Billboard companies consolidating
In the mid-1950s, ABC merged with United Paramount Theatres, a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures.
Leonard Goldenson, who had been the head of UPT, made the new television network profitable by helping develop and greenlight many successful series.
In addition, to comply with FCC ownership restrictions, it would have been required to sell either WABC-TV or Du Mont owned-and-operated station WABD in the New York City market, as well as two other stations.
In doing this, he contacted local entrepreneurs who owned television stations themselves, many of whom had previously invested in Paramount cinemas and had worked with him when he undertook the responsibility of restructuring United Paramount Theatres.
Goldenson added to the confusion when, in October 1954, As part of this merger, the network would have been renamed "ABC-Du Mont" for five years, and Du Mont would have received million in cash, room on the schedule for existing Du Mont programming, and guaranteed advertising time for Du Mont Laboratories receivers.At the same time he made attempts to help grow ABC, Goldenson had been trying since mid-1953 to provide content for the network by contacting his old acquaintances in Hollywood, with whom he had worked when UPT was a subsidiary of Paramount Pictures.the latter of which had previously been more connected to radio.To comply with FCC ownership restrictions in effect at the time that barred common ownership of two television stations in the same market, UPT sold its Chicago television station, WBKB-TV, to CBS (which subsequently changed the station's call letters to WBBM-TV) for million, The WABC call letters were previously used by the flagship station of CBS Radio (now WCBS (AM)) until 1946.
The WJZ calls would later be reassigned to the then-ABC affiliate in Baltimore in 1959, in an historical nod to the fact that WJZ was originally established by the Baltimore station's owner at the time, Westinghouse.The television network has eight owned-and-operated and over 232 affiliated television stations throughout the United States and its territories.
