During the 2004 look, Boomerang UK once had a technical fault between a run of Tom & Jerry. What was meant to be an ad break, ended up with just a black screen for about a minute, then it went into intermission, with approximately 3mins of bumpers before cutting back to the title card for Jerry and the Lion.
Also, I heard somewhere they had the same advert mix-up with Kinder. Instead of Kinder Surprise, they ran a Bueno advert, where the bar/wrapper is flirting with a human.
But this is what i don't get. They're a kids channel, yet they show all these adult adverts in the mix. and by adult, I mean stuff like mortgages, gas companies, over-50 plans. Are parents really gonna notice these during a kids show?
