问题  
Americans get some of their news and entertainment from public television and radio. These public media receive money to operate from private citizens, organizations and government. Many of their programs are educational.
    But most of the American media are run by businesses for profit. These privately owned media have changed greatly in recent years. Newspapers, magazines and traditional broadcast television organizations have lost some of their popularity. At the same time, online, cable and satellite media have increased in numbers and strength.
    In general, more media than ever now provide Americans with news and entertainment. At the same time, fewer owners control them. Huge companies have many holdings. In some areas, one company controls much of the media.
    One dramatic change in American media is the increased success of cable television. It comes into most homes over wires. It does not use the public airwaves, as broadcast television does. Like broadcast television , most cable television programs include sales messages. This is true although people must pay to see cable television in their homes.
    Thirty years ago, few people had cable. Today, about 68 percent of American homes have cable television. Television by satellite also is gaining popularity. Over the years, traditional broadcast organizations have tried to appeal to as many watchers as possible.
