Very true Graham but I think repeats would have been welcomed then-especially when you got five minutes of Pink Floyd inserted into a high brow Arts program shown around midnight on a rainy Sunday. Only the weirdos like me got to see it at all
. There was no attitude of "not another repeat" either because there were hardly any. Dad's Army is now a feature on "live" TV. Ironically, those repeats are endlessly popular even though you can source them by all the multiple means you outlined. Human nature I suppose!
