I remember growing up in the 80’s and 90’s, but still having a lot of knowledge about shows from the 60’s and 70’s and even earlier. Today I feel young people only really know about stuff from their generation. This is in spite of the fact that they have the internet and can look up older stuff easily. I think part of it has to do with the fact that back in the day reruns of old shows use to run alongside new stuff creating kind of a continuity between old and new. Today you have to actually seek out old stuff, so most people don’t bother.
