«New York - Jun 25, 2007 - The radio industry in Denmark has selected the Arbitron Portable People Meter (PPM) system as its electronic audience measurement system. The five-year contract was awarded to TNS Gallup, an international licensee to the Arbitron PPM technology. Beginning in January 2008, a national panel of 750 Danish consumers will be equipped with the Arbitron PPM to collect overnight radio listening data. Danish broadcasters will analyze the ratings at one-minute increments and use the data for commercial sales and for program planning. The PPM encoding system will also be used by the Danish television industry beginning in the fall of this year to identify the programming sources for the set-top push-button people meters operated by TNS in Denmark. Since 2001, TNS has also used the Arbitron PPM in Singapore to identify the programming sources in set-top push-button people meters. » (fonte: Denmark Radio Selects Arbitron PPM RadioCurrents On line, 25/06/07)
