check it out: Larry Lessig talks about the demise of freedom and the expansion of copyright law. really great presentation, and an important subject we've all probably overlooked.
(the talk is from OsCon 2002, but the info & presentation is still very topical)
interesting item you probably didn't know: when Walt Disney (the person) was first creating Walt Disney (the company), US copyright law only protected a limited set of publishing technology for a period of 14 years. these days, copyright control has been extended to a period of 70 years or more, and over a variety of everyday-use media that were previously unregulated.
