The first public radio network in the United States was founded in 1949 in Berkeley, California, as station KPFA, which became and remains the flagship station for a national network called Pacifica Radio. From the beginning, the network has refused corporate funding of any kind, and has relied mainly on listener support. KPFA gave away free FM radios to build a listener base and to encourage listeners to "subscribe" (support the station directly with donations). It is the world's oldest listener-supported radio network. Since the creation of the Corporation for Public Broadcasting, Pacifica has sometimes received CPB support. Pacifica runs other stations in Los Angeles, New York City, Washington, DC. and Houston, as well as repeater stations and a large network of affiliates.
