Many Western cartoon series have had original runs lasting 65 episodes, because 65 episodes equals 13 weeks (or three months) of material to syndicate at one episode per weekday.

This was typical with cartoons produced for first-run {{syndication}}, and adopted as policy by the Creator/DisneyChannel (which has a similar 65-episode cutoff for its live-action {{Kid Com}}s) and KidsWB, although some syndicated shows did air weekly originally. Nowadays, it is increasingly difficult for cartoons to achieve even this length. This shift is due to a combination of the demise of traditional syndication around the turn of the century, the fact that most networks airing animation order episodes in much smaller numbers due to the increasing fragmentation of television leading to much smaller viewership (and thus lower ad revenue), as well as the poor economy leaving everyone with less money to do anything.

It should also be noted that this trope really only applies to cartoons aimed towards children, rather than Adult cartoons ''WesternAnimation/TheSimpsons'' and its imitators are treated like standard American sitcoms.

!!Renewed after the original 65 episodes:
* ''[[Disney/{{Aladdin}} Aladdin: The Animated Series]]'' originally ran for 65 episodes on the Disney Afternoon Block. [[ChannelHop When picked up for the CBS Saturday morning block]] it was given an additional 21 episodes.
* ''WesternAnimation/AlvinAndTheChipmunks'' is an interesting case, as it was both a first-run syndication, ''and'' a network series at the same time: the first 65 episodes (five standard length seasons, and half of a long sixth season) were produced specifically for syndication, but were also network-broadasted, while the other 39 episodes of the series(the second half of Season Six, and the last two seasons) were not initially included in the original syndication package, and only aired once during the show's original run on NBC (however, international markets do include these 39 episodes).
* The first 65 episodes of ''WesternAnimation/{{Animaniacs}}'' ran on Fox Kids, as did four more episodes cobbled together out of unused segments. Then came the ChannelHop to The WB. The show ended with 99 episodes.
* The ''{{Babar}}'' cartoon is counted as being UnCancelled despite the sixth season being produced ''nine years'' after the fifth season brought it to 65 episodes.
* The original ''WesternAnimation/BatmanTheAnimatedSeries'' season was 65 episodes long. It was continued by a 20 episode second season (under the title ''The Adventures of Batman & Robin'') and two seasons of ''The New Batman Adventures''.
* ''BuzzLightyearOfStarCommand''
* ''WesternAnimation/DennisTheMenace'' had a 65 episode season airing in syndication in 1986. It later got a 13-episode season for CBS Saturday Morning in 1988, bringing the total to 78 episodes.
* ''WesternAnimation/DuckTales'' had 65 episodes for its first season (including the FiveEpisodePilot), then was renewed for two more seasons of 22 and 13 episodes respectively, bringing the total to 100.
* ''WesternAnimation/DarkwingDuck'' also had episodes that ran independent of its TheDisneyAfternoon syndication.
* The first two seasons of ''WesternAnimation/{{Gargoyles}}'' had 65 episodes in all. The third season, retitled ''Gargoyles: TheGoliath Chronicles'', suffered from SeasonalRot and wound up in CanonDiscontinuity.
* ''WesternAnimation/GoofTroop''
* ''WesternAnimation/HeathcliffAndTheCatillacCats'' did 65 episodes in its first season and 21 in its second.
* ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'' originally had 65 episodes, but was successful enough to merit another 65 for a total of 130.
** ''He-Man'''s {{Spinoff}}, ''WesternAnimation/SheRaPrincessOfPower'', was also renewed after 65 episodes, but its total only came to 93.
* ''WesternAnimation/InspectorGadget'' did 65 episodes and was then renewed for an additional 21. The second season replaced the voice cast (Except for Gadget, Brain, and Dr. Claw) due to voice recording moving to Hollywood after being outsourced to Toronto for Season 1 (the characters mentioned were already having their voices recorded in Hollywood).
* ''WesternAnimation/JohnnyTest'', renewed for a fifth (and later sixth) season after the first 4 seasons brought the episode total to 65.
* ''WesternAnimation/KimPossible'', though it had to be UnCanceled to get a fourth season after reaching 65 episodes. Its final total (not counting the movie) is 87 episodes.
* ''{{MASK}}'' had 65 episodes in its first series, which was followed by the short and very different racing series.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' had its 26-episodes per season format halved in season 3 in order to precisely reach the 65 episodes milestone. It was later renewed for a fourth season with the usual 26-episode lineup, bringing the (current) total to 91.
* ''WesternAnimation/PhineasAndFerb'' at least 100 episodes and counting. The opening theme's references to "104 days of Summer vacation" is actually a references to how they only expected the show to have 52 episodes (and thus 104 shorts).
* ''WesternAnimation/PinkyAndTheBrain'' had 65 episodes, not counting a few compilations of their ''WesternAnimation/{{Animaniacs}}'' segments. However, it was continued as ''WesternAnimation/PinkyElmyraAndTheBrain'' for 5 episodes, [[FanonDiscontinuity though just about everyone would like to forget that.]] [[CreatorBacklash Including the writers.]]
* ''WesternAnimation/{{Recess}}'' is a strange case. The series ended with 65 episodes (as per Disney's Rule), but ABC wanted to order more episodes for the 2002-03 series. At the last minute, Disney declined, and three of the episodes were released as the DirectToVideo movie, ''WesternAnimation/RecessTakingTheFifthGrade'' (With one more being released as part of ''Recess: All Growed Down''). Which brings the episode total to 69.
* The original 1991-93 run of ''WesternAnimation/{{Rugrats}}'' lasted 65 episodes, however before they were deciding on what to do with it, they aired the specials between 1995 and 1996, completing the 65 episode run. However, the specials did so successfully, that they considered actually renewing it, instead of cancelling it. Only for it to be officially cancelled in 2004.
* ''SabrinaTheAnimatedSeries'' lasted one season of 65 episodes from 1999 to 2000 (like a number of Saturday morning cartoons) but got a spin-off, ''Sabrina's Secret Life'', in 2003, with twenty-something episodes. Fans [[FanonDiscontinuity like to forget that series]], though.
* The original North American dub of ''Anime/SailorMoon'' by [[Creator/DICEntertainment DiC]] originally aired in a 65 episode package for syndication. Stopping in the middle of the second season, with no real conclusion. Eventually DiC received funding to dub the final 17 episodes of R which were broadcast in Canada. One year later these episodes aired in the United States as The Lost Episodes. Two years after that TOEI's North American Branch Cloverway oversaw the dubbing of 77 additional episodes bringing the total of dub episodes to 159.
* The first ''[[{{WesternAnimation/TeenageMutantNinjaTurtles1987}} Teenage Mutant Ninja Turtles]]'' cartoon {{Channel Hop}}ped to CBS after producing 65 episodes for syndication. The final episode count is 193.
* ''Anime/TenchiMuyo'' originally had 65 episodes (not counting the movies and special) comprising the original Tenchi [=OVAs=] (13 eps), Tenchi Universe (26 eps), and Tenchi in Tokyo (26 eps). It was shown on American TV because of this. However a sequel to the original [=OVAs=] was made years later bringing the count to 72 (73 with the Mihoshi special). If you count the spinoffs, the episode count is now at 112.
* ''WesternAnimation/ThunderCats''
* ''WesternAnimation/TinyToonAdventures'' followed its first syndicated season of 65 episodes with 13 more episodes in syndication and 20 episodes on FoxKids.
* ''WesternAnimation/TheTransformers'': 65 episodes over two season, but after TheMovie the show was renewed for a third season (albeit one that replaced most of the cast who were killed in the movie) that brought the count up to 98.

!!Related Examples:
* ''{{Anime/Robotech}}'': Perhaps one of the most infamous examples, and how many people first heard of the practice. Harmony Gold originally secured the US license to ''Anime/SuperDimensionFortressMacross'' for broadcast and syndication and originally intended to air it alone (even producing a few [=VHSes=] of the standalone show), but the series was only 36 episodes long. The producers felt they ''had'' to have the minimum 65 episodes for syndication (or else the whole project risked financial oblivion), so they also licensed ''Anime/SuperDimensionCavalrySouthernCross'' (23 episodes) and ''Anime/GenesisClimberMospeada'' (25 episodes). 36 + 23 + 25 + 1 extra clip episode (cobbled together to help bridge the narrative gap between the first two sagas) brought the episode total to 85, well exceeding the minimum goal of 65. It also created one of the worst legal snarls in animation history, but, well, [[NoExportForYou/AnimeAndManga that's a tale for another day...]]
