I always loved these expensive promos that networks used to do to "sell" you on their new fall season. The idea always seemed to be to embed the notion — which I doubt any sentient human being ever bought — that there was something so wonderful and hip and crowd-pleasing about their schedule that you should just leave your dial tuned to their station all year. I'm sorry they so rarely make these spots these days. You always got a catchy jingle — to the point where many of them would reverberate in your skull, long after the shows they were trying to sell had been cancelled. And as in this one, you often got the spectacle of the season's stars participating, smiling like they really want to be a part of it all. Here's what ABC did in 1978 along those lines.
