A newspaper, published usually on a daily or weekly basis, has the main function of reporting news. Many newspapers also furnish their readers with other pieces of useful information, such as weather reports, TV program broadcast, and other kinds of information. They provide commentary on politics, economics, arts and culture. In nearly all cases and in different degrees, newspapers depend on commercial advertising for their income.

A survey said that nearly six out of ten adults in the United States and Canada read a newspaper every day, and seven out of ten read a paper each weekend. By the time they see a newspaper, most people have already heard about breaking news stories on TV or on the radio. Readers depend on newspapers to provide detailed information and analysis (分析) which TV and radio almost don’t offer. Newspapers not only tell readers that an event has happened but also help readers understand what led to the event and how it will affect the world.

The members of a large newspaper work under the nonstop pressure of deadlines to bring news to readers as quickly as their minds, bodies and the technology they use permit. Reporters, photographers, artists, and editors find the materials and form articles and graphics (图片) —sometimes in just a few hours. Page designers combine articles, photos, advertisements, and eye-catching headlines into page layouts (版面), then quickly print the paper out. Printing system may work through the night to print out more than 60,000 copies per hour.
