There is no doubt that watching television and can influence the way that people behave. Moreover, it seems that people are spending more and more time watching some sort of visual entertainment, whether it is television, a video tape or a DVD. Therefore, the effects of visual media cannot be ignored.

One obvious effect of the these media is that watching them induces people to buy certain products. television advertising is widespread and, nowadays, even movie theaters permit advertisements. Another way TV and the movies affect people is that they give people either a broader view of the world or a distorted（扭曲的） one, depending on what type of program they watch. Those who watch news and educational program can learn many new things while those who watch primarily entertainment shows may come to believe that most people in the world possess great wealth and good looks. It may make them become dissatisfied with their own lives.
