This is the very work that practically begins a creator's career and gives them success in their medium. This is the [[TitleDrop Breakthrough Hit]].

For some creators, it could be the very first work they created. For others, it comes only after a series of unsuccessful attempts, although these early attempts may end up being VindicatedByHistory. For many of these, creators are often subject to the curse of ToughActToFollow, as practically every subsequent work may be compared to the breakthrough.

Compare KillerApp (equivalent for game systems), StarMakingRole (equivalent for actors), and GatewaySeries (equivalent for an entire genre or multimedia franchise). Contrast CreatorKiller and OneHitWonder.

* ''Film/AmericanGraffiti'' for Creator/GeorgeLucas. However, ''[[Film/ANewHope Star Wars: A New Hope]]'' made him such a household name that it's often forgotten that it was advertised as being "from the director of ''American Graffiti''."
* ''Film/{{Jaws}}'' for Creator/StevenSpielberg. It was actually his fifth film; his firsts, ''Film/TheSugarlandExpress'', and ''Film/{{Duel}}'' and a host of other TV movies he directed are long forgotten today.
* ''Film/{{Alien}}'' for Creator/RidleyScott. While his debut film ''Film/TheDuelists'' is critically well regarded, it's been largely forgotten by mainstream audiences.
* ''Film/TheLordOfTheRings'' put Creator/PeterJackson on the world stage, though ''Film/HeavenlyCreatures'' is the film that brought him to Hollywood.
* ''Film/PulpFiction'' for Creator/QuentinTarantino. ''Film/ReservoirDogs'' became a retroactive cult classic off of the success of ''Pulp Fiction''.
* ''Film/TheGodfather'' for Creator/FrancisFordCoppola. He won an Oscar for his screenwriting in 1970's ''Film/{{Patton}}'', but he was still considered an unknown quantity when he helmed ''The Godfather''.
* ''Film/TaxiDriver'' for Creator/MartinScorsese. He had two major releases prior to the film: ''Film/MeanStreets'' and ''Film/AliceDoesntLiveHereAnymore.'' The former, while highly praised and a modern-day classic, was a flop upon release, whereas the latter, although more successful and Oscar-winning, didn't exactly have Scorsese's directorial work at the center of the acclaim. ''Taxi Driver'' is viewed as the film that made him a household name.
* ''Film/{{Carrie|1976}}'' for Creator/BrianDePalma. After a series of independent studio films, ''Carrie'' became his first hit.
* ''Film/{{Clerks}}'' for Creator/KevinSmith. It was an indie film, but it made his name and led to big-budget projects.
* ''Film/RomancingTheStone'' for Creator/RobertZemeckis. At the time, Zemeckis was known for directing two commercial flops and writing the screenplay to Steven Spielberg's ''Film/NineteenFortyOne''. ''Film/BackToTheFuture'' was a further breakthough for him afterwards.
* ''Film/{{Halloween 1978}}'' for Creator/JohnCarpenter. Many of his earlier films are now seen as cult classics, but Carpenter's first genuine hit came with the 1978 slasher.
* ''Film/RosemarysBaby'' for Creator/RomanPolanski.
* ''Film/AnimalHouse'' for Creator/JohnLandis.
* ''Film/TheUsualSuspects'' for Creator/BryanSinger and screenwriter Christopher [=McQuarrie=]
* ''Film/{{Pi}}'' for Creator/DarrenAronofsky. This indie film was lauded by critics and made his name in the industry.
* ''Film/{{Memento}}'' for Creator/ChristopherNolan, although he didn't really become a household name until ''Film/TheDarkKnightSaga''.
* ''Film/ElMariachi'' and later ''Film/{{Desperado}}'' for Creator/RobertRodriguez.
* ''Film/WhatsNewPussycat'' for Creator/WoodyAllen. As a writer/director, it was ''Film/TakeTheMoneyAndRun''.
* ''Film/{{Platoon}}'' for Creator/OliverStone. He was an established screenwriter at the time, known for his work in ''Film/{{Scarface 1983}}'' and ''Film/ConanTheBarbarian1982.'' ''Platoon'' was his first hit as a director.
* ''Film/{{Laura}}'' was the film that made Creator/OttoPreminger's career as a producer-director, though he had not only directed several previous films but produced one as well (''In the Meantime, Darling'').
* ''Film/BoogieNights'' for Creator/PaulThomasAnderson. ''Film/HardEight'', his first feature film, never made it past a limited release.
* ''Film/{{Fanboys}}'' for Creator/KyleNewman.
* ''Film/{{RoboCop|1987}}'' for Creator/PaulVerhoeven internationally. He was well known in the Netherlands for years.
* ''Film/ThreeKings'' for Creator/DavidORussell. He enjoyed an ever more successful period starting with ''Film/TheFighter'' in 2010.
* ''Film/SaturdayNightFever'' for Creator/JohnBadham. ''The Bingo Long Traveling All-Stars,'' his first film, went largely unnoticed.
* ''Film/TheOmen1976'' for Creator/RichardDonner.
* ''Film/{{Splash}}'' for Creator/RonHoward as a director. ''Film/NightShift'' was a moderate hit for him, but is today remembered for ''That's What Friends Are For,'' which became a future hit collaboration for Dionne Warwick, Music/EltonJohn, Music/StevieWonder, and Gladys Knight.
* ''Film/DoTheRightThing'' for Creator/SpikeLee.

* ''Literature/TheAndromedaStrain'' for Creator/MichaelCrichton.
* ''Literature/HortonHatchesTheEgg'' for Creator/DrSeuss.
** While ''Horton'' was his most popular book at the time, it was when ''Literature/TheCatInTheHat'' hit the shelves that he became a household name.
* ''Literature/TheHungerGames'' for Creator/SuzanneCollins. Her previous book series, ''The Underland Chronicles'', was not very successful and did not gain retroactive recognition upon "The Hunger Games"' success.
* ''Literature/{{Carrie}}'' for Creator/StephenKing. Although it was released on a low print run, its successful movie adaptation brought newfound attention onto the book and King.
* Miguel de Cervantes was regarded as a very mediocre playwright and author of a mildly successful pastoral romance before he published ''Literature/DonQuixote''. The rest is history.
* ''Literature/HarryPotterAndThePhilosophersStone'' for Creator/JKRowling.
* ''{{Literature/The Dresden Files}}'' for Creator/JimButcher.
* ''{{Literature/The Adventures of Tom Sawyer}}'' for Creator/MarkTwain.
* ''Literature/TheHuntForRedOctober'' for Creator/TomClancy.
* ''Literature/TheFaultInOurStars'' for Creator/JohnGreen. He has had many popular books before this, but this was his first massive hit and the book that really brought him into public eye. In 2014 alone, only the ''Literature/{{Divergent}}'' trilogy has been able to rival it in sales.
* ''Literature/AGameOfThrones'' for Creator/GeorgeRRMartin (although it was the TV adaptation, ''Series/GameOfThrones'' that got him mainstream recognition).
* ''TabletopGame/{{Warhammer 40000}}'' for Creator/DanAbnett.

[[folder:Live Action TV]]

* ''Series/AllThat'' for DanSchneider.
* ''Series/LawAndOrder'' for Creator/DickWolf.
* ''Series/BuffyTheVampireSlayer'' for Creator/JossWhedon, Creator/JaneEspenson and David Greenwalt. It also gave a start for Steven S. [=DeKnight=] (''Series/{{Spartacus}}'' and ''Series/{{Daredevil 2015}}'') and Drew Goddard (''Film/TheCabinInTheWoods'').
* ''Series/{{CSI}}'' for Jerry Bruckheimer as a TV producer (since he was already famous for his film work).
* ''Series/VeronicaMars'' started Rob Thomas's career as a television producer, although his book ''Rats Saw God'' started his career as a novelist.
* ''Series/{{Heroes}}'' for Tim Kring (although his previous series ''CrossingJordan'' lasted longer).
* ''Series/MagnumPI'' for Creator/DonaldPBellisario.
* ''Series/{{Lost}}'' for Creator/JJAbrams (though he'd already written or co-written several films and this wasn't his first series, having previously co-created ''Series/{{Felicity}}'' and created ''Series/{{Alias}}'').

* ''Series/DoubleDare1986'' for Marc Summers and Creator/{{Nickelodeon}}.

* ''Series/HRPufnstuf'' for Creator/SidAndMartyKrofft.
* ''Series/HouseOfCards'' for Creator/{{Netflix}} as a provider of original programming.

* ''Series/GameOfThrones'' for David Benioff and DB Weiss. Benioff was a prolific author and screenwriter and was probably best known for his screenplay to ''Film/{{Troy}}'', which while very successful hasn't made a fraction of ''Game of Thrones'' cultural impact. Weiss was also and author and screenwriter, but didn't have much to his resume at the time of the show's launch.
* ''Series/PushingDaisies'' for Bryan Fuller.
* ''Series/TheXFiles'' for Chris Carter. It also gave a start for Vince Gilligan and Michelle [=MacLaren=] (both on ''Series/BreakingBad'').

** ''TabletopGame/{{Pathfinder}}'', a derivative of the ''TabletopGame/DungeonsAndDragons'' 3.5 edition [=OGL=], for Paizo Publishing.
* While ''TabletopGame/{{Warhammer}}'' made Creator/GamesWorkshop popular enough to begin their own gaming system, ''TabletopGame/{{Warhammer 40000}}'' and ''VideoGame/DawnOfWar'', the strategy game based off it, would be what eventually put them on the map.
** ''TabletopGame/DarkHeresy'' and ''TabletopGame/RogueTrader'' for Creator/FantasyFlightGames in the TabletopRPG market, though they were already well-established as a BoardGame company beforehand.
* ''TabletopGame/VampireTheMasquerade'' for WhiteWolf.
* Though already known as a WarGaming company at the time, Game Designers' Workshop is better known today for its first foray into the TabletopRPG market, a little SpaceOpera game called ''TabletopGame/{{Traveller}}''.

* ''Theatre/JosephAndTheAmazingTechnicolorDreamcoat'' for Creator/AndrewLloydWebber.
* ''Tancredi'' for GioachinoRossini.
* ''Nabucco'' for GiuseppeVerdi.
* Rodgers and Hart made their breakthrough with ''Garrick Gaieties'', a 1925 revue that began as a benefit concert put on to furnish the Theater Guild's new home.
* ''Rienzi'' was Creator/RichardWagner's third opera and the first to be produced to success. Wagner later disowned it, however.
* ''Theatre/LeCirqueReinvente'' for Creator/CirqueDuSoleil. In hindsight, this show (the company's third) has a lot of EarlyInstallmentWeirdness, being conceptually simple compared to what followed, but it was their first show to tour beyond Canada and served as an introduction to the contemporary circus genre for U.S. audiences who mostly knew only the (at the time) fairly stale traditional style performed by Ringling Bros. and the like.
* ''Theatre/{{Cabaret}}'' for John Kander and Fred Ebb, and Harold Prince as a director. (Prince had been previously involved with the hit shows ''Theatre/ThePajamaGame'', ''Theatre/DamnYankees'', ''Theatre/WestSideStory'', ''Theatre/AFunnyThingHappenedOnTheWayToTheForum'' and ''Theatre/FiddlerOnTheRoof'', but only on the producing side.)
* ''Theatre/{{Brigadoon}}'' for Alan Jay Lerner and Frederick Loewe.
* Jerome Kern's songs for the 1914 musical ''The Girl from Utah'' moved him into the top tier of Broadway songwriters. Ironically, he wasn't the principal songwriter, which he had been on two less successful previous musicals, though a new MedleyOverture was devoted to his interpolated songs.
* ''Theatre/PeterGrimes'' for Benjamin Britten.
* Agnes de Mille had her first major success on the ballet stage with ''Rodeo'', and shortly thereafter made the breakthrough in musical theatre which had previously eluded her with ''Theatre/{{Oklahoma}}''.
* ''Manon Lescaut'' for Music/GiacomoPuccini.
* ''Theatre/BeyondTheHorizon'' for Creator/EugeneONeill.
* ''Theatre/AllMySons'' for Creator/ArthurMiller.
* ''Theatre/{{Oklahoma}}'' for Creator/RodgersAndHammerstein. The two writers were known independently beforehand for productions such as ''Theatre/ShowBoat'' (for Hammerstein) and ''Theatre/AConnecticutYankee'' (for Rodgers), then ''Oklahoma!'' ensured that the two creators would be inseparable in public knowledge from then on.
* ''Theatre/WestSideStory'' for Creator/StephenSondheim.
* ''Theatre/OnTheTown'' established the Broadway careers of Creator/ComdenAndGreen and Creator/JeromeRobbins, and could have done the same for Music/LeonardBernstein if his mentor Serge Koussevitzky had not convinced him to not dedicate his career to musicals--though this didn't stop him from composing several more.
* ''Theatre/SeventeenSeventySix'' for Peter Stone.

* ''VideoGame/DonkeyKong'' for Creator/{{Nintendo}} (and Creator/ShigeruMiyamoto). ''[[VideoGame/SuperMarioBros1 Super Mario Bros.]]'' would later be their breakthrough in the console games business, and due to some legal issues concerning ''Donkey Kong'', ''Super Mario Bros.'' tends to be considered their breakthrough by the company itself.
* ''VideoGame/DonkeyKongCountry1'' for Creator/{{Rare}} (as a second-party developer before they were bought by Microsoft).
* ''[[VideoGame/FireEmblemAkaneia Fire Emblem: The Dark Dragon and the Sword of Light]]'' for Intelligent Systems in Japan, ''VideoGame/SuperMetroid'' worldwide.

* ''VideoGame/HaloCombatEvolved'' for {{Creator/Bungie}} (and for [[Creator/MicrosoftStudios Microsoft's gaming division]]). Bungie did make several games before, most notably the ''VideoGame/{{Marathon}}'' series, but didn't achieve mainstream popularity before ''Franchise/{{Halo}}''.

[[folder: Other Publishers and Developers ]]

* Creator/{{Sega}} had a couple of different breakthroughs in different regions:
** ''Alex Kidd In Miracle World'' became a breakout hit in Europe, Australia and Brazil, where the Master System might even have outsold the NES.
** ''VideoGame/{{Sonic the Hedgehog|1}}'' made Sega popular in the US and was the title that was most often packaged with the UsefulNotes/SegaGenesis.
** In its native Japan, it was ''VideoGame/VirtuaFighter'', as it essentially launched the "3D arena fighter" genre, and its UsefulNotes/SegaSaturn port helped sell consoles there.
* ''VideoGame/HalfLife1'' for Creator/ValveSoftware.
* ''VideoGame/FinalFantasyI'' for [[Creator/SquareEnix Square]]. It was originally titled as such because [[SwanSong it was thought the company would go under after making the game]], but its [[SleeperHit surprise success]] kickstarted one of the longest-running series in video games.
** ''VideoGame/FinalFantasyVII'' was even more of a breakthrough, since that game took the ''Franchise/FinalFantasy'' franchise from popular-but-cult to international [[EasternRPG JRPG]] phenomenon (it was the first installment released in Europe, as the series had been virtually unknown in that territory up until that point). ''FFVII'' was also the breakthrough of character designer Creator/TetsuyaNomura.
* ''VideoGame/DragonQuestI'' for [[Creator/SquareEnix Enix]], the [[EasternRPG JRPG]] [[Creator/SquareEnix juggernaut's]] other half.
* ''VideoGame/WarcraftOrcsAndHumans'' for Creator/BlizzardEntertainment. You could make an argument for ''VideoGame/WorldOfWarcraft'', as well.
** Rather Starcraft. Long before WoW they were the AAA studio.
* ''VideoGame/{{Bejeweled}}'' for Creator/PopCapGames.
* ''VideoGame/{{Spyro the Dragon|1998}}'' for Creator/InsomniacGames.
* ''VideoGame/DisgaeaHourOfDarkness'' for Creator/NipponIchi Software.

** ''VideoGame/MegaManZero'' for Inti Creates, a studio created by former Capcom employees.
* ''VideoGame/{{Rayman}}'' for Creator/{{Ubisoft}} (and Michel Ancel).

* ''VideoGame/ViewtifulJoe'' for Creator/CloverStudios.

* ''VideoGame/{{Persona}}'' for Creator/{{Atlus}} in Japan, ''VideoGame/{{Persona 3}}'' worldwide.
* ''VideoGame/{{Contra}}'' for Creator/{{Konami}} on home consoles, its fame owed mainly to [[KonamiCode a certain cheat code]] in the NES version. ''VideoGame/{{Castlevania|I}}'' was a cult hit at the time, and [[Franchise/{{Castlevania}} the franchise]] never became super-popular until long after ''Contra.''
* ''VideoGame/{{Gex}}'' for Crystal Dynamics.
* ''VideoGame/TombRaider'' for Eidos Interactive.
* ''VideoGame/{{Pitfall}}'' for Creator/{{Activision}} in the UsefulNotes/{{Atari 2600}} era, and ''VideoGame/TonyHawksProSkater'' in the UsefulNotes/PlayStation era. ''VideoGame/CallOfDuty'' provided the company with yet another breakthrough.

* ''VisualNovel/FateStayNight'' for Creator/TypeMoon.
* ''VideoGame/ManiacMansion'' for Creator/LucasArts.

* ''WebVideo/TheNostalgiaCritic'' for Creator/DougWalker. First, the ''Film/BatmanAndRobin'' review made such a great impression on the internet, majorly thanks to the [[BerserkButton Bat Credit Card]], but these days, Doug kinda regretted that he could've done better for the review. The one review that solidifies this trope and the time when Doug got the best firm of balance of funny and thoughtful review would be the ''WesternAnimation/TomAndJerryTheMovie'' review.

* ''WesternAnimation/LooneyTunes'' and ''WesternAnimation/MerrieMelodies'':
** WesternAnimation/PorkyPig, introduced in 1935's "I Haven't Got a Hat," was their breakthrough star. Incidentally, Porky wasn't the main star of this film: the twin dog duo of Ham and Ex (who sing the title theme), were earmarked as the future stars of Warner Bros. cartoons.
** WesternAnimation/BugsBunny and Elmer Fudd: "A Wild Hare," released in 1940. Earlier cartoons had templates of both characters, but this was the first film to feature official versions of the iconic cartoon stars.
** Daffy Duck: "Porky's Duck Hunt" from 1937, in which he was a supporting character who drove Porky Pig nuts.
** Sylvester the Cat: Although his first film was "Life With Feathers" (where a suicidal bird tries to get eaten but the cat refusing because he thinks he's poison), it was the puddy tat's pairing with a certain yellow, blue-eyed canary the Tweety Bird, in "Tweetie Pie" that made our hapless, lisping black-and-white cat a star.
** Foghorn Leghorn: The loud-mouthed rooster's breakthrough was "Walky Talky Hawky."
** Tex Avery: his first big hit was his 6th short "I Love to Singa" (1936).
