PPM Presurvey Bulletin,

PPM Release Schedules and Methodology
Additional information on the release schedule for PPM audience estimates and data, and information on PPM methodology, is available at the Arbitron Web site at:

Note: Although all PPM markets utilize methodology that is similar in many respects, Houston-Galveston served as a PPM Demonstration market prior to the start of its conversion into a PPM Currency market. As a result, the Houston-Galveston market employs methodology that may differ in some respects from the methodology in other PPM Pre-Currency and Currency markets. Subscribers may also wish to note that Arbitron’s Houston-Galveston PPM radio ratings data have received accreditation from the Media Rating Council® (MRC).
