Survey Schedule for Diary and PPM Services: 2018 - 2019
Nielsen Audio conducts radio ratings surveys using one of two methods: Paper Diaries or the Portable People Meter (PPM™).
Nielsen Audio’s diary-based radio listening surveys are conducted over a 12-week period. In the larger markets, there are four 12-week surveys per year (winter, spring, summer and fall), totaling 48 weeks of radio measurement. In medium to small markets, there are two 12-week surveys per year (spring and fall), totaling 24 weeks. Markets that are part of Nielsen Audio’s Small Market Initiative receive a two-book average of the most current survey and the previous survey.
Nielsen Audio’s radio audience measurement system, the Portable People Meter (PPM™), is used within the Top 50 radio metros. PPM™ markets have year-round measurement; there are thirteen monthly reports (including a winter holiday report), as well as weekly reporting.
