Saved By The Bell was a Saturday Morning program. Actually the first season was called Good Morning Miss Bliss. It aired on NBC, and rang the death knell for Saturday Morning cartoons. Yes, I watched it. I was in my mid 20's.
You bring up an interesting point. I used to get up way early on Saturday mornings, and watch shows like The Bugs Bunny/Roadrunner hour. Now I can get up at about that same time, and see local news. When did that change? Children's programming (cartoons or otherwise) now does not start until 9:00 a.m.
