In contrast, by 1953 ABC had a full complement of five O&Os, augmented by nine primary affiliates. ABC also had a radio network (it was descended from NBC's Blue Network) from which to draw talent, affiliate loyalty, and generate income to subsidize television operations. However, ABC had only 14 primary stations, while CBS and NBC had over 40 each. By 1951, ABC was badly overextended and on the verge of bankruptcy. That year, the company announced a merger with United Paramount Theaters (UPT) (the former theater division of Paramount Pictures, which was spun off as a result of the "United States v. Paramount Pictures, Inc." antitrust decision), but it was not until 1953 that the FCC approved the merger.
