Integrated Media Measurement Inc. and the Nielsen Co. have launched a service that electronically measures out-of-home viewership of television shows. The system gives viewers in a pre-selected panel special cell phones that pick up the audio from programs (as well as radio broadcasts and movie soundtracks). Nielsen and IMMI released figures for July showing the programs that had the biggest out-of-home viewership.
