IDG Online Sites To Offer Industry’s Most Rigorous Management System For Analyzing And Targeting Multi-Site Online Campaigns For Global Advertisers

BOSTON, MA – MAY 21, 2001 – International Data Group (IDG), the world’s leading provider of IT media and information services, today announced that in April alone, more than eight and half million unique visitors accessed IDG’s global network of sites to obtain technology information. This measurement is based not on syndicated or panel-based surveys, but on tracking actual site usage page-by-page across IDG's global online network. This measurement is available using the DART (Dynamic Advertising Reporting and Targeting) system from DoubleClick (NASDAQ: DCLK).


DART is the leading outsourced advertising management service, used by thousands of publishers and advertisers worldwide. The service provides IDG with the ability to analyze advertising campaigns across its network of more than 300 web sites, target campaigns based on specific advertiser requests, and reliably generate campaign performance reports. In addition, by utilizing DoubleClick’s DART Technology, IDG is able to gain a snapshot of its unique online visitors by counting page views across its worldwide network of sites.

"As global Web advertisers become more sophisticated, they are seeking more detailed information to help them evaluate their online marketing investments," said Kelly Conlin, president and CEO of IDG. "By working with DoubleClick, IDG's global advertisers placing multi-site ad campaigns benefit from having access to consistent measurements of unique visitors to IDG's sites."

Global IDG advertisers placing multi-site ad campaigns across several regions will also benefit. With DART, IDG is able to generate statistics on the success of a campaign from one consistent, systematic source instead of current industry or "home grown" solutions that rely on multiple calculations from different sources.

IDG’s global network is the world’s most powerful online source for technology information. In fact, with its premium online IT content, IDG reaches more technology buyers than any other global media company. IDG’s online network targets distinct computing communities – from game enthusiasts to Internet executives, from CIOs to CTOs, from Java developers to business managers. The online network is also supported by the world’s only global IT news organization, featuring more than 2,000 journalists in 85 countries, giving users access to news from every corner of the globe.
