The large number of mergers in information industries raises the question of whether the information sector as a whole, and which of its constituent industries, has become more concentrated and by how much. This chapter examines these issues and investigates horizontal concentration on a national level. To determine whether horizontal concentration has increased, Herfindahl-Hirschmann Index figures for specific industries and sectors are analyzed. The industries of electronic mass media distribution encompass radio stations, television stations, direct broadcasting satellites, and cable television. As can be seen in the chapter, all industries involved have increased in concentration after 1996, and basically have increased in concentration since 1984. This chapter also analyzes ownership concentration trends in the film industry, music industry, print and publishing, consumer electronics industry, computer and software industry, telecommunications industry, information technology, and Internet sector.

Keywords:   horizontal concentration, ownership, Herfindahl-Hirschmann Index, electronic mass media, radio stations, television stations, film industry, telecommunications industry, Internet, information technology
