I think you missed my point, but you also bring up another good one.
1. How is it that at least commercially, AAA is aging out when the three major components of the format, Hot AC, Alternative, and Classic Rock, are still fairly healthy? I really don't understand how if we were looking at this 10 years ago, KINK/Portland and KLCK/Seattle could have attracted drastically different audiences when probably 80% of their playlist was similar.
Keep in mind that the target listener of a AAA station is a roughly 35 year old woman. What were 35 year old women listening to in 2000? What does the average 35 year old woman listen to today? How much of what they listen to today would work on a AAA station? How much of a AAA's gold library would appeal to a woman born in 1990?
