I'll agree when you are ranking individual stations and dayparts.
The sample size can't be depended on to tell you accurately who's
in 5th or 6th place, 18-24 males, 10A-3P, for a single week.

But for a massive number like total market listening cume, the PPM
should be fairly accurate, especially considering that the number
doesn't vary too much from week to week over the course of a
year.  It's obvious that an extremely high number of young listeners
spend hours every week with radio.

Bill said he got $5 a month, but I've heard of payments much higher
for younger demos and hard-to-get ethnic groups.  Plus, Arbitron
chooses entire families to participate, so a household might earn
several hundred dollars for taking part.  I do agree there's probably
a bias against non-listeners.  If you consistently sent reports of
zero listening, you'd probably get kicked off.  But that doesn't
exclude low-level listeners who would drag down the average TSL
(now called Average Weekly Time Exposed), and 7-10 hours of
average listening is still a hefty amount.

As an advertiser or a programmer, you don't really care if the
listener LOVES the program, your goal is to get them to hear the
program and the ads that accompany it.  But that's the way it's
always been, except with diaries you had to get listeners to
remember the call letters.  Now, you're getting a more accurate
count of who's in the room, hearing the radio and the ads.  It
doesn't really matter if they have control over the radio dial.  One
goal of programming for PPMs is to create a station that dial-
owners (in stores, workplaces, etc.) will play for captive audiences.

Of course they don't hear every word, just like a Sunday Globe
reader might toss out a section without reading it, or an
American Idol viewer might fast-forward the DVR or head
for the bathroom.  Actually, passive listeners are much more
likely to be exposed to an entire ad than people who are sitting
next to the button on the car radio, so maybe an advertiser wants
them even more.
