Professor Jerold M. Starr looks at corporate control of the U.S. media and calls for a new independent public broadcasting system: "Today a mere six corporations control more than half of all communications enterprises: books, magazines, newspapers, music, motion pictures, radio and television. Some 77 percent of the nation's daily newspapers are part of chains. Two firms control more than half the market for 11,000 magazines. Four firms control our broadcast TV networks and almost all the cable networks. Twenty-five radio groups control one-fourth of the stations and 57 percent of the revenue." And PBS is no meaningful alternative.
