Here's a short story:

National Public Radio (usually shortened to NPR, stylized as npr) is an American privately and publicly funded non-profit membership media organization that serves as a national syndicator to a network of 900 public radio stations in the United States. 

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, Public Radio International, Public Radio Exchange and WNYC Studios 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 are two of the most popular radio programs in the country. 

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. Its content is also available on-demand via the web, mobile, and podcasts. 

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 for more than 45 years. (End of story)
