1999 ended up being a turning point for the block, one factor being that many of its competitors were either dying off or becoming shells of their former selves. Creator/{{UPN}}'s block, UPN Kids, never managed to gain as much traction due to a weaker catalog of programs and airing exclusively on Sundays, which would leave it discontinued by that September. The remains of what was once WesternAnimation/TheDisneyAfternoon had finally disintegrated due to the block becoming an afterthought and the syndication market for children's programming fading away, allowing for Kids' WB! to expand its weekday afternoon block by another hour. It would still face some competition on the Saturday morning side, as Creator/{{Disney}} had bought out Creator/{{ABC}} and launched [[Creator/OneSaturdayMorningAndABCKids One Saturday Morning]], though it wouldn't matter after a major game-changer on WB's end. Meanwhile, Fox Kids was starting to struggle due to problems with the ill-fated [[Creator/{{Freeform}} Fox Family]] network, the aftermath of the Fox/New World debacle, the conclusion of network darlings ''WesternAnimation/BobbysWorld'', ''WesternAnimation/XMenTheAnimatedSeries'', and ''WesternAnimation/SpiderManTheAnimatedSeries'', the growing presence of cable networks such as Creator/{{Nickelodeon}}, Creator/CartoonNetwork and a newly-relaunched Creator/DisneyChannel and the beginning of ''Franchise/PowerRangers''' SeasonalRot. During all of that, Kids' WB! picked up a little syndicated show called ''[[Anime/PokemonTheSeries Pokémon]]'', the move of which caused the franchise's popularity in the West to reach ''monolithic'' levels. Ratings started overtaking the competition that year, and its popularity, combined with the strength of its DC cartoons (in particular ''WesternAnimation/BatmanBeyond'' and ''WesternAnimation/StaticShock''), additional anime series like ''Anime/YuGiOh'', and the expansion of its Saturday morning block by another hour, boosting it up to a total of five hours (which they kept for the remainder of its run), firmly established it as the premier children's destination for broadcast TV. Two years later (on the same day, in fact), One Saturday Morning would be rebranded as [[Creator/OneSaturdayMorning ABC Kids]] and Fox Kids would fold around the same time and be replaced by the [=FoxBox=], which was programmed by Creator/FourKidsEntertainment (the company behind the dubs of ''Pokémon'' and ''Yu-Gi-Oh'').

Sadly, like with its competitors, reality started to catch up to Kids' WB! as children increasingly flocked to cable, which often aired children's programming on a 24/7 basis, or at least a decent time period when children are awake. In addition, Warner Bros. Animation started prioritizing Cartoon Network for its premier output, including ''WesternAnimation/JusticeLeague''[[labelnote:*]]Which had its premise and tone saved because it aired on Cartoon Network, as the higher-ups at Kids' WB! wanted to tailor the show to younger audiences in contrast to the previous Franchise/DCAnimatedUniverse shows, leading to one pitch for the block starring younger superheroes and the main Justice League members serving as mentors[[/labelnote]], ''WesternAnimation/TeenTitans'' (which actually aired reruns on Kids' WB! for a while), ''WesternAnimation/DuckDodgers'', and ''WesternAnimation/KryptoTheSuperdog'' (also aired on the block, but for E/I requirements), while more and more of the block's remaining hits would jump ship to that channel, with Kids' WB! being shoved in the wayside during a time when the overall WB network was facing rating problems. The content that was airing on the block during this period was divisive, to say the least. ''WesternAnimation/MuchaLucha'', ''WesternAnimation/XiaolinShowdown'', ''Anime/MegaManNTWarrior'', and ''The Batman'' all had their fans but were seen as [[ToughActToFollow failing to live up to their '90s-early '00s peers]]. On the other side of the coin, ''WesternAnimation/DaBoomCrew'', ''WesternAnimation/LoonaticsUnleashed'', and ''WesternAnimation/CoconutFredsFruitSaladIsland'' were all considered the nadir of the block's content and showed just how far-gone the block was. The weekday block was discontinued in December 2005, and shortly thereafter, the WB announced it would merge with [=UPN=] (which had long given up on children's programming for several years) to form the CW, with Kids' WB! joining the new network. None of the block's anime programming made the jump; future ''Yu-Gi-Oh!'' series (along with reruns of the original show) moved over to the [=FoxBox=]'s successor [=4KidsTV=], while ''Pokémon'' became a full-time Cartoon Network program after years of reruns.

Kids' WB! launched on September 9, 1995, nearly eight months after The WB's launch, and was meant primarily to compete against Creator/FoxKids, who had utterly dominated the children's television space throughout much of the decade. Once thew new block launched, WB's first response to this was to take back many of the shows they produced for that block and move them over to the new block. Unlike Fox Kids, Kids' WB! only programmed a full hour of programming during the weekday afternoons and three hours during Saturday mornings. It wasn't until the premiere of ''WesternAnimation/SupermanTheAnimatedSeries'' in 1996 that the Saturday block was extended to four hours. In Chicago, WB affiliate WGN-TV chose not to carry the block due to commitments to its newscasts, meaning it aired on then-independent station WCIU instead[[labelnote:*]]However, WGN's superstation feed aired Kids' WB programming alongside the entire WB network schedule for markets that didn't have a standalone WB affiliate until October 1999, following the launch of The WB 100+ Stations Group[[/labelnote]]; it wasn't until 2004 that WGN-TV started carrying the block.

The [[SaturdayMorningCartoon Saturday-morning]] and weekday afternoon children's programming block on Creator/TheWB (and Creator/TheCW for its first one-and-a-half years), which deserves special mention as being not only the longest-running Saturday-morning block in television history but also the only block of its kind to outlive the channel it was created for. Programmed in-house by Creator/WarnerBros[='=] television division, it served primarily as an outlet for Creator/WarnerBrosAnimation works, but it also aired programming from third-party studios.

[[BrokenBase Not everyone was pleased about it]], though. With Pokemon's popularity came the push for the block to focus more on action series and anime of equal footing. This certainly wasn't helped by Time Warner's recent merger with [[UsefulNotes/TedTurner Turner Broadcasting]] leading to the decision to have airings of ''WesternAnimation/LooneyTunes'' now be restricted to Cartoon Network once the block's ''Big Cartoonie Show'' and [=ABC=]'s final run of the long-running ''[[WesternAnimation/TheBugsBunnyRoadRunnerShow Bugs Bunny & Tweety Show]]'' both came to an end. Fans of ''Animaniacs'', as well other Creator/StevenSpielberg[=-=]produced WB cartoons such as ''WesternAnimation/{{Freakazoid}}'' and ''WesternAnimation/PinkyAndTheBrain'', felt ''Pokémon'' and ''Yu-Gi-Oh!''[='=]s popularity had cannibalized WB's in-house productions due to the fact that it was cheaper to just license the shows and give them multiple time slots than produce their own shows if it didn't bring in similar ratings, [[WordOfGod a notion later confirmed by Tom Ruegger decades later]]. In addition, Kids' WB! eventually also began losing interest in DC cartoons after ''WesternAnimation/TheZetaProject'' failed to impress, and as the block's main shows started to feature younger protagonists in contrast to the "adults in suits" the main DC shows focused on. ''WesternAnimation/TheBatman'' and ''WesternAnimation/{{Legion of Super Heroes|2006}}'' ended up being the last original DC cartoons for the network, premiering two and four years respectively after ''Zeta Project''[='=]s end and staying until the block itself closed.

Sadly, like with its competitors, reality started to catch up to Kids' WB! as children increasingly flocked to cable, which often aired children's programming on a 24/7 basis, or at least a decent time period when children are awake. In addition, Warner Bros. Animation started prioritizing Cartoon Network for its premier output, including ''WesternAnimation/JusticeLeague''[[labelnote:*]]Which had its premise and tone saved because it aired on Cartoon Network, as the higher ups at Kids' WB! wanted to capture younger audiences leading to one pitch for the block starring younger superheroes and the main Justice League members serving as mentors.[[/labelnote]], ''WesternAnimation/TeenTitans'' (which actually aired reruns on Kids' WB! for a while), ''WesternAnimation/DuckDodgers'', and ''WesternAnimation/KryptoTheSuperdog'' (also aired on the block, but for E/I requirements), while more and more of the block's remaining hits would jump ship to that channel, with Kids' WB! being shoved in the wayside during a time when the overall WB network was facing rating problems.

[[labelnote:*]]From the 1995-96 season, which recycled the second opening from Fox Kids' ''Merrie Melodies Starring Bugs Bunny & Friends''.[[/labelnote]], ''Bugs 'N' Daffy'' [[labelnote:*]]From the 1996-97 season, not to be confused with the similarly titled anthology series on Creator/CartoonNetwork. Incidentally, this incarnation of the show was made around the same time as Time Warner's 1996 merger with [[UsefulNotes/TedTurner Turner Broadcasting]], which allowed the show to feature both the Warner-owned post-1948 cartoons and the Turner-owned pre-1948 cartoons starting in the 1997-98 season.[[/labelnote]], or ''The Daffy Duck Show'' [[labelnote:*]]A temporary Saturday-morning series made for the 1996-97 season as a way to promote the newly-released ''Film/SpaceJam''. It [[Main/ExactlyWhatItSaysOnTheTin featured at least two]] [[WesternAnimation/DaffyDuck Daffy Duck shorts]] out of the usual three Looney Tunes shown, none of which featured WesternAnimation/BugsBunny.

!!1996

* ''WesternAnimation/{{Captain Planet|and the Planeteers}}'' (Mostly the episodes from seasons two and three, the last two seasons of the original Creator/{{DiC}} series, and season four, the first of Creator/HannaBarbera's ''New Adventures of Captain Planet'' series. Season one was never shown and seasons five and six were only shown on international channels.)
* ''The New Batman/Superman Adventures'' (A package series that combined ''Superman: The Animated Series'' with a revamped version of ''WesternAnimation/BatmanTheAnimatedSeries'' known as ''The New Batman Adventures'' that [[TimeSkip took place a few years after the original series]]. Reruns of the original were also shown.)

* ''WesternAnimation/SamuraiJack'' (Aired as a one-off, possibly in response to premiering on Creator/CartoonNetwork earlier that month, which had premiered the weekly ''Kids' WB Spotlight Show'' a day prior.)
* ''WesternAnimation/TheMummyTheAnimatedSeries''
* ''Series/TheNightmareRoom'' (The first live-action show ever to air on the Kids' WB line-up and SpiritualSuccessor to ''Series/{{Goosebumps}}'', though it didn't last long.)
* ''WesternAnimation/RescueHeroes: Global Response Team'' (Previously aired on Creator/{{CBS}}.)
* ''Anime/DragonBallZ'' (Aired for about a week as a part of the ''Kids' WB Toonami''. Ironically when the block became Toonzai down the line, the [[Anime/DragonBallZKai Kai]] series lasted longer.)
* ''Anime/SailorMoon'' (Same situation as ''Dragon Ball Z''. The show was intended for a two-week test run to see how well the show would fare on the block before being pre-empted halfway through for coverage of the September 11th attacks.)[[labelnote:*]]The show also appeared much earlier on the network via its original syndicated run in certain regions.[[/labelnote]]

* ''WesternAnimation/ThePowerpuffGirls1998'' (Reruns from Creator/CartoonNetwork though a few episodes from the fourth season did premiere on the network before their Cartoon Network airing. It was only aired to promote ''WesternAnimation/ThePowerpuffGirlsMovie'' at the time.
* ''WesternAnimation/MuchaLucha''

* ''WesternAnimation/TeenTitans'' (Airing simultaneously on Creator/CartoonNetwork.)
* ''WesternAnimation/XiaolinShowdown''

By the 2007-2008 season, signs were starting to point towards the writing on the wall: ''The Batman'', ''WesternAnimation/{{Legion of Super Heroes|2006}}'', ''WesternAnimation/ShaggyAndScoobyDooGetAClue'' and ''WesternAnimation/TomAndJerryTales'' were all announced canceled, and only two shows, ''WesternAnimation/TheSpectacularSpiderMan'' and ''WesternAnimation/WorldOfQuest'', were slated to premiere mid-season. In October 2007, The CW announced a four-year deal with [=4Kids=] Entertainment to take over the five-hour slot beginning in the summer of 2008, which would also kill off [=4KidsTV=] come that December. Kids' WB! aired its last broadcast on May 17, 2008, with its successor, [=The CW4Kids=] (later re-branded as Creator/{{Toonzai}}) launching the following week; shows that weren't canceled, including ''Spider-Man'' (which premiered two months before the block closed) and ''WesternAnimation/JohnnyTest'' finished their seasons in the new block's inaugural season before moving to other networks that fall; ''The Spectacular Spider-Man'' would eventually find a new home at the newly-formed Creator/DisneyXD, while ''Johnny Test'' jumped ship to, of course, Cartoon Network, where it would be infamously AdoredByTheNetwork until its conclusion six years later.

1999 ended up being a turning point for the block, one factor being that many of its competitors were either dying off or becoming shells of their former selves.

Meanwhile, with Fox Kids starting to struggle due to problems with the ill-fated [[Creator/{{Freeform}} Fox Family]] network, the aftermath of the Fox/New World debacle, the conclusion of network darlings ''WesternAnimation/BobbysWorld'', ''WesternAnimation/XMenTheAnimatedSeries'', and ''WesternAnimation/SpiderManTheAnimatedSeries'', the growing presence of cable networks such as Creator/{{Nickelodeon}}, Creator/CartoonNetwork and a newly-relaunched Creator/DisneyChannel and the beginning of ''Franchise/PowerRangers''' SeasonalRot, Kids' WB! picked up a little syndicated show called ''[[Anime/PokemonTheSeries Pokémon]]'', the move of which caused the franchise's popularity in the West to reach ''monolithic'' levels. Ratings started overtaking the competition that year, and its popularity, combined with the strength of its DC cartoons (in particular ''WesternAnimation/BatmanBeyond'' and ''WesternAnimation/StaticShock''), additional anime series like ''Anime/YuGiOh'', and the expansion of its Saturday morning block by another hour, boosting it up to a total of five hours (which they kept for the remainder of its run), firmly established it as the premier children's destination for broadcast TV. Two years later (on the same day, in fact), One Saturday Morning would be rebranded as [[Creator/OneSaturdayMorning ABC Kids]] and Fox Kids would fold around the same time and be replaced by the [=FoxBox=], which was programmed by Creator/FourKidsEntertainment (which dubbed ''Pokémon'' and ''Yu-Gi-Oh'').

Ratings started overtaking Fox Kids that year, and its popularity, combined with the strength of its DC cartoons (in particular ''WesternAnimation/BatmanBeyond'' and ''WesternAnimation/StaticShock'') as well as additional anime additions like ''Anime/YuGiOh'', firmly established it as the premier children's destination for broadcast TV. Kids' WB would expand its weekday afternoon block by another hour, with the Saturday block expanded to five hours (which they kept for the remainder of its run), and Fox Kids would fold two years later and be replaced by [=FoxBox=], programmed by Creator/FourKidsEntertainment (which dubbed ''Pokémon'' and ''Yu-Gi-Oh'').

[[BrokenBase Not everyone was pleased about it]], though. With Pokemon's popularity came the push for the block to focus more on action series and anime of equal footing. This certainly wasn't helped by Time Warner's recent merger with [[UsefulNotes/TedTurner Turner Broadcasting]] leading to the decision to have airings of ''WesternAnimation/LooneyTunes'' now be restricted to Cartoon Network after the block's ''Big Cartoonie Show'' and Creator/{{ABC}}'s final run of the long-running ''[[WesternAnimation/TheBugsBunnyRoadRunnerShow Bugs Bunny & Tweety Show]]'' both came to an end. Fans of ''Animaniacs'', as well other Creator/StevenSpielberg[=-=]produced WB cartoons such as ''WesternAnimation/{{Freakazoid}}'' and ''WesternAnimation/PinkyAndTheBrain'', felt ''Pokémon'' and ''Yu-Gi-Oh!''[='=]s popularity had cannibalized WB's in-house productions due to the fact that it was cheaper to just license the shows and give them multiple time slots than produce their own shows if it didn't bring in similar ratings, [[WordOfGod a notion later confirmed by Tom Ruegger decades later]]. In addition, Kids' WB! eventually also began losing interest in DC cartoons after ''WesternAnimation/TheZetaProject'' failed to impress, and as the block's main shows started to feature younger protagonists in contrast to the "adults in suits" the main DC shows focused on. ''WesternAnimation/TheBatman'' and ''WesternAnimation/{{Legion of Super Heroes|2006}}'' ended up being the last original DC cartoons for the network, premiering two and four years respectively after ''Zeta Project''[='=]s end and staying until the block itself closed.

Speaking of Cartoon Network (which was owned by WB sister outlet Turner Broadcasting, who had actually taken over The WB's operations in 2001, continuing to do so until two years later), a majority of the shows featured on the block, particularly ones that were nearing or already out of their first-run, would slowly find their way to that channel as early as 1997, either airing in their entirety or through spotlight blocks and experimentations. In fact, some of WB's children's programs that were originally on Fox Kids, such as ''WesternAnimation/{{Beetlejuice}}'' (which was wrapping up reruns on Nickelodeon) and ''WesternAnimation/TazMania'' had skipped Kids' WB! entirely in favor of Cartoon Network. There was also an even bigger attempt at synergy by attempting to brand the late-afternoon weekday block under the Creator/{{Toonami}} name, temporarily airing two of the original block's most iconic shows, ''Anime/DragonBallZ'' and ''Anime/SailorMoon'', while some of Kids' WB's own shows, like ''Superman: The Animated Series'', ''[[Manga/CardcaptorSakura Cardcaptors]]'', and ''Batman Beyond'' would begin airing on the actual Toonami block. Viewers and critics panned it, and the rebranding was dropped after just one year. It produced one original program, ''Literature/TheNightmareRoom'', which got solid reviews but lasted for only 13 episodes, and was the only live-action show ever aired on the block.

Sadly, like with its competitors, reality started to catch up to Kids' WB! as children increasingly flocked to cable, which often aired children's programming on a 24/7 basis, or at least a decent time period when children are awake. In addition, WB Animation started producing more shows for Cartoon Network, including ''WesternAnimation/JusticeLeague'', ''WesternAnimation/TeenTitans'', ''WesternAnimation/DuckDodgers'', and ''WesternAnimation/KryptoTheSuperdog'' (though reruns aired on Kids' WB! for E/I requirements), with Kids' WB! being shoved in the wayside during a time when the overall WB network was facing rating problems. The overall content that was airing on the block during this period was divisive, to say the least. ''WesternAnimation/MuchaLucha'', ''WesternAnimation/XiaolinShowdown'', and ''Anime/MegaManNTWarrior'' all had their fans but were seen as [[ToughActToFollow failing to live up to their '90s-early '00s peers]]. Meanwhile, ''WesternAnimation/DaBoomCrew'', ''WesternAnimation/LoonaticsUnleashed'', and ''WesternAnimation/CoconutFredsFruitSaladIsland'' were all considered the nadir of the block's content and showed just how far-gone the block was. The weekday block was discontinued in December 2005, and shortly thereafter, the WB announced it would merge with Creator/{{UPN}} (which had long given up on children's programming for several years) to form the CW, with Kids' WB! joining the new network. None of the block's anime programming made the jump; future ''Yu-Gi-Oh!'' series (along with reruns of the original show) moved over to [=FoxBox=] successor [=4KidsTV=], while ''Pokémon'' became a full-time Cartoon Network program after years of reruns.

By the 2007-2008 season, signs were starting to point towards the end of the block: ''The Batman'', ''WesternAnimation/{{Legion of Super Heroes|2006}}'', ''WesternAnimation/ShaggyAndScoobyDooGetAClue'' and ''WesternAnimation/TomAndJerryTales'' were all announced canceled, and only two shows, ''WesternAnimation/TheSpectacularSpiderMan'' and ''WesternAnimation/WorldOfQuest'', were slated to premiere mid-season. In October 2007, The CW announced a four-year deal with [=4Kids=] Entertainment to take over the five-hour slot beginning in the summer of 2008, which would also kill off [=4KidsTV=] come that December. Kids' WB! aired its last broadcast on May 17, 2008, with its successor, [=The CW4Kids=] (later re-branded as Creator/{{Toonzai}}) launching the following week; shows that weren't canceled, including ''Spider-Man'' (which premiered two months before the block closed) and ''WesternAnimation/JohnnyTest'' finished their seasons in the new block's inaugural season before moving to other networks that fall; ''The Spectacular Spider-Man'' found a new home at Creator/DisneyXD, while ''Johnny Test'' jumped ship to, of course, Cartoon Network, where it would be infamously AdoredByTheNetwork until its conclusion six years later.

The closures of Kids' WB! and 4KidsTV, along with degradation of [[Creator/OneSaturdayMorning ABC Kids]] (which would shut down three years later) were among the last signs that the decades-long tradition of Saturday-morning cartoons was not long for this world. Toonzai was later folded in 2012 as a result of the gradual collapse of 4Kids Entertainment and would be replaced by Creator/SabanBrands' Creator/{{Vortexx}} block, which would ultimately be the final Saturday morning block, [[Creator/KidsClick outside of a short return in 2017]]. The Kids' WB! name was repurposed as a website featuring the ''WesternAnimation/LooneyTunes'' shorts, the Creator/HannaBarbera library, and the Creator/DCComics-based cartoons. In 2013, the website's shows were scaled back heavily, and after The WB website shut down in 2013 as well, it was euthanized in May 2015 and has since been replaced by the similarly titled ''WB Kids GO!''.

The Saturday-morning and weekday afternoon children's programming block on Creator/TheWB (and Creator/TheCW for its first one-and-a-half years), which deserves special mention as being not only the longest-running Saturday-morning block in television history, but also the only block of its kind to outlive the channel it was created for. Programmed in-house by Creator/WarnerBros[='=] television division, it served primarily as an outlet for Creator/WarnerBrosAnimation works, but it also aired programming from third-party studios as well.

Kids' WB! launched on September 9, 1995, nearly eight months after The WB's launch, and was meant primarily to compete against Creator/FoxKids, who had utterly dominated the children's television space throughout much of the decade. Unlike Fox Kids, Kids' WB! only programmed a full hour of programming during the weekday afternoons and three hours during Saturday mornings. It wasn't until the premiere of ''WesternAnimation/SupermanTheAnimatedSeries'' in 1996 where the Saturday block was extended to four hours. In Chicago, WB affiliate WGN-TV chose not to carry the block due to commitments to its newscasts, meaning it aired on then-independent station WCIU instead[[note]]However, WGN's superstation feed Kids' WB programming alongside the entire WB network schedule for markets that didn't have a standalone WB affiliate until October 1999, following the launch of The WB 100+ Stations Group[[/note]]; it wasn't until 2004 that WGN-TV started carrying the block.

The block had a laxer standards and practices department than Fox Kids, which allowed for darker and raunchy material to air. ''WesternAnimation/{{Animaniacs}}'' took advantage of this upon its move from Fox, with the show amping up its BitingTheHandHumor at an even stronger level than even the Fox days. Creator/BruceTimm noted that when ''WesternAnimation/BatmanTheAnimatedSeries'' was revived by the network, they got only "two paragraphs of stuff we can't do" as opposed to the "five single-spaced pages of notes" that Fox gave them during the original series' run.

* AdaptedOut: Some of WB's children programs from the late 80s and early 90s, such as ''WesternAnimation/{{Beetlejuice}}'', ''WesternAnimation/TazMania'' and ''Series/{{Kidsongs}}'' never aired on Kids' WB due to existing agreements with other networks (''Nickelodeon'', ''Fox Kids'' and ''PBS Kids'' respectively, with the former two both eventually airing on Creator/CartoonNetwork). Not to mention that the former two shows had already ended production and the latter was aimed at pre-schoolers. Later on, two WBA series produced for Cartoon Network, ''WesternAnimation/JusticeLeague'' and ''WesternAnimation/DuckDodgers'', were similarly denied runs on the block.
