This is apocryphal. Anyone got any more details or remember what happened?
From Telsa Gwynne via email...
"Going further back, I remember that one of the early Linux support companies at LinuxExpo used advertising fliers of topless women photographed from behind with some punchline about "no support?" (no bra, ho ho ho) and a distribution logo to advertise the fact that they supported Linux. I think that was Linuxcare, but I am not sure. I do remember that the distribution in question (Red Hat) took exception to seeing its copyrighted logo on the back of a naked woman in order to advertise another company, and two days into the conference the Red Hat logo vanished from the fliers...
...and the Debian logo appeared, because you can do anything with that one."
From context, this would have been around 1999-2000.
