C-SPAN is a private, non-profit public service of the cable television industry. Even though the network’s programming covers the political process, it receives no funding from any government. C-SPAN earns its operating revenues through license fees paid by cable systems that offer the network to their customers.
The cable television industry created C-SPAN (Cable-Satellite Public Affairs Network) in 1979 to provide live, gavel-to-gavel coverage of the U.S. House of Representatives. Since those early days, C-SPAN has grown into a diverse information service that provides public affairs programming 24 hours a day in a variety of formats. Today the cable industry remains the primary distributor of the C-SPAN networks and continues that distribution as a service to the public.
C-SPAN is a non-profit educational organization with a board of directors comprised of executives from large and small cable television operating companies. While the board establishes network policy and provides financial oversight, it is not involved in C-SPAN’s editorial decision-making.
