General Electric (GE) formed the Radio Corporation of America (RCA) as an operating company for the purpose of providing radio communication equipment and service. RCA functioned as the exclusive distributing agent for communications apparatus made for it by
GE, Westinghouse and The Wireless Specialties Apparatus Company.  RCA also distributed vacuum tubes manufactured by these companies. RCA was formed by GE on October 17, 1919. On November 20, 1919, the American Marconi Company was merged into RCA.
A cross-licensing agreement was affected between RCA and GE. On July 1, 1920, a cross-licensing agreement was signed between GE and AT&T. By another agreement on the same date, the rights to the patents outlined in the cross-licensing agreement were extended to RCA and the Western Electric Company. A similar cross-licensing agreement between RCA and the Westinghouse Electric and Manufacturing Company was signed June 30, 1921. Through these patent licensing and manufacturing arrangements RCA controlled most of
the technology for providing broadcast radio receiving equipment.
