* The very first show on Nickelodeon to have this treatment was ''Series/YouCantDoThatOnTelevision''.
* Before Nicktoons came about, ''WesternAnimation/InspectorGadget'' was Nickelodeon's most-adored cartoon in the 80's. Clips of the show also appeared in some of Nick's promos. ''WesternAnimation/LooneyTunes'' on Nickelodeon was also treated this way.
* The trope was averted for the very ''first'' Nicktoon to hit it big, ''WesternAnimation/TheRenAndStimpyShow''. Because it came before this trope became prominent, it was only seen on Nickelodeon twice a week (on {{SNICK}} and on Sunday mornings). However, it was also run on {{MTV}} at the height of its success. Another likely reason it wasn't given marathon airings was the fact that they had so few episodes to run in the first place.
* ''Series/AllThat'' was the next big live action show for Nick after You Can't Do That On Television.
* ''WesternAnimation/{{Rugrats}}'' was the first Nicktoon to really get this treatment. After the show was UnCancelled due to the ratings for the reruns being high, the show dominated most of the lineup and was running at least four times a day 7 days a week. This led to Nickelodeon using the studio Creator/KlaskyCsupo to produce at least six new shows for the network, including the ''Rugrats'' SpinOff ''WesternAnimation/AllGrownUp'' (born from another over-hyped special, one that got Nickelodeon's highest-ever ratings at the time, with almost twelve million viewers). Meanwhile, all the other Nicktoons were basically ignored or cancelled outright. Though Rugrats was nowhere near as AdoredByTheNetwork back then as ''WesternAnimation/SpongeBobSquarepants'' is now (see below).
* Back in the mid-to-late 90's, ''WesternAnimation/GarfieldAndFriends'' was adored more than any other syndicated show, airing twice a day and getting promoted often.
* ''WesternAnimation/SpongeBobSquarePants'' could be the posterchild for the trope. Since the show was uncancelled, it runs at least ''eight'' times on an average weekday. It will often be the first thing they show in the morning and the last thing they show at night (before turning into NickAtNite), and it's the only show that they run at all different hours of the day to get pre-schoolers, after-school kids, ''and'' evening teenager audiences. "Special" ''[=SpongeBob=]'' episodes are hyped up and promoted more often than the regular Nicktoons on the network. Some days, it gets more airtime than all the other Nicktoons still on Nickelodeon combined. At least during 2009-2011, even ''repeats'' got higher ratings than the average that most kids' shows nowadays have. Go on [[http://www.tvbythenumbers.com TV By The Numbers]], look at the top cable ratings for the weeks and check out how many episodes will be there. However, ratings for the show have lately dropped, probably due to daily overexposure.
** There was a three-day long marathon of nothing but [=SpongeBob=] in 2009 to promote the [[MilestoneCelebration 10-year anniversary]] leading up to the ''Truth or Square'' special. Later during that week, even ''Nick At Nite'' aired a special about the production of the show.
** On 7/18/10, an unannounced twelve hour marathon of ''[=SpongeBob=]'' plagued the channel, before an airing of ''Film/AdventuresInBabysitting''.
** On 7/29/10, of the 11 hours of Nickelodeon not including NickAtNite and Nick Jr, nine hours were filled with ''[=SpongeBob=]'' and ''iCarly'' alone without any of their current Nicktoons showing and only two other shows aired.
** During 2010, the Australian Nickelodeon had ''[=SpongeBob=]'' running from 12AM-6AM every night, for ''over'' a year.
** A schedule change in April 2011 resulted in ''[=SpongeBob=]'' having over '''60''' airings that week.
** The UK Nickelodeon had a '''502''' hour marathon of [=SpongeBob=] in Summer 2011 (that's two hours short of ''three solid weeks'') for the Clash of the Bottom competition, where kids had to vote for their favourite main character. To top that off, it was the UK's second-longest TV show marathon ''of all time'', only being beaten by Boomerang UK's [[Franchise/ScoobyDoo Scooby Summer]].[[note]](The American record belongs to FXX's 2014 marathon of ''WesternAnimation/TheSimpsons'' in its entiriety, including the movie.)[[/note]]
** On July 21, 2012 Nick aired a [=SpongeBob=] marathon to promote the "Super-Spongey Square Games", an hourlong block of new episodes devoted to sports. They also aired the 1-hour special "Truth or Square" and the movie.
** Whenever a new episode is going to be aired (and a ''15-minute one'' at that), Nickelodeon will hype it up with a big marathon and tons of promos that air on Nickelodeon, other Viacom networks, and networks that aren't owned by Viacom! [[note]] though the latter instance may depend on your cable/satellite provider, as some of them overwrite ads to air local commercials or promos for other networks. Make note that Creator/{{CBS}} is no longer part of Viacom[[/note]] That there just shows how much that Nickelodeon absolutely loves [=SpongeBob=].
** Hollywood news website ''Deadline'' reported that in January 2012, ''[=SpongeBob=]'' filled up about a quarter of Nickelodeon's schedule. As of October 2013, the Sponge now accounts for roughly ''45%'' of the network's airtime!
** Nick had a SpongeBob "Win-a-thon" on June 8th, 2014 for no reason, followed by the Nickelodeon premiere of Film/MrMagoriumsWonderEmporium.
** Nowadays, as of 2014, it seems like [=SpongeBob=] is getting fewer and fewer airings. If it keeps up, the show may suffer the same fate as ''Series/WhoWantsToBeAMillionaire'' suffered when ABC treated it the same way for many years.
* ''{{iCarly}}'' spent several years as the adored live action show counter-part to Spongebob. Not surprisingly however, as it was the only show to even come close to matching Spongebob's ratings and popularity, up to and including an episode that broke the 12 million viewers mark. Like Spongebob it got the marathon treatment regularly.
** Nickelodeon does this with any "big" Teen Com that has any form of success -- ''Series/DrakeAndJosh'' comes to mind fairly quickly and they even aired the Christmas special over and over ''even when it wasn't Christmas''.
*** Speaking of ''Drake and Josh'', they also liked playing the "Really Big Shrimp" special a lot. In the mid-2000's, it would air at least once a month.
** Plus, when the network's teen-coms air new two-part specials, after their airing, it'll probably rerun lots of times shortly afterward. When "iStart a Fan War" premiered in mid-November, it aired a total of nine times in the remainder of the month alone. Similarly with "iParty with Victorious", because Nickelodeon went so far as to make an extended version of it.
*** Averted in ''Series/ICarly'''s last year or so. Nick showed first-run episodes without ''any promotion'' at all, and were pushing ''Series/{{Victorious}}'' instead.
** After the premiere of ''Series/SamAndCat'', the network repeatedly promoted reruns of the first episode, using the phrase "See how it all began" as if it hadn't aired just the day before. After two days of this the network dropped all pretenses and announced that it would air the first episode every single day that week.
* Before 2013, ''WesternAnimation/DoraTheExplorer'' used to be the most adored preschool show on Nickelodeon, airing at least four times during the morning hours.
** As of July 2014, this honor now goes to ''WesternAnimation/PawPatrol'', running 4 episodes a day. Dora now only airs once a day.
* Sometimes Nick combines overplayed shows into giant marathons or blocks that can take up entire days:
** On 11/26/10, they played a six-hour ''[=SpongeBob=]'' marathon, followed by an ''iCarly'' marathon at 3, ending with ''iStart a Fan War'' at 7, and wrapped it up with the premiere of the ''Victorious'' special, "Freak the Freak Out".
** On Latin America's channel, almost all weekends are 48 hour marathons of either ''[=SpongeBob=]'' or ''iCarly''.
** As of May 18, 2012, Nickelodeon could be called "The ''Spongebob'' and ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'' Network". The latter would play for 2 1/2 hours on weekdays, making it the second-most run show on Nick.
* ''WesternAnimation/FanboyAndChumChum'': Massive blocks on both Nickelodeon and Nicktoons, It seemed for a while that you couldn't go a single day of the week without seeing at least three episodes of it.
** Often the same [[RuleOfThree three episodes]]. Again and again and again. Seriously, for a while you could only see three to five episodes, total, of ''WesternAnimation/ThePenguinsOfMadagascar'' and ''WesternAnimation/FanboyAndChumChum'', even with the knowledge that other episodes probably existed. They would play them in hour blocks, yet you never seemed to catch a new episode.
* Before it got ScrewedByTheNetwork, ''WesternAnimation/TUFFPuppy'' would get adoration in the same way as ''Fanboy and Chum Chum'', being shoved down our throats when ''[=SpongeBob=]'' has the day off.
* When they had the rights to it, ''[[Anime/DragonBallZ Dragon Ball Z Kai]]'' would be shown on Nicktoons multiple times every day with flimsy excuses for marathons. It's 11/11/11? They promised to show 11 hours of the show. As of 2012 it would run at least 4 episodes a day. However, the rights have since expired and the show is no longer airing on Nicktoons. It moved to Creator/AdultSwim's Creator/{{Toonami}} block in Fall 2014.
* The block-series, ''Nick Studio 10'', was crammed into the program during any possible rerun. It got so bad that Nick actually ''[[https://www.youtube.com/watch?v=y4OVok7cUvU interrupted whatever show is playing]]'' to air a random clip of something and/or a ''Studio 10'' skit instead of waiting for the next commercial break. An irrational PeripheryHatedom developed, and ''Studio 10'' became a rare case of a series seemingly bullied off the air by social media.
* Nickelodeon was extensively advertising ''WesternAnimation/SanjayAndCraig'' when it was new. In fact, ''two'' or even ''three'' commercials for the show would air in a single commercial break. Commercials were even airing on different networks. They've also interrupted shows with ''Sanjay and Craig'' ads as well, playing a commercial ''right'' after a show's theme song. However, it's (thankfully) fitted so no content is missed.
** They went so far as to advertise on Website/{{Tumblr}}, leading to a backlash against the show because Tumblr ads were breaking into the users' dashboard.
* Is today a holiday (Christmas, New Year's, Thanksgiving, etc.) or a [[NoHoperRepeat special event on a different network]] such as the Super Bowl or awards shows like the Grammys, Emmys, Oscars, etc.? Chances are that ''WesternAnimation/{{Rugrats}} in Paris: The Movie'' will be on tonight. The movie is also played every other week as well.
** Before ''Rugrats in Paris'', from 2009-2012, Nickeloden used these same excuses to air the first live-action ''Film/ScoobyDoo'' movie. (Ironically, it's ''Scooby-Doo'', which is normally adored by [[Creator/CartoonNetwork Nick's competitor]]!!!)
** Whenever there's a big [=SpongeBob=] marathon, you can almost always expect an airing of ''WesternAnimation/TheSpongeBobSquarePantsMovie''. Sometimes, they will air it TWO or more times in the same marathon. It was like this during the 10th anniversary marathon, as well as one promoting a new episode. Nowadays it's gotten to the point where they'll play the ''[=SpongeBob=]'' movie just to fill space that they can't fill with more ''[=SpongeBob=]''. No real rhyme or reason, you'll just tune in one day and there it'll be.
** They also adored ''Jinxed'' back in November and December of 2013.
* When it was new, ''WesternAnimation/RabbidsInvasion'' took ''Kung Fu Panda'''s crown as second most run animated series on Nickelodeon. You could expect to see at least 2 hours of it a day.
* For a time at the dawn of TheNewTens, Nickelodeon would greenlight just about anything as a vehicle for Lucas Cruikshank (better known as WebVideo/{{Fred}}). First, they gave him three movies based around his Fred character. Then, they gave Fred a series (despite the fact that none of the movies were that popular, and neither was the series). Then when Nickelodeon canceled all of its sitcoms, they went ahead and gave Cruikshank a new series in the form of ''Series/MarvinMarvin''. [[https://twitter.com/LucasCruikshank/status/350056101502386178 That said, not long after the series ended, so did Cruikshank's relationship with Nickelodeon.]]
* TeenNick can basically be called "The ''Franchise/{{Degrassi}}'' and [[Series/{{Zoey 101}} anything]] [[Series/TrueJacksonVP like]] [[Series/H20JustAddWater it"]] channel.
** Back when TeenNick was still The N, when they first picked up ''One on One'' reruns in early 2006 they began running the show ad nauseam, with the occasional ''Series/{{Degrassi}}'' re-run in the prime time slots and new episodes would air infrequently of their other shows. A year later in spring 2007, The N's line-up was two episodes of ''Series/TheFreshPrinceOfBelAir'', then two episodes of ''One on One'', then two episodes of ''The Fresh Prince of Bel-Air'', then two episodes of ''One on One''. ''Degrassi'' completely disappeared from the schedule, save for re-runs at 3AM on the weekends.
** ''Degrassi'' on [=TeenNick=] is an especially unusual case since Nick[=/=]Creator/{{Viacom}} does not own merchandising rights to the show, and Epitome Pictures makes separate agreements for DVD production.
** ''Degrassi'''s also adored by the Canadian channel Much Music. When a new season starts, all day is given over to the runup to the premiere. This makes a little more sense for them - Degrassi and Epitome's other current production ''TheLAComplex'' are Much's flagship original dramas.
** ''Series/{{Zoey 101}}'' and ''Series/DrakeAndJosh'' re-runs have more or less taken over Creator/TeenNick's entire schedule during the day and early evening. It's to the point that even long-time fans of both shows have expressed annoyance at the shows being played way too much in a given day.
* Creator/NickAtNite was every bit as bad with ''Series/TheGeorgeLopezShow'', probably worse. First, they would run marathons of the show for every occasion imaginable using any excuse they could get, no matter how shoddy. Then they did away with the excuses, and began showing marathons of ''George Lopez'' without even giving an excuse to do so. On multiple occasions, they aired '''over 40 hours''' of it in one week, setting up a bizarre situation -- his self-titled TalkShow on Creator/{{TBS}} often competed with his own old sitcom.
** It got so ridiculous that Nick at Nite decided to celebrate ''Saint Patrick's Day'' (which in America at least is viewed as basically being a day to celebrate Irish heritage) with "Luck of the Lopez" week.
** During the 2000's, the entire Nick at Nite lineup was revamped multiple times and ''Series/TheFreshPrinceOfBelAir'', ''Series/TheNanny'', ''Series/MalcolmInTheMiddle'', and ''Series/FamilyMatters'' have all come and gone....but ''George Lopez'' '''remained untouched in the lineup''' after all this time, despite being arguably less popular than the other shows listed in this sentence!
** As of 2011, MTV Tr3s has gotten in on the ''George Lopez'' overplaying fun now too.
** Also as of 2011, ''Series/{{Friends}}'' has gotten a lot of overexposure since it was added to the Nick At Nite line-up. Now, it's normally an hour of ''FullHouse'', an hour of ''TheNanny'', then about 2 hours of ''Friends'', leaving ''Series/TheGeorgeLopezShow'' to air at 1 a.m. Not to mention ''BET'' airing ''FamilyMatters'' during the day now.
** ''The Nanny'' was also adored by Nick At Nite in 2010. Nick At Nite would play marathons of the show on major holidays, and aired three hours of it a day.
** Creator/NickAtNite loved ''Fresh Prince'' when they had the syndication rights to it. There were several times where they'd show four episodes in one two-hour block. It was also an "introductory" staple for a while, where it would be the first show after the regular Nick schedule ends, possibly to attract a younger crowd.
* After Creator/NickAtNite managed to deal ''Series/TheGeorgeLopezShow'' a similar fate as ''Series/WhoWantsToBeAMillionaire'' in the eyes of many viewers (see [[AdoredByTheNetwork/LiveActionTV this page]], they moved on to ''MyWifeAndKids''.
** Part of what happens with Creator/NickAtNite and TV Land is that when they get the rights to a new show, they always give it something of an introductory marathon to get people into the groove of watching it. They tend to do it with most shows when they first get the rights to them.
* [=NickMom=] really likes to air ''Series/TheNewAdventuresOfOldChristine'', airing nothing but the show for half of the block on weekends.
** Before that, it was ''[=NickMom=] Night Out''; however this case was because most of [=NickMom=]'s starting shows were ruthlessly panned by Nick Jr. viewers, so going into the archives for reruns of mom-centric shows was the best way to salvage the lineup.
* Nick Jr. UK adores ''WesternAnimation/PeppaPig'' to ''[=SpongeBob=]'' levels, airing it at least 15 times a day.
** Before that, they used to love playing anything by [[WesternAnimation/ThomasAndFriends Britt]] [[WesternAnimation/TheMagicAdventuresOfMumfie Allcroft]].
* If you watch Nickelodeon Asia, it's hard not to turn it on and see either ''TeenageMutantNinjaTurtles2012'', ThePenguinsOfMadagascar or BackAtTheBarnyard. These three shows air so much that [[ScrewedByTheNetwork SpongeBob only airs four times a day and only airs older episodes.]]
* As of 2014, ''TeenageMutantNinjaTurtles2012'' seems to be Nick's second-favorite show, after SpongeBob of course.
