Fashion industry as a successful example of open source culture
The non-profit organization TED has posted on its website a video of Joanna Blackley's presentation from the recently held TEDxUSC 2010 conference at the University of Southern California. This is a very interesting lecture (15 minutes), the main idea of which is that the fashion industry with its weak use of copyright can be an example for the media industry and for the software market. It shows how the clothing design market generates hundreds of billions of dollars with virtually no intellectual property (they only have trademarks, that is, you can completely copy someone else's design, but you can not copy the logo).
Joanna Blackley is the director of the Norman Center at the University of Southern California. If you do not want to watch the video, then all the necessary information about patent reform by the fashion industry model can be found on the page of its Ready To Share research project.
As for the performance, a 12:20 video frame looks powerful, where Blackley demonstrates as an example the comparative size of markets that are poorly protected by copyright (left) and heavily protected by copyright (right).
