Radio and television are important in the world today. People can see them everywhere. Thousands of people watch TV. They even sit in front of the television every day, especially at weekends. TV is, of course, more useful than radio. On TV you can see and hear what is happening in the world. You may think that more people watch TV than listen to the radio. However, according to a recent survey（调查）, about half of the people said their radio listening hasn't changed during the past five years, and 21 percent said they are now listening more. Radio is a source of new music to 63 percent of them. Although more men than women now listen to Internet radio, that seems to change.
