Wait what? You watched 60 Minutes everyday? It was always Sunday evenings from my memories, during winter usually right after a Football game, don’t remember the exact timing tho.
This question reminds me of the early '70s, in Italy, when only a state-owned TV channel was broadcasting, and without ads. Except between 8:30 and 9:00 pm, in a special time where the spots were like little show, the children were watching them with their eyes glued to the screen, and then... bedtime! It was "Carosello", and for the whole Italy: "the children to bed after Carosello"!
Not really a show, but Im familiar with the old CBC (canada) sign-off. Wasn't really my bed time either, I have insomnia disorder, I would just read books after the tv went off-air for the night. I'm also familiar with the CBC sign-on, and the first program on in the morning was 100 Huntley Street, followed by the PTL Club, before Jim and Tammy Faye went to jail.
we would all drop what we were doing; get together on the couch and watch it every weeknight when my parents starting enforcing a bedtime to help get them more sleep out of their working schedules.
When Cartoon Network went off and changed to Adult Swim, and this theme song started playing, you knew that it was time to go get some rest. Especially if it was on a weekend. On Sunday, it meant the fun was up, it was time to sleep and get ready for school the next day. And it was always the first show to air on the block every single night.
When I was really young (6 or 7) on weekdays it was the credits music for Dexters Laboratory, which I think ended at 8? On weekends it was The Soprano's theme. My parents would check out the season VHSs and later DVDs from the library.
NCIS, or its variants. I think where I lived, it came on at 9pm, and because my parents didn't want me to watch it, (violence and all that) it was a convenient bedtime marker.
