It’s not competing with Nielsen for local or even national ratings. But it’s leveraging its People Meter technology to sell research about what Americans watch out of home, in a service called “ARB-TV.” Arbitron EVP Alton Adams says the suite of services “helps quantify audience viewership in locations outside of the home, including, among others, restaurants/bars, other homes, the workplace, airports, hotels, sports venues, malls and medical facilities.” Away-from-home is a perceived weakness of the established Nielsen system. Arbitron is thus selling data it’s already gathering from its increasing army of PPM-wearers in larger markets – an army that will add participants in Miami, Seattle, Phoenix, Minneapolis and San Diego starting with the June “book.” Arbitron may be reacting to Nielsen’s own push into its turf, offering radio ratings in 51 smaller markets, with the first data due in August.
