Here's a great corporate ad from Activision circa 1981. I imagine they probably passed this off to potential clients on a nice chunky Beta tape.

We're treated to an an "in-depth" look at the creators of such classics as Ice Hockey, Kaboom! and Barnstorming as well as words of wisdom from Activision President, Jim Levy. As an added bonus we get four commercials, Freeway, Stampede, Kaboom! and Ice Hockey featuring none other than Saturday Night Live's Phil Hartman giving the performance of a lifetime. Is it just me or does he get just a little to close to that other guys face at the end?
