We shipped Silverlight 2 last month. Over the last 4 weeks, the final release of Silverlight 2 has been downloaded and installed on more than 100 million consumer machines. It has also recently been published to corporate administrators via the Microsoft SMS and Microsoft Update programs to enable them to automatically deploy across enterprises. Over 1 in 4 computers on the Internet now have some version of Silverlight installed.
Silverlight 2 was a major release, and delivered an impressive set of cross-browser, cross-platform functionality for Media and Rich Internet Application experiences. It has been great watching new sites launch using it.
