New Global Client for Nielsen//NetRatings Service 28/08/00 Nielsen//NetRatings, purportedly the fastest growing Internet audience measurement service in the industry, has signed up Yahoo! to its service in 14 countries in North America, Europe, Latin America and Asia Pacific. The agreement provides Yahoo! with access to Nielsen//NetRatings' audience measurement service, which provides audience activity information on websites and advertising banners collected in real time from representative panels of Internet users in each country. The NetRatings software monitors panellist activity in real time as they surf the Web, move within sites and are exposed to banners. According to William Pulver, Vice President of ACNielsen eRatings.com, "We are proud to have been chosen by Yahoo! as a global provider of high quality, reliable Internet audience measurement. We have seen tremendous results since we announced the first global Internet measurement service late last year, as buyers and sellers of online advertising have responded enthusiastically to our information quality, our proprietary technology and our patent-pending BannerTrackSM service." "We have chosen to extend our relationship with the Nielsen//NetRatings service to these global markets because the service provides us with the reliable and accurate audience measurement research that Yahoo! needs," added Bruce MacEvoy, director of research at Yahoo!. "Through the Nielsen//NetRatings service we will be able to examine global audience data in new ways. We believe this service will prove to be a valuable investment for us as we continue to expand globally." Yahoo! has subscribed to Nielsen//NetRatings in Australia, Ireland, Japan, Singapore, Canada, the UK, Italy, France, Germany, Denmark, Sweden, Brazil and Hong Kong. The company has been a subscriber to the Nielsen//NetRatings service in the US since 1999.
