Kids' WB (stylized as Kids' WB!) was an American children's programming service and brand of The WB Television Network that aired on the network from September 9, 1995 to September 16, 2006, before moving to The CW (which was created by CBS Corporation and Time Warner as a replacement for both The WB and UPN), where it aired from September 23, 2006 to May 17, 2008. At that point, the Kids' WB block was discontinued, and its Saturday morning programming slot was sold to 4Kids Entertainment and replaced by successor block The CW4Kids.
