I" d like to propose that for sixty to ninety minutes every evening fight after the early evening news, all television broadcasting in America be prohibited by law.
Let us take a serious, reasonable look at what the results might be if such a proposal were accepted. Families might use the time for a real family hour. Without the distraction of TV, they might sit around together after dinner and actually communicate with one another. It is well known that many of our problems -- everything, in fact, from the generation gap to the high divorce rate to some forms of mental illness -- are caused at least in part by failure to communicate. We do not tell each other what makes us feel disturbed. The result is emotional difficulty of one kind or another. By using the quiet family hour to discuss our problems, we might get to know each other better, and to like each other better.
On evenings when such talk is unnecessary, families could rediscover more active pastimes.Freed from TV, forced to find their own activities, they might take a ride together to watch the sunset, or they might take a walk together (remember feet？) and see the neighborhood with fresh new eyes.
With free time and no TV, children and adults might rediscover reading. There is more entertainment in a good book than in a month of typical TV programming. Educators report that the generation growing up with television can barely write an English sentence, even at the college level. Writing is often learned from reading. A more literate new generation could be a product of the quiet hour.
A different form. of reading might also be done, as it was in the past: reading aloud. Few hobbies bring a family closer together than gathering around and listening to mother or father read a good story. The quiet hour could become the story hour. When the quiet hour ends, the TV networks form. our newly discovered activities.
At first glance, the idea of an hour without TV seems radical. What will parents do without the electronic baby-sitter？ How will we spend the time？ But it is not radical at all. It has been only twenty-five years since television came to control American free time. The people who are thirty five and older can remember childhood without television, spent partly with radio -- which at least involved the listener" s imagination -- but also with reading, learning, talking, playing games, in venting new activities. It wasn" t that difficult. Honest. The truth is that we had a ball.
