In testing so far, the companies have used a national pilot panel
of about 11,000 people in 5,000 households that provides data to a select group of customers. PPM collects information on exposure to network radio, broadcast TV and cable networks, while Homescan
tracks purchase pf packaged-goods.
"By making it possible to link the Arbitron Portable People Meter system with ACNielsen Homescan technology, this agreement between Arbitron and The Nielsen Company will help make real the industry's long-standing dream of a true, "single-source" consumer research service," says Arbitron President & CEO Steve Morris.
