AT&T Renews Partnership With InfoSpace to Power Popular MEdia Net Service.

Long-Term Partnership Extension Offers Subscribers Fast, Easy Access to Personalized Information Anytime, Anywhere

BELLEVUE, Wash. -- InfoSpace, Inc. (NASDAQ:INSP), a leading mobile services platform provider, today announced it has extended its partnership with AT&T, formerly Cingular Wireless, to power the carrier's popular award winning MEdia Net service. In addition, InfoSpace will continue to provide AT&T with customized mobile search and messaging solutions, as well as professional hosting and management services. These technologies are components of InfoSpace's innovative Mobile Services Platform, a suite of customizable mobile infrastructure services that include storefronts, portals, search and messaging solutions designed to help carriers offer their subscribers a seamless, simple experience for finding and enjoying mobile content and information on the go, under their own brands.

Since InfoSpace first began powering MEdia Net in 2003, more than 30 million AT&T subscribers have benefited from fast and easy access to personalized information such as e-mail, messaging, games, ringtones, travel and weather information and news. MEdia Net users can create a home page directly on their mobile phone and add content from various categories using one easy-to-navigate dashboard. The addition of InfoSpace's end-to-end mobile search solution will enhance the user experience even further, as subscribers will be able to search for content and information, regardless of its origin or format, using a single search box. The result is a solution that decreases clicks, and provides AT&T the flexibility to bring in vertical specific search partners as necessary.

InfoSpace's Mobile Services Platform provides an end-to-end technology infrastructure to help carriers reduce ongoing maintenance costs, improve customer service, increase opportunities for revenue and simplify the end user experience. Carriers can deploy the back-end technologies into their existing infrastructure in part or as a whole to offer a best-in-class, unified mobile data experience while driving revenue.

"We're seeing an explosion of mobile services in the market and forward-thinking carriers like AT&T are starting to capitalize on the opportunity to offer customers a more streamlined, relevant and personalized user experience," said Steve Elfman, executive vice president of InfoSpace's mobile business unit. "AT&T has definitely been at the forefront of this movement and we look forward to expanding our longtime partnership as consumer demand continues to grow."
