Survey Schedule for Diary and PPM Services: 2006 & Beyond

Arbitron presently conducts radio ratings surveys using one of two methods: Diaries or the Portable People Meter (PPM™).

Arbitron's diary-based radio surveys are conducted over a 12-week period. There are four 12-week surveys per year (winter, spring, summer and fall), totaling 48 weeks of radio measurement. Arbitron audience estimates represent radio listening during an average week of a particular quarterly survey period. Markets that are part of Arbitron's Small Market Initiative receive a two-book average of the most current survey and the previous survey.

Arbitron's new radio audience measurement system, the Portable People Meter (PPM™), is currently being rolled out as a radio ratings service. The PPM service is replacing Arbitron's diary-based ratings; existing plans call for the PPM to be deployed in the Top 50 radio metros by 2010 (to see the PPM™ rollout schedule, go to www.Arbitron.com). PPM™ markets have year-round measurement; there are thirteen monthly reports (including a winter holiday report), as well as weekly reporting.
