Read about the "Theory of the Long Tail" and the new marketplace here.
"The Long Tail article (and the forthcoming book) is about the big-picture consequence of this: how our economy and culture is shifting from mass markets to million of niches. It chronicles the effect of the technologies that have made it easier for consumers to find and buy niche products, thanks to the "infinite shelf-space effect"--the new distribution mechanisms, from digital downloading to peer-to-peer markets, that break through the bottlenecks of broadcast and traditional bricks and mortar retail."
If you go to Chris Anderson's blog (link above) there is an interesting article on the "new" Al Gore.
