History AnachronismStew / WesternAnimation

** And then there's ''WesternAnimation/ArthurAndTheSquareKnightsOfTheRoundTable'', an Australian animated series that takes this trope and wrings it dry. Seriously, Merlin invented the movie camera and film projector?

*** And [[CreditsGag the credits]] mention Robot Zorro, among other strange characters. With Creator/JamesEarlJones as the voice of the Magic Taco.
*** The ending ''rap'' playing over the movie credits also suggests that Zorro will "cut your butt from a '52 Ford."

** The series' FloatingTimeline in general tends to make every character's past an anachronism stew if viewed in total. Homer, for instance, is supposed to be in his late 30s, and flashbacks usually remain proportionate to whichever year the current episode came out in. But so much time has passed since the series began in addition to so many flashbacks that he's experienced decades of things. Past episodes have depicted him being alive during the Kennedy administration, interacting with record players and black and white [=TVs=], partying during the Moon Landing, going to disco clubs, being a metalhead in TheEighties, etc...

* The setting of ''WesternAnimation/TheAmazingWorldOfGumball'' is a mish-mash of aesthetics and technology dating from TheSeventies, TheNineties, and [[TheNewTens the 2010's]], despite the fact that the series itself is explicitly set in the latter of the three decades.

* The WesternAnimation/BugsBunny cartoon "Prehysterical Hare" begs the question, how ''did'' film exist in B.C. days?

* ''WesternAnimation/TheSuperMarioBrosMovie'' mostly takes place in a fictional world called the Mushroom Kingdom, but parts of it take place in Brooklyn, New York. While in Brooklyn, we see an HDTV displaying an ad with 1980s-style video discoloration, and Mario is shown to have an NES (1980s) and a model Arwing from ''VideoGame/StarFox'' (the first one was released for the Super NES in 1993) in his bedroom. Most references are to 1980s things, but Mario and Luigi own smartphones. A diner with an HDTV also has an arcade machine inspired by ''VideoGame/DonkeyKong'', a 1981 game!

* ''WesternAnimation/TheSimpsons''

* ''WesternAnimation/Primal2019'' features the classic anachronism of [[OneMillionBC cavemen and dinosaurs coexisting]]. Season 2 would go even further and has Vikings, ancient Egyptians, Celts, Romans, Bretons, and others somehow existing at the same time as dinosaurs and cavemen in this universe. The Historical Society also seems to be purely Victorian, but have a stuffed ''Smilodon'', though it could be a replica.

** Two other cartoons also set in OneMillionBC, "Prehistoric Porky" and "Daffy and the Dinosaur" not only show dinosaurs existing alongside large mammals, but show the two coexisting trillions of years ago. Quite an accomplishment, seeing as the Universe is only around 14 billion years old.

** Mr. Burns, similarly, seems to have grown up in a mythical time period that's basically an anachronistic pastiche of various elements of the late 19th and early 20th centuries.

** Played straight in the flashback episode "That 90s Show". It's supposed to take place in the early 1990s when grunge music came onto the scene, but it references pop culture from all over the decade. Homer is seen drinking Zima, which became popular around 1993, watches ''Series/{{Seinfeld}}'' episodes from 1995/96, Franchise/SonicTheHedgehog's design from the 2000s is shown, people are shown browsing the Internet in the early 1990s, and songs from the late 1990s are played. Homer also inspired Music/KurtCobain, which means the episode should've taken place in the late 1980s for that to happen.

* Gladiators of Rome: Despite being placed in 95 AD Rome, Has a character saying ''tweet'' (despite the term tweet didn't exist when Twitter was launched in 2006), Cassio mentioning Goldilocks, A baby chewing bubblegum (Although that bubblegum wasn't invented in the late 19th and early 20th century and babies are too young to chew gum.), A reference to the Balcony scene from Romeo and Juliet (Romeo and Juliet didn't take place in the 14th century and Shakespeare was not born until 1564), Timo singing ''If you're Happy and You Know it'', etc.

--->'''Bart:''' It's like a history lesson come to life!
--->'''Lisa:''' No it's not, it's entirely inacc--
--->'''Bart:''' Quiet, here come the ninjas!

* Both ''WesternAnimation/XMen'' and ''WesternAnimation/WolverineAndTheXMen2009'' portray Japan in a very bizarre light. They acknowledge that the country has modern technology and clothing, but feudalistic ninja are apparently everywhere, and everyone we see is obsessed with the Samurai code of honor.

* Lampshaded in the ''WesternAnimation/PhineasAndFerb'' episode "Doof Dynasty". The episode takes place in 1500s China, and the Candace of this timeline is trying to bust her brothers because their Big Ideas use technology which is way too far ahead of that time.

** When the kids play CowboysAndIndians, Nelson fires with a "Killmatic 3000". Bart tells him they didn't have that back then and Nelson retorts "records from that era are spotty at best."

* ''WesternAnimation/KingOfTheHill'' in the episode "Yankee Hankie", it is implied that Cotton Hill has videotapes of Hank from when he was a young child along with ones of Little Hank. One slight problem - Hank was born in the mid 1960's, years before any form of home recording came onto the scene. In 1970 Sony released the U-Matic system, but it was expensive and it is unlikely Cotton would have bought one, moreover the tapes looked way different than the ones stacked on Cotton's shelves (they were bigger and more like a cartridge). Cartrivision was released around 1972, but it was built in a TV set, was also too expensive and the black and white camcorder attachment wasn't common and was also very expensive. Practical home video recording came in 1977 with Betamax and then VHS, but by then, Hank was a teenager and camcorders for those formats weren't around until the early 80's.
