The Future of Silverlight

It's a fair question—and I'll provide a detailed answer—but I think it's predicated upon an oversimplification of the role of standards that I'd like to clear up first. I'd also like to delineate why premium media experiences and "apps" are better with Silverlight and reveal how Silverlight is going beyond the browser to the desktop and devices.

It's not commonly known, perhaps, that Microsoft is involved in over 400 standards engagements with over 150 standards-setting organizations worldwide. One of the standards we've been involved in for years is HTML and we remain committed to it and to web standards in general. It's not just idle talk, Microsoft has many investments based on or around HTML such as SharePoint, Internet Explorer, and ASP.NET. We believe HTML 5 will become ubiquitous just like HTML 4.01 is today.

But standards are only half of the story when we think of the advancement of our industry. Broadly-implemented standards are like paved roads. They help the industry move forward together. But before you can pave a road, someone needs to blaze a trail. This is innovation. Innovation and standards are symbiotic—innovations build on top of other standards so that they don't have to "reinvent the wheel" for each piece of the puzzle. They can focus on innovating on the specific problem that needs to be solved. Innovations complement or extend existing standards. Widely accepted innovations eventually become standards. The trails get paved.
