Examples relating to SpongeBob SquarePants are on their own page.
- The channel used to have a tradition of airing nonstop marathons of their Nicktoons during the Thanksgiving weekend between the mid 90s to the 2000s.
- The channel marathoned Avatar: The Last Airbender prior to the premiere of the third season.
- Nickelodeon had a short marathon block in 1999, with different episodes of Nick shows airing, but with a similar theme. It was known as 101% Whizbang! With Henry & June.
- It was replaced with UPick in very late 1999, with Henry and June hosting until the block's demise in 2000. You voted for the show you wanted online, and they'd show a little marathon of it or something. (UPick returned in '02, but with live action hosts every weekday, unlike the Henry and June one, which was Fridays.)
- Nickelodeon BENELUX aired marathons of Spongebob Squarepants on weekdays, but they now also have given other shows a marathon, such as The Penguins of Madagascar and Fairly OddParents.
- After it became popular, Nickelodeon began to show The Loud House marathons. One noteworthy example is the "Lincoln Loud's Ultimate Year End Countdown-a-thon", an annual marathon counting down the best episodes of the show aired that year.
- They even aired a marathon to build hype for the premiere of The Astronauts on November 13, 2020.
- Nickelodeon now runs up to compilations of their animated shows as time filler that would count as this trope. All of these are centered around a certain theme. For example, one of the SpongeBob ones consisted of episodes about karate, and the ones for PAW Patrol focus on different characters.
- PAW Patrol:
- Nickelodeon loves doing marathons of the show as much as they love marathons of SpongeBob. Usually, this is to lead up to new episodes of the show, and is sometimes done to premiere episodes of other shows on the blocks. Like Teen Titans Go!, they have held marathons just because it was Friday note and have even held marathons to compete with other network's shows on days that weren't Friday. For example, the week Mickey and the Roadster Racers premiered note , the Nick Jr. block comprised of nothing but PAW Patrol reruns.
- The Italian Nick Jr. channel showed nothing but
PAW Patrol for the first week of May 2017. - On June 28, 2020, an all-day marathon was run on the Nick Jr. channel.
- Nick Jr. ran two different marathons for Valentine's Day 2020. The block on Nickelodeon played one of Bubble Guppies to promote a new episode, while the channel showed one of Peppa Pig.
- On President's Day week of 2022, both the Nick Jr. channel and Nick Jr. block ran marathons of PAW Patrol for most of the day.
- Nick Jr. Too in the UK, a channel that usually airs different programming to the main Nick Jr., occasionally rebrands into Nick Jr. PAW Patrol for a month, airing nothing but PAW Patrol. The same is done for Peppa Pig.
- The week that PAW Patrol: The Mighty Movie came out, the Nick Jr. block had an "Every Pup Ever" marathon showing every single episode of the show.
- From November 18, 2023 to November 19, 2023, the Nick Jr. channel ran an all-weekend marathon of PAW Patrol and Rubble & Crew to promote the release of PAW Patrol: The Mighty Movie on Paramount+.
- When The Rugrats Movie was about to premiere in theaters, Nickelodeon ran a Rugrats marathon called the Rugrats Runnin' Wild Marathon to give fans a chance to tape the show before it was temporarily pulled off the air as a stunt to get more viewers to see the movie.
- On July 7, 2007 (7/7/07), Nickelodeon ran an all-day marathon of Fairly OddParents, topping it off with a special, "77 Secrets of the Fairly OddParents Revealed", and an airing of Channel Chasers. This is one of the few days since SpongeBob SquarePants started airing on weekly basis since July 2001 that the sponge was nowhere near the main channel's schedule (which won't happen again until January 2021).
- Due to the nature of modern cable television, since mid/late 2021, Nicktoons and Teen Nick have started airing marathons on a weekly basis now (such as Casagrandes/current sitcoms marathon every weekend). Even the Nick Jr channel (which was never reliant on marathon running in the past unless if it was for the special occasion) has started relying on marathons as well, which means even more Paw Patrol, Peppa Pig and Blaze and the Machines reruns. This is at the expense at airing ended shows, which never seem to air nowadays due to their irrelevance.
