This would be why 6 of the top 10 billing stations in the USA are AM? 17
of the top 40 stations? Including the second and 4th highest billers in
the US?
Just an aside: Which are the six top-billing AM stations in the U.S. and
how are they spread throughout the top 10? I'd guess that WGN is one of the
six, but not having any data at hand, I can't make a really good guess on
the other five.

Thanks
