National Public Radio (NPR) is a semi-independent, privately and publicly funded non-profit membership media organization that serves as a national syndicator to 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 Johnson, which established the Corporation for Public Broadcasting and also led to the creation of the Public Broadcasting Service.

Its two flagship programs on weekdays are Morning Edition and its afternoon equivalent, All Things Considered, both of which have had Muppets as guests. Gary E. Knell and Rosita are scheduled to appear on Tell Me More, Thursday, May 15, 2008.
