The decision to move the NFL's NBC telecasts to Sunday night and its ESPN telecasts to Monday night has resulted in improved ratings all around. Even though the Sunday telecasts are being beaten by some of the competition -- something that rarely occurred in the case of ABC's Monday Night Football -- NBC is drawing significantly larger audiences than MNF did a year ago. Meanwhile, ESPN is often beating the broadcast networks on Monday nights, even though nearly 20 percent of the country is still not hooked up to cable TV. It is currently averaging 12.9 million viewers each week, 36 percent more than the average for its Sunday-night telecasts during the first five weeks of the season last year.
