Brian Eno, the musician, said that someone young trying to discover new sounds online could stumble into something from the 1920s as easily as the 80s, 10s or last week. It's an interesting idea. When I was wandering around in the punk years, I was closer to the big band era than kids now are to Queen or the Beatles.
I thought the Beatles were ancient in 1979. In a way, they were. But now, poor young souls can find that stuff (I am not a Beatles fan) at random online, and if they have no taste, it sounds new and fresh.
TV and media don't seem to work that way. The visual things - technology, fashion, hair, social concerns - they are really evident. I've never been a TV watcher, and when I'm stuck watching shows I'm supposed to know about, they look like time period theatre to me. Some of the stuff people thought was funny isn't anymore - some is.
I'm really glad things are not what they were then. Part of it is I can now see what some of those trends resulted in, and how many people are really upset by change. I don't buy the "Man do you remember the good old days when we all had tuberculosis and feared polio? Good times, good times." But I agree (I think) with
@jaylach that's fun to look at old stuff. I listen more than watch, but music that came out a month ago and music from 80 years ago have a lot to enjoy. If you're into film and TV, it must be similar.
Even our fish have changed....
