For the record, according to interviews with Gorman, Sanders and Kid Leo, WMMS had reached a crossroads by 1982, as did most AOR radio.
The choice: Go Classic Rock, or continue to break new bands and performers in a world where a) cross-polination was becoming more common (Eddie Van Halen, Paul McCartney and Mick Jagger recording with Michael Jackson, etc) and b) a whole new rock sound was emerging mainstream which included Tears For Fears, INXS, U2, OMD--most of which were breaking on Top 40, not AOR-- and c) more progressive rhythmic club oriented music was making it big (Prince, Frankie Goes To Hollywood, Duran Duran, etc).
WMMS chose to stick with emphasising, and continuing to break, current music, which was their trademark, instead of become a nostalgia station.
They (brilliantly) started reporting to Radio And Records Magazine as a "top 40 station", since (as Gorman once told me: "We played Prince before G98 did and broke him in Cleveland. But we were not allowed to report Prince as an 'add' in the trades because we were designated as an 'AOR' station, and Prince was not considered an AOR act. Neither was half the stuff we were breaking. It was ridiculous. So we changed our industry designation so we could get credit, the concerts and the giveaways. Without that, G98 would have presented all the new acts, and we would be stuck promoting Foghat".
He also told me that some AOR stations attempted to continue to play current music without the cutting edge acts, like WNEW and KMET, but that they simply played the latest Aerosmith and the latest Clapton and the latest J. Geils Band trying to make believe that they were still "current". These stations were completely destroyed within months by a fulltime classic rock on one side and a cutting edge station on the other.
WMMS was smart enough to avoid getting squeezed. They had the best ratings that they ever had from 1982 right through about 1989 with this kind of "Rock CHR" sound. They never elimninated the classics. They just very smartly weaved the hipper singles in between the standard AOR fare. Plus, they always had a bit of a rhythmic sound anyway (AWB, Isley Brothers, Hall and Oats were always big on 'MMS even in the 70s) so this was not that big a stretch.
WMMS collapsed after Kid Leo left, and a parade of PDs tried to turn the clock back with more Foreigner. The ratings died. Gorman made a smart move coming back and returning the station to breaking new music in the 90s, but then the station was sold again and new PD Bob Neumann went back to Foreigner-land, which was stupid since WNCX was doing 100% classic rock by that time.
The station was never the same since then. Dozens of PDs and consultants have tried dozens of approaches and the trademark is now
a complete mishmosh. They have not been a leader--either in breaking music or the ratings--for over ten years now, and the station completely lost a whole generation.
