The document discusses Chris Anderson and his concept of the "Long Tail". It describes how Anderson coined the term in 2004 to refer to the large number of unique products available in small quantities. Specifically, it notes that Anderson was the editor of Wired Magazine and later wrote a book expanding on the long tail theory. The theory holds that with a large virtual shelf space, retailers can offer more products in less demand or "niche" markets, as opposed to just focusing on popular hits. This allows businesses to profit from less popular products in addition to hits. The document provides examples of how this theory applies to industries like online music, movies, and books.
