Ad Blast from the Past

Whatever: Asimov and the Cleti
John Scalzi has a blog entry with a picture of an old ad from the early 1980’s where Issac Asimov shills for a TRS-80.
It reminds me of a television commercial I recall from the same era, where Arthur C. Clarke was shilling for a new and exciting science/science fiction magazine called Omni.
As I recall, the production values for the commercial were pretty low, just like the ad that John has put up. And of course, Omni is long gone and I don’t foresee Greg Bear doing a TV commercial anytime soon.
