Re: PPM is not that different.

happiness is a PPM in San Francisco.
So the ratings can actually be accurate, not just 1,500 cards filled out by old white women and at times a handful of men in the demos that matter....
The ratings system is a joke ... and if im not correct summer 08? we are gonna have PPM's??!?
PPM starts in San Francisco (and the embedded San Jose and Santa Rosa markets) in April of 2008. The first of the 13 annual "reports" (there are no books any more) will come out in May, 2008 and another will be out every 28 days. We will also have weekly condensed reports, too.
Based on the last 5 years of testing in Philadelphia and Houston, there are no significant share changes in the PPM compared to the diary. In fact, the Philly tests three years ago showed that the diary is a perfectly good method for measurement.
The major change is that the PPM tracks both listening and hearing, so small incidents increase station cumes... incidents that would not get written in a diary. Cumes increase a lot, so TSL falls... but shares are pretty consistent between methods.
The reason for the PPM is not accuracy. It is a combination of factors. First, the difficulty in finding diarykeepers... nearly 8000 every 3 months in San Francisco. Compare that to the roughly 2700 meter panelists needed per year! Second is the advertiser request for more immediate delivery. The PPM can give a report that is as accurate as an 84 day diary survey every week!
While I know you exaggerate, the diary methodology attempts, and pretty successfully, to achieve proportionality in all demos, ethnicities, etc. In other words, there is no excess of "old ladies" vs. teens or 18-34 women and so on. Heck, they even get very good proportionality on Spanish dominant vs. English dominant Hispanics!
