MRC signs off on four more Arbitron PPM markets

US — Radio measurement firm Arbitron has received Media Rating Council accreditation in four additional markets for the average-quarter-hour monthly ratings data produced by its Portable People Meter system – however 30 markets remain unaccredited.

The newly-accredited markets are Chicago, San Francisco, San Diego and Charlotte-Gastonia-Rock Hill, bringing to 18 the number of markets that can display the MRC double checkmark.

As for the unaccredited markets, Arbitron’s chief research officer Gregg Lindner said the company remains “focused on our efforts… to achieve service-wide accreditation for all PPM markets”.

Arbitron has agreed a $1.3bn deal to be acquired by Nielsen. Yesterday, Nielsen and Arbitron announced that they would give the Federal Trade Commission more time to review the proposed takeover by voluntary withdrawing and re-filing the relevant merger documents.
