Microsoft has launched Silverlight 3 and Expression 3 today. Silverlight is a browser plug-in that enables companies to design, develop, and deliver web apps. Expression is a set of design tools and technologies.

The new Silverlight release in particular is big news. Over 1/3 of Internet devices have installed version 2 since its launch less than nine months ago.

Microsoft also announced that MGM and NBC Sports are using Silverlight for different forthcoming video efforts.

"NBC Sports has evaluated many different technologies for delivering high-quality experiences online, and none have delivered the video quality, scalability and business value that Microsoft Silverlight has consistently brought," said erkins Miller, senior vice president of Digital Media at NBC Sports. "As we look forward to the 2010 Olympic Winter Games in Vancouver as well as other major championships in 2010, we will be using Silverlight as the preferred technology to deliver the best in next-generation online high-definition video experiences."

Microsoft says it has over 300 partners in 30 countries helping customers design and develop with Silverlight and Expression. These include leading content delivery networks, solution providers, and independent software vendors.

"Silverlight and Expression fill a clear need in the marketplace for a complete end-to-end solution that makes it easy for development teams to work together effectively, from concept to deployment, to create the types of rich interactive experiences today's users expect," said Scott Guthrie, corporate vice president of the .NET Developer Platform at Microsoft.

New features with these releases of Silverlight and Expression include: 

- Expression SketchFlow. Available to customers just four months after its initial debut at MIX09, SketchFlow provides development teams unrivaled capabilities to rapidly prototype applications and take their ideas from concept to reality.

- Out of Browser. Silverlight 3 provides the seamless ability to add out-of-browser, connected and disconnected scenarios for cross-platform applications, radically improving the productivity and capabilities over traditional RIAs.

- IIS Smooth Streaming. As part of Internet Information Services 7.0 (IIS7) Media Services and combined with Silverlight 3, IIS Smooth Streaming enables the industry's first HDTV-quality (1080p) video experiences with rich interactivity for both on-demand and live video.

Silverlight 3 can be downloaded immediately. If you already use Silverlight, you should be automatcially upgraded. Expression 3 should be available in the next 30 days.
