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.

Typical with cartoons produced for first-run UsefulNotes/{{syndication}}, and adopted as policy by the Creator/DisneyChannel (which has a similar 65-episode cutoff for its live-action {{Kid Com}}s) and Creator/KidsWB, although some syndicated shows did air weekly originally. Disney would end up dropping the format after fans complained about the cancellation of several popular shows, such as ''WesternAnimation/KimPossible'', which would lead to it getting another season.

Some people consider this a form of ScrewedByTheNetwork, especially if the show they like are at the receiving end of this trope. It should also be noted that this trope really only applied to cartoons aimed towards children, rather than Adult cartoons ''WesternAnimation/TheSimpsons'' and its imitators are treated like standard American sitcoms.

This practice became drastically less common near the end of the TurnOfTheMillennium, as American cartoon production has essentially abandoned broadcast syndication (at least domestically) in favor of programming exclusive to specific cable networks (or even streaming services). Still, some networks continue to cut their shows off at 65 episodes, either for foreign syndication, own network re-runs, or force of habit.

See also TwelveEpisodeAnime and BritishBrevity -- both of which should remind fans of any of the shows listed here of how lucky they actually are -- and FiveYearPlan. For some shows that went well past 65, see MilestoneCelebration.

As a side note, if one wants to binge watch a whole 65-episode series in one sitting, and each episode is assumed to be exactly 22 minutes long, then you would be watching almost an entire day's worth of that show. (22 minutes per episode times 65 episodes equals 1,430 minutes, which is 23⅚ hours or 23 hours and 50 minutes.)

!!Retired at 65:
* ''WesternAnimation/OneHundredAndOneDalmatiansTheSeries'': 65 episodes with one short first season (the OneSaturdayMorning episodes), and one ''long'' second season (WesternAnimation/TheDisneyAfternoon episodes)

* ''WesternAnimation/TheBatman'': 65 episodes over five seasons.
* ''WesternAnimation/BatmanTheBraveAndTheBold'': 65 episodes over three seasons. The plot of its final episode blatantly jabbed at the fact the show was DenserAndWackier than most ''Batman'' incarnations and CutShort in favor of introducing the DarkerAndEdgier ''WesternAnimation/BewareTheBatman'' to take its place, which, ironically, only made it to 26 episodes.
* ''WesternAnimation/BeverlyHillsTeens'': 65 episodes over one season.

!!Renewed after the original 65 episodes:
* ''WesternAnimation/AladdinTheSeries'' 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.
* ''WesternAnimation/{{Arthur}}'': The first three seasons produced between 1996-1998 totalled 65 episodes. The show then went on a one-year hiatus in 1999 before its popularity resulted in the show being renewed (and subsequently, becoming a LongRunner).
* The ''WesternAnimation/{{Babar}}'' cartoon is counted as being UnCancelled despite the sixth season being produced ''nine years'' after the fifth season brought it to 65 episodes.
* ''WesternAnimation/BatmanTheAnimatedSeries'' was 65 episodes long for its first season on Fox Kids. It was continued by a 20-episode second season (under the title ''The Adventures of Batman & Robin'') on the same network. The follow-up series, ''The New Batman Adventures'', [[ChannelHop which aired on WB Kids]], is often shown in reruns as additional episodes to the original series, resulting in 24 more episodes for a total of 99.
* ''WesternAnimation/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 WesternAnimation/TheDisneyAfternoon syndication.
* ''WesternAnimation/DragonTales'' had 40 episodes for its first season and 25 for its second season, though "Just the Two of Us / Cowboy Max" was considered a "lost" episode. There was an unproduced pilot and a musical special. After a gap of well over two years, it was announced that third season of episodes would air.
* ''Literature/{{Franklin}}'' had 65 episodes in it's first 5 seasons, with 13 episodes each. The sixth one had an extra 13 episodes, totaling 78.
* The first two seasons of ''WesternAnimation/{{Gargoyles}}'' had 65 episodes in all. The third season, retitled ''Gargoyles: The Goliath Chronicles'', suffered from SeasonalRot and wound up in CanonDiscontinuity, save for the first episode "The Journey" which was reformatted for the later comic books anyway.
* ''WesternAnimation/GIJoe'' had two [[FiveEpisodePilot mini-series]] and a single 55 episode season that initially amounted to 65 episodes, but the second season extended that to 95 episodes. The series eventually concluded with 100 episodes with an edited version of ''G.I. Joe: The Movie'' that was split in five parts.
* ''WesternAnimation/GoofTroop'' had 65 episodes which aired in syndication alongside a 13-episode season made for Saturday mornings on ABC.
* ''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 (counting the movie as three single episodes) is 87 episodes.
* ''WesternAnimation/{{MASK}}'' had 65 episodes in its first series, which was followed by the short and very different racing series.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' - The show had 26 episodes for each of its first two seasons, and 13 for its third season in order to meet syndication. The show became so popular and profitable that it was renewed each year for an additional 26 episode season. As of October 2017, Season 7 has finished, with Season 8 being slated to air in 2018, bringing the total to at least 195 episodes.
* ''WesternAnimation/PhineasAndFerb'' Ended at 138 episodes,[[note]]140 if you included the ''OWCA Files'' special that was produced as part of the series, but billed as a standalone[[/note]] making it Disney's second longest-running animated series after ''WesternAnimation/MickeyMouseClubhouse''. 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). Interestingly, the first two seasons together make 65 episodes.
* ''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 Creator/{{ABC}} wanted to order more episodes for the 2002-2003 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 1991-1993 run of ''WesternAnimation/{{Rugrats}}'' lasted 65 episodes. They then aired specials between 1995 and 1996. However, the specials did so successfully that they actually renewed the show instead of cancelling it. The show was only cancelled in 2004, but not before being spun off into WesternAnimation/AllGrownUp which lasted another 4 years.
* ''WesternAnimation/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 total episodes for syndication.[[note]]The FivePartPilot aired in 1987, then a year later 13 additional episodes aired in weekly syndication, followed by 47 more in 1989.[[/note]] 13 additional episodes were produced for Syndication in 1990, in addition to the first 26 episodes on CBS. 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 episodes), and Tenchi in Tokyo (26 episodes). 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 Creator/FoxKids.
* ''WesternAnimation/TheTransformers'': 65 episodes over two seasons, 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 95, followed by the 3-part "The Rebirth" series finale.

!!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 intended to air it alone (even producing a few [=VHS=] releases 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...]]
* During the [[TurnOfTheMillennium early-to-mid 2000s]], Warner Bros. actually had a trend of pulling the plug on shows that reach ''52'' episodes. Shows like ''WesternAnimation/BatmanBeyond'', ''WesternAnimation/JusticeLeague'', ''WesternAnimation/StaticShock'', ''WesternAnimation/XiaolinShowdown'', ''WesternAnimation/XMenEvolution'' all ended at 52 despite high ratings. [[note]]Though Justice League was revived with a sequel series, ''Unlimited.''[[/note]] ''The Batman'' and ''Teen Titans'' both proved popular enough to warrant one extra season and reached 65 episodes. Interestingly enough, ''WesternAnimation/JackieChanAdventures'' was the one show during this period that [[SubvertedTrope managed to surpass both benchmark]] thanks to 26 standalone episodes in its second season (a few of which factored into the plot for Season 3).
* Disney also has a trend of retiring short series after two seasons. ''Tasty Time With [=ZeFronk=]'', ''Lou and Lou Safety Patrol'', ''A Poem Is...'', ''Nina Needs To Go!'', ''As The Bell Rings'', ''Shorty McShort's Shorts'' and ''Take Two With Phineas and Ferb'' have all suffered this fate. The only exceptions to this are the ''[[WesternAnimation/MickeyMouse2013 Mickey Mouse]]'' shorts and ''Choo Choo Soul''.
* In the late 1990s, the minimum amount of episodes a syndicated show could have was now 40. Usually after those 40 episodes, the show would be cancelled. Examples of this include ''[[Series/CaptainKangaroo The All-New Captain Kangaroo]]'', ''WesternAnimation/BuzzLightyearOfStarCommand''[[note]]which technically was syndicated to Creator/{{UPN}} stations- Disney and UPN having made a deal in 1999 to carry a spinoff of ''Disney's Main/OneSaturdayMorning'' called ''Disney's One Too'', which lasted until 2003[[/note]], ''WesternAnimation/LibertysKids'', ''WesternAnimation/TheThreeFriendsAndJerry'' and the original syndicated version of ''Anime/{{Pokemon}}''. Britt Allcroft had intended to sell ''Series/ShiningTimeStation'' and ''WesternAnimation/MagicAdventuresOfMumfie'' into syndication with 40 episodes each,[[note]]although the former had 75 and the latter had 39, but would have 40 counting ''[[ChristmasEpisode Mumfie's White Christmas,]]''[[/note]] but after a meeting with Haim Saban, the shows wound up airing on the then-new [[Creator/ABCFamily Fox Family Channel]].
* '' WesternAnimation/TheRealGhostbusters'' had a 65-episode season that aired on weekdays in syndication alongside the second season of Saturday morning episodes on ABC.
* ''WesternAnimation/JonnyQuestTheRealAdventures'' was originally announced as a 65-episode series, but production was cut back to 52 episodes.
* ''WesternAnimation/ThunderCats2011'' was going to last 65 episodes, but it was axed after 26 episodes.
* ''Series/MightyMorphinPowerRangers'' (a live-action show) was initially intended to run for only 40 episodes, with these episodes using most of the fight footage from its source material ''Series/KyoryuSentaiZyuranger'', a 50-episode series. However, the unexpected popularity of the show led to the first season being extended to 20 additional episodes, just 5 episodes short of the 65-episode quota. These additional episodes featured all new MonsterOfTheWeek footage (known among fans as [[FanNickname Zyu2 footage]]) filmed by Creator/{{Toei}} specifically for ''Power Rangers'' after Creator/{{Saban}} exhausted most of the usable ''Zyuranger'' footage.[[note]]Originally Toei filmed 25 episodes worth of monster footage in order to meet the 65-episode quota, but only 15 of these ended up being used in the end of Season 1 due to leftover ''Zyuranger'' footage that were not adapted for the initial episodes and one of the monster being used for a two-parter. The remaining 10 monsters ended up being used for the first 13 episodes of Season 2[[/note]] Ultimately the show exceeded the 65-episode quota and lasted two more seasons (spanning a total of 155 episodes) by adapting the giant robot/monster footage from the [[Series/GoseiSentaiDairanger two]] [[Series/NinjaSentaiKakuranger succeeding]] Franchise/SuperSentai shows before following Sentai's tradition of producing a new series every year. The Franchise/PowerRangers franchise now spans over 800 episodes.
* ''WesternAnimation/TheAngryBeavers'' was set to run for 65 episodes, but the final episode (Bye Bye Beavers) never finished production precisely because of a scene in which Norb [[NoFourthWall breaks the fourth wall]] and reveals to Dag that they're characters in a cartoon show on its final episode, which broke a Creator/{{Nickelodeon}} rule at the time in which a show must never have a definite ending. A voice-over recording of the controversial segment was later leaked online (which can be heard [[https://youtu.be/cPP4zUDuo4c here]]).
* ''WesternAnimation/BeavisAndButthead'' was initially picked up for 65 episodes by Creator/{{MTV}} according to the documentary on the DVD sets, although it is unclear if this meant 65 or 130 shorts, as two shorts compose a half-hour program. At any rate, the initial run lasted 160 episodes in its original 15-minute format (80 half-hour programs), before switching to a 10-minute format for its final season consisting of 39 episodes (13 half-hour programs) and the finale, which is a full half-hour episode, for a total of 200 episodes and 94 half-hour programs. The 2011 revival series consists of 24 15-minute episodes or 12 half-hour programs.
