When I was a kid and we had 3 network channels plus PBS, there were a lot of decent shows on - McHale's Navy, Hogan's Heroes, COMBAT!, 12 O'Clock High, Mr. Roberts, Bonanza, Have Gun Will Travel, Johnny Yuma, Dick Van Dyke, Smothers Brothers, Carol Burnett, etc, plus assorted kid fare.
Today with many, many more channels - piles and piles of steaming television crapola.
Movies aren't much better. The local rag just published "2020's Best Movies" with film critics giving their lists of the best 20 or 25 movies of last year; with one or two exceptions I hadn't even HEARD of them, and the few movies I had an interest in seeing (e.g., Greyhound, Wonder Woman 1984) didn't make any of their lists.
