The Long Tail

The Long Tail theory suggests that our culture and economy is increasingly shifting away from a focus on a relatively small percentage of "hits" (mainstream shotgun approach for most products and markets) at the head of the demand curve and toward a huge number of niches in the tail.

Why the shift? As the costs of production and distribution continues to fall – new technology, Internet, etc. – there is now less need to lump products and consumers into "one-size-fits-all" bundles.

In an era without the physical constraints of shelf space and other distribution bottlenecks, niche goods and services are becoming economically attractive. Chris Anderson, editor-in-chief of Wired Magazine, wrote The Long Tail. It first appeared in Wired in October 2004.
