It's prolly been close to 35 years since I've seen this commercial, but why not.
Somewhere between 1988-90 - give or take a year - there was a long-distance commercial where a woman talks about being on a game show. The game show wasn't really a significant part of the ad, and I think her "consolation prize" was free long-distance service. I swear it was an AT&T ad but it might've been MCI. The only other thing I remember is that the "game show" portion was either black and white or a really dull blue tone (think CSI: NY). Me being a huge game show fan at the time, I was obsessed with the commercial.
Does this ring a bell for anyone? I looked through Youtube commercial compilations, to no avail.
