The digital TV channel E4 has been forced to apologise by the broadcasting regulator OFCOM, after accidently screening an advert during a programme break.
A complaint was made following a broadcast in March, when a 30 second advertisment for Admiral Insurance was shown in the gap between Friends and Scrubs.
As well as trails for Glee, the film Reservoir Dogs, cartoon The Cleveland Show and some historic comedies on its website, the channel screened something that could help it pay the bills.
"We just don't know how this happened." E4 spokeswoman Andrea Harris explained. "Usually we just bombard viewers with trails for programmes that we hope they'll watch, just to make us show something else. All I can say is that a full investigation is underway and we wholeheartedly apologise to our loyal viewers for any distress caused."
The apology from the digital broadcaster follows hot on the heels of a similar one from the BBC, after it failed to show a trail for the new series of Dr Who on any channel for a 24 hour period.
