>>6426741If you mean like a type of TV show, news and local shows are #1. News was on everyday, sometimes 2-3 times a day in every major city in the US. I think most of it was preserved from the late 70s's on, but that's locked up somewhere never to be seen again.
Soaps are also up there as they ran 5 days a week and at their peak, there were IIRC 10-15 of them.
Sports is up there as well as from the late 70's on, everything mostly exists, but it hasn't been released.
Game shows are also up there as they were dozens on and even some of the less popular ones had hundreds to thousands of episodes.
Wrestling would probably also be up there, but the main problem is that most of the early 80's stuff and before is gone forever, which is real sad. But hey who knows, they say TV signals end up in space and maybe in another 50-100 years, we'll figure some of that out.
