Overview: T4 was a scheduling slot on Channel 4 and E4. It also aired on weekdays in the school holidays. The slot had a separate station identification on screen graphic from Channel 4 and E4. The logo of T4 is noticeably the top right segment of the standard Channel 4 logo. Channel 4 originally produced the strand in-house until 2002, when production was passed onto independent companies. The slot is targeted at the 16-34 age group. Until 25 March 2012, T4 aired on Channel 4 both Saturday and Sunday, however, to make way for the introduction of Sunday Brunch in March 2012, T4 Sunday was moved to run on E4; T4 Saturday remained on Channel 4, and some programmes that previously appeared within the T4 block, such as The Simpsons, remained on Channel 4 on Sunday afternoons. On 12 October 2012, Channel 4 announced that they would be axing T4 at the end of December 2012. The show ended on 29 December 2012.
