Gulf + Western, founded in 1958 by Charles Bluhdorn, became one of the most highly diversified conglomerates in the United States. Gulf + Western took control of the Paramount Pictures Corporation in 1966. Gulf + Western changed its name to Paramount Communications Inc. in 1989 and was acquired by the media conglomerate Viacom Inc. in 1994.
