Top 40 competitors

[Doug Drown]

Following up on Boom Boom Brannigan's years at WPTR when it was a Top 40
station:  I'm curious about the ratings wars that existed in metro areas
such as Albany, Hartford, Providence, Portland, Manchester, and Boston back
when each of those cities had (in most cases) two dominant Top 40 stations.
In Albany-Schenectady-Troy, for example, which station carried the top
ratings most of the time --- WPTR or WTRY?   Can anyone comment on the other
aforementioned cities, and others?
