WBZ-FM went through various format tweaks during the 10 years of its existence. In 1972 it was an automated but really good Top 40 station playing a decent mix of album cuts and oldies too. In early 1973,
the format nose dived ! "The Station That Has Teenagers Talking" was just god awful!!! The Boston Top 40
counted down daily with teenagers introducing every song and reading most of the PSAs. The station would not play anything that wasn't in the current Top 40, in fact. Later in the year, Clark introduced "The Music Show" which was late night AOR from around midnight to 2AM sign off. By late 1973, the daytime format became modified again, with Captain Ken counting down the Boston Top 40 and oldies and album cuts going back into the regular rotation. In 1974 and 1975, they had a pretty good early evening artist spotlight feature, and "The Music Show" moved up to about 9PM. In 1975, Clark and Captain Ken exited the station, (soon to start up WCOZ) and it became kind of a Top 40 jukebox for awhile. By 1978, it was drifting towards AOR. In 1979, they were definitely automated AOR" frequently IDing as "New Wave Stereo-106.7" and Z-107. In 1980 and through its final days in 1981, it continued as AOR, IDing as Z-107. The Top 40 charts that they put out in 1975 and 1976 definitely resembled WRKO, but the survey that I have from them from late 1978 is definitely the playlist of an AOR station which that survey refers to as Z-107.
WBZ-FM lasted for exactly ten years as a contemporary music station too...flipping from Classical on 12/30/71 and going dark temporarily, I seem to remember starting right around 1/1/82. Of course, "Magic 106.7-WMJX" appeared in January, 1982. The WMJX call letters actually took effect during the summer of 1981, while the station was still AOR. During the summer and Fall of 1981, they simply identified it as "FM-107"....
