" In 2004 Chris Anderson wrote an influential book called The Long Tail. In it, he argued that the future of business is to sell less of more.

This is because there is a large number of people who belong to the long tail and they encompass a wide rage of tastes.

A classic example of successful long tail sales is Amazon. A substantial subset of the book sales for the largest online retailer comes from obscure books. Amazon itself could afford to stock up on rare books as well as offer these via numerous online partners. The net effect is that a lot of book sales occured in the long tail. This phenomenon is captured nicely in a quote from an Amazon employee: "We sold more books today that didn't sell at all yesterday than we sold today of all the books that did sell yesterday.""
