Most of the shows I watched in my life were not made for my demographic - and that's mostly be age. I'm not going to count the sci-fi/fantasy or horror shows, since they were made for a specific nerd population.
From my younger days:
In the Heat of the Night
Night Heat - some show that used to come on late nights mid-late 80s, that was basically Dragnet but they had their own reporter. I haven't seen it in decades tho
Dragnet
Columbo
Murder, She Wrote
Hart to Hart
The Love Boat
All in the Family
Benny Hill
Mr. Bean
The Honeymooners, and all of those other B&W shows that weren't family-centered.
