Shocker: PPM is Not 100% Accurate!

Ben Fong-Torres is one of my heroes, so it’s always a pleasure to read his stuff, even when he’s writing about something as workaday (to you and me) as Arbitron’s PPM.

A couple weeks ago he profiled a real, live, in-the-flesh PPM panelist.  And he discovered pretty much what any sentient being in radio (no jokes, please) already knew:

PPM does not perfectly collect all listening in all situations.

To quote the wry, late, and great John Gielgud, “alert the media.”

While this story is interesting to the lay reader who knows nothing of the measurement side of the radio business, no broadcaster should be surprised by a word of it.

“Pagers are like ’80s things,” said the panelist.

You bet they are!  Then again, diaries are like ’30s things, so maybe there’s more progress here than meets the eye.

“[Arbitron] said they’d had difficulty finding people in this area in my age range.”

You must be over the age of 5.

“But I wouldn’t take [the PPM device] to some occasions, like out to dinner.”

Smooth Jazz is going to Hell in a handbasket.  Check.

It’s easy to declare DefCon 1 and bemoan that “lost listening” is going unrecorded, but I say we all have to get over it.

That’s because PPM is a procedure to sample behavior and create estimates of usage.  Like all research, it is a best guess on reality, an abstraction of the truth. While you can make any research methodology better, you can never make them perfect.  They will always be just what they claim to be:  Estimates.

There will always be “lost listening” or exaggerated listening or incorrect listening or bad distribution of measurement devices or even diarykeepers who just can’t seem to find a #2 pencil when they need one. Such is the nature of the beast.

We should not freak out when a PPM panelist discloses obvious and well-worn truths.

Our larger challenge is to ask ourselves how we expect to prove the performance of all that listening as it relates to results for our advertisers.

It’s to ask ourselves how we can leverage that listening into profit opportunities which follow the flow of ad dollars out of mass media and into digital platforms.

It’s to ask ourselves how we can be not just present in listeners’ lives but a vital force that they care about passionately.  One that’s not replaceable on any platform.

These are not questions for PPM panelists, folks.

They are questions for radio industry executive boardrooms.

    Hi Mark,

    I’m not ready to roll over and say the industry just has to live with PPM when the ‘estimates’ aren’t even close to reality a lot of the time.

    ‘You can never make them perfect’ but you sure can try to make them reliable.

    Arbitron is the HMO of research and behaves just like one. Make a profit and the patient be damned.

  • Here's Fred Jacobs' take on this very same issue.


    Funny that we came to pretty much the same conclusion independently.

    too colloquial? 😉

    Seriously though, the question I always had about PPM (and the Diary) does it produce better quality radio?

    We know the measurement method greatly influences radio programming. Anyone that denies this is a liar – or working in Public Broadcasting. 🙂

    But one thought keeps occurring to me. Television has been under electronic, by the minute type measurement for quite some time. I don't sense the same race to the bottom that radio seems to be on.

    Sure, there are loads of cheap, easy, lowest common denominator TV programs that would roughly equate to what's on typical commercial FM radio right now.

    But where TV differs from radio (imo) is all that low rent stuff exists along side some of the most refreshing and innovative Television programming ever.

    Seriously, has there ever been more high quality programs on Television than there are today?

    Somehow, Television execs under the same minute by minute rating measurement pressure (with arguably far more money on the line) can green light highly demanding risky shows like Lost (and many others)

    Meanwhile – radio is retreating – defensively playing it safe by playing the hits, just the hits and only the hits.

    What's the difference? The only thing I can think of is the huge culture of artists – writers, actors, producers, etc…. that are passionate about creating great television. TV still has a vibrant creative community.
