No. That sounds like old-fashioned hyperbole. The whole station has a Summer book cume of 177,000 and the average and they have another 20,000 between Rochester and Olean. Add a few thousand more from streaming, and you have just around 200,000 total station persons.
No terrestrial station in the US cumes 8,000,000 persons. Shannon, in NYC, cumes between 700,000 and 750,000 and that is about as good as you are going to get in that kind of format.
WYRK's AM drive averages under 12,000 AQH ´persons, with a cume of just over 100,000.
