An oligopoly (from the Greek, "few sellers") is a market that is dominated by a few large and powerful players. As the author documents with numerous examples, virtually every industry today - from medical equipment to airlines, toy retailing to oil - is moving in this direction, in the greatest movement toward industry consolidation and concentration since the turn of the 20th century. Everyone who reads the newspapers is aware of the dizzying pace of mergers, acquisitions, buyouts, and alliances, between big companies and small companies in every industry. Such deals, along with the growing social and political clout of the biggest companies, are critical issues for the economy and for our future as consumers. Charting the course of this trend around the world, the author examines the motivations behind consolidation into corporate empires, how companies exert political pressure to their advantage, and how the actions of the most dominant players, such as Coca-Cola, Wal-Mart, Viacom, Dell, ExxonMobil, Citigroup, and others, affect the choices we have at the supermarket, the drugs we are prescribed, and the movies we watch. Considering the implications of industry concentration on competition, technological innovation, business management, strategy, consumer behaviour, and politics, this book paints a provocative, but balanced, picture of big business and its impact on society.
