Something I only just noticed. If you’re watching BBC TV on an analogue set that has teletext, and change channels to BBC1 or BBC2 during the break between programmes, instead of seeing the Ceefax generated “BBC1″ or “BBC2″ it instead shows the name of the next programme. This reverts to the station’s name once the programme has started, but does mean that if you’re idly channel hopping and arrive during a trailer, you know the name of the programme that’s on next. Very clever. It’s probably been around for ages, but today was the first time I’d seen it.
