replacing Fox Kids, which the network announced it would discontinue as a result of the 2001 purchase of Fox Family Worldwide by The Walt Disney Company (which resulted in much of the content featured on the block, including those produced by Fox Kids Worldwide part-owner Saban Entertainment, being absorbed into Disney's syndication unit Buena Vista Television).
However, Fox's standards and practices department still handled content approval and responsibility of editing the series to meet broadcast standards.
The online network was shut down on November 2, 2012.
The block had a somewhat unusual relationship to the Fox network.
The programming block aired on Saturday mornings in most areas of the United States, though some stations carried it on Sundays (often due to scheduling conflicts resulting from the block airing on stations affiliated with other minor networks that had their own children's program blocks which competed with Fox Box/4Kids TV, including the Kids' WB on The WB and later The CW, and for its first year, the Disney's One Too block on UPN).
In October 2007, 4Kids Entertainment announced it would program a competing Saturday morning lineup for The CW; the new block, The CW4Kids (later renamed Toonzai, with the original name becoming a secondary brand), debuted on May 24, 2008, replacing the Kids' WB programming block, which had been carried over to The CW from one of its predecessors, The WB, when it launched in September 2006.
DS TV" and originally known as Fox Box from 2002 to 2005) is a defunct television programming block and Internet-based video on demand children's network operated by 4Kids Entertainment.
