According to media research firm COLEMAN’s latest report, “Early PPM Insights, individual radio station ratings performances vary significantly between ARBITRON’s “traditional” diary measurement system and the new PPM measurement system being tested in HOUSTON. The report, which was released today, features a comparison of ratings data from the HOUSTON market, and also includes a comparison of the HOUSTON findings with findings from an earlier test of the PPM system conducted in PHILADELPHIA.
COLEMAN’s “Early PPM Insights” report includes the following conclusions:
- The 12+ AQH share differences between diary and PPM are more dramatic in HOUSTON than they were in PHILADELPHIA.
- Commercial English-language music stations in HOUSTON benefit the most from PPM vs. diary measurement.
- Almost all stations in HOUSTON have larger cume audiences in PPM than in diary, but commercial English-language stations experience larger than average cume increases.
- All HOUSTON stations have lower TSL in PPM than in diary, but Spanish language stations generally experience larger declines in TSL than do English language stations.
