The Long Tail

The Long Tail was a theory made in 2006 by CHRIS ANDERSON.
To some it up the theory can be boiled down to :
Our culture and economy are increasingly shifting away from focus on a relatively small number of hits (mainstream products and markets) at the head of the demand curve,and moving toward a huge number of niches in the tail. In an era without the constraints of physical shelf space and other bottlenecks of distribution,narrowly targeted goods and services can be as economically attractive as mainstream fare.The Long Tail is a retailing concept describing the niche strategy of selling a large number of unique items in relatively small quantities – usually in addition to selling fewer popular items in large quantities.
