNotes/{{Cleveland}}.
[[/folder]]

[[folder:Films -- Animated]]
* ''WesternAnimation/LiloAndStitch'' started out around 1985 when Creator/ChrisSanders drew a picture of a grotesque alien creature for a failed children's book pitch. He kept the creature, called "Stitch", in his mind as he worked on several [[Franchise/DisneyAnimatedCanon Disney animated films]] during the Disney Renaissance for years up to the mid-90s when Creator/{{Disney}}, who was looking to produce an animated film with a smaller budget than their big blockbusters, approached him to come up with a pitch for a new original film. After some tweaking to the story and character design, Sanders got to use his character for an animated film that would become Disney animation's one combined critical and commercial saving grace during their low period in the first half of the 2000s, even spawning [[Franchise/LiloAndStitch a successful franchise]] shortly thereafter.
* ''WesternAnimation/ToyStory1'' had its roots in ''WesternAnimation/TinToy'', a 5-minute short film about toys hiding from, and then wanting to be played with, a baby named Billy. A half-hour ''Tin Toy'' Christmas special was in the works as a testing ground to see if Pixar could manage a production that was closer to that of a feature-length film. In it, Tinny would have accidentally been sold to a toy store where he would discover he was part of a set of toy musicians that sold poorly. Another version of the story involved him being left behind on a family road trip where he'd team up with an abandoned ventriloquist dummy, and the two of them would make their way to a daycare center, where they'd be loved and played with forever. Disney wasn't interested and the studio couldn't afford to produce it independently, so Disney did the next best thing: they told the studio to start work on an honest-to-goodness feature film, which eventually became ''Toy Story''.
[[/folder]]

[[folder:Films -- Live-Action]]
* Creator/RobertRodriguez's ''Film/{{Desperado}}'', which was the remake/sequel of ''Film/ElMariachi'' which he made on a budget.
* ''Film/ShredderOrpheus'' started as a short 13-minute movie called ''Orpheus and Eurydice'' in 1983, was expanded into a 27-minute film in 1987 under the current title, and finally became a full-length feature in 1989.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/TheAddamsFamily'' started as a loosely-connected set of cartoons by Charles Addams in ''Magazine/TheNewYorker'' with recurring unnamed character designs. Until the proposal to create a show based on them, Addams had never even thought of them as named individuals.
* ''Series/DoctorWho'' is an arguable case. Classic series? [[NoBudget Duct tape sets, wardrobes from a thrift shop, special effects on par with a college film, and not enough money for proper explosions.]] But then the Americans got a hold of it for the TVMovie and decide to go with a budget and production values similar to what Americans were used to in their TV sci-fi. And when the new series kicked in, they continued with the higher-end budget and production.
[[/folder]]

[[folder:Music]]
* "Music/GetHappy" began as a short vamp that Music/HaroldArlen improvised while substituting for Fletcher Henderson as rehearsal pianist on the 1929 Broadway musical flop ''Great Day!''. The chorus director, Will Marion Cook, told Arlen to turn it into a popular song, and it indeed became the BreakthroughHit of his songwriting career.
* ''Music/HypnosisMic'' began with an empty mall performance of "Division Rap Battle" before expanding into the elaborate stage shows and concerts it's now known for.
[[/folder]]

[[folder:Newspaper Comics]]
* ComicStrip/{{Dilbert}} started out as an unnamed recurring character drawn on the whiteboard of Creator/{{Scott Adams|Cartoonist}}' cubicle while working as an engineer at Pacific Bell.
* ''Webcomic/GarfieldMinusGarfield'', which started as a riff of a MemeticMutation of ''ComicStrip/{{Garfield}}'' (inspired in a thread on the Truth and Beauty Bombs forum about the Garfield Randomizer), and eventually got ''its own published book by the syndicate, with a commentary essay by Creator/JimDavis''.
[[/folder]]

[[folder:Theatre]]
* The Creator/ReducedShakespeareCompany began as a Renaissance Faire act doing a twenty-minute abridgement of ''Theatre/{{Hamlet}}''. Over the better part of a decade, this developed into a full-length theatrical work, ''Theatre/TheCompleteWorksOfWilliamShakespeareAbridged''.
* ''Theatre/ForbiddenBroadway'' began as a cabaret act with a cast of only three, including both Gerard Alessandrini and the pianist (who had to be replaced at the last minute, causing some worry since no piano part had been written out). They could hardly keep up with the costume changes.
* ''Theatre/{{Hamilton}}'' began as a single rap (which eventually became the opening number, ''Alexander Hamilton'') performed at the White House by Creator/LinManuelMiranda, who had been invited to perform something from ''Theatre/InTheHeights'' (which was on Broadway at the time). To make matters worse, when he announced what he was about to perform, Barack and Michelle Obama [[ItWillNeverCatchOn laughed at him]].
[[/folder]]

[[folder:Toys]]
* ''Toys/{{Uglydolls}}'' started with David Horvath and Sun-Min Kim, two university students, separated from each other due to Sun-Min's student visa expiring and her having to move back to Korea before a franchise could start. David wrote her a letter of support with a drawing of the character that would become Wage on it, and she sewed a doll of him as a gift in return. Through an incident that made it seem like they were pitching a toy, more dolls were sewn, more characters were added, and the toy-line was born.
[[/folder]]

[[folder:Video Games]]
* Creator/{{Nintendo}}:
** Perhaps most famously, Creator/{{Nintendo}} started as a card company in the 19th century. Later they moved onto toys and novelties, before eventually getting into VideoGames, which made them an international name.
** The [[VideoGame/SuperSmashBros64 first]] ''VideoGame/SuperSmashBros'' game started out as a side-project that Creator/MasahiroSakurai and other Creator/HALLaboratory staff worked on during weekends in an attempt to create an easy-to-pick-up fighting game. The game wasn't even conceived as a crossover at first; Sakurai introduced the idea of using pre-established Nintendo characters midway through development due to his belief that the game would need a cast of recognizable characters to stand out in the crowded fighting game market. The combination of the recognizable characters and accessible gameplay turned the game into a SleeperHit in spite of its lack of budget. Thanks to better hardware and proper budgets, subsequent ''Smash'' games would go on to achieve even greater success, becoming {{Killer App}}s for future Nintendo systems and giving rise to yet another CashCowFranchise for Nintendo.
* ''VideoGame/MadballsInBaboInvasion'' was the sequel to the one-man freeware program ''Babo Violent 2'', which was itself the formalized version of a ''networking test''.
* ''VideoGame/GeometryWars: Retro Evolved'', which was the Platform/XboxLiveArcade version of an EasterEgg MiniGame from ''VideoGame/ProjectGothamRacing'' originally created ''for testing the input system'', and has since become [[MorePopularSpinoff a lucrative franchise in its own right]].
* ''VideoGame/AlienHominid'' and ''VideoGame/MeatBoy'', originally just random Flash games on Platform/{{Newgrounds}}.
* ''VideoGame/LineRider'', a Flash toy with nothing more than drawing a line for a sled to ride on, which later got a full-fledged sequel and social networking website.
* ''VideoGame/TeamFortress2'', technically the sequel to a 2-or-3 man mod for ''VideoGame/{{Quake}}''.
* The games ''VideoGame/CounterStrike'' and ''VideoGame/DayOfDefeat'', which were both ''VideoGame/HalfLife'' mods whose small dev teams were bought out by Valve, split into commercial packages, and followed with "Source" versions with a much-improved engine.
* The initial development idea for ''VideoGame/Left4Dead'' came during the development of bots for ''VideoGame/CounterStrike'', where the developers found themselves having more fun by arming a legion of bots with only knives and then fighting them off like a zombie horde.
* ''VideoGame/GarrysMod'', the ten-dollar commercial version 10 of which has made Garry effectively a millionaire, was originally a quick hack to the leaked ''VideoGame/HalfLife2'' source code to allow arbitrary rope creation posted on the Website/SomethingAwful Forums.
* The game that preceded ''VideoGame/{{Portal}}'', ''VideoGame/NarbacularDrop'', was a school project at [=DigiPen=].
* ''VideoGame/DefenseOfTheAncients'', a ''VideoGame/{{WarCraft}} III'' [[AbridgedArenaArray map]] with ''its own work page'', has inspired a ''top ten single charting theme song'', quite a few popular games, among them ''VideoGame/{{Demigod}}'', ''VideoGame/HeroesOfNewerth'', and ''VideoGame/LeagueOfLegends'', and arguably its own ''[[MultiplayerOnlineBattleArena genre]]'', and scored its developer a position at Valve Software (they seem to have a thing for AscendedFanboy developers).
* The idea for ''VisualNovel/KatawaShoujo'' began as a one-off joke on an {{omake}} page of a manga. Later, some people saw it on Website/FourChan and decided to take a serious crack at making a VisualNovel featuring girls with disabilities.
* Kind of a borderline example, but ''VideoGame/KerbalSpaceProgram'' is named after the backstory a couple of the developers made up for a series of model rockets they built and launched together when they were kids.
* Creator/{{Rare}}'s Mr. Pants made his first appearance on their website's Survey page as a hastily doodled placeholder character. He eventually starred in his own Platform/GameBoyAdvance game.
* ''VideoGame/{{Parodius}}'' became the most popular of the ''VideoGame/{{Gradius}}'' series' various spinoffs, but the inspiration for the cheaply-produced Platform/{{MSX}} game, which preceded the flashier, [[SequelDisplacement more popular]] arcade and console games, seems to have been the [[SillinessSwitch joke option]] of playing as VideoGame/{{Twinbee}} in ''Gradius'' by [[OldSaveBonus plugging cartridges for both games into one MSX]].
* ''VideoGame/FreedomPlanet'' started as a FanGame of ''Franchise/SonicTheHedgehog'' with original characters that took inspiration from the frantic and over the top action games by ''Creator/{{Treasure}}''. When the team realized how much work was being put into the original characters and unique mechanics, they decided to remake the project as its own IP that was a celebration of the ''Platform/SegaGenesis'' library with a Sonic-influenced art style that became a successful franchise in its own right with [[VideoGame/FreedomPlanet2 a sequel]], widely praised as a unique series that does what ''VideoGame/ShovelKnight'' did for 8-bit games that FP did for Creator/{{Sega}} platformers.
* ''VideoGame/ShiningInTheDarkness'' was developed on NoBudget (as the developer admitted in a 2009 interview; despite being a first-party in-house title they were only given the bare minimum budget offered to 3rd-party developers) solely to pad out the Platform/SegaGenesis' then-threadbare library of [=JRPGs=]. When Sega decided they wanted to create their own strategy RPG series to rival Nintendo's ''Franchise/FireEmblem'', they chose to revisit the world of ''Shining in the Darkness'' and [[VideoGame/ShiningSeries the rest was history]].
* ''VideoGame/HotlineMiami'' traces its origins back to a short, endless one-floor level called ''Super Carnage'' released to a forum in 2005.

[[folder:Web Animation]]
* Alan Becker was a financially struggling JuniorHigh student when he made a two-minute short called ''WebAnimation/AnimatorVsAnimation'' in his spare time, never expecting it to dominate the UsefulNotes/WebTwoPointOh scene, become the subject of Internet controversy, and eventually form the basis of his animation career. [[https://www.youtube.com/watch?v=1zj5mj1DHOk Here's the full story.]]
* Creator/GlitchProductions:
** ''[[WebAnimation/Supermarioglitchy4sSuperMario64Bloopers SMG4]]'' began in 2011 as any other ''WebAnimation/SuperMario64Bloopers'' series on Platform/YouTube, starting with a two-and-a-half minute video made by teenager Luke Lerdwichagul about Mario getting invited for cake and hearing [[MemeticMutation the cake is a lie]]. By 2017, Luke and his brother, Kevin, had improved their animation and storytelling skills so much that ''[=SMG4=]'' became a [=YouTube=] staple, raking in millions of views per weekly episode, and inspiring the brothers to start Glitch as their own successful indie animation studio.
** ''WebAnimation/MetaRunner'', Glitch's first original IP, stems from a drawing of a new character Kevin and Luke asked their younger sister to make for ''[=SMG4=]''. That character was Tari, ''Meta Runner''[='=]s eventual protagonist, whom the brothers decided to make the focus of her very own show before working her back into ''[=SMG4=]'' as a bit of ProductionForeshadowing.
* ''WebAnimation/HomestarRunner'', which now has its own professional video game series and cameos ranging from songs in ''VideoGame/GuitarHero'' to an EasterEgg cartoon ''in a Macromedia program'', started as [[Literature/TheHomestarRunnerEntersTheStrongestManInTheWorldContest a children's book made in a college afternoon]] and put together at ''Kinko's.'' [[http://www.hrwiki.org/wiki/Original_Book Watch it here.]]
* ''WebAnimation/RedVsBlue'' was a one-off trailer [[Creator/RoosterTeeth a bunch of drunk college friends]] put together inspired by early ''VideoGame/{{Quake}}'' {{Machinima}} and their obsession with a new game they were playing called ''VideoGame/HaloCombatEvolved''. When some fans on the very early internet liked it, demand grew for a proper series, which they eventually started in 2003 using rough capture footage from their consoles filming the popular multi-player game of capture the flag. What started as a nonsensical sitcom with Halo characters swearing and [[LampshadeHanging lampshading]] the video game logic eventually grew into a surprisingly complex and ever-growing plot with dozens of developed characters, semi-professional and professional actors, custom CGI animated sequences, an indie rock band to perform the background music, and interconnected epic of war, betrayal, the ethics and morality of artificial intelligence, and comrades in battle while maintaining the witty humor and hilarious banter between ''Halo'' characters.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/TheAdventuresOfDrMcNinja'' started as Chris Hastings' ''user name'' on the Website/SomethingAwful Forums, which he decided at the last moment to change from Dr. [=McNugget=]. He then drew a panel of what said doctor would look like, then used the doctor as the premise of a comic he drew for his art degree.
* The ''Webcomic/NuzlockeComics'' originally started out as the sketchings of a SelfImposedChallenge on a ''[[VideoGame/PokemonRubyAndSapphire Pokémon]]'' run. It utilised [[http://www.nuzlocke.com/pokemonhardmode.php?p=1 stick figures with a storyline that didn't really deviate from the original game]] for the first season, but, come [[VideoGame/PokemonFireRedAndLeafGreen the next]] [[http://www.nuzlocke.com/pokemonhardmode.php?p=15 season,]] there's [[ArtEvolution a noticeable improvement in the artwork and formatting]], the story-line becomes much more substantial, and the Pokémon themselves were much better characterized. The challenge itself has also become extremely popular among others, inspiring many other Nuzlocke comics, prose and further creative pursuits in turn.
* ''Webcomic/GunnerkriggCourt'' began as a picture Tom Siddell drew of a pink-haired girl in a drab school uniform. He only chose that subject for his picture because it fit the marker colors he had on hand. These days, ''Gunnerkrigg Court'' is Tom's sole source of income.
* Creator/GigiDG publicized ''Webcomic/CucumberQuest'''s humble origins as part of an AprilFoolsDay gag in 2014. For the day, they revamped the site as ''Kukobu Quest'', featuring their own art and writing from ten years prior.
* ''Webcomic/{{morphE}}'' began as a weekly World of Darkness game between the four creators. The game spanned for two and a half years and spawned the plot of the comic. The weekly game itself was spawned from a one-shot test game the lead creator ran with a larger pool of friends. There was no intent to expand the one-shot to a full campaign, nor to adapt the outcome. The story just kept growing.
* The first ''Webcomic/{{xkcd}}'' strips were doodles from Creator/RandallMunroe's notebooks.
* ''Webcomic/BrawlInTheFamily'' started out as silly doodles on Smashboards, and since gained its author the notoriety to launch several highly successful Website/{{Kickstarter}} campaigns (including one for his own IndieGame, ''VideoGame/TadpoleTreble'') and land a position in the ''Magazine/NintendoForce'' fan-{{magazine}}.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'', originally [[https://static.tvtropes.org/pmwiki/pub/images/Simpsons_on_Tracey_Ullman.png a crudely-drawn series of shorts]] on ''Series/TheTraceyUllmanShow'', has gone on for [[LongRunners more than 30 seasons]] and has spawned a merchandising empire, several {{video games}}, a [[WesternAnimation/TheSimpsonsMovie movie]] and [[Ride/TheSimpsonsRide ride]]. The characters themselves were knocked out in the waiting room where Creator/MattGroening was going to meet with executives. Originally, he was going to pitch a show based upon his comic ''ComicStrip/LifeInHell'', but he realized at the last minute that he might lose the rights to his own characters, so he quickly sketched a NuclearFamily based upon his own family.
* Creator/TreyParkerAndMattStone's first short [[https://www.youtube.com/watch?v=kxZ0X9fMQZ4 "Jesus Vs. Frosty"]] was done as a ''student film''. Their second short was made on a budget for a Fox network executive... so he could use it as ''a video Christmas card to send to his friends''. After months of underground circulation via bootleg tapes and {{the Internet}}, Creator/ComedyCentral decided to hire them to expand this into ''WesternAnimation/SouthPark''.
* The genesis for ''WesternAnimation/PhineasAndFerb'' came one night when Dan Povenmire was at a restaurant and drew a triangle-headed boy and decided to build a show around him. It was sixteen years before the show actually got picked up. The show's villain, now known as Dr. Doofenshmirtz, first appeared in an ad for Middlefield Cheese, an Ohio Amish cheese company in 2004.
* ''WesternAnimation/BeavisAndButtHead'' was originally just a short on ''WesternAnimation/LiquidTelevision'', likewise ''WesternAnimation/AeonFlux''. ''WesternAnimation/CelebrityDeathmatch'' appeared on the show's SpiritualSuccessor ''WesternAnimation/CartoonSushi''.
* ''WesternAnimation/MikeLuAndOg'' grew out of a Russian animated short by Mikhail Aldashin about island natives being introduced to modern conveniences. The execs at Creator/CartoonNetwork thought it would be a good premise for a series and hired Chuck Swenson (fresh from Creator/KlaskyCsupo) as head writer and Mikhail Shindel as producer to develop the series in collaboration with Pilot Studio in Moscow, with Swenson creating the redheaded tomboy to serve as the central character.
* ''WesternAnimation/TheBoondocks'' started out as a college newspaper strip before being nationally syndicated and eventually getting [[AnimatedAdaptation a popular television series]].
* Before becoming the massive franchise that [[CashCowFranchise earned millions of dollars]] for Creator/{{Nickelodeon}}, ''WesternAnimation/SpongeBobSquarePants'' started life as Bob the Sponge in a pamphlet comic made by Steven Hillenburg called ''ComicBook/TheIntertidalZone'' for children visiting the Orange County Marine Institute where he worked at. About a decade later, he revamped the concept to make a pitch for Nickelodeon, and the rest was history.
* Long before ''WesternAnimation/ThomasAndFriends'' was a global sensation, it was a series of bedtime stories told by an English clergyman named Creator/WilbertAwdry as a way to entertain his very young son Christopher when he was ill with the measles. These bedtime stories came to be compiled in the first books of ''Literature/TheRailwaySeries''.
[[/folder]]

[[folder:Other]]
* UsefulNotes/AdobeFlash, originally a small vector animation system based off a tablet computer drawing program by an Aldus spinoff later acquired by Macromedia. With its browser-embeddable Flash (originally [=FutureSplash=]) player, the introduction of [=ActionScript=] (Javascript with the SerialNumbersFiledOff,) and especially its late addition of bitmapped video, by the time Macromedia was acquired for Adobe, Flash had become the most popular browser-based content delivery medium.
* {{Platform/Yahoo}}, which began in 1994 as a student project on the Stanford University site. As did Website/{{Google}}.
* Website/{{IMDb}} started as a list of actresses with [[WhatBeautifulEyes pretty eyes]].
* [[Website/TVTropes This Very Wiki]] started out on Website/BuffistasOrg, a ''Franchise/{{Buffyverse}}'' fan-site.
* eBay began because the creator's girlfriend had some Pez dispensers she wanted to sell.
* Ken Thompson and Dennis Ritchie began developing the Platform/{{UNIX}} operating system on the PDP-7, an under-powered minicomputer. Before development moved to the PDP-11 and added text-processing applications that made Bell Labs take more than an experimental interest in UNIX, it was little more than a set of utility programs supporting a port of ''VideoGame/SpaceTravel'', a game Thompson had originally written for a more powerful mainframe while working on MULTICS.
* The Linux kernel started out, in the words of its creator Linus Torvalds, as "just a hobby" that he didn't think would ever become "big and professional" or ported to any other system besides his own 386 PC. Today, Linux has become ubiquitous on a multitude of different devices and platforms, including servers, embedded devices, as well as smartphones thanks to Android using it as its kernel.
