"When the first edition of this book was published in 1983, critics called Bagdikian's warnings about the chilling effects of corporate ownership and mass advertising on the nation's news ""alarmist."" Since then, the number of corporations controlling most of our daily newspapers, magazines, radio and television stations, books and movies has dwindled from fifty to five. Now the most respected critique of modern mass media in print has been re-published in a completely updated and revised 20th-anniversary edition."
