PPM (Portable People Meter)
A Portable People Meter (PPM) is a small device used to measure radio and television audience engagement. Participants carry the PPM, which detects audio signals from stations they listen to or watch. This helps researchers collect data on what content people consume, providing insights into audience preferences and behavior. The PPM is crucial for broadcasters and advertisers, as it helps them understand audience trends, improve programming, and target their advertising more effectively. It offers a more accurate picture of media consumption compared to traditional surveys.
