Like the press in most other countries, American newspapers range from the “sensati onal”, which feature crime, sex and rumor, to the serious, which focus on factual news and the analysis of world events.But with few exceptions American newspapers try to entertain as well as give information, for they have to compete with television.
Just as American newspapers give way to all tastes, so do they also try and apply to readers for all political persuasions.A few newspapers support extremist (过激分子)groups on the far right and on the far left, but most daily newspapers attempt to attract middle-of-the-road Americans who are essentially moderate.Many of these papers print columns by well-known journalists of different political and social views in order to present a balanced picture.
As in other democratic countries American newspapers ca n be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once bravely uncovered political scandals (丑闻)or crimes, for instance, the Watergate Affair.The newspapers dr ew the attention of the public to the fears of the Vietnam War.
