* ''Webcomic/TheNoob'':
** When ''The Noob'' parodied the "Time Warp" song from the famous stage play and 1975 comedy movie ''Film/TheRockyHorrorPictureShow'' in its episode #299 [[http://www.thenoobcomic.com/index.php?pos=299 "The Dungeon Lifecycle"]], a fan on the comments board claimed that the webcomic was ripping off the {{MMORPG}} ''VideoGame/CityOfHeroes'', because they had used the "jump to the left" joke first; naturally, this came from a ''[=CoH=]'' mission packed with ''RHPS'' references.
** Similarly, a fan asked on the comments box whether the "Eldritch Blob" monster was a reference to "Eldritch Deathlord" from ''VideoGame/WarcraftIIIReignOfChaos'', not knowing that the term ''eldritch'' is dated by Merriam-Webster online to the year 1508. Horror writers like Creator/EdgarAllanPoe, Creator/ClarkAshtonSmith and Creator/HPLovecraft were very fond of the word, and it is from these that its modern use in fantasy comes.
* Many people will tell you that ''[[Webcomic/TheOrderOfTheStick Order of the Stick]]'' invented the RPGMechanicsVerse trope, but as that page shows, at least two {{anime}} examples, ''Beet the Vandel Buster'' and ''Manga/MagicalCircleGuruGuru'', beat ''[=OotS=]'' by about one and nine years, respectively. ''Order of the Stick'' is also frequently accused of stealing material from Skyrim, even though the creator has declared he has never played the game.
* Believe it or not, there are some people who credit ''Webcomic/{{Homestuck}}'' for coining the phrase "grimdark". It is a meme from ''TabletopGame/{{Warhammer 40000}}''.
** The same applies with "fuckass", from ''Film/DonnieDarko''.
** The concept of romance applying to four separate types of relationships, only one of which being romance as we typically think of it, [[TheFourLoves was first proposed by C.S. Lewis,]] who based his ideas on ancient Greek philosophy.
*** In general, troll culture is commonly thought to be an entirely original invention. While it can't be said for sure if any of it was intentional, many aspects of troll culture are very reminiscent of Creator/SMStirling's ''Literature/TheDraka'', the Dremora civilisation from ''Franchise/TheElderScrolls'' (who even use the same alphabet and look very similar to trolls in physical appearance), and real-world Sparta.
** The theme song of the Midnight Crew, "I'm a Member of the Midnight Crew", is commonly believed to have been written for the comic. It was actually written by vaudeville singer [[http://en.wikipedia.org/wiki/Eddie_Morton Eddie Morton]] in 1909, and the Midnight Crew are named after ''it''.
*** Speaking of the Midnight Crew, they're thought to be dark parodies of the ''Webcomic/ProblemSleuth'' crew made specifically for ''Homestuck'', in keeping with Hussie's trend of taking from previous ''Webcomic/MSPaintAdventures'' comics and referencing them in later ones. While the parody part of that statement is true, the characters were initially ''from'' ''Problem Sleuth'' -- they were a rival gang Team Sleuth encountered in non-canon bonus comics, and [[EarlyInstallmentWeirdness just as silly]], to boot.
** Some readers, especially of the younger type, are unaware that the trolls' symbols are alchemical symbols associated with [[WesternZodiac signs of the Zodiac]] and not an original creation.
** Say "Put the bunny back in the box" to someone and they'll probably think you're referencing ''Webcomic/{{Homestuck}}''. In fact, ''Webcomic/{{Homestuck}}'' got it from ''Film/ConAir'' (and the line is even triggered by examining a ''Film/ConAir'' poster).
* In one strip of ''Webcomic/{{XKCD}}'', Randall Munroe points out how people have complained about [[http://xkcd.com/1227/ The Pace of Modern Life]] since the dawn of the ''20th'' century.
* Many people think that ''8-Bit Theater'' started the sprite comic genre, but that honor goes to Webcomic/NeglectedMarioCharacters.
