Business & Technology Editors

STAMFORD, Conn.--(BUSINESS WIRE)--Oct. 10, 2000

The Danish Association of Advertising & Media Agencies, DRB, has chosen Nielsen//NetRatings, the fastest growing worldwide Internet measurement service, to supply critical information about Internet audiences and advertising.

"The global nature of the Internet means that there is a vital need for a common standard of audience measurement throughout the world and not just in one country," says Soren Kyllebaek, Chairman of DRB. "We believe that Nielsen//NetRatings will give us that international perspective."

DRB's 100 members include such leading Danish advertising and media agencies as Mediacom, Carat, OMD and CIA Media Network.

"We applaud the approach taken by DRB to establish an industry currency for measuring the Internet, and we're delighted that they have chosen Nielsen//NetRatings," says Peter Wilcox, Managing Director-Europe for ACNielsen eRatings.com. "Our technology and methodological rigour will deliver the information quality that DRB and its members require.

"Advertisers are becoming increasingly sophisticated in the way they choose Web sites for their advertising and marketing programs," Wilcox continued.

"Our BannerTrack(TM) service will support clients with unique insights into advertising copy, click rates and audience demographic profiles."

This is the second time this year that the Nielsen//NetRatings service has been selected as the market-leader in a European country. In March, ACNielsen eRatings.com signed an agreement with the Irish advertising association, the Institute of Advertising Practitioners of Ireland (IAPI).

Nielsen//NetRatings is a service provided by ACNielsen eRatings.com (a venture between ACNielsen Corp., NYSE:ART and NetRatings, Inc., NASDAQ: NTRT), Nielsen Media Research and NetRatings, Inc.

Recently launched in the Nordic region, the Nielsen//NetRatings service currently covers Internet audiences and advertising in 14 countries in Europe, North America and Asia Pacific.

The service is expanding rapidly and is scheduled to launch in 18 countries by the end of this year, representing more than 80 percent of global Internet usage. Expansion will continue in 2001 toward the ultimate objective of Nielsen//NetRatings coverage in more than 30 countries, representing more than 90 percent of global Internet usage.
