Nielsen Bows out of PPM Measurement

Published on March 01, 2006
Nielsen announced today that it will not go into business with Arbitron to deploy the PPM (portable people meter, which automatically registers radio and TV signals within a given range of the subject), choosing to take a "portfolio" approach to TV ratings. That approach will be a combination of its LPMs (local people meters, which viewers have to log in to) with DVR data and the expansion of its national sample to include out-of-home viewing by college students.
