     Visitors to Britain are sometimes surprised to learn the newspapers there have such a large circulation(发行量). The Daily Mirror and the Daily Express both sell about four million copies every day. British

families generally buy a newspaper every morning and two or three on Sundays.

      Besides the national papers, there is, however, another branch of the British press which sells almost

as many copies. Local newspapers have a weekly circulation of 13 million. Almost every town and

country area has one. Nearly all of them hold their own finance(财政) and many of them are very

profitable.

      These papers are written almost entirely for readers interested in local events-births, weddings,

deaths, council(议会) meetings and sports. Editors prefer to depend on people who know the district

well. A great deal of local. news is regularly supplied by clubs and churches in the neighborhood and it

does not get out of date as quickly as national news.

     The editors must never forget that the success of any newspaper depends on advertising. They are

usually anxious to keep the good will of local businessmen for this reason. But if the newspaper is well

written and the news items have been carefully chosen to draw local readers, the businessmen are

grateful for the chance to keep their products in the public eyes.
