A couple of days ago, I was watching BBC 4, which was showing the group Slade at the BBC. But I was watching on Freeview and the signal was bad. It kept disappearing or breaking up, with the sound stuttering. It depended on weather conditions and so didn't happen all of the time. When it did, most of the digital channels vanished leaving a No Signal sign on screen.
I commented to the friend I was watching with that when I'd watched Slade back in the 1970s, I didn't think that the televisions then would be better than what I was watching 40 years in the future on digital. I'd thought that the television of the future would be advanced and sophisticated but in reality it was worse.
