New York, NY, 12/15/01 - (NASDAQ:DCLK), the leading digital marketing solutions company, and Unicast, developer of the SUPERSTITIAL®, the Internet's Commercial™, today announced the completion of a combined effort to enable DoubleClick’s DART for Advertisers service to deliver and report on Unicast SUPERSTITIAL ads.

This integration enables both DoubleClick and Unicast’s advertiser and agency customers to include SUPERSTITIAL campaigns in their centralized DART reports used to track the results of their online campaigns. DART for Advertisers customers can now take advantage of conversion reporting, including post impression tracking, to help evaluate the performance of SUPERSTITIAL ads, along with other forms of rich media and graphic banners.

In addition, this integration enables SUPERSTITIAL impressions to be included in the campaign reach and frequency reporting also available in DART, providing a more complete view of campaign breadth.

"The SUPERSTITIAL is an integral component of the online advertising strategies we recommend to our clients," said Aimee Reker, Media Director, Circle.com. "The integration of the SUPERSTITIAL into the DART system will increase accuracy, flexibility and efficiency in campaign tracking and reporting for all parties involved.”

Simultaneously, DoubleClick has designated Unicast with gold certification to serve SUPERSTITIAL ads through DoubleClick’s DART service. The DART Rich Media Vendor Certification program, which was launched in October 2001, ensures that rich media creatives meet certain standards of support and reporting to help marketers identify those rich media vendors that are compatible with the DART 5 platform. Gold certification is the highest level of certification available.

“We have a high percentage of customers in common with Unicast and are delighted to provide them centralized reporting that will now include the performance of SUPERSTITIALs,” said Andy Ellenthal Director of Sales and Business Development Americas for DoubleClick's Technology Solutions for Advertisers. “Unicast is only the second vendor to achieve Gold DART Rich Media Certification, and we are proud to have them as part of our program.”

“Unicast and DoubleClick have been partners for nearly two years, and this integration is an important step forward in our relationship,” said Allie Shaw, VP Global Marketing, Unicast. “Propagating standards that streamline the online advertising process for all of our constituents – agencies, advertisers and Web sites -- is at the core of Unicast’s mission. The ability to track SUPERSTITIAL ads through DART for Advertisers is something our advertisers and their agencies have been looking forward to. We are pleased to be able to respond to this demand and expect that the result of our joint efforts will surely impact the online advertising economy.”

The DART for Advertisers service is part of DoubleClick’s TechSolutions division, which along with the DART service for Publishers and the AdServer software solution, provides comprehensive service and software solutions for over 2,000 marketers worldwide.
