The WB Television Network (known simply as "The WB") was an American broadcasting television network owned by Warner Bros. and Tribune Broadcasting which first launched on January 11, 1995. The network ran for eleven years before merging with UPN to form the CW in 2006. Popular programming on the WB included Buffy the Vampire Slayer, Roswell (both of which would move to UPN), 7th Heaven, Supernatural (both would continue on the CW, or in the case of 7th Heaven, have reruns issued there), and Dawson's Creek. The network also included the children's programming block, Kids' WB, which would air on Saturday mornings and weekday afternoons. It would later move to the CW following the WB's closure. Its mascot was Michigan J. Frog, a singing frog from some Looney Tunes shorts.
