4KidsTV (often stylized as ‘4K!DS TV’ and originally known as ‘FoxBox’ from 2002 to 2005) is a defunct television programming block and Internet-based video on demand children’s network operated by 4Kids Entertainment.

It originated as a weekly block on Saturday mornings on the Fox Broadcasting Company, which was created out of a four-year agreement reached on January 22, 2005 between 4Kids Entertainment and Fox to lease the five-hour Saturday morning time slot occupied by the network’s existing children’s program block, Fox Kids.
