Kids' WB

Kids' WB (stylized as Kids' WB!) was an American children's programming brand of The WB that aired on the network from September 9, 1995, to September 16, 2006. The block moved to The CW (a result of the merger of The WB and UPN), where it aired from September 23, 2006, to May 17, 2008. After the block was discontinued, its Saturday morning programming slot was sold to 4Kids Entertainment and replaced by its successor block, The CW4Kids (later renamed Toonzai).

An online network version of Kids' WB launched on April 28, 2008, but closed on May 17, 2015. The service allowed viewers to stream content, such as 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, where it featured Looney Tunes shorts and full episodes of television series such as Scooby-Doo, The Flintstones, and The Jetsons.
