As the only television station that was built from the ground up by the Westinghouse Electric Corporation, WBZ-TV began operations on June 9, 1948, at 6:15 p.m. with a news broadcast hosted by Arch MacDonald. The station was from its inception associated with the NBC television network, owing to WBZ radio (1030 AM)'s longtime affiliation with the NBC Red Network. At its sign-on, WBZ-TV became the first commercial television station to begin operations in the New England region. The station originally operated from inside the Hotel Bradford alongside its radio sister; its current home was not completed at the time, although master control and its self-supporting tower over the building were in use at sign-on. The WBZ stations would not move into what was then known as the Westinghouse Broadcasting Center until June 17, 1948, when the building was opened.
