Eight markets — New York, Nassau-Suffolk, Middlesex-Somerset-Union, Los Angeles, Riverside-San Bernardino, Chicago, San Francisco, and San Jose — will commercialize with the release of the September PPM survey report on Oct. 8, Arbitron said.
On that date, the company’s diary-based radio ratings will be withdrawn from those eight markets and radio transactions among Arbitron-subscribing stations and agencies will take place solely using PPM-based radio ratings.
The audience research firm will deliver “pre-currency” PPM survey reports for Los Angeles, Riverside-San Bernardino and Chicago with a special release of the June PPM survey report in mid-July, and with the regular release of the July PPM survey report on Aug. 13 and the August PPM survey report on Sept. 10.
