Kids' WB was relaunched as an online network on April 28, 2008, a few weeks before the television block was replaced by The CW4Kids. Until it was discontinued on May 17, 2015, the service allowed viewers to stream live-action and animated content, including those from Looney Tunes, Hanna-Barbera and DC Comics. The website operated in different zones based on programming type: Kids' WB, Kids' WB Jr. (for shows aimed at younger children) and DC HeroZone (for action-oriented animated series). It was also available on Fancast featuring Looney Tunes shorts, and full episodes of television series such as Scooby-Doo, The Flintstones, and The Jetsons.

Kids' WB also continues to exist in the form of branded program blocks that air on television in Australia and Bulgaria.


Early years

Kids' WB debuted on The WB Television Network on September 9, 1995, airing on Saturday mornings from 8:00 a.m. to 11:00 a.m. and weekdays from 4:00 p.m. to 5:00 p.m. (the block was structured to air in all time zones, airing on a tape delay outside of the Eastern Time Zone, to adjust the recommended airtime of the block to each zone, and thus during its first five years an exact timeslot for its programs was not announced on-air). On September 7, 1996, the Saturday block was extended by one hour, airing from 8:00 a.m. to Noon Eastern Time.

Although the Kids' WB block aired on almost all of The WB's affiliated stations (including those later affiliated with The WB 100+ Station Group), the network's Chicago affiliate WGN-TV – owned by The WB's co-parent, the Tribune Company – declined to carry the weekday and Saturday blocks in order to air its weekday and Saturday morning newscasts (the first incarnation of the latter was later cancelled in 1998) and other locally produced programming (such as The Bozo Super Sunday Show) in the morning hours, and syndicated programming in the afternoons; Kids' WB programming instead aired on WCIU-TV. However, WGN's superstation feed carried the block when it carried The WB's programming from 1995 to 1999 to make the network available to markets without a local affiliate. WGN-TV began clearing Kids' WB on its Chicago broadcast signal in 2004, taking over the local rights from WCIU-TV.

On September 1, 1997, a weekday morning block was added from 7:00 a.m. to 8:00 a.m. and the weekday afternoon block was extended by one hour, running from 3:00 p.m. to 5:00 p.m. However, WGN's superstation feed, as well as some WB affiliates, had to wait until the next day, as they preempted the blocks to carry The Jerry Lewis MDA Labor Day Telethon. Some WB affiliates (such as WPIX in New York City, KTLA in Los Angeles and KWGN-TV in Denver, Colorado) aired the weekday morning block in conjunction with the weekday afternoon block, extending it to three hours, running from 2:00 p.m. to 5:00 p.m. On the same date, the block received an on-air rebranding – which included a revised logo and graphics package centered upon the Warner Bros. Studios lot theme that was also used in promotions for The WB's primetime programming during the network's first eight years on the air – which was developed by Riverstreet Productions, and lasted until 2005.

Changes at Kids' WB

On February 13, 1999, Kids' WB made a breakthrough when the English dub of the anime series Pokémon by 4Kids Entertainment moved to the network from broadcast syndication. It became a major hit for the programming block,[2] helping it beat Fox Kids with its animated block backed by Warner Bros.[3] Other anime shows aired on Kids' WB in later years, such as Cardcaptors, Yu-Gi-Oh!, Astro Boy, Megaman NT Warrior and Viewtiful Joe.

Toonami on Kids' WB, discontinuation of weekday morning block

In July 2001, Kids' WB's afternoon lineup was rebranded Toonami on Kids' WB, extending the Cartoon Network action-cartoon brand Toonami to broadcast television, and bringing shows such as Sailor Moon, Dragon Ball Z and The Powerpuff Girls to broadcast network television. In addition, non-action programming such as the live-action children's horror anthology series The Nightmare Room were also aired on the Toonami block. The Toonami name was dropped from the afternoon block in June 2002. On September 3, 2001, the Kids' WB weekday morning block was discontinued, with The WB giving that slot back to its local affiliates to carry locally produced shows, syndicated programming and/or infomercials.

Weekday afternoon block ends run, makes way for Daytime WB

On May 31, 2005, The WB announced that the weekday afternoon Kids' WB block would be discontinued "at the request of the local affiliates", as it became financially unattractive due to the fact broadcast stations perceived that children's programming viewership on afternoon timeslots had gravitated more towards cable networks – these stations began to target more adult audiences with talk shows and sitcom reruns in the daytime. Kids' WB's weekday programming continued, but with redundant programming and theme weeks until December 30, 2005 (the block began to increasingly promote Cartoon Network, their afternoon Miguzi block, Hi Hi Puffy AmiYumi and the Kids' WB Saturday morning lineup during the transition). The weekday afternoon Kids' WB block aired for the last time on December 30, 2005, and was replaced on January 2, 2006, by "Daytime WB", a more adult-targeted general entertainment block featuring repeats of sitcoms and drama series formerly seen on the major networks. As a result, the Saturday morning Kids' WB lineup that remained was extended by one hour on January 7, 2006, running from 7:00 a.m. to Noon, no longer affected by time zone variances.

Move to The CW

On January 24, 2006, Warner Bros. Television (producer of Kids' WB and owner of the block's original broadcaster from 1995 to 2006, The WB) and CBS Corporation (owner of UPN and subsidiary of National Amusements who also owns film studio Paramount Pictures' parent company Viacom) announced that they would shut down both The WB and UPN and then merge them into The CW, which would primarily feature programs aired by its two soon-to-be predecessor networks as part of its initial lineup.[4] The combined network utilized The WB's scheduling practices (inheriting the 30-hour weekly programming schedule that the network utilized at the time of the announcement) and brought the Kids' WB block, still run by Warner Bros. Television and maintaining the same name, to the new lineup (The CW's decision to use The WB's scheduling model was mainly due to the fact that it included children's and daytime programming blocks that were not offered by UPN, which had not aired any children's programming since the Disney's One Too block was discontinued in August 2003). Notably, during this time AOL-then a sister company to Warner Bros.-was the main sponsor of CBS' own Saturday morning block KOL Secret Slumber Party, but at no point did either Kids' WB or SSP advertise each other's programs-most likely because SSP's shows were produced by DiC Entertainment and aimed at girls, as opposed to the boy-centric Kids' WB.

The end, rebirth, and second end of Kids' WB

On October 2, 2007, The CW announced that it would discontinue the Kids' WB programming block through a joint decision between corporate parents Time Warner and CBS Corporation, due to the effects of children's advertising limits and cable competition; the network also announced that it would sell the five-hour Saturday programming slot to 4Kids Entertainment.[5] The Kids' WB block aired for the final time on May 17, 2008 (for some stations that aired the block on a day-behind basis, the block's last airdate was on May 18, 2008).

On May 24, 2008, 4Kids launched The CW4Kids in place of Kids' WB. The lineup for the block consisted of 4Kids-produced shows, such as Chaotic, as well as new seasons of Yu-Gi-Oh! and Teenage Mutant Ninja Turtles.[6] The official site,, officially launched on April 20, 2008. The block was renamed Toonzai on August 14, 2010, it was replaced by Vortexx (programmed by Saban Brands) on August 25, 2012, and it continued to air until it ended on September 27, 2014, the new and current block that currently airs in place of four previous blocks aired on The CW is One Magnificent Morning, an E/I block which debuted on October 4, 2014.

Kids' WB returns as streaming service along with The WB

On April 28, 2008, Warner Bros. Entertainment announced that The WB and Kids' WB brands would be relaunched as online networks, with the Kids' WB network consisting of five subchannels: Kids' WB! (for WB shows for kids and families), Kids' WB! Jr. (for shows for younger children), Scooby-Doo, Looney Tunes and two different websites of DC Kids: DC and DC (for action-oriented animated shows for DC fans).[7][8][9] After the dissolution of In2TV, the Kids' WB online portal absorbed most of that service's children's programming. The service was significantly scaled back in 2013, with most of the archival content being removed. The archival content can be easily accessed through the Internet Archive's Wayback Machine.

Split into WB Kids Sites, re-merger into WBKids GO!

The site was split into 3 websites on May 17, 2015. These sites are:, and All three are grouped into WB Kids Sites. The decision to split the site into three ended, after almost twenty years, the use of the "Kids' WB!" brand name. In July 2016, 2 of the 3 websites re-merged into "WBKids GO!". remains active.
