There’s no question I’ve forgotten more of our childhood shows than I remember, but: Romper Room, Captain Kangaroo, Howdy Doody, and Mickey Mouse Club later on. But there were local (Columbus) shows, too, and I should research that.
Edit: Ding Dong School, with Miss Frances!
Earliest evening shows: Jack Benny and probably other comedy/variety shows, Amos & Andy, I Love Lucy, Honeymooners.
A few years later in the mid-1950s it exploded, with sitcoms and detective shows and everything else, but these are my earliest memories. I’m sorry to say I didn’t get into westerns then.
