There is no doubt that watching television and movies 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 the visual media cannot be ignored.

One obvious effect of these media is that watching them induces(诱导)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 programs can learn many new things while those who watch primarily entertainment shows may come to believe that most people in the world have great wealth and good looks. It may make them become dissatisfied with their own lives. Finally perhaps the most susceptible(易受影响的)viewers are children, who may be unable to tell fact from fiction and may try to copy acts that they see on TV or in the movies.

With the ever-increasing popularity of video entertainment, society must pay attention to these effects. Television and movies, while entertaining and informative, cannot take the place of real experiences.
