another form of time machine

Time to sit down for a few minutes to read the once-a-year purchased Radio Times. Yes, The Christmas Double Edition. Already into the second week, like the countdown has started back to normality.

A curious aspect has been a glance at today's viewing. It's like a throwback to another era, at least on the main channels (once referred to as the terrestrial channels).

Unless I missed the memo, we seem to be stuck in a time warp. Some examples of the programming:

BBC2 Porridge : comedy prison series from 1976.
BBC2 Morecambe and Wise : comedy show from a long time ago.
BBC2 Top of The Pops Christmas Special : featuring Slade, Wizzard and various other 1970 acts.
ITV1 Agatha Christie's Miss Marple : Apparently this is new? but the main series is from ages ago.
C5 An Audience with Bruce Forsyth : Star of the 1970s+. New, but surely we have had enough over the last 13 weeks of SCD?
ITV2 The Empire Strikes Back : yes, from 1980.
ITV3 Agatha Christie's Poirot : ...you get the idea.

Around this there's a few quiz shows, a couple of 'behind the scenes' Doctor Who programmes and a couple of more recent light-hearted movies. An altogether strange mix of nostalgia and presumably economy programming.

BBC have been plugging Antiques Roadshow's Van Dyke discovery rather heavily, so maybe that's the main option?
