High Quality Content by WIKIPEDIA articles! RKO (Radio-Keith-Orpheum) Pictures is an American film production and distribution company. As Radio Pictures Inc. and then RKO Radio Pictures Inc., it was one of the so-called Big Five studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum (KAO) theater chains and Joseph P. Kennedy's Film Booking Offices of America (FBO) studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RCA chief David Sarnoff engineered the merger in order to create a market for the company's sound-on-film technology, RCA Photophone. By the mid-1940s, the studio was under the control of investor Floyd Odlum.
