4Kids TV (often stylized as 4K!DSTV and formerly known as FoxBox from September 14, 2002 to January 15, 2005) was an American television programming block and Internet-based video on demand children's network operated by 4Kids Entertainment.

[7][8] On November 10, 2008, 4Kids Entertainment announced that 4Kids TV would conclude at the end of the year due to intervening conflicts between Fox and 4Kids, as the latter company had not paid the network for the time lease for some time, while the network was unable to maintain the guaranteed 90% clearance for the block due to affiliate refusals and an inability to secure secondary affiliates to carry the programming in markets where the Fox station denied clearance for the block.

Fox would reverse course and indirectly resume airing children's programming for the first time since 4Kids TV ended through an agreement announced on December 17, 2013, when it signed a deal with Steve Rotfeld Productions to launch Xploration Station, a two-hour block of live-action educational programs focused on the STEM fields, which debuted on September 13, 2014.

As the block accounts for two of the three weekly hours of educational programming required by the Federal Communications Commission's Children's Television Act, the Fox affiliates that opted against airing 4Kids TV, Fox Kids, or Weekend Marketplace (including those owned by the network that were acquired through its 1996 merger with New World Communications and those acquired through that deal that were owned by Tribune Broadcasting, now Nexstar Media Group) elected to run Xploration Station as it is an E/I-compliant lineup syndicated primarily to the network's affiliates, relieving them of taking on the full burden of purchasing educational programming aimed at children from the syndication market (although some Fox stations, including those owned by the Sinclair Broadcast Group—the vast majority of its stations had carried Fox's previous children's blocks, decided to decline the block anyway due to existing commitments to syndicated programs compliant with Children's Television Act recommendations).

In the event that a Fox affiliate or in some cases, an O&O of the network—opted not to carry 4Kids TV, the block then became available for the local broadcast rights to be acquired by another television station.

Some of 4Kids TV's programming (such as Winx Club, The Adrenaline Project, Magical DoReMi, Stargate Infinity, reruns of Back to the Future: the Animated Series, and Cubix) met the criteria to be considered educational and informational under the requirements defined by the Children's Television Act, and counted toward the three-hour-per-week mandatory educational children's programming quotas outlined by the Federal Communications Commission.

Note: These CW affiliates ran 4Kids TV on Sundays, due to their obligation to carry their primary network's children's lineup on Saturday as scheduled.
