Universal McCann Interactive, Modem Media, Starcom IP and Optimedia Among First Users

NEW YORK, June 11, 2003 – DoubleClick Inc. (Nasdaq: DCLK), the leading provider of marketing tools for advertisers, direct marketers and web publishers, and IMS, the largest international provider of information systems for the advertising industry, today announced that the WebRF reach and frequency tool is now linked to DoubleClick`s MediaVisor product. WebRF, jointly marketed by IMS and Nielsen//NetRatings, is the industry`s leading respondent level reach and frequency planning tool for Internet audience measurement.

This integration enables customers who subscribe to Nielsen//NetRatings data to seamlessly transfer information between the two systems, forecast a campaign`s delivery and execute it through a synchronized interface. Shared customers can now access reach and frequency results directly from the MediaVisor environment. In addition, IMS WebRF users can export lists of Internet properties into DoubleClick`s MediaVisor product for further evaluation.

Clients such as Universal McCann Interactive, Modem Media, Starcom IP and Optimedia, are among the first users to access the IMS reach and frequency tool and the Nielsen//NetRatings data through DoubleClick`s MediaVisor product. This allows them to access Internet media planning and research data using reach and frequency metrics similar to print, radio and television advertising.

“This integration has allowed us to more accurately incorporate reach information in our upfront planning process,” said Brenda Goodman, SVP, Media Director, Optimedia. “Being able to export this data into our planning tool allows us to begin to have similar metrics when evaluating goals and optimizing our media mix.”

MediaVisor is a hosted, web-based media planning, buying and campaign management workflow solution designed to help agencies plan, execute and analyze their interactive marketing programs. This tool automates time-consuming, repetitive administrative tasks, such as RFPs, Insertion Orders and flow charts. MediaVisor is fully integrated into DoubleClick`s DART for Advertisers (DFA) solution, a hosted, enterprise-class advertising management and serving solution, which helps advertisers reach their online goals efficiently and effectively. This integration allows agencies to manage its online campaigns through one central system.

“The ability to assess the potential of the Internet in standard media terms facilitates the likelihood that the Internet can and will be evaluated with the same commitment as other media,” said Amy Betz, VP Media Sales Solutions, IMS. “It allows for more efficient campaign management through the use of integrated research, planning, buying and post buy analysis tools.”

This integration marks an ongoing relationship between the two companies. Most recently, in March of 2003, DoubleClick announced the results of its Cross Media Reach and Frequency initiative, which was designed to demonstrate the impact of shifts in media allocation on audience reach. The study used Nielsen//NetRatings data and the IMS multi-media tools, which enable cross media planning and extend traditional reach and frequency analyses to online advertising. The study found that by increasing online spend, American Airlines, Subaru and Kraft could increase their reach of light television viewers.

“Over the last two years there has been a tremendous amount of interest in an online reach & frequency tool, which would allow advertisers to be able to use similar planning metrics across multiple mediums,” said Doug Knopper, Vice President and General Manager, Online Advertising Solutions, DoubleClick. “As the leading provider of marketing tools for marketers and web publishers, we are committed to providing these types of cutting-edge solutions that allow advertisers to truly understand the value of the Internet compared to other mediums.”
