RKO Radio Pictures was a Hollywood studio formed in 1928 by a radio company that needed customers for its sound system. Movies were turning into talking pictures, and the Radio Corporation of America (RCA) had a system for recording sound on film, called Photophone. David Sarnoff, the RCA executive behind the deal, put together a studio of its own to use it. That studio went on to release King Kong and Citizen Kane.

RKO became one of the Big Five, the five largest Hollywood studios of the era, the ones that also owned chains of theaters. It is also the only one of them that stopped making films altogether. Relay's catalog credits RKO on more than 30 films, made from 1929 to 1940. Seven of them are below.

How did a radio company end up making movies?

RKO is short for Radio-Keith-Orpheum. In October 1928 RCA took control of the Keith-Albee-Orpheum theater chain and a small studio called FBO (Film Booking Offices), and merged them. RCA now had a studio to make films with its sound system and theaters to show them in. The production arm launched in January 1929 and said it would make only all-talking films.

What happened to RKO?

After King Kong in 1933 came the Fred Astaire and Ginger Rogers dance musicals from 1934 to 1939, and Orson Welles's Citizen Kane in 1941. From 1942 Val Lewton, a producer working on small budgets, ran a horror unit that began with Cat People.

The decline began in May 1948, when Howard Hughes, the aviator and film producer, took control. In 1955 the tire maker General Tire and Rubber bought RKO through its broadcasting arm, and the old films went to television. RKO stopped making films in 1957, the year Desilu, the television company of Lucille Ball and Desi Arnaz, bought its studio lot.
