New Comscore API Enables Direct Integration of Comscore Data With Clients’ Data Systems

New API Offers Great Efficiency and Interoperability Benefits

RESTON, VA, November 15, 2007 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced the introduction of the Comscore MyMetrix Application Programming Interface (“API”), a means by which Comscore clients can retrieve Comscore data in XML format directly from Comscore databases and integrate it with their own internal data sources and systems.

“Our clients ran about 3.3 million reports last year, an 80-percent increase versus the previous year,” said Linda Boland Abraham, Comscore executive vice president of product management. “The Comscore MyMetrix API addresses the growing need to integrate Comscore data with other data sources in an automated and seamless way. As businesses increasingly utilize complex reporting and customer targeting applications based on multiple data sources, publishers and advertisers have a need for an optimized and customizable solution that can deliver critical business intelligence directly to their core marketing planning and analysis systems.”

Some of the key benefits offered by Comscore MyMetrix API include:

Simplified access - Direct access to Comscore databases

Reduced operational costs - Reports that are currently run and downloaded manually every month can now be automated, with minimal intervention required

Customization – Can use in-house report generation tool in addition to standard syndicated reporting interface

Multi-channel data integration, synchronization and centralization - Create holistic view by combining internal reporting systems, CRM solutions and databases with Comscore data sources

Access to archived data - Ability to develop an internal archive of Comscore data that extends beyond what is available through the MyMetrix interface at a given point in time

Increase business intelligence and efficiency - Spend less time running and downloading reports and more time analyzing data and increasing business intelligence

Currently, the Comscore MyMetrix API is available for integration with the following Comscore services: MMX, Local Markets, World Metrix, Plan Metrix, Ad Metrix, Video Metrix and Campaign Metrix. Other services, including qSearch 2.0, will be available in the near future.

“We were very excited to learn about the Comscore MMX API,” said John Sollecito, Vice President, Digital Media Research, MTV Networks. “Our digital research needs require that we integrate MMX data with internal data sources and systems in order to develop the holistic business intelligence we need. The Comscore MMX API enables us to ingest Comscore data very efficiently, allowing MTV Networks to spend more time analyzing and making sound business decisions based on these valuable data.”

The Comscore MyMetrix API can be accessed by any framework that supports connecting to SOAP-based web services, such as Microsoft.NET, Java, Perl, Python, etc.
