Nielsen, 4INFO To Measure Mobile Ads

Two years ago, Nielsen Co. combined its media data expertise with Catalina Marketing’s research into shopper behavior to form Nielsen Catalina Solutions. The combined entity¹s first offering was a service measuring TV industry return on investment. Now, mobile ad company 4INFO said it is combining Nielsen Catalina’s tracking of shopping purchases from 60 million households with its own tracking data from over 70 million unique mobile users.
