National Public Radio (NPR, stylized in all lowercase) is an American nonprofit media organization headquartered in Washington, D.C., with its NPR West headquarters in Culver City, California. It serves as a national syndicator to a network of over 1,000 public radio stations in the United States. It differs from other non-profit membership media organizations such as the Associated Press, in that it was established by an act of Congress. Funding for NPR comes from dues and fees paid by member stations, underwriting from corporate sponsors and annual grants from the publicly-funded Corporation for Public Broadcasting. Most of its member stations are owned by non-profit organizations, including public school districts, colleges, and universities. NPR produces and distributes both news and cultural programming. The organization's flagship shows are two drive-time news broadcasts: Morning Edition and the afternoon All Things Considered, both carried by most NPR member stations, and among the most popular radio programs in the country. the drive-time programs attract an audience of 14.9 million and 14.7 million per week, respectively. NPR manages the Public Radio Satellite System, which distributes its programs and other programming from independent producers and networks such as American Public Media and Public Radio Exchange, and which also acts as a primary entry point for the Emergency Alert System. Its content is also available on-demand online, on mobile networks, and in many cases, as podcasts. Several NPR stations also carry programs from British public broadcaster BBC World Service. Name The organization's legal name is National Public Radio and its trademarked brand is NPR; it is known by both names. In June 2010, the organization announced that it was "making a conscious effort to consistently refer to ourselves as NPR on-air and online" because NPR is the common name for the organization and the tag line "This ... is NPR" has been used by its radio hosts for many years. However, National Public Radio remains the legal name of the group, as it has been since 1970. History 1970s National Public Radio replaced the National Educational Radio Network on February 26, 1970, following Congressional passage of the Public Broadcasting Act of 1967. This act was signed into law by 36th President Lyndon B. Johnson, and established the Corporation for Public Broadcasting, which also created the Public Broadcasting Service (PBS) for television in addition to NPR.
