True, though look at the rest of that list for Milwaukee. 80% of the
top-10 stations are FM. Only 53% of all radio stations (not counting
non-commercial) in the Milwaukee market are FM. There's a lot of AM
stations being left out.

A similar situation exists in other markets. In many (14 of the top 35)
markets, an AM station is #1. However, in 11 of the top 35 the
top-ranked AM station is the ONLY AM in the top 10, and in no market are
there more than three AMs in the top 10. (unless you count the AM side
of an AM/FM simulcast)

I guess the point is, an AM station can be successful but ONLY if it has
the signal to fully cover the market. The vast majority don't.

(it may also be instructive to note that of the 45 AM stations to make
the top 10 in the 35 largest markets, ALL of them run news/talk formats..)
