RKO Pictures, commonly known as simply RKO, is an American film, television and stage production company owned by Concord. In its original incarnation, as RKO Radio Pictures, Inc., it was one of the "Big Five" film studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum theater chain and Joseph P. Kennedy's Film Booking Offices of America studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RCA executive David Sarnoff engineered the merger to create a market for the company's sound-on-film technology, RCA Photophone, and in early 1929 production began under the RKO name (an initialism of Radio-Keith-Orpheum). Two years later, another Kennedy concern, the Pathé studio, was folded into the operation. By the mid-1940s, RKO was controlled by investor Floyd Odlum.
RKO has long been renowned for its cycle of musicals starring Fred Astaire and Ginger Rogers in the mid- to late 1930s. Actors Katharine Hepburn and, later, Robert Mitchum had their first major successes at the studio. Cary Grant was a mainstay for years, with credits including touchstones of the screwball comedy genre with which RKO was identified. The work of producer Val Lewton's low-budget horror unit and RKO's many ventures into the field now known as film noir have been acclaimed, largely after the fact, by film critics and historians. The studio produced two of the most famous films in motion picture history: King Kong and producer/director/star Orson Welles's Citizen Kane. RKO was also responsible for notable coproductions such as It's a Wonderful Life and Notorious, and it distributed many celebrated films by animation pioneer Walt Disney and leading independent producer Samuel Goldwyn. Though it often could not compete financially for top star and director contracts, RKO's below-the-line personnel were among the finest, including composer Max Steiner, cinematographers Nicholas Musuraca and Gregg Toland, and designer Van Nest Polglase.
