If I think of my childhood years, much of which was in the 1960s, 50 years before that was a post Edwardian era, a time which would have conjured up scratchy gramophone records, women in long dresses and still to get the vote, cinema in it's infancy, flickering non talking fast moving black and white films, pretty incomprehensible! By contrast, I'm wondering if the early 1970s would seem such a world way to a young person today, fashions gone only to return from time to time, music still listened to, a golden age of cinema that gave us masterpieces such as The Godfather. From a technological point of view certainly different days, but the motor car whilst dated at least resembled something we might all be driving today, unlike the very beautiful, exclusive only to the wealthy, cars that would have be driven prior to the Great War, not to mention the very empty roads.
Although having said all that, yes tv from that era does seem dated, probably the most watched series from that time would be "Fawlty Towers" still very funny though. My overall impression watching bygone era tv, is the men wore a lot of dreary looking brown and green clothes and the women a lot of make up, although their eyebrows at least didn't resemble slugs!
