History Main / ContinuityNod

* An [[ThisDomainIsIrrelevant untitled]] webcomic frequently makes use this, frequently brining up often inconsequential side points from older comics and twisting their meaning and often connecting them to all kinds of other events. Recently it has been [[http://thisdomainisirrelevant.net/592 revealed]] that this is all the machination of the {{Illuminati}} of which Steve Jobs is a member.

* The BigFinish ''Series/DoctorWho'' audio drama "The Kingmaker" features a scene in which a stranded Doctor leaves a note for his future self to find. It is [[MeanwhileInTheFuture "later"]] mentioned to have been delivered by "some bloke with big ears and a [[BritishAccents Northern accent]]", an apparent nod to Christopher Eccleston. In that same story, Tom Baker provides a cameo in the form of a clip from a history documentary, presented as the Doctor's taped notes (not actually Tom Baker, but a very convincing impression by Jon Culshaw).
** Another character with an accent similar to Eccleston's also gets in a "Fantastic". Big Finish: tweaking the limits of BBC licensing restrictions for over 10 years.
** And the fifth Doctor audio "The Whispering Forest" features the Green Crescent medical symbol from "New Earth". At the end, [[spoiler: the Mara]] sarcastically asks if the Doctor is leaving Purity because it's "too green for you", referencing the final line of "Kinda".

* During the line to get in ''The Simpsons Ride at UniversalStudios, various clips from ''WesternAnimation/TheSimpsons'' are shown on [=TV=]s. One of them is a clip of Doc Brown from ''Film/BackToTheFuture'' selling the rights to [[Ride/BackToTheFutureTheRide the time travel compound]] to Professor Frink.

* GilbertAndSullivan indulged in this on a few occasions. In their seldom-performed penultimate collaboration, ''Utopia Limited'', a nod is made to ''HMS Pinafore'' as one of the British Flowers of Progress is a naval officer named Captain Corcoran - which is also the name of the captain of the Pinafore ([[ItMakesSenseInContext for most of the operetta, at least]]). In his introductory song in the Act I finale of ''Utopia Limited'', there is even a direct musical quote from the similarly named character's introductory song in ''HMS Pinafore'', "I am the captain of the Pinafore". It is somewhat uncertain whether they are intended to be the same character.
** ''Utopia Limited'' also has a nod to ''The Mikado'', specifically the title character's song about his {{Cool And Unusual Punishment}}s:

** This occasionally gets to ridiculous extremes, like Turkish President Abdullah Gul's reference to "400 years of peace" between Turkey and Russia. Never mind that for the last 400 years, relations between Turkey and Russia are better described by...what's the word...oh, yes, ''war''.

* During the line to get in ''The Simpsons Ride at UniversalStudios, various clips from ''WesternAnimation/TheSimpsons'' are shown on [=TV=]s. One of them is a clip of Doc Brown from ''Film/BackToTheFuture'' selling the rights to [[Ride/BackToTheFuture the time travel compound]] to Professor Frink.

'''Remember, it's only a continuity nod ''if the events happen in the same continuity''. Otherwise it's a MythologyGag.'''

** Outside of the above album, the Forever character from Into the Electric Castle is revisted in a single song in Universal Migrator and is revealed at the end of The Human Equation.

* Chapter 71 of ''FanFic/TheGamesOfTheGods'' explains why Dior, Steward of Gondor, never married. This is a nod to ''Literature/ThePeoplesOfMiddleEarth'', which established that Dior had no son.

* ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' has several to both the ''Franchise/SonicTheHedgehog'' and '']]VideoGame/MegaManClassic Mega Man]]'' video games and comics.

** The armor the kids get at the end looks very similar to the Marine BDU from Combat Evolved.

** "Savoy Truffle" contains the line, "We all know 'Ob-la-di-bla-da', but can you tell me where you are", referencing "Ob-La-Di, Ob-La-Da" from [[TheWhiteAlbum the same album]].

** "Wanted Dead Or Alive" from ''Slippery'' mentions "I'm a cowboy, on a steel horse I ride". "Ride Cowboy Ride" and "Stick To Your Guns" from ''New Jersey'' also mention cowboys, as (obviously) does Jon Bon Jovi's solo hit, "Blaze Of Glory" (from the ''[[YoungGuns Young Guns II]]'' soundtrack.

* Occurs regularly in ''AstroCity'', as befitting a series with a single writer. Most Continuity Nods appear as sidelong references to other characters and events in the chronological past/present, even if the subject hasn't had a published appearance yet.

* The ''FanFic/FacingTheFutureSeries'' does this as much as [[DannyPhantom the series it's based on]].
