The C-SPAN network includes the television channels C-SPAN, focusing on the U.S. House of Representatives; C-SPAN2, focusing on the U.S. Senate; and C-SPAN3, airing other government hearings and related programming; the radio station WCSP-FM; and a group of websites which provide streaming media and program archives. C-SPAN's television channels are available to approximately 100 million cable and satellite households within the United States. WCSP-FM is broadcast on FM radio in Washington, D.C., and is available throughout the U.S. on SiriusXM, via Internet streaming, and globally through iOS and Android apps.

The network televises U.S. political events, particularly live and "gavel-to-gavel" coverage of the U.S. Congress, as well as other major events worldwide. Coverage of political and policy events is unmoderated, providing the audience 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 associated with public policy.
