Nevertheless, there are several serious disadvantages to the visual media. First of all, some people watch the “tube” for some hours in a day than they do anything else. In a large number of homes, TV sets-as many as five or more in a single household-are always one. Many people watch TV for many hours a day or spend hours playing games or surfing on their computers; they download music, movies and other forms of entertainment. Instead of spending time taking care of their kids, parents often use a video screen as an “electronic baby-sitter.” As a result, television and video can easily replace family communication as well as physical activity and other interests.
