and Disney Channel, and would sell the programming rights to the network's Saturday morning block to 4Kids Entertainment (which at the time of the announcement, had produced a competing children's programming block, 4Kids TV, for Fox). Kids' WB ended its run on May 17, 2008 (though some CW affiliates that delayed the block to Sundays, such as Atlanta affiliate WUPA, aired the block for the last time on May 18). The following week on May 24, 4Kids took over responsibility for The CW's Saturday morning children's lineup, with the debut of a new block called The CW4Kids. The block's lineup initially consisted mostly of programs carried over from Kids' WB, before eventually adding 4Kids-produced shows such as Chaotic as well as new seasons of Yu-Gi-Oh! and Teenage Mutant Ninja Turtles. The block was rebranded into Toonzai on August 14, 2010 (though The CW4Kids name was retained as a sub-brand to fulfill branding obligations that the network had to comply with per 4Kids Entertainment's contract to lease The CW's Saturday morning timeslots); Toonzai ended its run on August 18, 2012. On July 3, 2012, Saban Brands and Kidsco Media Ventures, affiliates of Saban Capital Group, entered into an agreement to program the five-hour Saturday morning time slot with a new action-adventure and comedy programming block for The CW. TheCW4Kids/Toonzai was replaced by Vortexx on August 25, 2012, featuring programs such as Power Rangers Lost Galaxy and WWE Saturday Morning Slam, the latter of which marked the return of WWE programming to the network since WWE Smackdown moved to MyNetworkTV in 2008. On June 5, 2014, The CW announced an agreement with Litton Entertainment to program a block of live-action series designed to comply with the FCC's educational programming guidelines. Vortexx (which was the last remaining non-educational children's block on the major U.S. broadcast networks) was replaced by One Magnificent Morning on October 4, 2014. The block features a mix of wildlife and lifestyle-themed programs, similar in vein to those featured on the Litton-produced blocks aired by ABC and CW sister network CBS (one of its initial programs, Expedition Wild, was moved over to "One Magnificent Morning" from the ABC block; while one of the CW block's early entries, Rock the Park, moved to "Litton's Weekend Adventure" after one season). On January 7, 2016, The CW and Litton announced a five-year renewal for the block, extending it through the 2020–21 broadcast season.
