TV People Meter: Monitoring What You Watch

bj3g2j writes "CNN has an interesting article about the People Meter that is built by Arbitron. It seems that the device is portable and picks up on signals sent from the TV (and/or radio) to determine what people are watching. This is supposed to improve the accuracy of tracking viewer habits. The best quote is that 'it includes a motion detector to verify someone is actually wearing it.' Lots of motion while sitting on the couch? Interesting concept in light of the recent ruling in California."
