Video and History support in HTML5 with Internet Explorer 10 - Article on MSDN
Who hasn’t started looking at the mobile Web and HTML5—features like the viewport, new HTML5 controls, geolocation and many others that are part of smartphones, tablets and advanced browsers? With these features, developers have started to provide users with fairly common, new input controls; jQuery Mobile features; location and mapping; and much more. In this article, I describe two features that you might not be familiar with: the <video> tag and Web history. The <video> tag lets you display video without the need for plug-ins like Flash. Web history allows users to use the Back button to return to the previous page in an AJAX application.
