I'm working on getting clips from each of the shows below.
Back in the day, for those too young to remember, there were only three major networks-ABC,CBS, and NBC. Occasionally you'd run into a local PBS station in the UHF bands, but for the most part, them three was it. Larger markets with multiple stations might offer "13 channels of shit on the TV to choose from" as PINK FLOYD put it, but they were just the same stuff on different channels. Prime time ran from 7:00 P.M. to 11:00 P.M., after which everybody went to bed. Hard as it is to believe now, the list below comprises the entire viewing availability for the entire country in the 1969-1970 season.
