For my age I think Gilligan's Island, Brady Brunch then Wekcom Back Kotter or Starsky and Hutch are fairly iconic. when rememberingmy years. College years it became Hill St Blues. After that, I don't recall any that I associate with a period of life. Rental movies then streaming became a thing and sitting around tv's at a regulated time, less part of the regular schedule, Maybe that's why I can't think of any songs past the early 80? A lot of the shows people talk about, I only watched after they had completed their run or binged to catch up. "Skip opening sequence" is one of my favorite parts of a show.
