PPM Receives MRC Accreditation in Riverside-San Bernardino

January 9, 2009

New York - Jan 9, 2009 - The Media Rating Council (MRC) has accredited the Arbitron Portable People Meter radio quarter-hour ratings data in Riverside-San Bernardino. The sample used a telephone-based sample frame and telephone recruitment with landlines and cell phones.

Arbitron voluntarily submitted data to the Media Rating Council process and is following the requirements of the draft Voluntary Code of Conduct (VCOC), which requires, at minimum, that a measurement service seeking to replace an existing accredited currency product in a market submit the replacement product to a rigorous independent audit and that the results of the audit are shared with customers who are members of MRC prior to commercialization of the replacement product. The VCOC also requires a period of comparison data for customers to evaluate.
