I,also, watched Sesame Street in the early 70’s.
However, once I entered kindergarten, became a latch key kid and had free access to the TV without adult supervision, I discovered the world of TV reruns,especially the one with James West and Artemus Gordon who could never tame that evil dwarf.
I too watched it as a young tike in the early 70’s.
It was not nearly as corrosive as it is today.
Of course it could not match the attraction to me of more adult fare like Star Trek, Green Acres and Hogan’s Heroes.
WWW, Perry Mason, Kojak, Barnaby Jones, Quincy, and Rockford were my preferred kid TV shows.
I also picked up on Brit TV at a very young age too. The Goodies, Reggie Perrin, Monty Python, and Fawlty Towers were probably a big influence too.
