Bye Bye P-1 Report, Hello Cluster Analysis "Junkies"

It has been fascinating to watch Nielsen decide to stop offering a report that was created almost thirty years ago even as radio researcher Mark Kassof released a report that indicates almost exactly the same statistical relationship of a radio station's heaviest users to their total averages.

35% of all listeners, multivariate data pioneer Kassof finds, account for about 70% of all listening for the typical radio station.

As "Research Doctor" Roger Wimmer and longtime researcher Pierre Bouvard recall, a bright programmer/researcher - Gary Donohue - originated the concept of segmenting radio tuning into quintiles for programming and marketing.

Donohue's "Fingerprint" stats from back in the diary-only days proved that about 30% of radio listeners gave stations roughly 70% of their listening.

When you see two completely different research approaches yield very close to the same result over a very long period of time, you have to believe that you are approaching that rare entity:  THE TRUTH.

Just because Nielsen has unplugged the "P-1 report," it's still vital to know who your heaviest users are, where they live and how they perceive and behave.
