Microsoft has hinted that they are moving from their own Silverlight to HTML5 for web applications. Silverlight is Microsoft’s alternative to Flash, and will remain the top developer tool for Windows Phone 7. Netflix streaming runs on Silverlight, so it does have some major support, but just not widespread on the general Internet yet.
When Microsoft first showed off Internet Explorer 9, its most HTML 5 compliant version of IE to date, in March of this year, questions began to arise about the company’s commitment to Silverlight. Officials insisted that the two would coexist and that Silverlight would be Microsoft’s cross-platform development platform for mobile, Web and PC platforms for a number of years to come, as HTML 5 was far from becoming an accepted standard.
