In December 1921, RCA began regular operation of AM station WDY in Roselle Park, New Jersey,[2] although WDY was shut down just two months later, when RCA began sharing half the cost of a Westinghouse Electric and Manufacturing station, WJZ (now WABC), located in Newark, New Jersey.
WJY and WJZ shared facilities, known as "Radio Broadcast Central", which had been constructed on the sixth floor of Aeolian Hall at 29 West 42nd Street.
[4] RCA explained that it was operating two stations so that one could provide "high brow" entertainment (WJZ), and the other "popular" programming (WJY).
[6] In the summer of 1926, RCA purchased the American Telephone & Telegraph Company's (AT&T) radio operations, including its showcase New York City station, WEAF (now WFAN).
[10] In a retrospective of his time as engineer-in-charge of WJY-WJZ, Carl Dreher contrasted the prominent status WJZ held within the company's operations as compared to WJY, which he noted "never amounted to much".
