In 1983, 50 corporations controlled the vast majority of all news media in the U.S. ... When the 6th edition of The Media Monopoly was published in 2000, the number had fallen to six. Since then, there have been more mergers and the scope has expanded to include new media like the Internet market. More than 1 in 4 Internet users in the U.S. now log in with AOL Time-Warner, the world's largest media corporation.This might be worth remembering the next time you hear that the market will sort out any problems and there's no need for regulation. Would that there were a market so that that could be true.
In 2004, Bagdikian's revised and expanded book, The New Media Monopoly, shows that only 5 huge corporations -- Time Warner, Disney, Murdoch's News Corporation, Bertelsmann of Germany, and Viacom (formerly CBS) -- now control most of the media industry in the U.S. General Electric's NBC is a close sixth.
