This was a really interesting video which I found on a Science, Culture and Knowledge blog. I think the guy speaking in this video is right in many ways as he describes how he thinks social media is potentially going to change the way the whole world does business.
You can see how his ideas could be applied with respect to data and electronic information (including music and video). Although I am not sure how it relates to physical products, other than perhaps sharing manufacturing information. But you can see how sharing and providing information or services for free has huge potential, particularly from an advertising perspective or by then offering further services that could potentially be offered at a price.
