context: Edward John Noble, the owner of Life Savers candy, drugstore chain Rexall and New York City radio station WMCA, purchased the network for $8 million. Due to FCC ownership rules, the transaction, which was to include the purchase of three RCA stations by Noble, would require him to resell his station with the FCC's approval. The Commission authorized the transaction on October 12, 1943. Soon afterward, the Blue Network was purchased by the new company Noble founded, the American Broadcasting System. Noble subsequently acquired the rights to the "American Broadcasting Company" name from George B. Storer in 1944; its parent company adopted the corporate name American Broadcasting Companies, Inc. Woods retained his position as president and CEO of ABC until December 1949, and was subsequently promoted to vice-chairman of the board before leaving ABC altogether on June 30, 1951.
