National Public Radio (NPR) is a privately and publicly funded non-profit membership media organization that serves as a national syndicator to 797 public radio stations in the United States. NPR was created in 1970, following congressional passage of the Public Broadcasting Act of 1967, signed into law by President Lyndon B. Johnson, which established the Corporation for Public Broadcasting and also led to the creation of the Public Broadcasting Service. The network was founded in 1970 with 30 employees and 90 public radio stations as charter members.
NPR produces and distributes news and cultural programming. Individual public radio stations are not required to broadcast all NPR programs that are produced. Most public radio stations broadcast a mixture of NPR programs, content from rival providers American Public Media and Public Radio International, and locally produced programs. NPR's flagships are two drive time news broadcasts, Morning Edition and the afternoon All Things Considered; both are carried by most NPR member stations, and from 2002–2008 they were the second and third most popular radio programs in the country. In a Harris poll conducted in 2005, NPR was voted the most trusted news source in the U.S.
NPR manages the Public Radio Satellite System, which distributes NPR programs and other programming from independent producers and networks such as American Public Media and Public Radio International for Sirius XM Radio.
