?create like it?s 1790!?
A while ago, a friend sent me a link to a Flash presentation of a speech by Stanford Law School professor Lawrence Lessig on free culture, given at Oscon 2002 but the issues are still very current. In his beautiful and moving half hour speech, Lessig touches on the history and evolution of copyright law, Mickey Mouse, the brothers Grimm and The Simpsons, the increasing control of a few over common culture, DRM and the Broadcast Flag, software patents, free software and the EFF.
If you want to watch only one presentation on copyleft issues, this one would be a good choice.
