With the rapid development of economy and advancement of technology, television has become an indispensable part of the mass culture. As one of the most important inventions in the 20th century, it has an immeasurable influence on human beings, especially children. Compared to the other kinds of media, television is characterized by integrating images with sound. In this way, the visual impact provided by television satisfies children's pursuit of entertainment. However, some researchers found that TV watching time was negatively associated with the diet and physical activity (Taras, Sallis, Patterson, Nader & Nelson, 1989). The disadvantages of TV have terribly affected children. This essay will firstly discuss the advantages of TV watching for children from three aspects. Following this, it will demonstrate the disadvantages of watching TV. Finally, it will make a comment on the opinion that the advantages of TV outweigh the disadvantages for children.On the one hand, in accordance with some medical studies, children benefit a lot from watching TV. First of all, children's curiosity of knowing more about the surrounding around them is raised by watching TV since the visual and the sound effect are well combined in the advertisement.

By constantly absorbing large amount of information, the ability of assessment and analysis will also be improved.On the other hand, the disadvantages of TV watching have an affect on the growth of children.
