“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!’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.

“This announcement is consistent with our goal to create the leading advertising marketplace and give our advertise rs the ability to connect with their target customers wherever they are on the Internet,” said Hilary Schneider, executive vice president of the Local Markets and Commerce Division and the Yahoo! Publisher Network Division at Yahoo!.

” 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! 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. Search services and Comcast Interactive Media’s other properties are not part of the partner ship.
