Who bought RKO Studios in the 50's?

Desilu Productions was an American television production company co-owned by husband and wife Desi Arnaz and Lucille Ball, best known for shows such as I Love Lucy, Star Trek, and The Untouchables. Until 1962, Desilu was the 2nd largest independent television production company in the U.S. behind MCA's Revue Productions until MCA bought Universal Pictures, and Desilu became and remained the #1 independent production company until being sold in 1967. Ball and Arnaz jointly owned the majority stake in Desilu from its inception until 1962, when Ball bought Arnaz out and ran the company by herself for several years. She eventually sold the company in 1967 to Gulf+Western; after the sale, company officials renamed it Paramount Television.
