When I was a kid in the 70's in Newcastle nobody had cable or satellite TV and wouldn't really start getting hooked up until the late 80's. But on the council estate where my grandmother lived, they had something called Rediffusion. What this meant was that you had a dial on your wall, like this:
And that was your "remote." This was back in the days before everyone had a remote, so it seemed quite luxurious to be able to reach over to the wall to change channels instead of having to walk over to the TV. Of course if your sofa wasn't anywhere near the wall, it was six and two threes. I don't think all the positions on the dial were TV - some of them were radio stations. I certainly don't remember my gran having any more than the 3 terrestrial TV stations available by antenna at the time. It was basically the same crap everyone else got but through a wire and hence better signal quality. I guess back then, not having to adjust an aerial was considered luxury.
But yeah, visits to granny's house were like stepping into the future because of that TV dial on the wall, how sad
