Long time ago in a mythical galaxy called 'Bethesda', there originated a form of intelligence that punctually (and quickly) became widespread in print.
All the 12+ ratings of every station making 'the cut' showed up, even those numbers from non-subscribing stations. It has to've been ten years now since the lurking mothership 'Arbitron' decided to utilize a shield to prevent non-subscribers from profiting.
I worked in Philly at the time when the 12+ numbers included all the stations, and I recall things like WCOJ 1420 from Coatesville showing with like a 0.4. Coatesville is three counties west of Philadelphia proper.
In that book, there was WJBR, with (iIrc) a 0.5.
But that was quite some years ago. At the time, I was working at Eazy 101, now WBEB. Before that I had been at Kiss 100 there, another soft A/C.
Well, jumping into that pile came WSNI (now WRFF). I'd do my homework, mostly a music monitoring, by tuning in all of them.
Of the four stations, I considered WJBR to be the best-sounding -- the most 'authentic', for lack of a better word. I don't mean in terms of fidelity ; I have one good ear. They had, and have, a huge signal as well. But I regarded them as the best of the four soft A/C's on the dial ... professional, tight, almost aloof. They definitely deserved their 0.5 share. Shoulda been more, imo. But Philly proper had three more 'local' approaches to the same basic format.
