From time to time some interesting Linux commercials pop up on the Internet. Here's a few of them.
A personal remix video someone did just for fun
One of the best Red Hat commercials
The well known "Prodigy" IBM commercial
The vintage-style IBM servers running Linux movie
And finally a Novel spoof of MAC commercials with debatable outcome
The funniest comment I read about this one: a tyler-from-fight-club style jacket straight outta 1999. Not exactly "keeping up with the latest trends".
