PPM gets accredited in 11 markets – but 34 are turned down

MRC, the industry’s measurement auditor, has signed off 14 out of a total of 48 PPM markets to date, along with an analysis tool for PPM data. The reasons services fail to be accredited are not disclosed.

Each market is submitted to an annual audit, Arbitron said. Gregg Lindner, Arbitron’s chief research officer, explained: “We will continue to work with the MRC with the goal of achieving accreditation for PPM radio ratings across all PPM markets.”
