Newspaper is a publication that presents and comments on the news. Newspapers play an important role in shaping public opinion and informing people of current events.The first newspapers were probably handwritten news-sheets posted in public places. The earliest daily newssheet was "Acta Diurna" ("Daily Events") which started in Rome in 59 B.C. The first printed newspaper was Chinese publication called "Dibao" (pronounced "Ti -pao") started in A.D. 700's. It was printed from carved wooden blocks. The first regularly published newspaper in Europe was "Avisa Relation" or "Zeitung", started in Germany in 1609.Newspapers have certain advantages over other mass media — magazines, TV and radio.

But newspaper focuses on local news as well and provides information and comments faster than magazine can do.There are about 1700 daily and 7500 weekly newspapers in the US.

They may include special sections on such topics as entertainment, finance and travel or Sunday magazine, a guide to TV programmes, colored comics. The major dailies in the US are "Christian Science Monitor", "New York Times", "USA Today", "Wall Street Journal", "Washington Post".Weekly newspapers serve usually for smaller areas. They are printed in small communities where people know each other and are interested in activities of their friends and neighbours.
