Sonic Foundry Exhibits in Microsoft's Virtual Launch Event for Silverlight 3

MADISON, Wis. - July 10, 2009 - Sonic Foundry, Inc. (NASDAQ: SOFO), a leader in rich media webcasting and knowledge management and the global leader for lecture capture, today announced the company's participation in Microsoft Corp.'s virtual launch event for Silverlight 3. The company, an early member of the Microsoft Silverlight Partner Initiative, will showcase the new Mediasite 5.1 with a virtual booth in the event's exhibition hall. The launch event, expected to reach hundreds of thousands of online visitors, also features keynote and technical sessions, resources and videos within a Silverlight environment.

"Microsoft applauds Sonic Foundry's initiative to offer a fully Silverlight 3-enabled playback experience for lecture capture," said Brian Goldfarb, director of the Developer Platform Group at Microsoft Corp. "Sonic Foundry's commitment to Silverlight 3 is yet another example of how Silverlight helps companies innovate to provide rich and dynamic content for an evolving Web-based clientele."

By harnessing the power of Silverlight, the newest Mediasite Players provide an unparalleled experience for watching online lectures, presentations, training and events. Universities and enterprises can deliver richer, more dynamic content and embed presentations that use Mediasite's new Silverlight players directly within any portal, course management system, website or blog - providing viewing within the sites and applications that users visit most.

"Microsoft has a long history of being the leading video platform in the enterprise and education markets, and with Silverlight's new features, they still lead the pack as the online video platform of choice for Fortune 500 and higher education customers," said Dan Rayburn, principal analyst, Frost & Sullivan. "Sonic Foundry's decision to standardize on Silverlight for its ubiquity and rich user experience enables them to support the broadest spectrum of webcasting and lecture capture users."

"When Sonic Foundry first deployed Silverlight more than a year ago, our customers quickly realized the benefits of utilizing a cross browser, cross platform technology. Today, Mediasite's dynamic, context-based viewing experience allows users to watch and interact with live and on-demand rich media presentations based on what's most important to them," said Monty Schmidt, founder and CTO of Sonic Foundry. "Sonic Foundry will continue to partner with Microsoft because its commitment to innovation and excellence is much like our own. They have a decades-long legacy of customer allegiance and are dedicated to maintaining a solid network of partners. We are proud to be the first company to offer a fully Silverlight enabled playback experience for lecture capture, and to be part of their Virtual Launch event which allows us to share Mediasite with the quickly growing Silverlight community."
