Nicktoons often tend to have this problem with their scheduling:
- All Grown Up!'s fourth season took two years to air. Not just that, but there were 13 months between the airing of that season's premiere and the next episode, and a year between the second and third episode of that season. As well as a 9 month gap between the seventh and eight episodes of the fifth (and final) season.
- Rugrats (1991) wasn't safe from this either. Sure, there were episodes that went on video before airing on TV, other times episodes would take a while to air for no reason.
- The Turkey Who Came To Dinner, the Thanksgiving special was produced in 1997, released on VHS in October of that same year. However, it wouldn't air on TV until November 20, 1998, over a year later on the same day The Rugrats Movie released on theaters
- A batch of Season 6 episodes made in 1999 were held over until airing in 2001. On top of that, the episodes The Magic Baby/Dil We Meet Again (the latter released on VHS first) used the Season 7 opening, despite Kimi not appearing until the second movie.
- While the show finished production in 2002, episodes would still be slowly burned off by airing in segments or with different episodes. The final batch would be aired in Summer 2004, a year after Rugrats Go Wild! hit theaters.
- The Preschool Daze episode that was meant to kick off the short-lived spinoff (despite that being made in 2001) finally made it to air. However, that spinoff wouldn't even see broadcast in the US (until 2008) and be burned off on the direct-to-video specials in 2005/06.
- One of the major reasons for John Kricfalusi's firing from the production of The Ren & Stimpy Show was his inability to complete an episode on time if his life depended on it. This was due to him having such a relentless perfectionism about his work that production often slowed to a crawl as he obsessed over the little details. This was so bad that even the show's second episode was late, forcing Nick to air a rerun in its slot just a week after the series premiered. This continued with Adult Party Cartoon a decade later, where he only managed to produce 3 out of 9 episodes on time.
- Parodied by an episode of The Simpsons (in one of several digs the show made at its then-rival) when one of the nominees for "Outstanding Writing in a Cartoon Series" is the season premiere of Ren and Stimpy. The clip is a title card that reads, "Clip Not Done Yet."
- The Fairly OddParents! was the victim of this. 2011 was supposed to be a year long celebration of its tenth anniversary, with "specials every month and new episodes". By April, nothing of the sort had happened. In addition, FOP was very rarely aired in 2010 and a number of episodes from the seventh season took two years to be aired despite the fact that the season premiere for the eighth season has been aired. It wasn't until 2013 that a new season finally began, and even then, it aired a few episodes until 2014, where new episodes aired that summer.
- The first six episodes of Season 7 (up to Super Zero) were planned for Season 6, but delayed due to the Wishology movie slowing down production of them.
- Hey Arnold!'s last season took 3 years to air (March 2001 to June 2004), and they were also aired Out of Order, creating some continuity confusion.
- In America, the third season of Danny Phantom had a very slow schedule. An episode from the middle of the season was heavily promoted, and aired in late 2006. The episode, titled Urban Jungle, included references to and elements from things that happened earlier in the season, which left viewers largely confused. The rest of the season didn't air until Summer 2007, one year after it aired in Europe and other countries.
- In a similar vein to Danny Phantom, the final season of Avatar: The Last Airbender aired a lot later in America than in Europe and other countries, so all of the plot twists, reveals, etc. were all spoiled on the internet long before the season aired in America.
- The 2012 incarnation of TMNT has run into this a few times. The most notable example would probably be Parasitica, which was said to air a week after "Pulverizer Returns!", but then jumped to June 1st, before changing into June 29th. It finally aired the next month on the 20th. The series also takes breaks around Season 4, generally right after major arcs are concluded; to date, it's the longest-running season of the show, starting in 2015 and going into 2017, whereas the other three had finished their runs before the year had ended.
- Planet Sheen has been a victim of this. It began in 2010 and the first (and last) season didn't finish airing until 2013.
- While most seasons of SpongeBob SquarePants take only a couple of years to finish, season 9 took almost five years to finish airing in America. One of the reasons for the gaps between episodes was due to the production of The Sponge Bob Movie Sponge Out Of Water.
- Season 3 also suffered this to a lesser extent, taking three years (2001-2004) to finish airing in America.
- "Goo Goo Gas" aired on July 19, 2009, long after the rest of Season 5 had finished airing (in fact, this was the same day Season 7 premiered). Its sister episode had already aired 2 years prior.
- The same incident happened earlier with "Gary Takes A Bath" which aired on July 26, 2003, long after Season 2 finished airing and Season 3 started airing. Its longer-than-normal sister episode already aired in March 2001.
- Starting with Season 5, it has become the norm for new seasons to premiere before the previous season has finished airing, which could range from a few months to (in the case of season 6's premiere) years.
- The special event "The Tidal Zone", consisting of five new episodes from SpongeBob and its Spin Offs, was initially scheduled for November 25, 2022. It was even advertised in two Comic Con panels and promoted on social media. There were also going to be weekly premieres of SpongeBob and The Patrick Star Show throughout the month to promote it. However, early that November, all these premieres were silently pulled for the Nickelodeon premiere of The SpongeBob Movie: Sponge on the Run, which had already come out two years earlier. The event eventually premiered on January 13, 2023.
- The Patrick Star Show:
- "Super Sitters" was scheduled for April 22, 2022, but got pulled and replaced with SpongeBob reruns. The episode has had many foreign airings and been released on VOD services, but did not air in the US until April 10, 2023, almost a year after it was supposed to premiere.
- "The Uncredible Journey" was originally scheduled for November 4, 2022, but got pulled and ended up airing on February 10, 2023.
- "Host-a-Palooza" was delayed twice. It went from an initial scheduling of November 4, 2022, to February 10, 2023, to February 17, 2023.
- "Backpay Payback" and "House Hunting" got delayed twice. They went from a scheduled premiere on November 11, 2022, to February 17, 2023. "Host-a-Palooza" premiered on this day instead, so "Backpay Payback" got pushed back a week to February 24, 2023, and "House Hunting" aired on March 3, 2023.
- Season 3 of The Penguins of Madagascar had two year-long gaps between new episodes.
- ChalkZone had a pretty slow schedule. The first episode premiered on December 31, 1999, with the rest of season one to air through 2000. However, Nickelodeon decided to hold the show off until March 22, 2002. Finally in May 2003, the second season finally premiered, even though it was produced a year earlier (though because of the first season being delayed for so long, THAT season ended up airing in Spring 2002 instead. No episodes were produced in 2001 due to the show's staff being unsure whether or not the show was even going to air). While it was also a short season (eight episodes while the average Nicktoon season is roughly thirteen episodes), the episode airdates were spaced farther apart than season one to allow less time for the third season to air. By the time season four aired, Nick's interest in the show had waned and cancelled it right in the middle of the season in June 2005 due to low viewership. Nick decided to air the remainder of the season three years later, in 2008.
- As far as anthology series go, the second season of KaBlam! had Life With Loopy absent for half of the season (only seven of the thirteen episodes that season featured the short, making it the shortest season of the short series). This was due to production on the short moving buildings- season one was produced at Skellington Productions, which was owned by Disney, but they would allow other stop-motion studios to use the building. After season one wrapped up, Disney closed it down after James and the Giant Peach underperformed in the box office. Production moved to Custer Avenue Stages, which was used from season two to the end of the series.
- The Loud House has a case similar to Gravity Falls and Steven Universe (see Western Animation). It originally had a standard new episode once-a-week type of schedule. Following a brief hiatus, however, it now takes about two weeks for new episodes to air. But, similar to the Stevenbombs, they air each new episode all in one week. The most notable case happened with the special "Tripped!", which had its release date changed three times before Nickelodeon moved it to June 25th, 2018. Even worse, Amazon accidentally released the episode on the original airdate before pulling it and Nick still ran promos for the special even after they removed it from their May lineup.
- Speed Racer: The Next Generation is another example of this. The first season had bursts of weekly episodes that were interrupted by hiatuses lasting a month or more (the longest of which lasted for about 4 months). Season 2 was a worst offender, airing roughly two years after the first season. Not only that, but midway through the second season there was a hiatus that lasted 612 days, which happened to occur right after a three-parter with a cliffhanger ending.
- Welcome to the Wayne had an unfortunate case of this. It premiered in July 2017 and went into a Series Hiatus nine episodes and two months later, with a second season announced half a year later. The series returned in Spring 2019, airing the remaining episodes of Season 1 and airing the second seasonnote afterwards, with little to no marketing, and the show disappearing not long later.
