Today there is a television set in almost every house. In some countries, you can  choose between as many as forty different channels; some show only a single type of program - news, sports, music, theater or movies; most show different kinds of programs, giving the viewer a lot of choices to choose from. In one country, a recent research showed that the average person spent three and a half hours a day watching television. Housewives were the biggest group of viewers. They spent an average of about five hours a day watching TV while their husbands were out at work.
