Sponsored by TED, Larry Lessig, the Stanford Law Professor, speaks on a twist on Copyright Law.I highly recommend watching the video for a very enlightening interpretation and the requirements for Copyright Law.  It talk alot about speech, copyright violations, use, and ownership.  He frames the issue very much as in the artists control.  That artists are the ones that are required to license their music or their creations for public consumption and use.  You can find the video here.
