The PPM is not perfect, but I don't think it "targets" anyone. The big stations do better than the little
suburban stations because they cover more people, particularly in Allegheny County, and in the city of
Pittsburgh proper. That's just simple mathematics.
Note also that PPM has remedied what the radio industry called "phantom cume." Frankie Day now has
a consistent (if relatively small) share every month. Some other stations I would expect to show up in
the ratings (like WLSW) probably are not encoded.
I believe it is an accurate measurement of audience. It's certainly more accurate and less biased than
the diary system, which was much more easily manipulated, and in its most recent forms shortchanged
several formats.
