"C-SPAN, an acronym for Cable-Satellite Public Affairs Network, is an American cable television network that offers coverage of federal government proceedings and other public affairs programming via its three television channels (C-SPAN, C-SPAN2 and C-SPAN3), one radio station and a group of websites that provide streaming media and archives of C-SPAN programs. C-SPAN's television channels are available to over 100 million cable and satellite households within the United States, while WCSP-FM, also called C-SPAN Radio, is broadcast on FM radio in Washington, D.C., and is available throughout the U.S. on XM Satellite Radio, and via internet streaming. The network televises U.S. political events, particularly live and gavel to gavel coverage of the U.S. Congress as well as occasional proceedings of the Canadian and British Parliaments and major events worldwide. Its coverage of political and policy events is unedited, thereby providing viewers (or listeners) with unfiltered information about politics and government. Non-political coverage includes: historical programming, programs dedicated to non-fiction books and interview programs with noteworthy individuals connected to public policy. C-SPAN is a non-profit organization, funded by the affiliate fees paid by its cable and satellite affiliates, and does not carry advertisements on any of its networks, radio stations or websites. The network operates independently, and neither the cable industry nor Congress has power over the content of its programming."
