Media Ownership and Concentration in America

Oxford University Press

Although the three major subsectors of the information sector—mass media, telecommunications, and information technology—developed at different times and paces, technological and regulatory tendencies affected them in roughly the same periods. In the 1990s, a fourth subsector emerged—Internet media. This chapter asks: Has it been subject to similar dynamics of market structure? Is the Internet still as open and competitive as it used to be, or is it becoming concentrated and dominated by a few firms with market power? This chapter looks at the market concentration trends for eight Internet sector industries in the United States: Internet backbones, Internet service providers, broadband providers, search engines, browser software, portals, Internet protocol telephony, and media player software. The revenue and market share of each firm for a period of up to twenty years are also calculated. These market shares are then used to calculate concentration indices and track them over time.

Keywords:   United States, market concentration, Internet, search engines, revenue, market share, Internet service providers, portals, market structure
