On September 1, 1957, Pittsburgh's second commercial VHF station signed on as WIIC. The station's construction permit was originally issued by the Federal Communications Commission (FCC) in June 1955 to WIIC Incorporated – a joint venture of the Pittsburgh Post-Gazette, which owned WWSW radio (970 AM, now WBGG), and Pittsburgh Radio Supply House, the then-owners of WJAS radio (1320 AM). Both radio stations had competed individually for the permit grant along with other applicants. CBS, which was looking to gain its own full-time affiliate in the market, signed a contract with the then-unnamed channel 11 shortly thereafter. Before the "freeze" on television station licenses, the two stations were competing for the channel 10 license originally assigned to Pittsburgh before the FCC reallocated the channels in 1952, with channel 10 going to Altoona; the Hearst Corporation (then-owners of WCAE and eventual owners of WTAE-TV) and two other companies were also applying for the channel 10 license.
