PPMs Track Podcasts, Too, Says Arbitron

Arbitron said that it has successfully demonstrated the portable people meter's (PPM) ability to track listening to podcasts, according to Billboard Radio Monitor. In a test during the week of July 18, Arbitron encoded several podcasts from Clear Channel's WHTZ-FM (Z100) in New York that were uploaded to Apple's iTunes Music Store. The podcasts were then downloaded to an MP3 player and played using headsets with the PPM headset adapter.
