I cannot even imagine a time when an ad like this would be necessary. To actually have to tell people to drink coffee. Well, perhaps before Starbucks covered the earth. Then, maybe ;)

Video info from the contributor, brengibble:

Digitized from a 1984 VHS tape. This is one of the famous Coffee Achievers tv spots, meant to encourage people to DRINK COFFEE. You can see how we here in the 21st Century have to laugh ourselves senseless at the idea that paid ads were necessary, and not even for a particular brand of coffee, just the product in general. Appearing in this ad: David Bowie (Jay Leno in 1985: “Come on! To David Bowie, a cup of coffee is merely a sedative at this point.”), Kenny Anderson, Kurt Vonnegut, Ann Wilson and Nancy Wilson of the band Heart, and Cicely Tyson.
