This is an MIT Sloan Management Review article. Dozens of markets 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. Although this revolution is based on a simple set of economic and technological drivers, the authors argue that its implications are far-reaching for managers, consumers, and the economy as a whole. Looks at what has been dubbed the "Long Tail" phenomenon, examining how customers derive value from an important characteristic of Internet markets: the ability of online merchants to help consumers locate, evaluate, and purchase a far wider range of products than they can typically buy via the traditional brick-and-mortar channels. The article examines the Long Tail from both the supply side and the demand side and identifies several key drivers. On the supply side, the authors point out how e-tailers' expanded, centralized warehousing allows for more offerings, thus making it possible for them to cater to more varied tastes. On the demand side, tools such as search engines, recommender software, and sampling tools are allowing customers to find products outside of their geographic area. The authors also look toward the future to discuss second order amplified effects of Long Tail, including the growth of markets serving smaller niches.

Procter & Gamble has been in Eastern Europe for 2 1/2 years. The case outlines the problems, missed opportunities and difficulties Procter & Gamble has had in transplanting their corporate culture onto the newly liberalized economies of Eastern Europe. The case requires students to generate alternatives for Procter & Gamble's future strategy in Eastern Europe given the political, economic, societal, and technological (PEST) environment.

Procter & Gamble must determine an entry strategy for Eastern Europe. The case examines the former Soviet Bloc countries, the opportunity they provide for a business endeavor like Procter & Gamble, and the product choices Procter & Gamble has available to them. Students must examine the political, economic, societal, and technological (PEST) environment and determine if the newly liberalized economies of Eastern Europe provide appropriate investment opportunities for Procter & Gamble. Students must also determine the scope of the necessary investment, the time profile and the difficulties it may face. A follow-up case (9A97H002) is available.
