Television's landscape 40 years was a big push for eyeballs. When only a few networks were in existence, each of the national broadcasters were in fierce competition for viewers. In 1980, it seems ABC decided to go all in. One single promo that lasts a whopping minute and forty seconds features every. single. actor. on its network.
How ABC was able to get the talent for each program onto a set at a single time is beyond my comprehension but it's a feat ABC achieved. Crazy to think that not only were these big A-List actors but they were all likely compensated for their time do to this promo. Complete with original music, lyrics, and basically a dance number, this promo leaves nothing on the table.
If ABC was going to go this hard, this "You and Me" promo is certainly money well spent.
