A national public radio network, National Public Radio (NPR), was created in February 1970, following the passage of the Public Broadcasting Act of 1967. This network replaced the Ford Foundation-backed National Educational Radio Network. Some independent local public radio stations buy their programming from distributors such as NPR; Public Radio International (PRI); American Public Media (APM); Public Radio Exchange (PRX); and Pacifica Radio, most often distributed through the Public Radio Satellite System. Cultural Native American and Mexican American music and programming are also featured regionally. NPR is colloquially though inaccurately conflated with "public radio" as a whole, when in fact "public radio" includes many organizations.
