YouTube is full of these TTC commercials from the '80s, and each one is better, cheesier and more fluorescent than the last. The one I've embedded is from 1985, and there are two more jingle-based ones from a couple of years later here and here. There's one with a bunch of big name celebrities like "Soap Opera Broadcaster" Vic Cummings and "Consumer Advocate" Lynne Gordon here. And in 1988, they did a whole series highlighting all the fun things you can't do on the TTC, like watch a movie or a hockey game or eat dinner. Then, in 1990, someone was clearly fired; they suddenly went in a completely different, much more poetic direction.
