->''"Yeah, well, I'm gonna go build my '''own''' theme park! With blackjack! And hookers! In fact, forget the park!"''
--> -- '''Bender''', ''WesternAnimation/{{Futurama}}''

A character or characters are disgruntled with the way a certain organization or group is run, and (usually after getting kicked out) decide that they will not just start their own, but it'll be ''better'' than the original. Generally either ends with the new organization actually being better or, alternately, failing miserably as Main/AnAesop about how some things are harder than they look.

TheMoralSubstitute is a SubTrope wherein the disgruntlement is (mainly) values-based.

Starting your own with friends or allies (however loose) will often result in an example of WeAreStrugglingTogether.


[[folder:Anime and Manga]]
* One ''Manga/DetectiveConan'' episode, "Computer Murder Case," involves a TearJerker failed example: [[spoiler:The SympatheticMurderer once worked for the AssholeVictim CorruptCorporateExecutive before eventually invoking this with a friend. Sadly, their new business was soon ruined by the victim, which also drove the friend to suicide. And to add insult to injury, the murderer then had no choice but to return to working for the victim, this time in a much lower position -- all while having to endure the latter's SpeakIllOfTheDead taunts about the friend on top of it. Understandably, the murderer finally snapped and decided to avenge his friend.]]
* In, ''LightNovel/BokuWaTomodachiGaSukunai'', Yozora starts the Neighbors Club as a club where people without friends could learn to make friends. Unfortunately, because LonersAreFreaks, the only people they get are other weirdos, and they more or less end up LonelyTogether.
* This is Haruhi's motivation for starting the SOS Brigade in ''LightNovel/HaruhiSuzumiya'' after she joins ''every single club'' at the school and quits after she gets bored.
** Played very straight by being the direct cause of the plot in ''Boredom''.
* Lelouch, the Main/MagnificentBastard main character of ''Anime/CodeGeass'', starts the Order of the Black Knights after the existing LaResistance proves its incompetence by getting decimated in a single episode. He later upgrades that into declaring his intent to start a new ''country''. Though in the end he gives up on the idea and switches to taking over the existing one, [[spoiler: after the new country is founded. (Without him.) And the new, much more successful, alliance of nations is founded. (With him.) Because his old organisation kicked him out. With guns. So, that's twice. Three times?]]
* After having helped save the world at the end of the ''Anime/{{Pokemon 2000}}'' movie, the Team Rocket trio have this discussion amongst themselves:
-->'''Jessie:''' So then we're not bad!
-->'''James:''' That's good!
-->'''Meowth:''' But what if the boss finds out?
-->'''James:''' That's bad.
-->'''Jessie:''' We'll start our own team!
-->'''James:''' That's good!
-->'''Meowth:''' But we got no money!
-->'''James:''' That's bad.
-->'''Jessie:''' Then we'll just steal some!
-->'''James:''' That's good! Or is that bad?
** Team Rocket also threaten to do this in a later episode, when they find their memberships have expired. It is quickly pointed out they can just reapply.
* This is the premise of the manga ''ComicBook/GothicSports'', where, motivated by the fact that they simply would never see any play in their school's normal soccer team, a few girls (with two guys...) get together and start their own team for the school.
* Ryuusuke and Eiji of ''[[Manga/{{BECK}} BECK: Mongolian Chop Squad]]'' initially play in the same band, Serial Mama, until personal differences and a missed opportunity with a record producer drive them apart. Both find success with their respective bands: Eiji's Belle Ame is commercially-successful, backed by influential producer Ran; while Ryuusuke with BECK have a much longer arc of struggles before gaining world-wide recognition.
* In ''LightNovel/LoveChunibyoAndOtherDelusions'', Rikka forms her own school club, the "Far Eastern Magical Nap Association", which is more or less a legalized excuse to let her delusions run amuck with Yuuta, Kumin and Sanae tagging along, willing or not. Nanase-sensei approves the club as a social circle, only because she noticed Rikka's determination to see her dream come to life despite lacking the prerequisite five members. Then it becomes a full-fledged club once Shinka actually applies, [[spoiler:hinting to her past life as another deluded teen herself]].
* Z, the BigBad of ''Manga/OnePiece Film Z'' was once a member of the Navy, but got so fed up with their corruption that he left and formed his own private army. Problem? His methods are too extreme for even Admiral ''[[GeneralRipper Sakazuki]]''.
** In the main storyline, Trafalgar Law was once a member of the Don Quixote Pirates, even being prepared to become Doflamingo's right-hand man on the Heart seat. (Dolfamingo's top Co-Dragons have a PlayingCardMotifs). However, after Doflamingo killed the current Corazon, his own brother and Law's favorite person, Law broke away and eventually formed his own crew, the Heart Pirates, so he could eventually take revenge.
* Hoshi-no-Tsuji High and Middle School in ''Manga/MagicOfStella'' institutionalizes this trope, as it doesn't require a faculty advisor to start a JapaneseSchoolClub; a few student members and the appropriate paperwork already handles it. The series is about a club that make ''doujin games'', which would be unthinkable everywhere else.
* ''Anime/MobileSuitGundamIronBloodedOrphans'': The main characters are ChildSoldiers who serve as [[WeHaveReserves expendable cannon fodder]] for a {{PMC}} who use "Run away while using the brats as human shields" as Plan A...and Plans B, C, D, etc. Understandably, they have issues with this, so they decide to start their own...[[TurnedAgainstTheirMasters by killing off their bosses]] and taking over their facilities, changing the name from CGS to Tekkadan.
* This is implied of the Outdoor Activities Club in ''Manga/LaidBackCamp''. The Outdoor Activities Club was born of Chiaki and Aoi's desire to experience the outdoors at a much more relaxed pace than the athletically-focused Hiking Club.

[[folder:Comic Books]]
* In Ann Nocenti's final issue of her ''Comicbook/{{Daredevil}}'' run, ComicBook/TheKingpin decides that if he can't force newspapers to run or not run the stories he wants, he will start his own media empire.
-->'''Kingpin:''' What sells newspapers?
-->'''Underling:''' Crime... Tragedy... Violence...
-->'''Kingpin:''' Well then, we'll just have to start a war.
* This is how Creator/ImageComics came into being. Several artists who worked on most of Creator/MarvelComics's top-selling properties in the late 80's to early 90's, such as Creator/{{Todd McFarlane}}, Creator/RobLiefeld, and Creator/MarcSilvestri, were dissatisfied with how poorly they were treated, in particular not owning any of the properties they created while working under Marvel. In 1992, they all left Marvel to form their own company: Image Comics. Image itself would not own anything other than its name and logo, and published the comics while the creators retained ownership, an arrangement completely unheard of at the time. Image single-handedly revolutionized the comics industry, with ComicBook/{{Youngblood}}'s first issue being the all-time best selling independent comic at the time of its release. At the height of its success, Image actually beat out D.C. in sales, forcing them to take drastic measures like [[ComicBook/TheDeathOfSuperman killing off Superman]] (albeit temporarily) and [[ComicBook/{{Knightfall}} crippling Batman]] in order to keep up with them.
* In Creator/GregRucka's 2011 run, Comicbook/ThePunisher takes on The Exchange, a bunch of former members of other various criminal organizations in the Marvel universe who decided to start their own organization.
* This trope seems to be [[IronMan Tony Stark's]] standard reaction whenever he loses control of Stark International.
* An old strip in ComicBook/TheDandy had a pair of eliminated wrestling champions who are kicked out for [[CheatersNeverProsper cheating]]. They decide to start a new wrestling league where everyone is allowed and no one gets eliminated.
* When the Franchise/JusticeLeagueOfAmerica wouldn't let Franchise/{{Batman}} interfere in international politics by arresting a supervillain dictator, he quit and formed [[ComicBook/BatmanAndTheOutsiders The Outsiders]].
-->''I've had enough of your two-bit Justice League! From now on, these are my new partners!''
-->--''[[http://media.comicvine.com/uploads/6/67397/2755085-01_super.jpg Batman And The Outsiders #1]]''

[[folder:Fan Works]]
* This is what gets the ball rolling in the pro wrestling story, ''A Ring Of Their Own''. [[Wrestling/LisaMarieVaron Victoria]] gets fed up with the state of women's wrestling and after conveniently winning $20 million in the lottery, starts her own promotion, the FWF.
* In ''[[https://www.fanfiction.net/s/8761623/5/Your-Father Your Father]]'', [[WesternAnimation/RiseOfTheGuardians Jack]] and a number of other cold-based mythological beings, tired of being left out of Christmas parties and such, started celebrating Christmas together a few decades ago.
* ''WebVideo/YuGiOhTheAbridgedSeries'' uses this as an homage to both the ''Futurama'' joke and the ''Fosters'' joke.
-->'''Kaiba:''' C'mon, Mokuba. We're going to have our own tournament. With blackjack. And hookers. In fact, forget the tournament.\\\
'''Dartz:''' We'll have our own evil council, and ours will be much better. And we'll have pizza! Pizza is better than tacos.
* [[https://www.fanfiction.net/s/12714427/4/Up-Your-s-Dumbles In this chapter]] of ''Literature/HarryPotter'' fanfic "Up Your's Dumbles", Fudge and Umbridge are informed that the Daily Prophet's new major stockholder prohibited them from publishing lies and Umbridge starts thinking it's time the Ministry starts their own newspaper. She hopes the Malfoys will support the idea.
* A major turning point in ''Fanfic/TheNewAdventuresOfInvaderZim'' comes in Episode 17, when [[spoiler: the Tallest tell Zim the truth of his mission and abandon him on Earth. [[EvilMentor Norlock]] then channels Zim's rage over this into going rogue, with plans of creating an empire of his own and using it to take revenge]].

* ''Film/{{Accepted}}'' is about some kids who couldn't get into any college starting their own.
* In the movie ''BringItOn Again'' the main character starts her own cheer squad to spite the [[AlphaBitch snobby head cheerleader]].
* One of the jokes in ''Film/EuroTrip'' about the [[RidiculousExchangeRates Bratislavan exchange rate]] involves Scott tossing a small coin to a hotel employee, who then quits and announces that he intends to buy his own fancy hotel with the coin.
* ''Film/JerryMaguire'' starts off with Jerry becoming disillusioned with the way the sports agency operates and he is subsequently fired. He decides to start his own agency and the rest of the movie follows his struggle to keep the business afloat while still maintaining his new principles.
* In ''Film/LittleGiants'', after linebacker Becky isn't picked to join Coach (and uncle) Kevin O'Shea's pee-wee football team solely because she's a girl (and despite that she's probably the best player at tryouts), she starts her own team, naming her dad (Kevin's brother Danny) as coach. Danny goes along to spite the way his brother has treated him all his life.
* ''Film/MontyPythonsLifeOfBrian'' has several subversive groups (Judean People's Front, People's Front of Judea, People's Popular Front, etc). It is implied that some of these came to be by breaking away from each other: the People's Front apparently consists of one "splitter."
* In ''Film/{{Nixon}}'', the President feels that he can't rely on the FBI or the CIA, so he institutes his own personal [[NoSuchAgency covert agency]], The White House Plumbers.
* ''Film/RevengeOfTheNerds'' centers around the titular {{nerd}}s creating their own fraternity chapter after being rejected by all the existing ones. Of course, being {{Hollywood Nerd}}s, the only one that will even give them a chance is the historically-black Lambda Lambda Lambda, due to a loophole which requires the frat to give them a trial period to start their own chapter. This does [[ScaryBlackMan come in handy]] [[BigDamnHeroes later on]] in the movie.
* Dewey in ''Film/SchoolOfRock'' threatens to do this after he's kicked out of his band, then falls into the perfect opportunity when he finds out some of the kids in his class are pretty good musicians.
* ''Film/{{Paranoia2013}}'': Wyatt used to work for Goddard before he quit to start his own company.
* Hans Gruber from ''Film/DieHard''. The leader of the terrorist organization he used to belong in even called a TV station to say he no longer works for them.
* ''WesternAnimation/{{Metegol}}'': [[spoiler:Unable to prevent El Grosso from destroying their town, the townspeople merely start another town elsewhere]].
* The BigBad from ''Film/TrueLies'' started the Crimson Jihad terrorist organisation after he felt that the other terrorist networks he worked for weren't extreme enough for him. His plan involves holding the United States to ransom with nuclear weapons.

* We have this trope to thank for both ''Literature/TheLordOfTheRings'' and ''Literature/TheChroniclesOfNarnia''. Creator/JRRTolkien and Creator/CSLewis, good friends in college and both big fans of classic mythology, both became frustrated that no one was writing those kinds of stories anymore. Finally they both agreed that they should write those stories themselves.
* In ''Literature/ParadiseLost'', when all the demons are debating what to do next, Belial suggests that they could just apologize. Mammon, being the JerkAss that he is, shoots that down, and then suggests that they make their ''own'' heaven, although blackjack and hookers aren't mentioned (but you know it would have them).
* In the realm of mystery fiction, similar stories underlie the creation of both Chesterton's ''Literature/FatherBrown'' and Creator/IsaacAsimov's ''Literature/BlackWidowers''.
* When ''Literature/TheBabysittersClub'' put [[ButtMonkey Mallory]] through a ridiculous series of training exercises in order to make her prove herself worthy of joining, she calls them out on their crap and starts her own club with her new best friend Jessi. It doesn't last, since the sitters eventually figure out that they were in fact acting like bitches and invite both girls to join the club.
* ''Literature/TwentyThousandLeaguesUnderTheSea'': Captain Nemoís BackStory is not fully revealed in this novel, but [[ButtMonkey He declares he has lost all his family because of ]] TheEmpire, [[{{Angst}} and the world continued like every other day]]. A lesser man would be just [[MaddenIntoMisanthropy Maddened Into Misanthropy]] and cut all ties with society. Captain Nemo [[StartMyOwn starts his own society]] recruiting [[MaddenIntoMisanthropy men who hate]] TheEmpire, training them to build and tripulate [[CoolShip the Nautilus]], [[ConLang creating their own language]], [[FromMyOwnPersonalGarden obtaining all his resources from the sea and none from shore]], [[EgoPolis reclaiming the South Pole]], [[YourTerroristsAreOurFreedomFighters financing the Cretan rebellion and converting themselves]] into a NGOSuperpower.
-->''"if I can trust my hunches, if I truly understand the captain's way of life, his Nautilus isn't simply a ship. It's meant to be a refuge for people like its commander, people who have severed all ties with the shore."''
* Happens a couple times in ''Literature/WarriorCats'':
** Some remnants of [=BloodClan=] decide to make their own Clan... in Ravenpaw and Barley's barn.
** Sol, [[spoiler:some time after parting ways with [=SkyClan=]]], attempts to form his own group in an abandoned Twoleg nest.
* In Jean Merrill's ''The Toothpaste Millionaire'' ''sixth-grader'' Rufus Mayflower responds to the high cost of store-bought toothpaste by starting his own toothpaste company with the help of his best friend.
* In Erwin Strauss's [[KeepCirculatingTheTapes out-of-print]] book ''How To Start Your Own Country'', he details ''how'' to start your own country.

[[folder:Live Action TV]]
* An episode of ''Series/AreYouBeingServed'' had the regular staff getting into a disagreement with the cafeteria staff. The cafeteria staff walks out and the regular staff are determined to do a better job than the cafeteria staff. They do - but only by sneaking out and getting expensive take-out food. Realizing that they were working extra-hard and spending themselves into a hole, they gave in and apologized.
* A StoryArc of ''Series/TheOfficeUS'' focused on Michael Scott quitting Dunder-Mifflin to start the Michael Scott Paper Company. By the second episode of the arc he was at it again: "I should leave them and start my own paper company. That'll show them." Either he's in some sort of feedback loop or it's a writer's [[LampshadeHanging lampshade]].
* Pretty much the overarching plot of the short-lived Wall Street drama ''{{Bull}}'': A group of young turks break away from the stockbroking firm they work for and make their own. It's not always smooth sailing, of course, which provides the drama of the series.
* ''Series/{{Smallville}}'' episode "Pandora" has [[spoiler: Future]] Chloe take Lois to Watchtower. She responds with this line:
--> '''Lois:''' Hey, Chloe? Remember when we were ten and I kicked you out of my clubhouse for spilling soda and you said you'd just build a cooler one? You win.
** Also, at the end of Season 1, when Lionel Luthor decided to shut down Luthorcorp's fertilizer plant in Smallville, [[ComicBook/LexLuthor Lex]] started Lexcorp in retaliation. Then it was revealed [[MagnificentBastard Lionel]] had planned all along to give Lex a little taste of independence before taking everything from him.
* This is what happens at the end of season three of ''Series/MadMen'' when Sterling Cooper becomes Sterling Cooper Draper Pryce, in order for the partners to avoid yet another merger. It starts in [[CrowningMomentOfAwesome an extremely awesome fashion]] too.
* An episode of ''Series/SmartGuy'' had these sentiments. When the cost of a type of soda went up to over a dollar, [[TheSmartGuy T.J.]] began to create and sell his own soda for 30 cents.
* ''Series/{{Angel}}'': In season 4, Wesley, having been cast out of Angel Investigations, is shown to have formed his own operation with a new gang. [[WhatHappenedToTheMouse There's no mention of what happened to this gang]] after Wesley is accepted back.
* ''Series/ThePractice'': After Lindsay Dole's murder conviction had been overturned, she decided to start her own legal practice instead of resume her work at Donnell, Young, Dole and Frutt. Later on, Bobby Donnell left the firm to start another practice and the firm was renamed Young, Frutt and Berlutti. Later on, when Alan Shore and Sally Heep were fired from Young, Frutt and Berlutti, Sally suggested to Alan the idea of starting their own practice but he rejected the idea. After Alan's successful lawsuit for wrongful termination of employment, Jimmy left the firm to start a new practice.
* ''Series/BostonLegal'': Jerry Espenson, a former associate of Crane, Poole and Schmidt, started his own practice after being fired for his reaction about not being named a partner. Despite having a good success, he decided to return to his former employers and was eventually named a partner.
* ''Caça Talentos'': This Brazilian show featured a talent agency named "Caça Talentos" (It can be translated to either "Talent Hunter" or "Talent Chaser") that was facing hard times. [[CorruptCorporateExecutive Silvana Carloff]], who owned 30% percent of the agency, was pressuring the major shareholder into selling it. One of her efforts consisted of starting her own talent agency to compete against his. "Caça Talentos" itself is another example since its founder started it in protest against his former boss' policies at Mundo Real Produções Artísticas.
* ''Series/PrincessPrincessD'': This live-action version of the manga ''Manga/PrincessPrincess'' featured a group of boys that, not satisfied with their all-boys school's [[WholesomeCrossdresser "Princesses"]], started their own group of "Princesses" known as "Dark princesses".
* One episode of ''Series/GetSmart'' dealt with ACB, the third spy network (with KAOS and CONTROL). They were founded by a KAOS agent who got passed over for promotion too often. He first tried to defect to CONTROL, who didn't want anything to do with him. This led him to starting his own group, and the episode revolves around Max and Siegfried having to team up to stop him.
* At the end of season 4 of ''Series/{{Chuck}}'' Chuck gets fired from the CIA and decides to start his own spy agency.
* At the beginning of ''Series/{{Outsourced}}'', Todd Dempsy considered starting his own novelties company rather than being transferred to India. All his boss did to make him accept going to India was remind him of a debt.

* In ''Series/{{Glee}}'', Sugar Motta has her rich father fund a second Glee Club within the same school after New Directions refuses to let her join. It doesn't change the fact that she can't sing to save her life.
* A common trope for the gang in ''Series/ItsAlwaysSunnyInPhiladelphia''. Among many examples, they started their own band after seeing Dee's ambiguously retarded boyfriend being a hit rapper. They also wanted to launch their own gasoline preservation to make money for the bar. [[CloudCuckoolander Charlie]] at some point, writes and directs his own musical. The list just goes on and on, including a desire to start their own police force, clothing line, Dennis running for comptroller, [[MisaimedMarketing an all-age drinking bar]], their own radio station, and so forth... it usually all descends into WeAreStrugglingTogether category.
* On ''Series/HowIMetYourMother'' Barney and Ted always wanted to start their own bar called Puzzles. On New Year's Eve 2011 they are outraged by the high cover charge at their usual bar and jokingly suggest that they should just start their own bar in Ted's apartment. The idea takes off and news of the bar goes viral. However, as more and more people show up, the party turns rowdy. As their costs due to damages and other expenses rise, they have to keep raising their prices until they are almost the same as the real bar and everyone leaves. Also they don't actually have a liquor license.

* In ''Series/{{Scrubs}}'' when the Janitor [[TeachHimAnger teaches Ted to be less]] of an ExtremeDoormat and stand up for himself, Ted disagrees with how the Janitor is running the Brain Trust and starts his own group called The Brain Bunch.
* ''Series/KickinIt'': Jack and Jerry were once in charge of Rudy's dojo. When Jack decided to ignore Jerry's ideas, Jerry opened his own dojo at Falafel Phil's. Also, Phil inspired Jerry by telling about his cousin, who used to work with Phil but decided to start his own because Phil refused to use ''real'' meat in the food he sold.
* In ''Series/BoardwalkEmpire'', after being snubbed in a deal, Gyp Rosetti takes over the [[ChokepointGeography strategic chokepoint]] of Tabor Heights to force Nucky into selling him liquor directly rather than have Arnold Rothstein acting as a middle man. Gyp soon recognizes the potential to supplant Nucky as Rothstein's main supplier and expand to the rest of New York and starts his own smuggling operation from there.
* At the end of season four of ''Series/BabylonFive'', Earth demand that Sheridan resign from his political post, [[spoiler: due to his role in rebelling against the Earth government. He willingly does so and is immediately made President of the new Alliance.]]
* In season 4 of ''Series/TheGoodWife'', all the fourth year associates are denied a previously promised partnership. They fake poaching clients for a while, hoping to scare the partners enough to get their promotion, but only manage to get Alicia promoted.[[spoiler: Ultimately Cary, Alicia, and the fourth year associates successfully found Florrick, Agos, and Associates.]]
* Logan starts his own secret society in ''Series/{{Zoey 101}}'', after [[spoiler: not being selected for the Silver Hammers]].
* Sam on ''Series/{{Cheers}}'' almost did this at the start of season eight, planning to buy an abandoned bar after getting fed up with Rebecca's bossiness. Robin Colcord talks him out of it, though, and steers him on the path he really wants: buying Cheers itself.
* Fayed from ''Series/TwentyFour'' season 5 formed his own terror group when his superior Assad decided to start peaceful negotiations with the West.
* In ''Series/TheBigBangTheory'', Sheldon does this just about any time he doesn't get his way. When his friends kick him out of their team for a science competition, he starts a new "team" (consisting of just himself). When they kick him out of their mobile app venture, he tries creating an app for Penny instead. When he fails to obtain a ticket to Comic-Con, he decides to start his own comic book convention. And so on...
* An episode of ''Series/{{Frasier}}'' had this happen with Frasier and Niles's wine club. Frasier is tapped to become the head, or "Corkmaster," of the group, only for Niles to run against him in an election. This naturally leads to fighting and arguing, at which point Martin comes down and reminds his sons that they used to do the same thing when playing as children. After he humiliates them in front of their friends ("Are you gonna let your brother play?"), Frasier and Niles decide to start their own wine society.
* ''Mosley''. After a speech denouncing the British government's inept response to the Great Depression, several other politicians offer an alliance with Oswald Mosley. However he prefers to form his own splinter party, which fails to gain the votes after he's laid up with flu during the election, unable to sway the populace with his legendary charisma. After this Mosley becomes increasingly ostracized from mainstream political life as his new party turns fascist.

* The entire DIY music-making ethic is based upon this trope. Musicians and bands who don't agree with the way major labels run the music industry will instead start their own labels and release their own records.
** Comedy rapper Devo Spice started the label FIDIM Interactive, "FIDIM" standing for "Fine, I'll Do It Myself".
* After being fired from Music/{{Metallica}} prior to the release of ''Kill 'Em All'', Dave Mustaine formed Music/{{Megadeth}}.
* Music/OzzyOsbourne started his own band after Music/BlackSabbath gave him the boot. His work there solidified him as a rock god. His replacement, Music/RonnieJamesDio did the same thing.
* Although Kim Deal formed Music/TheBreeders while she was still in Music/ThePixies, a major reason the band was started was that she didn't get to sing and/or write enough songs in her main band.
* Original Music/{{Weezer}} bassist Matt Sharp started the Rentals out of a desire to do his own take on early New Wave rock, and made it his full time job after butting heads with Rivers Cuomo. However, there couldn't have been ''too'' much animosity; Rivers co-wrote "My Head Is In The Sun" for ''Seven More Minutes'', the first Rentals album to be released after Matt Sharp left Weezer.
* The original Music/CannibalCorpse singer, Chris Barnes, started Music/SixFeetUnder in 1993 to do a more groovy style of death metal, and made it his full time job after he left his other band due to CreativeDifferences.
* Vocalists Tyler Carter and Michael Bohn were fired from Woe, Is Me in 2011 due to CreativeDifferences. In response, they founded Music/{{Issues}} the next year, which [[MorePopularSpinOff quickly became bigger than Woe, Is Me ever was]].
* Two examples come from the PowerMetal band Music/{{Helloween}}. The first being Kai Hansen's band Music/GammaRay, formed after he got fed up with [[SmallNameBigEgo Michael Kiske]] and quit, the second being ''Music/{{Masterplan}}'', a band formed by Uli Kusch and Roland Grapow after being kicked out of Helloween for trying to take the band in a DarkerAndEdgier direction.
* After leaving Music/AfterForever due to CreativeDifferences, Mark Jansen formed Music/{{Epica}}.
* Music/{{Girlschool}} started like this.
--> '''Kim [=McAuliffe=]:''' The reason we were all girls was we couldnít find any blokes who wanted to play with us! This was the natural thing to do.
* When Music/{{Rob Zombie}} was working on movies instead of writing music and touring, his guitarist Riggs and drummer Tempesta got tired of waiting on him and his band to start their own band, Scum of the Earth.
* Two groups grew out of the short-lived super group Azteca: After creative differences, founder and former [[Music/CarlosSantana Santana]] guitarist Neal Schon would break away and form the band Music/{{Journey}}, while bassist and former Sly & The Family Stone member Larry Graham took what was left of Azteca and formed Graham Central Station.
* Four out of six members of the original lineup of Swedish {{Horrible History|Metal}} PowerMetal band Music/{{Sabaton}} left to form the very similar[[note]]still mostly military history themed music, but MetalScream vocals instead of a basso growl[[/note]] Music/CivilWar after recording ''Carolus Rex'' in 2012, citing fatigue with Sabaton's touring schedule and a desire to have more of a role in songwriting. Sabaton frontman Joakim Brodén says they're still friends but admits things were tense at the time.
* In 1968, Creator/{{Motown}}'s star production team, Brian & Eddie Holland and Lamont Dozier, got into a financial dispute with Berry Gordy and when he didn't budge, left to form their own record label, Invictus/Hot Wax.

[[folder:Newspaper Comics]]
* In ''ComicStrip/CalvinAndHobbes'', Hobbes departed (or was booted out of) [[FunWithAcronyms G.R.O.S.S.]] and formed his own club, C.A.D. (Calvin's A Dope).
-->'''Calvin:''' ''That's'' not a name for a club!
* [[http://www.garfield.com/comics/vault.html?yr=2009&addr=090221 A cat hair left]] ''ComicStrip/{{Garfield}}'' to start his own cat. Upon getting caught by Jon's vacuum cleaner, he complained they hadn't told him about that in business school.

[[folder:Professional Wrestling]]
* Wrestling/LouThesz famously created the {{Wrestling/N|ationalWrestlingAlliance}}WA World International Championship belt with the long term goal of ''losing'' it to Wrestling/{{Rikidozan}} since it was clear a JWA bid for the World Heavyweight Champion belt would fail but Thesz wanted to keep his program in Japan going, since it was the most profitable of his career.
* This happened with other title belts, such as World Wrestling Associates creating a belt for Wrestling/FreddieBlassie when the rest of the NWA ignored his defeat of Édouard Carpentier, [[Wrestling/TedDiBiase Ted [=DiBiase=] (Sr.)]] creating the Million Dollar Belt, [[Wrestling/{{Tazz}} Taz]] creating the FTW Title, and Wrestling/ZackRyder creating the Internet Championship.
* This was the genesis of the of both the Wrestling/AmericanWrestlingAssociation (AWA) and the WWE (originally the World Wide Wrestling Federation (WWWF) and then the World Wrestling Federation (WWF)): In the early 1950s, Verne Gagne wanted to be the [[http://www.wrestling-titles.com/nwa/world/nwa-h.html NWA World Heavyweight Champion]]. The heads of the Wrestling/NationalWrestlingAlliance wanted to keep the belt on Wrestling/LouThesz, to the point where they wouldn't let Thesz wrestle Gagne anymore. Gagne and a couple of smaller promoters from the upper midwest broke away and formed the AWA in 1960, with Gagne as champion and boss. The WWWF formed under similar circumstances in the New England region in 1963: NWA champ "Nature Boy" Wrestling/BuddyRogers was reluctant to wrestle outside of the NE area. When the NWA had him lose the belt to Lou Thesz, he quit the NWA in protest, then joined with the regional promotion, Capitol Wrestling Corporation, to form the WWWF.
* Wrestling/AllJapanProWrestling and Wrestling/{{N|ewJapanProWrestling}}JPW both broke away from the JWA in 1970. [[Wrestling/{{FMW}} Frontier Martial Arts Wrestling]] was formed when the founders of both of those breakaways, Giant Baba and Wrestling/AntonioInoki, rejected Atsushi Onita's idea that "[[GarbageWrestler everything should be allowed in Puroresu]]" while SHIN FMW broke away(sort of) from regular FMW when Tarzan Gotoh was trying to become a draw without Atsushi Onita, W*ING broke away from FMW altogether and IWA Japan broke away from W*ING. The Wrestling/UniversalWrestlingFederation broke away from New Japan and Shooto broke away from that over [[Wrestling/SatoruSayama Tiger Mask]] feeling he wasn't getting paid enough. Super World Of Sports was formed when Megane Super hired All Japan wrestler Wrestling/GenichiroTenryu as a [[CelebrityEndorsement spokesperson]] and MS executive Hachiro Tanaka decided to use Tenryu as the foundation for his own pro wrestling promotion and Tenryu broke away from that to form WAR when Giant Baba wouldn't let him return to All Japan. Wrestling/ProWrestlingNOAH broke away from All Japan following the death of Giant Baba when Wrestling/MitsuharuMisawa felt his widow was restricting the roster too much. Wrestling/ProWrestlingZero1 broke away from New Japan when Inoki had Wrestling/NaoyaOgawa shoot on Wrestling/ShinyaHashimoto in an effort to force his retirement. Big Mouth Loud was formed when New Japan wrestler Wrestling/KatsuyoriShibata was told he could make more money as TheAce of a new promotion. Wrestle-1 broke away from All Japan when Wrestling/TheGreatMuta left the company in shame after TARU beat Super Hate so badly Hate had a stroke. Suffice to say, whenever an even moderately successful Japanese wrestler leaves a company they are associated with, with even a little publicity, fans expect a new one to be formed around them within a month.
* Lucha Libre Internacional broke away from [[Wrestling/{{CMLL}} EMLL]], taking on the Universal Wrestling Association as its athletic commission in 1975 when several key EMLL employees and investors discovered Salvador Lutteroth was grooming his son to take over the company. Wrestling/{{AAA}} broke away from EMLL in 1992 when Antonio Peña decided he wanted more freedom in booking. Ironically AAA's entry into the market was instrumental in killing the earlier breakaway group. Perros Del Mal Producciones was an [[InvokedTrope engineered]] breakaway from CMLL that [[GoneHorriblyWrong went horribly wrong]] and ended up working with AAA.
* For many years, the Memphis wrestling territory was run by promoter Nick Gulas. His head booker, Jerry Jarrett, entered an agreement with Gulas that he would eventually buy into a full partnership with Gulas. When Gulas screwed Jarrett over on the deal[[note]]He argued that the money Jarrett had already given him wasn't a down payment, but a holding fee giving Jarrett the right to buy in, in a now-expired time frame[[/note]]. A furious Jarrett then set about plans to start his own promotion, convincing Gulas' top talent (Wrestling/JerryLawler) and the announce team (Lance Russell and Dave Brown) to jump ship to his promotion. Several other Gulas' wrestlers (including "Soul Man" Rocky Johnson) caught wind of the plan and signed on. Within weeks, Jarrett's promotion had fully taken over the Memphis territory and Gulas' promotion had been shut down.[[note]]This also had the side effect of altering the local TV market, as Russell was the program director of Memphis' ABC affiliate and Brown was the weatherman there. Both men quit their jobs at WHBQ. Russell quit TV news entirely and joined Jarrett full time and Brown became the weather man at the NBC affiliate, WMC, where Jarrett's show now originated.[[/note]]
* After being fired from Wrestling/TheNationOfDomination by [[Wrestling/RonSimmons Faarooq]], [[Wrestling/BrianAdams Crush]] and Savio Vega formed their own groups "Disciples of Apocalypse" ([=DoA=]) and "Los Boricuas" respectively. Leading to The Gang Warz.
* Wrestling/{{ECW}} tapes were RF Video's main source of income, so when ECW went out of business in 2001, RF Video decided to make up for that loss of income by becoming a distributor of Wrestling/{{CZW}} media. Getting CZW / John Zandig to agree proved difficult however, but while watching All Pro Wrestling's second ''King Of Indies'' a little later that year, the guys at RF Video decide they wanted that instead and created Wrestling/RingOfHonor, based around previous KOI winner Wrestling/ChristopherDaniels, then most recent winner [[Wrestling/BryanDanielson American Dragon]] and runner up Wrestling/LowKi.
* Behind the scenes (mostly) example: Wrestling/JeffJarrett and [[Wrestling/VinceMcMahon Vince [=McMahon=]]] came to foster a mutual loathing for each other during Jeff's last Wrestling/{{WWE}} run, to the point that, when Wrestling/{{WCW}} went under, neither Jeff nor Vince were at all interested in working with the other -- Vince even announced, live and simulcast on ''[[Wrestling/{{WWERaw}} WWF Raw]]'' and ''Wrestling/WCWMondayNitro'', that Jeff was "G-double-O-double-N-double-E... GOONNEE!" So Jeff (with the help of his father, long-time promoter Jerry Jarrett) started his own ProfessionalWrestling promotion, Wrestling/{{TNA}}, which continues to thrive and gro--okay, which ''is still around'' today.
** On a side note, it should be noted that Jerry Jarrett is a long-time friend of the [=McMahon=] family; he personally delivered the wrestler who would become Wrestling/VladimirKozlov to the WWE. Also, Jeff Jarrett said that Vince was one of his biggest supporters during the death of his wife, so things have probably been patched up between the two.
** Having been pushed out of TNA by his major investor, Dixie Carter, Jeff is looked to repeat the feat by starting a new promotion, Global Force Wrestling. His quest to get GFW a television presence was met by many a setback, but the GFW brand nonetheless survived and eventually ended up supplanting the name TNA, as the major investors who replaced Carter brought Jeff Jarrett back, along with as many wrestlers associated with GFW as they could, and allowed them to permanently takeover "iMPACT", TNA's main television show. Though someone apparently got cold feet, as iMPACT quietly dropped the GFW branding after a while.
* His time in Wrestling/{{Evolution}} left a deep impression on Wrestling/RandyOrton. His ousting from the stable is largely considered his StartOfDarkness, and left him a strong hatred for Wrestling/TripleH and to a lesser extent, Wrestling/{{Batista}}. However, what shows Randy's inability to get over what happened in Evolution is his formation of his stable the Legacy, an obvious {{Expy}} of Evolution, but this time with Randy as the leader of the group and his quest to keep hold on the WWE Title paralleling Hunter's own quest to remain World Heavyweight Champion.
* After David Otunga schemed to get Wrestling/WadeBarrett kicked out of Wrestling/TheNexus and Wrestling/CMPunk installed as leader in his place, Barrett went to ''[=SmackDown=]'' and formed The Corre instead. And two other founding members of The Corre, Justin Gabriel and Heath Slater, walked out of Wrestling/TheNexus shortly after Barrett was deposed, unhappy with the way Punk was running things. Barrett is quick to point out that, unlike with The Nexus, he is not the leader of The Corre, as it's a gathering of equals; then again, he said that about The Nexus at first too. It took a few months, but Barrett's ItsAllAboutMe Attitude took over, and Gabriel and Slater promptly disbanded the group because of it.

[[folder: Tabletop Games]]
* The third party ''TabletopGame/DungeonsAndDragons 3.5'' {{sourcebook}} Untapped Potential was created by a group of Psionics fans in response to quality issues (Hint: It gets called "Complete Crud" for a reason) in the Complete Psionics first party sourcebook.
** The group responsible for that book, Dreamscarred Press, would later port over the psionics rules to TabletopGame/{{Pathfinder}}, along with [[SpiritualSuccessor spiritual successors]] to ''Magic of Incarnum'' and ''Tome of Battle''.
* ''TabletopGame/{{Pathfinder}}'' was created by D&D fans upset with the way that D&D's 4th edition turned out.
* The Pathfinder Adventure Path ''Kingmaker'' has the player characters start out as adventurers with the order secure a disputed border area and defend it against possible raiders or invaders from neighboring countries. Starting with the second adventure, they are making their own kingdom, with whatever additional features they want to!
** The rules from Kingmaker have been expanded and updated in the ''Ultimate Campaign'' rulebook, which also includes rules for building your own stronghold or running your own business or organization between adventurers.
* The Sons of Medusa chapter of SpaceMarines originated in a variation of this in ''TabletopGame/{{Warhammer40000}}''. A schism in the Adeptus Mechanicus spread to their chapter, resulting in several companies being exiled by the Iron Council. These proceeded to form their own chapter, one of the quite rare examples of a Space Marine chapter being founded without the consent of the High Lords of Terra. The Sons of Medusa were eventually recognized by both the Imperial government and the Iron Hands, but relations with the latter are chilly at best.

* In ''Theatre/TheBookOfMormon'', after the Mormon church closes down Kevin Price and Arnold Cunningham's mission for teaching ridiculous things to the Ugandans, they decide to continue the mission as their own sect of Latter-Day Saints, based on the Book of Arnold.

[[folder:Video Games]]
* ''Franchise/MassEffect'': Fed up with the bureaucratic crap at the Citadel, Garrus Vakarian traveled to [[WretchedHive Omega]] and formed a task force to antagonize the local criminals and warlords. He gained so much notoriety as "Archangel" that he forced an EnemyMine between the Blue Suns, Eclipse and Blood Pack, the three most powerful crime syndicates in the lawless Terminus Systems, and you find him just as they're gearing up to (try to) kill him.
* In ''VideoGame/TokyoXtremeRacer 3'', an ex-member of the racing team Unlimited forms a spinoff called Neo Limited.
* Laharl in ''VideoGame/Disgaea2CursedMemories'': "I don't even wanna be a part of this stupid world. I wouldn't stay if you begged me! Iíll go find a better world, with heaps of food! And cookies!"
* In ''VideoGame/{{Terranigma}}'', Marily from Loire works at Mme. Papilo's expensive boutique at low pay, but after Loire expands, you can help her start her own boutique that sells affordable clothing to the masses.
* If you manage to depose President Dave in ''Videogame/{{Fallout 3}}'', he'll leave with plans to start a new republic. Presumably one that's better and without people who get more votes than him.
** It does not go well. And if you provoke him while he's in a slump, he'll attack you.
** [[spoiler:The Enclave]] is also a form of this. After their main headquarters in the Pacific went boom, their chief intelligence in D.C. figured "fuck it" and reformed the remnants as his own democracy, rather than a fake democracy of royal presidents. Not that he's any better - [[spoiler:it's a low blow to call an AI an inhuman monster and someone who can't vote, but it logic bombs him to death.]]
* In ''VideoGame/FalloutNewVegas'', one of the options for the White Glove Society sidequest is to expose Mortimer as a cannibal. When he realizes that he won't be able to turn the rest of the society (who are reformed cannibals) back to the old ways, he declares that he'll build an even better society before running off.
* You can also build your own empire after disregarding both Legion and NCR and killing or subduing Mr. House.
* ''VideoGame/SuperMarioFusionRevival'' is an odd case. [=JudgeSpear=] long ago started a game he called ''Super Mario Fusion: Mushroom Kingdom Hearts'', a fan game focused on Mario visiting other dimensions. The influence of other developers made it mutate into ''VideoGame/MushroomKingdomFusion'', a game that took MegaCrossover UpToEleven. At one point in development communication between [=JudgeSpear=] and other developers was strained, so the game mutated further in that direction without his consent. When he became active again, ''VideoGame/MushroomKingdomFusion'' was so different from his original idea that he decided to leave it be and essentially used this trope ''on himself''.
* Has occurred in the VideoGame industry as well. While working at Creator/{{Atari}}, Jay Miner (having previously developed the [[UsefulNotes/{{Atari 2600}} 2600]] console and 800 computer) designed what would become the Amiga. Frustrated that Atari wouldn't produce it, he left, starting his own company, Hi-Toro, to build it. Hi-Toro went bankrupt, but Commodore bought them and the Amiga design, eventually manufacturing it themselves.
** A handful of Atari programmers during the [[CorruptCorporateExecutive Ray Kassar]] era were disgruntled that not only were they not getting credit for the games they created, but such information was treated as top secret. So they formed Creator/{{Activision}}, the world's first third-party gaming company, which upon creation gave credit to the programmer who created the game right on the game box and in television commercials.
** Creator/ElectronicArts was also founded for similar reasons not too long afterward. Now look at what they've become, although in hindsight, Activision is no different.
** tri-Ace, developers of the ''VideoGame/StarOcean'' series, was founded by the main programmer of ''VideoGame/TalesOfPhantasia'' who was frustrated with the ExecutiveMeddling that occurred with the games development.
** A sad case is when most of the old-school developers of Creator/BlizzardEntertainment (the people responsible for ''VideoGame/{{Warcraft}}'' one and two, ''VideoGame/{{Diablo}}'' and ''VideoGame/StarCraft'') left to form their own game studio, made the Diablo-clone ''VideoGame/HellgateLondon'', and bankrupted.
** In some cases, developers will leave a company and form their own due to ExecutiveMeddling, as in the tri-Ace example... only to find the new executives they installed are ''worse''. Ouch.
** Creator/TelltaleGames is another example, founded by ex-Creator/{{LucasArts}} employees after [=LucasArts=] all but abandoned the AdventureGame genre. Likewise, Tim Schafer and Ron Gilbert also left [=LucasArts=] to form Creator/DoubleFine.
** Ditto for Petroglyph Studios, formed by former Westwood employees after EA shut down Westwood.
** And the same thing can be said of [[http://www.rawthrills.com Raw Thrills]], which was formed in 2001 by Creator/EugeneJarvis after Creator/MidwayGames shut down their arcade division the year prior.
** After expressing more than a little disappointment with the lackluster UsefulNotes/NintendoGameCube release Wrestling/{{WWE}} WrestleMania X-8, Dave Wishnowski and a dedicated group began work on the PC-based wrestling title ''Pro Wrestling X''. Despite getting off to a strong start with an article in GameInformer magazine, then [[DevelopmentHell lengthy delays in development]] that threatened to send it to the ''VideoGame/DukeNukemForever'' pile of VaporWare, his company WishBoneX managed to start bearing tangible fruit with the concept in 2009, and the {{Prequel}} to the game, ''Pro Wrestling X: Uprising'' is finally slated for release between 4Q 2010 and 1Q 2011. Its success will apparently determine the viability of the original (expandable) concept game he'd originally intended back in 2001.
** The Creator/{{Sony}} UsefulNotes/PlayStation began life as a CD add-on for Creator/{{Nintendo}}'s [[UsefulNotes/SuperNintendoEntertainmentSystem Super NES]] console. However, when Nintendo backed out of their contract with Sony during development[[note]]because a buried clause would have given Sony perpetual rights to Nintendo's games[[/note]] and instead contracted with Philips for the add-on (which never materialized[[note]]but did spawn the infamous ''VideoGame/TheLegendOfZeldaCDiGames[[/note]]''), and dumped Sony in the most dickish way imaginable to Japanese businessmen (news of the change was withheld from Sony until the day of the CES, and then announced in front of an audience)[[note]]UsefulNotes/{{SNESCDROM}}[[/note]], Sony turned to Sega... only to be laughed at by the Sega execs, who claims that Sony knows nothing about the video games industry. This resulted in them turning the peripheral into a stand-alone console and entered the game market themselves, determined to teach Nintendo and Sega a lesson...which they did, displacing Nintendo's position at the top of the game industry with the UsefulNotes/PlayStation while contributing to the death of Sega's hardware business, and then retaining their stranglehold on the market with the UsefulNotes/PlayStation2, forcing Nintendo to [[TakeAThirdOption re-think gaming entirely]] in order to get back on top with the UsefulNotes/{{Wii}}. To be fair however, Sony's hands aren't clean in this. Sony had inserted a buried clause that would have resulted in Sony getting a very significant portion of the profits from all sales and complete control over licensing. Nintendo's CEO was furious when he found the clause and thought it was a great insult, and decided to fight fire with fire by humiliating Sony in public in return, which in hindsight turned out to be a bad idea.
** Similar to the above, Atari passed up an opportunity to distribute the UsefulNotes/NintendoEntertainmentSystem in the US, leaving Nintendo to market and distribute the NES on its own. You know what happened next. Many video game fans think that was for the best; while the [=NES=] would have come to North America a couple of years earlier, it's likely that Atari's mismanagement would've simply [[UsefulNotes/TheGreatVideoGameCrashOf1983 dragged Nintendo down with them]], dooming the entire video game industry to a Japan-only niche.
** Nintendo and Sony were so worried about large companies trying to co-opt their new consoles that they immediately rejected Microsoft's attempts to integrate online gaming into their console, so Microsoft [[UsefulNotes/XBox started their own console.]]
** Treasure Co., Ltd. is a developer founded by the former employees of {{Creator/Konami}}. They are known for their action games with innovative design. They partner with large game developers and working with licensed titles.
** Creator/VinDiesel was so tired of crappy licensed games based on his movies that he formed his own company, Tigon. Their first release was ''[[VideoGame/EscapeFromButcherBay Chronicles Of Riddick: Escape From Butcher Bay]]'', which most consider ''better'' than the movie it's licensed from.
** Following Creator/KeijiInafune quitting Creator/{{Capcom}} and forming his own company ''Comcept'', Capcom's cancellation of ''Mega Man Universe'' and ''VideoGame/MegaManLegends 3'' (the latter of which Inafune was heavily invested in and had wanted to make for years), and Capcom making no more ''Franchise/MegaMan'' games aside from the universally reviled ''VideoGame/RockmanXOver'', Inafune started a crowdfunding campaign for a new game, ''VideoGame/MightyNo9'', a new Mega Man game in all but name. [[CrowningMomentOfAwesome The Kickstarter for the game managed to raise its $900,000 goal in just over a day.]] The final sum raised? A whopping '''3.8 million US Dollars'''.
** Creator/MonolithSoft was founded by staff from [[Creator/SquareEnix Squaresoft]], notably the developers behind ''Videogame/{{Xenogears}}'' and ''Videogame/ChronoCross''. They would be financed by [[Creator/BandaiNamcoEntertainment Namco]], developing the ''Videogame/{{Xenosaga}}'' series under them, until they would be bought by Creator/{{Nintendo}} just after the Wii launched.
** After being sold to Microsoft from Nintendo, many of Creator/{{Rare}}'s employees had left the company over a period of a few years. Most of them have since banded together to form a new company called Playtonic Games. Their crowdfunded project ''VideoGame/YookaLaylee'' manged to hit their funding goal of £175,000 (US$270,041) in 38 minutes of being launched.
** Yu Suzuki was KickedUpstairs after the failure of the ''VideoGame/{{Shenmue}}'' series (which did cost Sega a lot financially). He left the company to start Ys Net, and after years of silence, has come forward to crowdsource for the next installment in the ''Shenmue'' series, much to the joy of the fandom.
** Creator/HideoKojima spent much of 2015 living an absolute hell since Creator/{{Konami}} cancelled ''VideoGame/SilentHills'', closed down his studio, Kojima Productions, removed his name from the cover of ''VideoGame/MetalGearSolidVThePhantomPain'', [[FromBadToWorse and even]] forbade him from accepting any awards the latter game won. As soon as his contract with Konami expired, he established his own independent game studio called...[[{{Irony}} Kojima Productions.]]
* The video game ''Jawbreaker'' was a case of this. It started out as a near-perfect port of ''VideoGame/PacMan'' for the UsefulNotes/Atari8BitComputers done by [[Creator/{{Sierra}} On-Line Systems]]. However once [[Creator/{{Atari}} Atari]] caught wind of it, rather than do the decent thing and license the program, they attempted to bully the programmer into giving them the game. As a result, ''Jawbreaker'' was released as its own game.
* Creator/JerseyJackPinball was started when game distributor Jack Guarnieri noticed his customers wanted expensive pinball games with deep rules and lots of mechanical toys, but Creator/SternPinball was moving towards simpler, low-budget tables. Jack decided the only solution was to start his own company and make the types of games that his buyers wanted.
* The Saikyo-ryu (lit. "Strongest Style") dojo started by ''Franchise/StreetFighter''[='=]s Dan Hibiki is his answer to being booted out of Gouken's Ansatsuken dojo for being too {{Revenge}}-obsessed with Sagat in his training.
* ''VideoGame/ChromaSquad'' starts out with the stunt actors for the Chroma Rangers walking off the set after getting fed up with the director's orders, and shortly thereafter starting a new studio in a warehouse owned by a relative of Chroma Blue's stuntperson.
* After being kicked out of nearly every guild, this is what motivates Karol to start one with Yuri in ''VideoGame/TalesOfVesperia.''
* It's been suggested that this trope was what inspired the inception of 2-D fighting game ''Beast's Fury'' by Evil Dog Productions; the leader of the development team, Ryhan Stevens, wanted the same fame and recognition (if not more) as ''VideoGame/{{Skullgirls}}'', which had enjoyed a very successful crowdfunding campaign. The game would later be cancelled in 2016 following a [[TroubledProduction contentious production]] and online acrimony towards ''Skullgirls'' fans, which left the reputations of Stevens and Evil Dog tarnished.
* A successful example of this trope: Eric Barone, having just graduated from college (computer science) decided to start making a game for fun and to practice his programming, he was a big fan of ''Videogame/HarvestMoon'', but considered the series to had gone downhill after ''Back to Nature'' and was unable to find something he thought was a suitable substitute for PC. He started to developing a ''Harvest Moon'' clone under the moniker [=ConcernedApe=], but the project gradually grew in scope, and four years later, ''Videogame/StardewValley'' was born.
* Creator/{{Natsume}} were the people that translated Marvelous main franchise, Bokujō Monogatari, under the name ''VideoGame/HarvestMoon''. However, Marvelous dropped Natsume and went with another company, Creator/XSEEDGames. However, since Natsume owns the rights to the Harvest Moon name, they decided to make their own and keep the series going. Bokujō Monogatari is now released under the name ''VideoGame/StoryOfSeasons''.

* ''WebAnimation/HomestarRunner'':
** In the ''WebAnimation/HomestarRunner'' game "Strong Badia the Free", Strong Bad gets everybody to secede from the King of Town's domain. He thinks everybody is going to join the now-autonomous Strong Badia, but instead they all go off and create their own countries. The rest of the game is him trying to convince everyone to band together to overthrow the King.
** In the Cheat Commandos episode, "Two Parter: Part One", after getting kicked out of the Cheat Commandos, Gunhaver, Silent Rip, and Crackotage get jobs at a pizza joint. When ''that'' doesn't work, they start their own restaurant...which doesn't turn out so well.
-->''"[[http://www.homestarrunner.com/ccdo7.html Kitchen Commandos, a really bad idea! It closed down after three months!]]"''
* ''Animation/{{Pucca}}'':
** Pucca and Ching wanted to visit Abyo and Garu's treehouse but Abyo wouldn't allow girls in. They built their own treehouse (which was better as expected of something built by Pucca) and wouldn't allow Garu and Abyo in.
** When Ling-Ling wouldn't allow Pucca and Ching to join the cheerleading squad, they started their own.
** Also, because Texas Lugie and Sloppy Sue didn't like the food served at the Goh Rong, they started a rival restaurant.

[[folder:Web Comics]]
* Trawn from ''Webcomic/ElectricWonderland'' started her independent newspaper out of discontent with futuristic {{Cyberspace}} news outlets placing decreased emphasis on presenting harsh truths to citizens.
* ''Webcomic/{{xkcd}}''
** In [[http://xkcd.com/927/ Standards]], two of the characters create a single unifying standard for the fourteen other (competing) standards. Instead of helping anything, there are now just 15 competing standards.
** In [[https://xkcd.com/703/ Honor Societies]], Cueball creates tautology club when he finds out it doesn't already exist.
* In ''Webcomic/KevinAndKell'', after R.L. ousts Kell as Herd Thinners C.E.O. and kills all of the changes Kell made to the company, Kell decides to open a competing company, with encouragement and backing from [[spoiler: The Rabbit Council, who see Kell's potential company as a way to eliminate their own competition - i.e. other prey species.]]
* In ''Webcomic/DanAndMabsFurryAdventures'', the three times we know about this happening two ended disastrously. Probably has something to do with the instigators of the first two being [[BlueAndOrangeMorality Creatures]].
** First, the Cubi Cyra decided to take over a city called Hishaan from the dragon M'Chek, but after she succeeded in killing him an unexpected energy surge [[http://www.missmab.com/Comics/Vol_1217.php destroyed the city]] and in the process kickstarted the genocidal Dragon/Cubi War that resulted in the deaths of almost all of Cyra's children save one and the complete destruction of many other clans.
** Second, the Demon Aliph Soulstealer/Dark Pegasus was snubbed for a position of leadership in his family's city of Zinvth, so he [[http://dmfa.katbox.net/comic/1552-at-least-he-is-ambitious/ tried to make his own]] and wound up accidentally creating the Undead race in the process when he [[http://dmfa.katbox.net/comic/1560-typos-the-oldest-mistake-in-the-book/ screwed up a spell]] and made his would-be puppets self-aware.
** The third was the direct result of the second, when the newly sentient Undead decided to make their own nation and founded Trik'na Island, where they can live in peace without fear of being killed on sight. It's actually very successful economically since its residents neither need to eat or sleep, but the living world is reluctant to deal with them.
* ''WebComic/TheOrderOfTheStick'' prequel volume that [[StartOfDarkness shows the backstory of Xykon and Redcloak and how they came to be villains]] shows us that Xykon, then a young sorcerer, once did this. As an apprentice to [[NamesToRunAwayFromReallyFast The Unholy Master]], Xykon was under consideration to be promoted to the NumberTwo position... but was [[PassedOverPromotion passed over]] in favor of ''both'' his FriendlyRival (and sometimes lover) Yydranna and [[TheCameo Keith Baker]]. (A real life FriendlyRival to the author of OOTS.) Furious at having Baker chosen over him, Xykon decided it was time to quit being an apprentice and go into business as a villain for himself.
* ''Webcomic/GuildedAge'': The effectiveness of the Gastonian Peacemakers was not lost on Harky, especially after the miserable defeat in B'ial Vezk, so in response he put forth a call to arms for a team of champions that would serve the World's Rebellion, one member from each race. It worked. Extremely well.

[[folder:Web Original]]
* Also, [[TheWikiRule Wikis]]. Many are started because they have focused subject matter, but many others are founded because Wiki/{{Wikipedia}}'s standards of notability and citation somehow exclude them, or they think there's something biased about it. For instance, Conservapedia was created by a group who decried Wikipedia's "evidence" and "objectivity", and made their own online encyclopedia with their ''own'' bias. [[Wiki/TVTropes This very wiki]] specializes in covering the tropes of popular culture. Since Wikia allows anyone that wants to start a Wiki to do so, this happens quite often with those who don't like the guidelines, procedures, etc., etc. of a particular wiki. It often doesn't end well, since most of these people are neither suited to be admins nor have the ability to gather followers to their new wiki. One of the most prominent examples (and far more successful than most) is the ''StarWars'' fandom's [[PunBasedTitle Wookieepedia]], which came about when Wikipedia purged a great many ''Star Wars'' articles as "non-notable". Copies of the purged articles were part of the core of Wookieepedia in its early days. Now Wookieepedia is the 5th-largest Wiki in existence.
* Happens online all the time, due to the relative ease of creating a website. If we listed all the examples we'd be here all day. However, two famous victims are Website/LiveJournal, which has a half-zillion clones at this point (all of them near-''perfect'' clones in fact, due to the site's open-source codebase), and Website/DeviantART, whose restrictive policies led to the creation of [=SheezyArt=] and later [[UsefulNotes/FurryFandom FurAffinity]]. In most such cases, the result is similar to the comedic examples in fiction, with so many people starting their own site that none of them have many users.
* At one point in its history, the ''Roleplay/GlobalGuardiansPBEMUniverse'' had a new referee who decided, without any consultation on the owners of the property, or with the other referees, that he was going to rewrite the history of the game world, and move the game to a new site out of the owner's control. When he was (justifiably) booted with extreme prejudice, he declared the old group lame and started up his own. It lasted about four months before folding.
* Happened with ''WebVideo/MisadventuresOfAwkwardBlackGirl''. Issa Rae, the creator, started the show because she was tired of the depiction of people like her as a SassyBlackWoman, a MagicalNegro, or a sexy vixen.
* SpaceBattlesDotCom birthed not one, but two, ''Questionable Questing'' and ''Sufficient Velocity''.
** QQ was created after one too many crackdowns and censures on the RolePlayingGame board, where some members found the site's rules against NSFW content too restrictive. A few got together and created a place with basically ''no'' rules against NSFW... ''anything'' so long as it was posted in the correct place.
** Due to some unpleasantness regarding an admin being '[[Film/BladeRunner retired]]', [[http://forums.sufficientvelocity.com/ Sufficient Velocity]] was spun-off, with many threads cloned or moved. Acted as an alpha site when SB reached capacity, then the users which had evacuated shuffled back when its problems were resolved at the eleventh hour. Is since better known for it's more... in-depth approach to site rules and moderation.[[labelnote:*]]With two of SV's three founders and owners being lawyers, the SV site rules and community compact are significantly more developed than most sites bother with. This is partly as a result of Athene's 'retirement' (as noted above), and partly to do with the fact that it was created by ''lawyers''. As such, SV has a four tier staff hierarchy, three different kinds of staff, and a democratically elected (by users) Community Council responsible for reviewing staff action. Whether this results in enlightened discussion, institutionalised oppression, or makes no difference whatsoever, is generally a matter of personal opinion.[[/labelnote]]

[[folder:Western Animation]]
* The above quote is from the ''WesternAnimation/{{Futurama}}'' episode "The Series Has Landed" after Bender is kicked out of Lunar Park, and later when Fry and Leela keep Bender out of the Apollo 11 lunar lander. The line has gone on to become a [[MemeticMutation popular meme]].
* In an episode of ''WesternAnimation/FostersHomeForImaginaryFriends'', Bloo is not allowed into a rock band called Pizza Party. So to spite them, he invents his own band called Taco Feista (because, he reasons, tacos are more exotic than pizza). Bloo's own band leaves him and so he forms ''another'' band, which is just himself in various costumes.
** In another episode, Bloo started his own foster home for imaginary friends, which was nothing more than a cardboard box.
* ''WesternAnimation/TheSimpsons''
** In "Homer the Great", the Stonecutters start the No Homers Society after they get disgruntled by Homer's attempts to do good in his position of power.
** In "$pringfield, or: How I Learned to Stop Worrying and Love Legalized Gambling", Bart is kicked out of Mr. Burns' casino for being underage. The Squeaky-Voiced Teen taunts him, saying "What are you going to do? Start your own casino? In your tree house? And get all your little friends to come? [[TemptingFate I'd like to see that!]]" [[GilliganCut Cut to the next scene]], where Bart is welcoming his friends into his tree house casino. "Well, he certainly showed me."
** In "Homer the Moe", when Moe's Tavern gets a hip makeover and the old customers are no longer welcome, Homer starts a "hunting lodge" in his garage ([[LoopholeAbuse he couldn't have a tavern there]]) where he and the old regulars hang out until Moe comes to his senses. They even went as far as taking part on regular hunting trips as all hunting lodges are required by law.
** In "Fear of Flying", when Homer was banned from Moe's the first time, Marge suggested he pretend the house was a bar, so he could spend every night at home. He responded he wasn't even going to dignify it with an answer.
** And yet again, in "Lisa the Vegetarian", when Homer is offended that Ned didn't invite him to his ''family'' reunion, Homer says he'll have his own barbecue and invite whomever he wants - "That'll show you!". However, Ned [[PolitenessJudo politely asks]] whether he can come and Homer says "Sure!" reflexively. D'oh!
** In "Lemon of Troy", this was the cause of Jebediah Springfield and Shelbyville Manhattan's split:
--->'''Shelbyville:''' I will not live in a town that robs the man of the right to marry his cousin.\\
'''Springfield:''' Then I will start my own town, based on abstinence, chastity and a flavorless mush I call root marm.
* An episode of ''WesternAnimation/{{Arthur}}'' revolves around the kids creating their own "[[Film/JamesBond James Hound]]" movie, since they're not old enough to see the actual PG-13 movie themselves. They eventually discover that all the outtakes are actually [[SoBadItsGood better than what they planned]].
** An earlier one involved Muffy getting fed up with Arthur's shabby clubhouse and leaving to start her own club, and Buster and Francine deciding to join her. Gradually, ''everyone'' abandons not only Arthur's never-been-official-anyway club, but each other's as well, until everyone is a one-person "club" of their own. Eventually they all realize how stupid it all turned out, and get back together.
** A later one involves Francine and a group of friends starting a band called U Stink, but Francine quits and starts her own band called We Stink with Arthur, Buster and George. Arthur and Buster end up getting mad at her and quitting, claiming they will form their own band and call it She Stinks. George doesn't mind staying, but Francine gives up.
* Similarly, in ''WesternAnimation/RocketPower'', the kids try to make their own movie and find it to be much harder than they were expecting.
** The kids, in response to a movie that they agreed was terrible, end up filming a movie. The episode ends with a younger group of kids deciding that the movie that was filmed by the original group [[BookEnds was also terrible, and set off to create their own film]].
* Creator/HannaBarbera's ''WesternAnimation/TheLittleRascals'':
** In "Beauty Queen for a Day", when Alfalfa won't let Darla into the He-Man Woman-Haters' Club, Darla threatens to organize a She-Woman Man-Haters' Club: "And there will be no '''''boys''''' allowed!"
** In "Big Top Rascals", the Rascals put on their own circus after being denied admission to a real circus. Darla had told the circus owner that she and the boys were tending the animals because they had no money for tickets.
* The male unicorn decides to build [[TheGreatFlood his own ark]] after missing Noah's on ''WesternAnimation/RobotChicken''. [[http://www.adultswim.com/video/?episodeID=8687905da0a1166b82131930b0001010]]
* In the ''WesternAnimation/CareBearsAdventuresInCareALot'' episode, "Whose Friend is Who?" a bit of a club war gets started because Cheer, Harmony, and Love-a-Lot reject Funshine and Oopsy's help in making a "project" with their human friend [=McKenna=]. So, with Grumpy, they make their own "project" and a subsequent club to go with it. The girls retaliate by forming their own club, and a montage of the two clubs one-upping each other in their projects ensues, with [=McKenna=] stuck in the middle, not wanting to pick a side. She eventually gets the two clubs to see how silly they're being by making a club with [[RobotBuddy Wingnut]], and calls them out when they band together to exclude her club.
* In ''WesternAnimation/FamilyGuy'', Peter is so jealous of Joe's home movie theater that he decides to build an addition onto his house to create an even bigger and better theater than Joe's. Of course, this plot is quickly forgotten once Peter digs up an Indian skull and the real plot of the episode starts.
* A ''WesternAnimation/LooneyTunes'' cartoon started with Daffy Duck as a janitor of an inn that belonged to Porky Pig. Daffy was feeling unappreciated and, when Porky tried to show his appreciation by giving him a new broom, Daffy decided to start his own inn. [[FailureIsTheOnlyOption Daffy's dishonest attempts to run his former employer out of business backfired.]] His last plan consisted of blowing up Porky's inn. [[spoiler: Daffy DID blow up Porky's inn, but accidentally revealed the presence of oil under it, allowing Porky to build an even better inn. To show Daffy he doesn't keep hard feelings, Porky hired him to work at the new inn... [[WhereItAllBegan as a janitor]].]]
* One episode of the ''ComicStrip/{{Dennis the Menace|US}}'' animated series portrayed Dennis and Margareth as business partners in a lemonade stand. Unsatisfied with her share of the profits, she started her own lemonade stand to compete against her now former business partner.
** Dennis and Joey grew so tired of working on Margareth's float for a Fourth of July parade (and of her bossiness) they declared independence from her and made their own float.
* A mock episode of ''WesternAnimation/{{Birdman}}'' retconned Murko the Marauder as a F.E.A.R. agent leaving to start his own criminal organization.
* One episode of ''WesternAnimation/TheMask'' featured a character named Celia N. Airtight. She was a top researcher at Wrapmaster Corporation until being fired for knowing too much about food preserving and then she started her own company named Putterware to compete against Wrapmaster. Not satisfied with selling more than her rival, she plotted to turn leftover food into monsters to destroy Wrapmaster.
* ''WesternAnimation/KingOfTheHill'' features Thatherton Fuels, a company founded by M.F. Thatherton, a former employee of Strickland Propane.
* ''WesternAnimation/TazMania'' episode "Francis Takes a Stand" featured Francis starting a lemonade stand. Taz opened another one across the street from Francis'. The only customer who ever appeared was a tax collector who, after buying a lemonade from Francis (and hating its taste), revealed himself a tax collector and took the money he gave Francis as payment for the lemonade.
* In ''WesternAnimation/CampLazlo'', Edward starts an "I Hate Lazlo" club, inviting everyone except, of course, Lazlo. He tells Lazlo to form his own club, the "Nothing Club", which Lazlo does. Soon everyone leaves Edward's club after finding it too boring (it's all about talking about how much they hate Lazlo, which only Edward does) and head over to Lazlo's.
* In an episode of ''WesternAnimation/{{Doug}}'', Patti was rejected from the Honkers baseball team, because she's a girl. As a result, she forms "Patti's Pulverizers", which consists of [[RagtagBunchOfMisfits players who were rejected by the Honkers]].
* [[WesternAnimation/SpongebobSquarepants Spongebob]] started his own "Pretty Patty" stand after being mocked for his idea by Mr. Krabs and Squidward. He ended up having 46,853 customers. Seeing how successful the stand was, Mr. Krabs traded Spongebob the Krusty Krab for it...right before all the customers starting experiencing colorful side effects to the patties and demanded a refund.
** [=SpongeBob=] also created his own Mermaid Man and Barnacle Boy movie when the big-budget movie starred muscle-bound actors instead of the elderly, retired heroes.
* ''WesternAnimation/MissionHill'' - when Andy and his friends are kept out of a hip new nightclub in their neighborhood, they retaliate by pretending to open a new club in an unlocked boiler room, and keep out all of the hip crowd who queue up at the door.
* ''WesternAnimation/TheCritic'': When Duke Phillips can't get the daughter of the assistant to one of his most expendable employees into The Rainbow's End Preschool:
--->'''Duke Phillips:''' I've never been so insulted!\\
'''Mr. Jordell:''' So what are you going to do, build your own preschool? Ha ha, your own preschool, I'd like to see that. (Chuckles)\\
''(Cut to: "Duke Phillips' Pre-school: Built on a Dare.")''
* ''WesternAnimation/IronManArmoredAdventures'': When Justin Hammer took over Stark International, Tony decided to create his own company. Pepper suggested he named it "Circuits Maximus" but Tony had already opted for [[AlliterativeName "Stark Solutions"]]. Both names count as MythologyGag since Tony Stark did start companies with both names in separate occasions he lost control of Stark International.
* ''WesternAnimation/{{Jem}}'': After Eric Raymond lost his half of Starlight Music, the Misfits needed another music company to promote their albums so Pizzazz asked her father to start one.
** In "[=KJEM=]", Jem took over a radio station so the previous owner wouldn't lose it to a former employee who had started his own radio station for not liking how his former boss ran things.
** Kimber (from Jem and the Holograms) and Stormer (from the Misfits) were feeling underappreciated and temporarily became a duo.
* ''WesternAnimation/NASCARRacers'': Megan temporarily left Fastex to start her own racing team.
* In the original ''Literature/{{Franklin}}'', there were a few of these: Franklin's "Turtle Trackers" group in "Franklin Wants a Badge," the various characters' secret clubs in "Franklin's Secret Club" and Franklin's "Turtle Point" in "Franklin's Birthday Party." In "Franklin, the Planner" on the ''Franklin and Friends'' spinoff, the kids all end up doing this, pairing off and starting their own floor plans for a new treefort when it doesn't seem like there's enough room to fit each of their own ideas in the original floor plan. The problem, of course, being that only ''one'' treefort can be built and they need something that satisfies everyone. It's Franklin who comes up with the idea for compromise, they can't all have ''everything'' they want in the treefort, but each of them can use their best idea and they'll put it all together.
* In the ''WesternAnimation/PhineasAndFerb'' episode "Hail Doofania!", Dr. Doofenshmirtz is frustrated that [[AlwaysSomeoneBetter his goody two-shoes little brother Roger]] got elected mayor of Danville, so he tries to build his own floating city in Danville Harbor. Doofania's civic anthem even boasts "[[EvilIsPetty It's founded on spite]]!"
* ''WesternAnimation/SofiaTheFirst'': In "Princess Adventure Club", Princess Zooey doesn't let Amber join the titular club and Amber retaliates by starting her own adventure club.
* In an episode of ''WesternAnimation/{{Daria}}'', after [[AlphaBitch Sandi]] tricked Quinn into volunteering to help set up the school dance, she grew frustrated over the fact that Quinn wouldn't take her advice. She decides to throw her own party with the rest of the Fashion Club. It doesn't go over very well though. Since it's the same night as the school dance, no one shows up except for Joey, Jamie and Jeffy, and they quickly leave as soon as they realize Quinn isn't coming.
* ''WesternAnimation/APupNamedScoobyDoo'': Lester Leonard left the Critter Getters to start his own monster-catching business.
* In ''WesternAnimation/HeyArnold'', Rhonda threw a party to which she only invited kids she deemed cool enough, Arnold himself making that list. Arnold quickly got bored of listening to Rhonda prattle on about her vacation in Europe and insulting his friends and left, rejoining with his friends and suggesting they throw their own party on the roof of the boarding house. One by one, the other "cool kids" leave Rhonda's party for Arnold's, realizing that the "geeks" are having more fun. Eventually, Rhonda gave up when everyone left, and she joined them all in the end. (Though she still was going to consider herself a cool kid).
* WesternAnimation/RockyAndBullwinkle: In one Fan Club segment, Boris is disgusted by the club oath and decides to form his own fan club.
* ''WesternAnimation/BeCoolScoobyDoo'': In "Doo Not Disturb", after Jack and Josh Stanley inherited the Good Sons Inn from their mother, Josh didn't want to run the place the same way he did and, unable to convince his brother to see things his way, forfeited his share and started a rival hotel named Castaway Resort Hotel. [[spoiler:In spite of his success, Josh still wanted the now renamed Good Son Inn to the point he dressed himself as his mother's ghost to scare away Jack's guests.]]

* Texas oil tycoon Clint Murchison, Jr. wanted to buy the then-flagging Washington Redskins in 1958, but he backed out of the deal after Redskins owner George Preston Marshall changed the terms that were unfavorable to him. As a result, Murchison formed the Dallas Cowboys in 1960, and the most-well known rivalry in NFL history was born.
** What's more, Murchinson purchased the rights to the Redskins' fight song, and the Skins must pay the Murchinson's heirs a royalty every time they play it!
* This is the state of boxing with four "main" sanctioning bodies (five if you count the IBO) they are:the W.B.O, I.B.F, W.B.C, and the W.B.A. This means that at any time there are four champions in any given weight class at any time. Becoming "the" champ is damn near impossible because of a set of convoluted rules that pretty much disqualifies boxers from holding all the belts at the same time. This, compounded with all of them being notoriously corrupt and numerous other organizations springing up almost daily, effectively make belts worthless.
* In March 1995, Tony George, head of the Indianapolis Motor Speedway (home of the Indy 500), announced the formation of the Indy Racing League (IRL), ostensibly to make open-wheel racing in America less Euro-centric and give more direct control of the sport to track owners. Oh, and the majority of the drivers at the Indianapolis 500 (25 out of 33) would now have to be from the IRL. The existing sanctioning body, CART, responded with a blanket boycott of all IRL races and scheduling the new US 500 to run at the same time as Indy. The split remained for thirteen years before the sport was reunified under the IRL banner. [[HoistByHisOwnPetard Ironically]], racing fans, confused and frustrated by the split, turned in droves to stock car racing and NASCAR.
* The American Basketball Association formed in 1967 to compete against the NBA, but was actually a long-term plan to merge its teams with the NBA, which happened (for some of them) in 1976.
* The founder and first president of the ABA went on to form the World Hockey Association in 1972, and was the most successful challenge to the NHL's dominance in North American hockey and helped bring down the NHL's reserve clause. The WHA administration refused to incorporate the reserve clause (which allowed a club to extend a player's contract by a year when it expired and do so indefinitely, effectively binding a player to one club for his entire career) and set a then-landmark $2.7 million salary for Bobby Hull. Though the league didn't survive the Seventies, several teams merged with the NHL.
* The NHL itself was the result of a long-running dispute in the predecessor National Hockey Association between Eddie Livingstone, principal owner of the Toronto Shamrocks and Toronto Blueshirts, and the other owners of the league (Montreal Canadiens, Montreal Wanderers, Ottawa Senators, and Quebec Bulldogs). The other owners realized the NHA's constitution meant they couldn't expel Livingstone, but they could vote to suspend the NHA (officially because too many of their players were overseas fighting in UsefulNotes/WorldWarI) and then form the National Hockey League where those owners could keep Livingstone out. Which is what they did in 1917.
* The NFL has been challenged by several rival leagues, among them include the American Football League, the United States Football League, and Wrestling/VinceMcMahon's XFL. The AFL was successful enough that it eventually merged with the NFL without losing any teams. The others... not so much (the USFL was successful enough in a few areas that the NFL later added expansion teams in those places, but the XFL was highly gimmick-driven and taken seriously by approximately nobody).
* Australian television magnate Kerry Packer attempted to buy UsefulNotes/{{Cricket}} broadcasting rights from the Australian Cricket Board in the 1970s, but they refused, so Packer formed World Series Cricket, signing many of the players from Australia, England and the West Indies.
* The genesis of the American Football League is a perfect example of this trope: In 1959, the National Football League had only twelve teams, had no interest in expansion and only one team - the then-Chicago Cardinals - was considered to be on the market. Texas oilman Lamar Hunt had a meeting with Cardinals general manager Walter Wolfner (husband of team owner Violet Bidwell) who basically blew Hunt off. Wolfner bragged that they had suitors from all over the country, mentioning groups from Denver, Houston and Minneapolis, so he really didn't need to deal with Hunt. As Hunt flew back to Dallas, he realized that if there were really that many parties trying to get into pro football, there was no reason they couldn't just start a new league. The eight-team AFL debuted a year later. The documentary ''Series/FullColorFootball'' has the story in greater detail.
* Similar to the Dallas Cowboys example, and also crossing over with CreateYourOwnVillain, when the Cleveland Browns fired Coach Paul Brown, who the team is ''named after,'' he joined the new AFL and formed the cross-state Cincinatti Bengals, who not only are the Browns' second biggest rival behind the Pittsburgh Steelers, but also will [[NeverLiveItDown never let Cleveland forget this]] by playing their home games at ''Paul Brown'' Stadium. It should be noted that, at the time of the Bengal's inception, Brown knew the AFL/NFL merger was a done deal and that the ensuing league realignment meant his new team would likely be placed in the same division as Cleveland.
* When the [[UsefulNotes/BritishFootyTeam English football team]] Wimbledon F.C. decided to relocate to Milton Keynes in 2002, a lot of fans were rather upset. In response, they formed their own club, AFC Wimbledon. In less than a decade, the new club had made it into the Football League, and in 2014, [[CrowningMomentOfAwesome they beat the relocated "Milton Keynes Dons" in a cup match]].
** In 2005, a group of Manchester United fans unhappy about Malcolm Glazer's takeover founded their own club, FC United of Manchester. FC United are, as of 2015-16, in the sixth tier of the league.
** A much older and more prominent example: when Everton were first founded, they played their home matches at Anfield. In 1892, after a dispute over rent, Everton left to go play at Goodison Park instead and Anfield's owner, John Houlding, decided to make his own team. He thus founded Liverpool F.C. with some of his old Everton friends, and one of English football's fiercest rivalries was born.
* When The Olympic Games decided to drop baseball and softball in 2005, the International Baseball Federation (IBAF) along with pro leagues from all over the world (including America's Major League Baseball and Japan's Nippon Professional Baseball) started their own large-scale international tournament, [[http://en.wikipedia.org/wiki/World_Baseball_Classic the World Baseball Classic.]]
* [[UsefulNotes/{{Basketball}} Pat Riley]] spent five years as the head coach of the New York Knicks, building his team into a gritty, grind-it-out playoff powerhouse. Known for their physical play and rough fouls, they made it to the NBA Finals in 1994, where it took the full seven games before the Houston Rockets defeated them. That, along with several other heartbreaking losses, prompted Riley to step down as coach of the Knicks. Instead of retiring, however, he took the reins down at South Beach, where he became the head coach and team president of the Miami Heat. However, like the Paul Brown example above, Riley crossed it over with CreateYourOwnVillain; the Knicks became the biggest reason as to why he couldn't win a championship in the late 90s, eliminating the Heat three straight years after making the Conference Finals against the Bulls. Unlike the Knicks, however, Riley stuck around, and although it took a while, he finally did achieve what he couldn't with New York - a championship to Miami.
* A very common way for new UsefulNotes/{{NCAA}} conferences to form, with several schools breaking away from one conference to start another. Both the Southeastern (1933) and Atlantic Coast (1953) conferences were created by large breakaways from the Southern Conference (and became [[MorePopularSpinoff More Popular Spinoffs]]). The modern Pac-12 started after several schools were kicked out of the old Pacific Coast Conference (but eventually most of the remaining PCC members joined the new conference). Then there's this RecursiveReality situation: In 1938 several schools left the Rocky Mountain Athletic Conference to start the Mountain States/Skyline Conference. In 1961, most of those schools joined with a few others to start the Western Athletic Conference. Then in 1999, eight WAC schools broke away to form the Mountain West Conference.

* ''LordOfTheDance'' was essentially Michael Flatley's "blackjack and hookers"-attempt after his contract re-negotiations with the ''Riverdance'' team broke down.

[[folder:Real Life]]
* Finland. The duchy of Finland had been a part of the Swedish kingdom until 1809, when Russia conquered and annexed her after a war. When TheRussianRevolution started and the Czar abdicated, a power vacuum was created in Finland. The bourgeoisie and the intelligentsiya wanted to stay with Russia; the nobility wanted to re-join Sweden. In the end, Finland eventually declared herself an independent state 6th December 1917.
* This is how Cambridge University was formed. A bunch of students were kicked out of Oxford, made their way across the country, and started their own university.
** This is also how University College London, the third university to be founded in England after Oxford and Cambridge, came into being. Unlike Oxford and Cambridge, it was entirely secular and allowed women in on an equal footing with men, inspired by the (then) radical philosophies of [[http://en.wikipedia.org/wiki/Jeremy_Bentham Jeremy Bentham]].
** The University of Bristol was genuinely founded by a man whose son failed to get into Oxford. The original 'college' is now the Physics Department.
* A couple of the early 20th-century industrialists started their own golf clubs, university endowments, etc., because they kept getting shunned by old money families.
** In the same way, New York City's grandest palazzo, the Metropolitan Club, was organized by J. P. Morgan in protest against not being admitted to some of the city's other exclusive private men's clubs. He showed ''them''.
* Quite a few Christian sects got started because of this trope:
** The Religious Society of Friends, better known as the Quakers, who formed their own sect of Christianity because its founder, George Fox, objected to the Anglicans' emphasis on ceremony.
** Martin Luther was excommunicated from the Roman Catholic Church. So he started his own church! With beer! And wives for the clergy!
** Henry VIII wanted to divorce his wife, Catherine of Aragon. When the Pope refused to annul Henry's current marriage, Henry formed his own church, the Church of England, installed himself as its head, and divorced her anyway.[[note]]Also, Catherine had been his brother's widow, meaning by the convention of the time his father had needed a special papal ruling to allow him to marry her at all, making his annulment request a bit hypocritical.[[/note]]
** The Baptist church in the United States in the 1800s favored abolition of slavery. The Southern Baptist church splits off in 1845 as an explicitly pro-slavery sect.
** The Free Methodist Church's name comes from their abolitionist roots. That, and their refusal to charge for seats.
** Christian humorist Adrian Plass, in one of his novels, mentions the concept of church groups splitting so often that some people are in danger of dissenting themselves right back to where they started...
** Mormon Fundamentalists are what happens when, deciding mainstream Mormons were wrong to abandon polygamy, hardcore religious nuts start their own. This came about, mind you, after Joseph Smith did the same thing to Christianity. (Although [[UsefulNotes/{{Mormonism}} Mormons]] would disagree with labeling their church as reformed.)
** The Episcopal Church in the US went through this following the election of a gay divorced man as bishop of New Hampshire. This caused many conservative Episcopal parishes to separate themselves into the Anglican Church in North America. For the time being the Episcopal Church retains membership in the international Anglican Communion (though relations are strained) and the ACNA has not been granted full communion.
** The ''[[https://en.wikipedia.org/wiki/Raskol Raskol]]'' was in protest of changes of the liturgy by the Patriarch Nikon.
** The [[https://en.wikipedia.org/wiki/Church_of_the_East Church of the East]] was created after the [[https://en.wikipedia.org/wiki/First_Council_of_Ephesus 431 Ephese Second Council]].
** And, of course, the OlderThanPrint TropeMaker of religious schisms, [[http://en.wikipedia.org/wiki/East%E2%80%93West_Schism the Great Schism]], whereupon the Roman Catholic and Eastern Orthodox Churches went their separate ways.
** Christianity ''itself'' is this trope embodied. It all started when the Rabbinic Judaism declared the Messianic sects as heretic in the synod of Yamnia 90 AD. The Messianic sects of Judaism then unified and became Christianity, which was organized under the successors of St. Peter as Catholic Church.
* This is notoriously commonplace with left-wing and socialist groups, who always seem to have trouble sticking together when disagreements arise. To wit: The Party for Socialism and Liberation, a major Marxist-Leninist organization in the United States, was split off from the Worker's World Party, and the Worker's World Party split off from the Socialist Workers Party, the Socialist Workers Party split off from the Communist Party USA, the Communist Party USA split off from the Socialist Party of America, and the Socialist Party of America split off from the Socialist Labor Party of America!
* In 1824, Andrew Jackson won the popular vote in the United States presidential election as one of four candidates running under the banner of the Democratic-Republican Party, but the Electoral College was split. The party elite in Congress ended up awarding the presidency to Jackson's rival, John Quincy Adams. In response, Jackson founded his own party, the modern Democratic party, and ran against Adams four years later, winning in a landslide.
*** And in response to ''that'', other elements of the disintegrating Democratic-Republican Party formed the Whig Party in 1833 to oppose Jackson. 15 years later, the Whigs were split over the issue of slavery which caused some of the anti-slavery Whigs to start their own Free Soil Party. Then in 1854, with both of those parties failing, former Free Soilers and northern Whigs got together to have another go at starting their own party: the modern Republican Party.
* This trope is credited as one of the reasons that Libertarianism (in the [[UsefulNotes/AmericanPoliticalSystem American sense]]) has so much trouble becoming a party with any real power. There are simply too many different groups that consider themselves Libertarian to ever organize.
* In the art world of the 1860s, the [[http://en.wikipedia.org/wiki/Salon_des_Refuses Salon des Refuses]] was started in Paris by a group of artists, now referred to as the Impressionists, who were infuriated at being constantly rejected by the official Salon de Paris.
** The Secession movement in Vienna, for much the same reasons.
* An early example in the technology world was a group of engineers known as the "Traitorous Eight" who worked under William Shockley, the inventor of the transistor. Irritated by Shockley's increasingly erratic behavior and iron-fistedness, the Traitorous Eight quit and formed Fairchild Semiconductor, which in turn spawned Intel.
** Software, too, especially [[http://www.gnu.org GNU]] and the [[http://www.fsf.org/ Free Software Foundation]]. Half of the software listed on [[http://sourceforge.net SourceForge]] would not exist without this trope, though it's usually spurred on by avoidance of restrictive licenses. Where religions have schisms, free/open-source software has "forks".
*** Granted, this trope is at the heart of FOSS software: according to their philosophy, anyone who thinks they ''can'' do better should be given the opportunity to prove it.
*** In the BSD world, [=OpenBSD=] and [=DragonFly=] BSD owe their existence to the fact that their founders had disagreements related to the development of [=NetBSD=] and [=FreeBSD=], respectively.
*** Allegedly, one of the main reasons ''Linux'' came about was because Linus Torvalds was becoming increasingly frustrated with several of the design decisions that went into the design of ''Minix'', a payware educational Unix distribution for personal computers, that he was forced to use at college.
*** Also, the main reason ALSA (Advanced Linux Sound Architecture) was created was because the OSS (Open Sound System) team had announced that they were going to split their driver packages into two- a free package for the most common consumer cards and a paid-for package for the higher end prosumer and professional sound cards. The Linux developers, whose motto was to have Linux running on ''everything'', were repulsed and thus started their own.
*** As a side note, a different issue with OSS' drivers, namely lack of security, was what gotten the [=OpenBSD=] developers to create their own OSS-like set of drivers.
*** When dying computing conglomerate and open-source champion Sun Microsystems got bought over by the database megacorp Oracle, Oracle proceeded to discontinue [=OpenSolaris=] several weeks later, barely hiding their greed and hinting that people who want to continue using Solaris will now be subjected to either a crippled free version called ''Solaris Express'', or have to pay up for a full version, where previously [=OpenSolaris=] was completely feature-compatible with the paid Solaris system save for the lack of tech support. Thing is, the license for [=OpenSolaris=] allowed the last version produced before Oracle shut the gates to the source code to remain free. The biggest contributors took the last version of the OS and forked, and ''illumos'' was born. [[note]]This is also a case of CreateYourOwnVillain, as the team originally had no plans to fork until Oracle decided to give them the finger.[[/note]]
*** At the same time as it screwed the [=OpenSolaris=] community, Oracle's behavior stifled the development of [=OpenOffice=]. Many of their developers were laid off or left on their own accord, they went on to form The Document Foundation and fork [=OpenOffice=] into [=LibreOffice=]. Oracle did eventually just give [=OpenOffice=] away to the Apache Foundation, but that only created a bitter FandomRivalry as a result.
*** And to show that things come in the power of three, Oracle buying up Sun also gave them control of the [=MySQL=] database engine, which they then proceed to cripple as to prevent the free option from competing fairly against their flagship product. Again, many devs left and forked the last Sun-produced version, this time into [=MariaDB=].
*** Another high-profile fork in the open-source community was the FFMPEG[=/LibAV=] schism in the software project that underlies nearly all video-related open source applications. Emerging from political turmoil within the FFMPEG project, the effects of the split the sent shockwaves through the broader open-source community, particularly Linux users, due to Ubuntu (one of the most popular distributions) initially siding with Libav. [[note]](see [[http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html here]] for further commentary, though it's a bit old).[[/note]] More than half a decade later, the two projects are still developed separately, with Libav pointedly ignoring FFMPEG's existence and FFMPEG continuing to expend effort to merge Libav's improvements back into itself in addition to doing its own development. The turmoil surrounding the issue has ceased, however, since most of the projects that initially sided with Libav have since gone back to FFMPEG.
* After Adidas was founded by Adolf "Adi" Dassler, he ran it with his brother for a while, until 1948, when a violent falling out between the two led Rudolf Dassler to move across the river and start his own sport shoe company, Puma. The city of Herzogenaurach is still fiercely split between the two brands to this day.
** The hatchet was supposedly buried with a ([[UsefulNotes/UnitedNations UN]]-sponsored) soccer match, but Adidas and Puma remain independent concerns.
** The Dassler issue wasn't even a "Start My Own" issue but rather a clean-cut split. The original company was "Gebrüder Dassler OHG", read "Dassler Brothers partnership". Puma isn't an offshot of Adidas, both Adidas and Puma are split successors of the original Dassler firm. It's just the original factory that Adidas retained. And don't get me started with the [[TechnicianVersusPerformer original shoemakers going for Adi and the original business going for Rudi]], let alone [[EpilepticTrees the brothers trying to denounce each other as Nazis to the American after the war etc.]], it got very nasty.
* Ferrari is involved in ''three'' examples:
** First, inter-company politics in the early sixties led a group of engineers to jump ship and form their own company, ATS. Unfortunately, their first effort came across as lackluster and they folded after a couple of years. However, they were revived in TheNewTens.
** In the mid-sixties, Ferruccio Lamborghini, president of what was then primarily a tractor manufacturer, came to Enzo Ferrari to complain that his recently purchased Ferrari had a faulty clutch. He also explained that he had tried the clutch from one of his own tractors in the car and it worked fine. A fierce argument followed, and Lamborghini looked through his car some more and decided that his company already had the ability to make most of the necessary components for a luxury automobile. The rivalry continues to this day.
** In 1963 Ferrari was desperate to secure funding, and the company entered serious talks with Ford about purchasing the company. When Enzo Ferrari learned that the Americans wouldn't allow him to keep control of the racing team, he broke off the negotiations. Ford (and Henry Ford Jr. in particular) was so incensed that they designed the [=GT40=] specifically to challenge Ferrari's record in the 24 Hours of Le Mans. The [=GT40=] went on to win Le Mans four times in a row.
* Garry Kasparov split from FIDE, the World Chess Federation, to form the PCA (Professional Chess Association) in 1993.
* Sean Combs was fired from Uptown Records during the early 90's. Afterward he formed his own label, Bad Boy Records. The latter is more or less still thriving while Uptown folded.
* Dave Thomas (the restaurateur, not the actor) made a name for himself as assistant to Colonel Harland Sanders. Had he stayed in line, Thomas would probably end up inheriting the reins of KFC, but due to personal disagreements with the good Colonel, Thomas struck out on his own and founded his own restaurant chain, which he named after his daughter Wendy.
* UsefulNotes/TheodoreRoosevelt disliked UsefulNotes/WilliamHowardTaft and the growing conservatism of the formerly moderate Republican party (and felt personally betrayed by his former protege Taft's role in that rightward shift), so after a failed attempt to unseat Taft as the Republican nominee (few states held primaries in that era, so party bosses had almost complete control over the nominating process and they were firmly in Taft's corner) he started his own progressive liberal party in 1912, known informally as the Bull Moose Party. As with all United States third parties, it failed and instead split the vote so the [[UsefulNotes/WoodrowWilson Democrat]] won.
** That was Roosevelt's intention. He hated Taft's policies and would have rather seen a Democrat win than Taft get re-elected. [[HangingSeparately So he created the new party to sabotage Taft]]. And in the process he left Taft with the ignominy of being the only incumbent US president to finish ''third place'' in his reelection bid.
** Despite the failure of the Bull Moose movement, most of its adherents threw in their lot with the Democrats after Franklin Roosevelt - 5th cousin of Theodore - announced the New Deal policy platform in the 1930s.
* When Brazilian movie magazine SET was sold to a different publisher, one of the editors went to start its own publication, ''Preview''. Both have a FandomRivalry now (it helps that said editor's boss at SET eventually returned to the magazine...).
* The 13 British colonies in North America had a bit of a problem with the mother country's bad habit of forcing legislation (and taxation) on them without their permission (since it would be too much of a hassle to ship American politicians across the Atlantic to Parliament), so they decided to start their ''own'' independent government, with an eye towards fixing all the grievances they had with Britain. Britain of course took exception to that, the Americans took exception to their exception, the Americans won, and history was made.
** And of course the UsefulNotes/AmericanCivilWar was a failed attempt by the rebellious southern states to form a new country due fears that the country would restrict or ban Slavery (and a bunch of other, minor political and social tensions as well). The same conflict led to the creation of the state of West Virginia, when it turned out that those Virginians living in the Appalachians wanted nothing to do with the whole 'slavery' or 'secession' stuff and decided to secede from Virginia and rejoin the glorious 'murrikan motherland.
* Boyd Coddington's hot rod shop, Hot Rods by Boyd, faced bankruptcy in 1998. So, president Chip Foose left to form his own company, Foose Design. The two companies endured a fierce rivalry right up until Boyd Coddington's death ten years later.
* Creator/CarpeFulgur, the company responsible for the localization of ''VideoGame/RecettearAnItemShopsTale'', was founded by two guys trying to get into the localization business only to be constantly turned down due to lack of experience. So they decided to create their own company to earn that experience.
* The United Services Automobile Association started as an insurance co-op formed by a group of American Army officers who couldn't get car insurance. Over the decades it has gradually expanded to become a rather successful financial institution offering insurance, banking, and various other services to American military personnel and their families.
* When Creator/{{The WB}} and Creator/{{UPN}} decided to merge and become Creator/{{The CW}}, the new network did not include any of the UPN affiliates owned by Fox (including many of the big-market stations). In response, Fox created a new network for these stations, Creator/MyNetworkTV.
* Creator/{{Disney}} as it exists today came about from Creator/WaltDisney losing his contract with Creator/{{Universal}} in 1928. The studio later founded its own distribution company Buena Vista in 1953 after disagreements with its previous distributor [=RKO=] Radio Pictures.
** [[Creator/HarmanAndIsing Hugh Harman and Rudolf Ising]] were two Disney animators who stayed with Universal after Walt Disney left in 1928, and they in turn left Universal in 1929 to form their own studio. In 1933 they teamed up with producer Leon Schlesinger, who got them a contract with Creator/WarnerBros to distribute their new ''WesternAnimation/LooneyTunes'' series. Then in 1934 they left that studio and went to work for Creator/{{MGM}}.
** Creator/UbIwerks left Disney in 1930 to create a new studio with Disney's former distributor Pat Powers. Although he pioneered many new animation techniques in his shorts, Iwerks' studio was never profitable and he was dropped by Powers in 1936. After his studio went bankrupt a year later Iwerks retired from animation altogether, opting instead to rejoin Disney in 1940 as the head of their newly-formed research and special effects department.
** Creator/ArtBabbitt left Disney as a result of him leading the 1941 studio animator's strike (and after a lawsuit he filed against them in 1947) and created [[Creator/ColumbiaCartoons UPA]] in 1948, which pioneered the LimitedAnimation technique that was prevalent during UsefulNotes/TheDarkAgeOfAnimation. After decades of bad blood he buried the hatchet with Disney shortly before his death in 1992, and was named a Disney Legend in 2007.
** Creator/DonBluth was a Disney animator who was unhappy with the mediocre animated films that the studio was churning out after the death of Walt Disney. He and twelve other animators left Disney in 1979 to form their own animation studio, with the intention of replacing Disney or at the very least providing Disney with some genuine competition to force them to make better movies. The studio ended up succeeding on both fronts: it replaced Disney as the premier American animation studio in the 1980s ''and'' it forced Disney to step up their game... [[GoneHorriblyRight but as consequence]] Disney regained its powerhouse status in the 1990s and Bluth couldn't keep up, leading to the closure of his original studio and then later his second studio.
** After being fired from Disney in 1983 by then-studio head Ron Miller, [[Creator/PixarRegulars John Lasseter]] was tapped by Ed Catmull and Creator/SteveJobs to create CGI advertisements for their new line of computers. Lasseter's ad department turned into a short film department after buyers became interested in seeing how extensively the software could be used, and these shorts caught the attention of Jeffrey Katzenberg (who had replaced Miller as Disney's studio head in the mid-1980s). He signed the studio (renamed Creator/{{Pixar}}) to create a series of computer animated films in the early 1990s, and the rest is history.
** Creator/RichardRich left Disney to form Rich Animation Studios in 1985 after disagreements with Disney Animation head Peter Schneider over the direction of [[Disney/TheGreatMouseDetective his next film]]. Unlike Don Bluth his studio is still around today, but it was never anywhere near as successful as Bluth's was.
** Jeffrey Katzenberg left Disney in 1994 after arguments with then-CEO Michael Eisner, and went on to co-found [[Creator/DreamWorks DreamWorks SKG]] with Creator/StevenSpielberg and David Geffen. The best-known, most successful part of the company turned out to be Katzenberg's Creator/{{DreamWorks Animation}}. Spielberg's live-action portion, [=DreamWorks=] Studios, had some success in the late 1990s/early 2000s but is much less active today.
* After getting fired from Gamespot for undisclosed reasons (though the most popular is for giving a mediocre review to ''VideoGame/KaneAndLynch: Dead Men'' while the game was advertised on the site), Jeff Gerstmann went off to start the gaming news site GiantBomb alongside other former Gamespot journalists.
* [[Series/MisterRogersNeighborhood Mister Rogers]] saw the violence in children's cartoon and television, so created the Neighborhood instead.
* [[http://www.reactos.org The ReactOS project]], an open-source Windows clone, began as a reaction to some of the more questionable business practices of Microsoft. [[MeaningfulName It's also how it got its name.]]
* Even Al Qaeda [[http://bigstory.ap.org/article/ap-exclusive-rise-al-qaida-saharan-terrorist is not immune to this]], with [[http://www.huffingtonpost.com/2013/05/28/moktar-belmoktar-terroris_n_3349176.html Moktar Belmoktar]], a former disgruntled employee starting his own terrorist group after Al Qaeda wrote him a scathing letter accusing him of, among other things, failing to carry out a single operation, not filling out expense reports, not attending meetings [[ArsonMurderAndJaywalking and not answering his phone when they called]].
* Creator/OrionPictures was created by former Creator/UnitedArtists executives who were fed up with its then-owner Transamerica's influence on the company.
* Literature/FactionParadox started out as characters in the Franchise/DoctorWhoExpandedUniverse, specifically the Literature/EighthDoctorAdventures. When someone else was allowed to write a novel that not only changed the Faction's whole character but also derailed his plans for portraying the Time War they were involved in, their creator decided to spin the Faction off into their own series with its own, separate mythos.
* [[UsefulNotes/EsperantoTheUniversalLanguage Esperanto]], along with any other constructed language.
** Ido, its most popular offshoot.
* Mary Seacole, a Jamaican nurse in the Crimean War, was rejected by Florence Nightingale for being black, so she started her own hospital on the front line the British Hotel. She was ten times more involved than Florence and went to the front line herself. She died penniless, but she has been remembered by history, no matter if no one really remembers who she was outside of certain circles.
* A (possibly apocryphal) story has it that the founder of Netflix did so after his outrage over a $40 Blockbuster late fee inspired him to start his own video rental service. [[Series/HouseOfCards With blackjack!]] [[Series/OrangeIsTheNewBlack And hookers!]]
* Netflix's popularity has encouraged major studios like Disney and Warner Bros to start their own streaming services rather than license their content to Netflix or other services like Hulu or Amazon Prime.
* Political parties, especially those positioned far from the center, ussualy start out this way with some radical from a more "grounded" party feels their party sold out and brakes of. For example, every left wing organization or party in Sweden, be they democratic socialists, syndicalist or outright Stalinist descends from the left-to-center-left Social Democratic party in one way or the other.
** Similarly, high profile members of far-right parties in the UK have a habit of suddenly deciding that the party is too moderate for their tastes and splitting off to form parties more in keeping with their personal ideals. Prominent examples include former British National Party members Paul Golding and Jayda Fransen, who split away to form Britain First, and would-be UKIP leader Annie-Marie Waters, who suffered a surprise defeat in the 2017 UKIP leadership election, and subsequently stormed out of the party and formed For Britain.
* In the Philippines, the Liberal Party got its start in the 1940s as a splinter-off faction of the Nacionalista Party (virtually the only party in power at the time, as the country/semi-US-colony was essentially a one-party state). Disgruntled party members, chief among them Manuel Roxas (who would go on to be President in 1946), left and started their own party to challenge the Nacionalistas at the polls. Not that it really mattered party-wise, because the two parties differed very little in ideological leaning, and party-switching or "turncoatism" was rifeóa reality that still holds today under an ostensibly multiparty government. The Liberals in fact were the originators of the "start-your-own-party" trend regardless of ideology or beliefs.
* This was essentially what lead to the creation of the [[http://en.wikipedia.org/wiki/Dassault_Rafale Dassault Rafale]] - France was originally collaborating with the UK, Germany, Italy and Spain on the [[RealLife/CoolPlane Eurofighter project]], but they wanted to make a carrier-capable version; when it became clear that none of the other countries wanted to bother with one, France withdrew to pursue their own project. Similar to many other examples of this trope, the Rafale actually entered service before the Eurofighter.
* Seymour Cray was a star employee of Control Data Corporation during the mainframe computer era - until management turned down his proposal for a next-generation super-computer. Cray quit and formed his namesake super-computer company, which Control Data - at the time one of '[[https://en.wikipedia.org/wiki/BUNCH IBM and the Seven Dwarfs]]' - never fully recovered from.
* In the mid-70s, Creator/GeorgeLucas wanted to do a feature-film version of ''ComicStrip/FlashGordon'', so he set out to acquire its rights. But when he was outbid by Dino [=DeLaurentiis=], [[Franchise/StarWars he decided to create his own space opera]].
** This is a double example. After deciding to create his own movie, Lucas had a ''very'' grand image for the special effects (poor effects being one of the things keeping sci-fi mostly confined to B-movies). When he couldn't find anyone who made the grade, he got together some college buddies and revolutionized special effects with his own company. They're still around today- you probably know them as ''Creator/IndustrialLightAndMagic''.
* The [[WebGames browser game]] ''VideoGame/PoliticsAndWar'' was inspired by the creator playing ''VideoGame/CyberNations''. The games have similar concept and execution, but ''Politics And War'' is much more in-depth with deeper mechanics and gameplay, and, in recent years, a much more active userbase. On most online forums, ''Politics And War'' is considered the superior game.
** ''VideoGame/CyberNations'' did something similar earlier on to ''VideoGame/NationStates''. While ''Nation States'' is more of a day-to-day executive decision making game with more{{Roleplay}} elements, ''Cyber Nations'' is inspired by it, but lets you micromanage more aspects of your nation, such as going to war, trading, etc. The games are different enough that comparing them is like comparing Apples to Oranges
* This is effectively the story behind the Franchise/MarvelCinematicUniverse: after dealing with flops made by other studios with their characters and only getting a small percentage of the profits the ones that were hits made, Marvel decided to make ''Film/IronMan'' on their own, and the rest is history. Possibly a subversion since Marvel was later bought by Disney (see above for the numerous studios founded by ex-Disney employees), but Disney has let the MCU function fairly independently.
* After Steve Jobs was KickedUpstairs at Apple due to his stubborn personality rendering him unable to get along with anyone else in the company, he decided to quit and form a new computer company, called [=NeXT=]. [=NeXT=] was basically made up of every stereotype about Apple turned UpToEleven. Its products generated a lot of buzz for their ease-of-use, technical sophistication, and striking aesthetic designs, but they were also [[CrackIsCheaper ludicrously expensive]] and [[NoBackwardsCompatibilityInTheFuture not compatible with any existing products]] [[note]]Bill Gates famously quipped "[=NeXT=] has an interesting feature called incompatibility"[[/note]]. This came at a time when the industry was rapidly embracing the standards set by the UsefulNotes/IBMPersonalComputer, which also had the effect of driving costs down, leading to poor sales of NeXT's computers. Ironically, Apple ended up bringing Jobs back on board when they acquired [=NeXT=] in order to use its software as the basis of a next-gen operating system for the Mac, after having bungled all attempts at developing one internally. Though his initial job title after the acquisition was an "advisor," Jobs quickly rose to position of CEO, which he held until just before his death in 2011.
* This happens a lot in martial arts, especially after a particular organisation's founder has died. Often, a successor is chosen and many of their other protégés may disagree with this. There can often be other reasons as well, such as differences in what way the martial art chooses to (or not to) evolve or even [[MoneyDearBoy what membership dues are required]].
* The ice cream chain [=KaleidoScoops=] was started in 1999 by a bunch of Baskin-Robbins owners who had their franchises terminated due to underperformance.
* Creator/MasiOka decided he wanted to break into the game industry, since he enjoyed playing games and wanted to make some, but the studios he approached with his ideas turned him down. So, he asked a bunch of college kids about to graduate if they wanted to come work for him,[[note]]One imagines their response was somewhere along the lines of, [[SarcasmMode "Is the sky blue?"]][[/note]] and that's how Creator/MobiusDigital got started.
* When the [[CultClassic cult]] online game ''VideoGame/CityOfHeroes'' was shut down [[ScrewedByTheNetwork for some reason]] and NC Soft seemed unwilling to sell it, fans immediately considered developing a replacement, which became ''VideoGame/CityOfTitans''. Less than three months later, even before the original game's shutdown had been completed, founding member Golden Girl started ''another'' project, ''Heroes and Villains'', over CreativeDifferences. ''City of Titans'' will be a [[SpiritualSuccessor Spiritual Sequel]] (as in, revamping the game mechanics to some extent), while ''Heroes and Villains'' is apparently supposed to be ''City of Heroes'' with the SerialNumbersFiledOff.
* The Metropolitan Opera Company was founded by a group of businessmen who were annoyed by being unable to obtain box seats at the Academy of Music.
* Creator/KunihikoIkuhara directed the second to fourth season of the 90s version of ''Manga/SailorMoon''. But when Creator/ToeiAnimation didn't give him enough creative control for ''[=SuperS=]'' he [[Anime/RevolutionaryGirlUtena decided to create his own shoujo series]].
* When the Sony forums were hacked in 2011, the fanbases for their two biggest game show properties (''Series/WheelOfFortune'' and ''Series/{{Jeopardy}}'') migrated to fan forums and have been there ever since.
* After Jean Chalopin left Creator/DicEntertainment, he went on to found his own company, C&D[[note]]Standing for Créativité et Devéloppement", just as "D.i.C" had (originally) stood for "Diffusion, information, et Communication".[[/note]], which had produced its shows in a similar style.
* The hotel chain America's Best Value Inn was started in 1999, and most of its first properties at the time were recently rebranded from other chains (predominantly Best Western and unbranded properties). The same is true of rival Magnuson Hotels.
* In 1981, directer Larry Cohen was removed from the director's chair of a remake of ''[[Literature/MikeHammer I, the Jury]]'', just before filming began.[[note]]Though he still got screenplay credit[[/note]]. Since he already had shooting space reserved, he decided to use it to shoot his own movie. That movie turned out to be ''Film/QTheWingedSerpent.''
* Adam Pacitti, Adam Blampied, Jack King, Ross Tweddell, and Sam Driver resigned from [=WhatCulture=] in fall 2017. By November, four of them [[note]]Blampied's contract was terminated after he confessed to soliciting female fans online[[/note]]had formed a new wrestling-themed Website/YouTube channel, WebOriginal/{{Cultaholic}}.
* Quite a few Japanese animation studios were founded by well-respected producers, animators and directors:
** Yutaka Fujioka formed Creator/TMSEntertainment after his previous company Tokyo Ningyo Cinema failed.
** Ex-TMS animator Creator/HayaoMiyazaki and ex-Toei animator Creator/IsaoTakahata teamed up to co-found Creator/StudioGhibli
** Kenji Horikawa left Creator/ProductionIG in 2000 for his native Toyama to follow a promise he made to his family. He would later go on to form his own animation studio, Creator/PAWorks, as there were no animation studios nearby at the time.
** Creator/{{GONZO}} was formed by Showji Murahama, Hiroshi Yamaguchi, Shinji Higuchi and Mahiro Maeda after they left Creator/StudioGainax in 1992. When GONZO went bankrupt in the early 2010s, most of their staff would later go on to work at Creator/StudioGokumi.
** After Masahiko Minami left Creator/{{Sunrise}} as an animation producer, he would later go on to form Creator/StudioBones.
** Mikihiro Iwata, also a producer for Sunrise, would later go on to found Creator/A1Pictures in 2005.
** Former Creator/MushiProductions animators Masao Maruyama, Osamu Dezaki, Rintaro and Yoshiaki Kawajiri formed Creator/{{Madhouse}} in October 1972. When Maruyama retired from Madhouse in 2011 at the age of 70, he went on to found Creator/{{MAPPA}}.
** After Jiyū Ōgi left Creator/{{AIC}}, he would later go on to found Creator/ProductionIMS in 2013.
** Ex-Tatsunoko Production and Kitty Film producer Tomoyuki Miyata founded Creator/JCStaff in 1986 after serving in Kitty Film's Mitaka Studio.
** Anime producer Nagateru Kato left Tatsunoko Pro to serve as a producer for MOVIC before going on to form Creator/{{TNK}}.
** Hayato Kaneko served as an animation producer for the animation studio Frontline. He would later go on to found his own company, Creator/SilverLink, in 2007 after leaving Frontline.
** Studio Chizu was established by producer Yūichirō Saitō and director Creator/MamoruHosoda after leaving Madhouse in 2011.
** When Studio Ghibli temporarily halted production of their works following Creator/HayaoMiyazaki's temporary retirement, producer Yoshiaki Nishimura left the studio and formed Creator/StudioPonoc to produce ''Anime/MaryAndTheWitchsFlower''.
