The FCC authorized stereo FM broadcasting to begin at midnight on June 1, 1961, using a multiplexing system developed by GE and Zenith. WGFM Schenectady, N.Y. (now WRVE) was the first station to broadcast regular programming in stereo at that time. WEFM Chicago (now WUSN) also began stereo broadcasting that day, but given its Central time zone location, it began an hour later.
