I watched old reruns, movies, etc., growing up--stuff that was created before (and sometimes WELL before) my generation. I knew celebrities/personalities like Milton Burle, Louis Armstrong, etc., whose careers had diminished by the 70's and were not featured much on television, etc.
This was before the internet. This was the time when cable started expanding nationwide. This was the age when the newspaper industry was at its peak. This was an era when a kid, growing up in rural America, had access to only 4 television channels and was lucky to get NBC on a good day and watched PBS when I was extremely bored.
Maybe my experience is not typical but I KNEW tons of celebrities/personalities growing up. Could tell anyone who they were, what they did, why they were popular, etc. Nowadays? In a time of massive information overload due to internet, 10 billion tv channels, streaming services, social media platforms, etc.? I highly doubt a respectable percentage of young people are knowledgeable of celebrities/personalities histories and careers tens years prior to them becoming self-aware.
That is an unfair generalization. I know people my own age just as blissful of history. Yes, it is hypocritical thinking it but it also amazes me how often I ask younger people about folks like Tim Conway and they have no clue whatsoever. However, ask what a Kardashian ate for lunch and you can determine their caloric intake for the meal.
Whatever.
