Kids' WB was Warner Bros.' American children's programming division brand for The WB Television Network. In September 2006, the block moved to The CW Television Network. The CW is the result of The WB's merger with UPN in 2006. The Kids' WB television block was last aired on May 17, 2008, and the Saturday morning programming slot was sold to 4Kids Entertainment to form The CW4Kids (which has since been renamed to Vortexx).
Kids' WB was re-launched as an online network on April 28, 2008, a few weeks before it was replaced by The CW4Kids. The network allows viewers to watch shows of Looney Tunes, Hanna-Barbera and DC Comics. It has different zones where users are linked to Kids' WB, Kids' WB, Jr., and DC HeroZone. It is also available on Fancast featuring full episodes of such TV shows such as Looney Tunes, Scooby Doo, The Flintstones, and The Jetsons.
Even though the US block is now defunct, there are still Kids' WB blocks in Australia and Bulgaria, although they are run separately from the former US block.
