Not only that, the ratings that count...ARBITRON, now more accurate than ever with PPM technology, show terrestrial listenership STRONGER than was thought to be the case when ratings were done exclusively with the paper diary method.
Yeah.... right...
Philadelphia has 2,037 PPM users with about 1800 actually complying.... for such a large city!
Houston the only other city doing this is 2,076 PPM users with only 1930 actual users complying for another large city!
At those rates, it sure indicates how many on average is listening to terrestrial radio!
Not much better than the paper method if you ask me, not only that but it doesn't indicate whether these listeners use other non-radio devices since they are not encoded, thereby giving false results!
So why would Bridge Ratings be any different on a survey based system!
