Yes, correct.I’m not David, but what's most important is the AQH. The advertisers generally buy based on the AQH in the demos they’re trying to reach. At least when speaking of agencies, they buy rating, not share.
And rating, share and AQH persons are the same thing, expressed in different ways. And agecies have started buying AQH persons so they can compare with the “reach” of web programming.
Come driven ratings are stations that have lots of people who don’t listen as long. AQH driven fume stations have fewer listeners, but longer TSL. A CHR will have high cume while Urban AC will have high TSL with fewer listeners.I've been told selling cume driven ratings is easier than selling numbers driven by TSL. Neither, however, is a sales metric in and of itself.
An agency buying “reach and frequency” will want a good average of both.
