As a primary WB affiliate, WLWC aired Kids' WB programming; after the station became a primary UPN affiliate, the block was dropped, as UPN also carried a children's programming block ("Disney's One Too"). Kids' WB was not picked up again after UPN canceled its own children's block in 2003. The block, which was replaced with "The CW4Kids" in 2008, returned to WLWC when the station began airing CW programming. ("The CW4Kids" was renamed "Toonzai" in 2010 and then "Vortexx" in 2012; the block ended in 2014.)
