Televised media has a habit of drawing in people's nostalgia whether we like it or not. Yes as times it is soothing, at others just confusing. Now when I see something from long ago I think, 'well really?; haven't we moved on from that one already?' or, 'Has funding for the monetary effort for releasing new commercials dried up along with street ads?'.
If I want or need a bit of the old times, I just look for programmes that say The 100 greatest moments from.. whichever decade, and decide whether or not the moment still actively applies or not. How times have differed offer little or no importance or improvement on ideas, maybe later constructive or early models can pave the way.
What time offers is an increased sense of ill fate or de'ja vu that whatever is happening, is either going to boost your spirits, your sense of morale or conduct, or enhanced persona towards whatever seems to be taking up resonance in whatever form is taking place. I'm not so sure people would want to remember a time in their lives, that maybe wasn't so great and having to see old repeat performances that their sub or pre conscious mind would be better off without.
