Aside from a small page 2 mention in R&R Today, there's been little notice of RAJAR's abandonment of PPM. RAJAR, Radio Joint Audience Research, is the UK's radio ratings system. You may recall that the very first test of PPM was in Great Britain, and British broadcasters have done more systematic testing of electronic measurement than any other organization. In addition to PPM they've tested the Eurisko Media Monitor, the IPSOS audiometer, and others.
Explaining their decision, RAJAR writes:
The pilot has delivered a wealth of data but it has continued to high-light serious concerns with respondent compliance, particularly at breakfast time. In addition, the pilot has thrown up a range of concerns involving sample sizes, panel composition and the practicalities of operating a panel for the entire UK radio market.
Instead of electronic measurement, RAJAR has decided to pursue an on-line diary methodology. The entire RAJAR press release is interesting reading. Coverage of PPM in the US has been essentially press release journalism. Neither the trade publications nor organizations that ostensibly represent radio stations like NAB or RAB have taken any interest in an objective assessment of PPM. The RAJAR press release is a dispassionate and objective review of where radio measurement stands today. The Press Release can be found here.
