 Throughout the 1960s, and very early 1970s, WKBR-FM simulcasted the top 40 format of WKBR 1250 (now WGAM), providing that station with significant extended coverage.In July 1971, WKBR-FM became WZID, and the format was flipped to beautiful music.In the 1980s, instrumental easy listening music was scaled back, with soft vocal hits added, to the point where the station evolved into an adult contemporary station.
