Actually, I do remember being bombarded with the "Drink OK" campaign. Coke pasted quite a few of the TV ads in afternoon cartoon spots (back in the good old days of afternoon cartoons). The silver can with the black and white man, or was it a thumbs up? Or both. The taste was rather peculiar and no two cans seemed the same to me. I asked some of my friends recently and none of them seemed to have heard of this weird concoction. Perhaps a limited test market in urban areas?

A couple of my old friends got together back in 1995 to test the stuff and we eventually agreed that the thing tasted like a mix of coke, grape soda, and orange soda combined in random amounts for each can, though none of us were ever brave enough to actually empirically test our recipe.

To this day, I've always had the sneaking suspicion that OK was the result of some kind of soda surplus that Coke happened to have come into the possession of at that time and that rather than throwing the stuff out, they decided to sell it as a hip alternative drink. Maybe they had too much Fanta.
