Pebbly, we had one of those and were one of only four familes in the street to have one. When The Lone Ranger came on you couldn't hear yourself speak because of a bunch of screaming kids who had come round to watch.
Nowadays, when I watch football (soccer to you lot on the other side of the pond
) in HD colour on a 3D screen, I'm amazed to think how far and how fast technology has moved on. To think, the UK didn't get it first regular colour transmission until 1968, which if my memory serves me correctly was the tennis at Wimbledon on BBC2.
