...Hi, I'm Dave Fester, general manager for the Windows Digital Media Division at Microsoft. We've been hard at work on our next generation of Windows media platform, code name CORONA that we previewed last December. We believe that Windows Media Corona will dramatically enhance the digital media experience for consumers, entreprises and counter-providers.
In fact, it will offer a new platform for new innovations on the internet and beyond.
