A Landmark Date In Radio History

Following World War I, the newly-formed Radio Corporation of America (RCA) acquired the assets of the Marconi Wireless Telegraph Company of America, including its unfinished installations at Chatham and Marion, Massachusetts.  RCA installed state-of-the-art equipment manufactured by U.S. industrial giant General Electric, and trans-Atlantic station WSO went on the air on May 17, 1920.  Come explore our newest exhibit, “Chatham On The Air”.
