RKO Radio Pictures was originally founded by RCA to promote their RCA Photophone sound system. The initials in the company name stand for "Radio Keith Orpheum", reflecting the joint venture of RCA, the Keith Orpheum theater circuit, and the Film Booking Office of Joseph P. Kennedy, the father of the 35th U.S. President, John F. Kennedy. It was one of the Big Five studios of Hollywood's Golden Age (the other were MGM, Paramount Pictures, Warner Bros. Pictures and 20th Century Fox). Howard Hughes would purchase the studio in 1948 and sell off the studio to the General Tire and Rubber Company in 1955. In 1981, RKO would reenter film production through a new subsidiary, RKO Pictures. The rights to the majority of the in-house RKO Radio Pictures films are owned by the current RKO Pictures with distribution rights owned and/or licensed to Warner Bros. Pictures via Turner Entertainment Co., while Walt Disney Pictures owns the rights to their own productions and films produced by Selznick International Pictures (the latter via ABC Motion Pictures, except Gone with the Wind), the Samuel Goldwyn, Jr. family trust owns the rights to Samuel Goldwyn Productions films, Paramount Pictures owns It's a Wonderful Life via Republic Pictures, and Universal Studios owns films produced by Hughes.
