MRC accredits PPM data in more markets.

Story by Inside Radio

The Media Rating Council has given accreditation to Arbitron's PPM-based ratings in Los Angeles, Baltimore and San Antonio for the first time. 

Two other markets – Riverside-San Bernardino and Tampa – are regaining accreditation after losing the status in January after performance metrics declined. 

The MRC has also voted to continue accreditation in nine markets, including Atlanta, Cincinnati, Houston, Kansas City, Milwaukee, Minneapolis, Philadelphia, Phoenix, and St. Louis.
