Portable People Meter
Responding to requests from its customers—radio broadcasters, ad agencies and advertisers—that expressed their interest in the collection of more accurate ratings data, Arbitron introduced the Portable People Meter (PPM) service in 2007. The PPM is a wearable portable device much like a pager or cell phone, that electronically gathers inaudible codes that identify the source of a broadcast, such as a radio station. Arbitron recruits and compensates a cross section of consumers to wear the meter for an average of one year and up to two years.
