According to a recent Nielsen survey of television viewing habits, women over 55 average almost 36 hours in front of the tube each week. Children under 6 watch 27 hours in the same period. In the average American household, the television is on for 6 hours and 44 minutes a day. One media journalist suggested that if someone from another planet wanted to beam a message to earth and reach the largest possible audience, he should interrupt a situation comedy on Sunday night in November between 8:30 and 9 o'clock. At that time nearly 100 percent of the households that own a TV have their set in operation. Just think, during some evenings the residences of almost any street in the United States have one thing in common - a bluish-white glow flickering in the windows!
