The top 15 markets are 93 million, roughly. That's about 38%, not 85%.

You know I've seen that chart from Arbitron too....

Could it be 85% or radio listening is done in Top 15 markets.

That's not true, either. If the top 15 have 38% of the population, about
38% of radio listening is done in those markets.

I'm still trying to reconcile my memory with that fact/figure.... ;-)

Could it be that 85% of America lives in one of the top 15 market "ADI's"?

(Or TV markets?)
