Richard Harker has been blogging some important questions about the current state of radio ratings (Arbitron, We Have a Question: What Happened to the Button-Pushers?), such as:
When PPM identifies a radio station and then the audio switches to an unidentifiable source, it is recorded as a switch to non-encoded media. No more radio credit is given. But what if the participant really just switched stations, but PPM couldn't identify it? Could this explain lower listening estimates and the absence of button pushers with PPM?
Now, I’d like to add a few more of my own:
Nielsen research from their Lexington diary test earlier this year found cell phone-only households are heavier radio users, while Arbitron has reportedly come to a totally different conclusion. Their new spokesperson told Inside Radio yesterday “There does not appear to be different listening behavior.”
Are the differences based on diary measurement vs metered usage? Or, is there really no difference in radio usage between the kind of people who would not have a land line home phone and those who do? Who’s right? How can we know for sure? Will Nielsen and Arbitron (or the RAB?) fund an academic study of this?
When Nielsen announced their 2009 radio survey in the U.S., they talked about releasing the data in June. Now, company insiders say they are working toward a tentative launch date of August 17, which just happens to be three days after the last Spring 2009 Arbitrons have been released.
Why the change, in spite of the fact that Nielsen’s local market surveys started and ended a month before ARB’s?
Nielsen, it seems, has chosen to have the luxury of seeing ARB’s Spring 2009 local market reports before they give ARB a look at their data in the markets they both have been surveying this spring.
Why keep their Cumulus and Clear Channel subscribers waiting for the data like this? Or, are subscribers seeing the first Nielsen radio data this month and were they a part of the decision to delay the release?
In Canada, where BBM is discontinuing their use of Nielsen TV meters, lowering their client TV station subscriber rates as they embark on using PPM for all media measurement, keeping radio rates the same as they have been for diary surveys (unlike Arbitron which is charging 60% more), diary sample proportionality in market after market is causing hair-raising levels of weighting - making for wild book-to-book swings.
Has BBM already done the replication study I am asking about? Or, are they moving ahead with PPM merely because of the economies of scale for their subscribers?
Confusing as all of this is right now, it's good to see so many different approaches being tried by broadcast researchers.
Once all of this data is available to independent observers in the coming year, we're going know a lot more about what's unquestionably fact .. and what's just preliminary theory.
