From BBM

On September 23, 2002, BBM Canada announced that Quebec francophone broadcasters have given their overwhelming support to measure the Montreal francophone television market electronically using Portable People Meter (PPM) technology. This historic announcement marked the PPM's first commercial application in Canada.

The Portable People Meter, developed by Arbitron Inc., is a pager-sized device that is carried by a representative panel of television viewers. It automatically detects inaudible codes that broadcasters embed in the audio portion of their programming using encoders provided by BBM and Arbitron. At the end of each day, the survey participants place the meters into base stations that recharge the devices and send the collected codes to BBM for tabulation. The Portable People Meter can measure exposure to any electronic media, which has audio that can be encoded – television, cable, and radio, even cinema advertising and in-store media.
