Today, the only way for media companies to survive is to own everything up and down the media chain -- from broadcast and cable networks to the sitcoms, movies, and news broadcasts you see on those stations; to the production studios that make them; to the cable, satellite, and broadcast systems that bring the programs to your television set; to the Web sites you visit to read about those programs; to the way you log on to the Internet to view those pages. Big media today wants to own the faucet, pipeline, water, and the reservoir.
