The Portable People Meter (sometimes mistakenly "Personal People Meter") or PPM, is a device developed by Arbitron to measure how many people are listening (or at least exposed) to individual radio stations and television stations, including cable TV. The PPM is worn like a pager, and detects hidden audio tones within a station or network's audio stream, logging each time it finds such a signal. It has proved to be much more accurate than the old handwritten logs or wired meters, and is immune to forgetful test subjects. http://en.wikipedia.org/wiki/Portable_People_Meter
