From Niches to Riches: Anatomy of the Long Tail

The Internet marketplace allows companies to produce and sell a far wider range of products than ever before. This profoundly changes both consumer behavior and business strategy.

Eric Clemons, a professor at the Wharton School, is an aficionado of Dogfish Head World Wide Imperial Stout beer at $160 per case. How did Dogfish Head find a customer like him? They didn’t. He found them. Clemons was not always a connoisseur of rare beers, but after trying Victory Hop Devil beer, the top-ranked India pale ale at the time, he learned of Dogfish Head, as well as Victory’s Storm King Imperial Stout and other niche beers, through the Internet. Clemons notes that he “would never have bought the Dogfish Head without the reviews on and without the chain of experiences with ever-more interesting beers along the way.”

For most of the past century, companies of all types strove to introduce products and services that were blockbuster hits and could capture the mass market. Bigger was better. But now dozens of markets, from beer to books, music to movies, and software to services of all types are in the early stages of a revolution as the Internet and related technologies vastly expand the variety of products that can be produced, promoted and purchased. Though based on a simple set of economic and technological drivers, the implications of this are far-reaching for managers, consumers and the economy as a whole.

Early discussions of Internet markets focused on how “frictionless commerce” would lead to fierce price competition online. However, while consumers certainly do benefit from lower prices online, our research indicates that they derive far more value from another important characteristic of Internet markets: the ability of online merchants to help consumers locate, evaluate and purchase a far wider variety of products than they can via traditional brick-and-mortar channels.1 (See “About the Research.”)

About the Research »



1. In contrast to early predictions of commoditization and pure price competition, academic studies have found that price dispersion is often higher online than in brick-and-mortar stores (see E. Brynjolfsson and M.D. Smith, “Frictionless Commerce? A Comparison of Internet and Conventional Retailers,” Management Science 46, no. 4 [April 2000]: 563–585), and have highlighted the importance of search (Y. Bakos, “The Emerging Role of Electronic Marketplaces on the Internet,” Communications of the ACM 41, no. 8 [1998]: 35–42) and brand and loyalty in Internet markets (M.D. Smith and E. Brynjolfsson, “Customer Decision-making at an Internet Shopbot: Brand Still Matters,” Journal of Industrial Economics 49, no. 4 [2001]: 541–558).
