History Main / SharedUniverse

* The Midnight Rose collective, a group of British SF writers, published several shared-universe anthologies in the early 1990s, with settings including ''Literature/{{Temps}}'' (tongue-in-cheek superhero stories) and ''The Weerde'' (shape-shifting aliens are the source of all the world's myths and conspiracies). Contributors included StephenBaxter, Creator/NeilGaiman, MaryGentle, Creator/DavidLangford, Creator/KimNewman, and Creator/CharlesStross.

* [[http://youtu.be/bKw-NfxseUY This easter egg]] from VideoGame/AssassinsCreedIV heavily suggests that Franchise/AssassinsCreed and VideoGame/WatchDogs share a universe.

* ''Film/PulpFiction'' and ''Film/ReservoirDogs'', both [[QuentinTarantino Tarantino]] films, share a link in that Vincent and Mr. Blonde are [[spoiler:apparently brothers]].

** Currently, ''ComicBook/{{Invincible}}'' shoulders a lot of weight when it comes to establishing a larger Image universe. Characters from Kirkman's other books popping up frequently, and big events (like the funeral of the Guardians of the Globe or the Invincible War) feature just about anyone who's anyone in the company at the time. At one point Mark was even a member of the Pact, a team consisting of him, [[NobleCauses Zephyr Noble]], {{Firebreather}}, and Shadowhawk.

* The ''KamenRider'' series, specifically the Showa Era all exists in the same universe as evidenced by the presence of this common enemy called "[[BigBad The Great Leader]]". Later on in the old Heisei era, KamenRiderKuuga and KamenRiderAgito shared the same universe. And then in the new Heisei Era, KamenRiderDouble, KamenRiderOOO, and Series/KamenRiderFourze exists in their own SharedUniverse for their [[BigBad Big Bads]] are all linked by the NebulousEvilOrganization "Foundation X" (the new generation's equivalent of Shocker, it would seem).

* ''{{Rugrats}}'', ''TheWildThornberries'', and ''RocketPower''.

* After a great many hints in the various DanSchneider shows, ''Series/ICarly'' canonized that it exists in the same universe as ''DrakeAndJosh'', ''{{Zoey 101}}'' and ''{{Victorious}}''.

** Also frequent crossovers with TheBeverlyHillbillies.

* ''Series/DiffrentStrokes'', ''Series/TheFactsOfLife'' and ''HelloLarry''.

* ''WesternAnimation/FairlyOddParents'' seems to share a reality with DannyPhantom because in a first season episode of DannyPhantom, Tucker and Danny are standing in front of a Crash Nebula video game. Crash Nebula is an in universe comic book character that originated in ''WesternAnimation/FairlyOddParents''.

* Lunaverse alum GrassAndClouds2 is now running a SharedUniverse of his own, Fanfic/TheCadanceverse. It is music themed, and features Cadance as the princess (after both Celestia and Luna were corrupted), Octavia as her student, and Vinyl, Fluttershy, Lyra, and two background ponies as the other Element Bearers.

* ''PulpFiction'' and ''ReservoirDogs'', both [[QuentinTarantino Tarantino]] films, share a link in that Vincent and Mr. Blonde are [[spoiler:apparently brothers]].
** Originally the connection was intended to be much stronger. In early drafts of the script, the briefcase Vincent and Jules retrieve contain the diamonds stolen in ''ReservoirDogs''
** Additionally, Lee Donowitz from ''TrueRomance'' is the son of Sgt. Donny Donowitz from ''IngloriousBasterds''. Furthermore, Alabama from ''True Romance'' is the same Alabama that Mr. White mentions in ''Reservoir Dogs''. Meaning all four movies are in the same universe.
* ''Machete'' and ''SpyKids'' share the same universe as confirmed by WordOfGod, one must wonder which came first in terms of timeline, the misadventures of Uncle Machete or the Spy Kids?

** Also, when you add up the loads of crossovers, you get these series in the same universe: ''KamenRider'', ''SuperSentai'', ''MetalHeroes'', ''Kikaider'', ''Inazuman'', ''Series/KaiketsuZubat''.

* Most of the series produced by Jack Webb take place in the same universe, including ''Franchise/{{Dragnet}}'', ''Series/AdamTwelve'', ''{{Emergency}}'' and the short-lived Robert Conrad vehicle, ''The D.A.''

* Many of the animated works of Creator/{{Pixar}} seem to fall into this category, mainly because of the countless references in their films and shorts that overlap with each other. The Pizza Planet Truck from WesternAnimation/ToyStory is the best example of this, which has showed up in nearly every feature film of theirs.

* Videogame/GrandTheftAuto and Videogame/{{Manhunt}} (both developed by Rockstar Games) take place within the same universe, as confirmed by overlapping references like placenames, vehicles and fictional brands. Rockstar's Videogame/{{Bully}} is also a possibility though there are not enough references that verify this.

* Some Rockstar franchises like Videogame/GrandTheftAuto and Videogame/{{Manhunt}} take place within the same universe.

* Most of the series produced by Jack Webb take place in the same universe, including ''Radio/{{Dragnet}}'', ''Series/AdamTwelve'', ''{{Emergency}}'' and the short-lived Robert Conrad vehicle, ''The D.A.''

* ''VideoGame/{{Marathon}}'' takes place in the same universe as ''PathwaysIntoDarkness''. There is even a terminal in the first ''Marathon'' game (which is a historical record) that talks about the events of ''Pathways''.

* The Filmways-produced ''Series/PetticoatJunction'' and ''Series/GreenAcres'' were both set in the town of Hooterville, and characters from each gravitated to the other fairly regularly.

* Because Marvel Films holds the rights to all MarvelComics characters not given to other studios (Film/SpiderMan, Film/{{X-Men}}, Film/FantasticFour and Film/GhostRider), they have managed to bridge together a single continuity family with links between the characters' stories. Nick Fury makes a cameo in ''Film/IronMan'' referring Tony Stark to the "Avenger Initiative," Tony appears in the film of ''Film/TheIncredibleHulk'' talking to General Ross about putting a team together (also having a nod to ''CaptainAmericaTheFirstAvenger''), ''IronMan II'' gave many hints to ''Film/{{Thor}}'', and the whole thing came together in ''Film/TheAvengers'' as a CrisisCrossover. This cycle is planned to be repeated, starting with ''Film/IronMan3'' in 2013 and building up to to an ''Avengers'' sequel in 2015.

** Also, when you add up the loads of crossovers, you get these series in the same universe: ''KamenRider'', ''SuperSentai'', ''MetalHeroes'', ''Kikaider'', ''Inazuman'', ''KaiketsuZubat''.

* The Russian ''DeathZone'' series is worked on by several known Russian sci-fi authors and is loosely based on the ''{{STALKER}}'' games. Unfortunately, this tends to create certain [[CanonDisContinuity lapses in continuity]]. For example, in AndreiLivadny's novels, the Order is portrayed as a rational group that believes in the existence of an otherdimentional point known as the Node based purely on empirical evidence. In RomanGlushkov's books, they are fanatics spouting religious nonsense about the Holy Node before sacrificing themselves for the cause. It could be explained that these are different members of the Order interpreting their teachings, if they were not using the same characters.
