RCA

RCA Corporation, founded as the Radio Corporation of America, was a major American electronics company in existence from 1919 to 1987. Initially, RCA was a patent trust owned by a partnership of General Electric (GE), Westinghouse, AT&T Corporation and United Fruit Company. It became an independent company in 1932 after the partners agreed to divest their ownerships in settling an antitrust lawsuit by the United States.
