Channel 4 began broadcasting on September 14, 1958; the station has been Pittsburgh's ABC affiliate since its sign-on. From the beginning, the Hearst Corporation has been involved in the station's ownership. How the station came to be was the result of a long and complicated drama surrounding the awarding of the station's construction permit and ultimate broadcast license.
