Bye, bye diaries! Here's the PPM rollout schedule
Arbitron's schedule to convert all of the top 50 markets to Portable People Meter (PPM) measurement by late 2010 means that many radio station operators will soon be facing a decision. An Arbitron spokesman tells RBR that the company's contracts allow it to change methodologies and to raise prices when it does so. The catch is that it triggers an out for the station, which can cancel its Arbitron service. Early on, markets will generally have a one book overlap with both diary and PPM measurement. But then, Arbitron assures us, it will be PPM or nothing - - at least nothing with the Arbitron stamp of approval on it. Here's the roll-out schedule.
