MHz Networks is a Northern Virginia based independent, non-commercial educational broadcaster operated by Commonwealth Public Broadcasting Corporation. The legal broadcast callsigns for the two stations of MHz Networks are WNVC (channel 24) and WNVT (channel 30). Rebranded as MHz Networks, WNVC is licensed to Fairfax, Virginia with studios in Falls Church, Virginia [1] and WNVT is licensed in Goldvein, Virginia, and shares TV studio facilities in Falls Church.

WNVT first signed on March 1, 1972 on Channel 53 as a public broadcasting independent of Public Broadcasting Service (PBS). On June 6, 1981 Channel 56 signed on as a similar station (as WIAH) and in 1982, changed its call letters to WNVC. Since channel 56 signed on, the two stations were operated from the same Northern Virginia studios, and were run as sister stations. The WNVT studios were originally at Northern Virginia Community College. When the station was under construction, the school offered an associate of arts in broadcast engineering technology. Prior to WNVT, channel 53 had a brief experimental transmission from somewhere in downtown Washington, D.C.

The Capitol Steps are an American political satire group. It has been performing since 1981, and has released approximately thirty albums consisting primarily of song parodies. Originally consisting exclusively of Congressional staffers performing around Washington, D.C., the troupe now primarily employs professional actors and singers. The Capitol Steps have performed on PBS, public radio and in various small- and medium-sized venues around the United States.

In 1981, three Republican Congressional staffers, Bill Strauss, Elaina Newport, and Jim Aidala used their spare time while working for the Senate Subcommittee on Energy, Nuclear Proliferation, and Government Processes for the Senate Committee of Governmental Affairs to sing song parodies about current events. They were joined by other Republican Senate staffers Nancy Baskin, Barbie Granzow, and Dave Nichols. Together they decided to put on a Christmas show as their first performance, while continuing to work full-time as Congressional staffers. They chose the name "The Capitol Steps" for their group based on a sex scandal earlier that year, in which then-Congressman John Jenrette had sex with his wife, Rita, on the steps of the Capitol building.
