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"!
Interesting situation. Here in Italy we are still more on public, but sadly heading in your direction.
