"In 1983, 50 corporations controlled the vast majority of all news media in the U.S.
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."
This was a good 3-4 years ago. Things haven't gotten better since then.
