Comcast and Yahoo! Join in Advertising Network

Philadelphia, Pennsylvania - Search Engine Marketing May 3, 2007 - Comcast.net, Comcast Corporation's Interactive Media, has joined search engine, Yahoo! Inc., in a multi-year strategic partnership for online display and video advertising services.

Hilary Schneider, Executive Vice President of the Local Markets and Commerce Division and the Yahoo! Publisher Network Division at Yahoo! added, ''This announcement is consistent with our goal to create the leading advertising marketplace and give our advertisers the ability to connect with their target customers wherever they are on the Internet. With Comcast's high quality broadband audiences, trusted brands can effectively extend their reach and impact as we continue to deliver our advertisers' most relevant marketing messages to the most highly qualified audiences at the right place and time.''

Yahoo!'s advertising sales organization will be the primary marketing and sales channel for Comcast.net display and video advertising. Comcast.net will tap into Yahoo!'s extensive network of leading brand advertisers and benefit from Yahoo!'s sophisticated ad-serving, targeting and inventory management capabilities to enable the pricing, targeting, delivery and reporting of display and video advertisements. Comcast Spotlight will continue to bundle Comcast.net in cross-platform and locally-targeted advertising packages to its growing base of local, regional and national advertisers through its existing sales force of over 3,000 sales executives.

Amy L. Banse, President of Comcast Interactive Media remarked, ''We are delighted with our new long-term strategic partnership with Yahoo!. Their scale, experienced sales force, advertiser relationships and industry leading display advertising capabilities will bring significant new monetization opportunities to Comcast.net. As Comcast continues to grow its online presence we will monetize our other online sites while driving innovative cross- platform services and creating new business models.''

Yahoo! and Comcast Interactive Media will collaborate to create and market new sponsorships and custom advertising packages that are supported by Yahoo!'s platform. Yahoo!'s advertising services will be integrated within the redesigned Comcast.net planned later this year. The redesigned Comcast.net will include enhanced features, user experience and new advertising opportunities across the site.
