Television can gives us advantages and disadvantages, increase our knowledge of the outside world science medicine, the arts, and so on. Moreover,there are several serious disadvantages to television.That its influence is often negative.Many children stare at a TV screen for more hours each day than they do anything else, including studying and sleeping.Recent studies show that after only thirty seconds of TV, a person's brain “relaxes” the same way it does just after the person falls asleep.Children who view a lot of TV can often concentrate on a subject for only fifteen to twenty minutes; they can pay attention only for the amount of time between commercials!
Another disadvantage is that TV often causes people to become dissatisfied with their own lives. Real life does not seem as exciting to these people as the lives of actors on the screen. On the screen, actors solve serious problems in a half- hour program or a thirty-second commercial.
