NetRatings Buys ACNielsen's eRatings.com Stake

Advertisement

NEW YORK -- NetRatings continued its acquisition binge this week, acquiring ACNielsen's stake in ACNielsen eRatings.com, a service that tracks audiences, advertising and user activity on the Internet globally.

The Milpitas, Calif.-based Internet audience measurement firm, which already owns a 19.9-percent stake in ACNielsen eRatings.com, said that it bought the remaining portion from ACNielsen for 749,341 shares of NetRatings stock, worth $9.6 million.

The acquisition comes on the heels of NetRatings settling a patent infringement dispute with Jupiter Media Metrix, which called for the former to purchase latter's computer-use tracking patents for $15 million [IQ Daily Briefing, May 7]. On Monday, NetRatings bought DoubleClick's @plan for $18.5 million [IQ Daily Briefing, May 6] and last month the company acquired substantially all of the assets of the AdRelevance division of Jupiter Media Metrix for $8.5 million [IQ Daily Briefing, April 10].
