One thing that irks me, although I'm more used to it now, is at the start of the ad break some fool says, "And next on (whatever) is,", and goes on to mention a programme. When I first encountered it I thought that the end of the last programme seemed odd, as if something had been missed off. Then I realised they were just lying to us. On next, after the ads, was the next part of the programme I was watching. The programme they were talking about wasn't on until later that evening.
