Kids' WB! is a former label of Warner Bros., and a defunct children's programming block that aired the Pokémon anime's English dub starting with "The Problem with Paras". Before Pokémon moved to Kids' WB! it was aired via broadcast syndication. The cartoon block kept airing Pokémon until Pasta La Vista!, the last episode dubbed into English by 4Kids Entertainment and the only Pokémon USA production aired on the block was The Mastermind of Mirage Pokémon. Originally Kids' WB had aired the series on Cartoon Network, a similar network owned by the same company. After The Mastermind of Mirage Pokémon, Kids' WB! announced that The WB would drop all anime programming due to The WB and UPN merging to create The CW. This meant a new home for the children's block. On October 2, 2008 The CW announced that they would turn the block over to 4Kids Entertainment who would name it The CW4Kids. However the children's programming block was relaunched along with The WB into online networks.
On April 28, 2008, Kids' WB, alongside The WB, relaunched as online networks.
