In 2005, then Fox-owned UPN stations decreased weekday cartoons to one hour. In January 2006, The WB network's Kids' WB block was relegated to Saturday mornings only after the conclusion of their weekday cartoon block on December 30, 2005, which had replaced the two hours of network programming time on weekday afternoons with Daytime WB, a two-hour block of sitcom and drama reruns; which continued after The WB ceased operations (along with UPN) in September 2006, and were replaced by The CW (owned by both networks' respective parents, WarnerMedia and CBS Corporation) with that block being renamed The CW Daytime. That fall, Fox's UPN affiliates, which became owned-and-operated station of the News Corporation-owned MyNetworkTV, dropped cartoons from their weekday schedules, with some stations only running an educational children's program each day to meet E/I requirements.
