The CITV kids show Art Attack is understood to have been dropped by the channel.
The show has been running for 18 years, has won three Baftas in that time. The Media Merchants, set up by the show's presenter Neil Buchanan and now owned by Hit Entertainment, produces the programme.
According to Broadcast, the programme is one of several shows that have not been recommissioned which also includes Grizzly Tales for Gruesome Kids and Jungle Run.
CITV has also reduced its hours at the weekends, to allow for ITV4 to broadcast, and ITV says, to accommodate sporting events such as the Tour de France, though the changes are to remain in place.
ITV executive chairman Michael Grade has also indicated that it was unlikely it would be investing more money in the kid's channel, saying it did not make "commercial sense."
