       Reader's Digest is a monthly magazine. Before the 1980s, it belonged to a privately held company, which

was started in 1922 by Lila Bell Wallace and Dewitt Wallace. This magazine is small and easy to carry, just half

the size of most American magazines, which caused a phrase in 2005, "America in your pocket." It is the best

selling magazine in the USA. At present, its circulation (发行量) in the USA has reached 10 million copies and

the number of the readers there is 38 million. Its global circulation outside the USA has reached 40 million people

throughout more than 70 countries in 21 languages.

       This magazines focus (焦点) is not news but more of cultural views because the editors think people now

can get timely news from somewhere else. They hope this magazine can give readers something that is about

special personal experiences, something the readers can share with their families. In different countries, this

magazine provides a window to the world for the local readers. Some parts of the magazine are about the local

customs and interests of the local readers. The other parts give the local readers information from all over the

world.

       This magazine actually used to be a family business until the Wallaces died in the 1980s. Because they had

no children, there was no one to take over the company. Sixteen years ago, this company went public and

became a public company.
