… among many great new features, it allows to view video and play music natively without additional plugins ...
HTML5 has been designed to deliver almost everything you'd want to do online without requiring additional software such as browser plugins (i.e. Flash for viewing videos). It does everything from animation to apps, music to movies, and can also be used to build incredibly complicated applications that run in your browser.
HTML5 isn't proprietary, so you don't need to pay royalties to use it. HTML5 does not belong to a company or a specific browser. It has been forged by The Web Hypertext Application Technology Working Group (WHATWG), a growing community of people interested in evolving the Web, and a consortium of technological leaders that includes The World Wide Web Consortium (W3C), Google, Apple, Mozilla, Facebook, IBM, Microsoft, HP, Adobe, and many others. HTML5 is also cross-platform, which means it doesn't care whether you're using a tablet or a smartphone, a netbook, notebook or ultrabook or a Smart TV: if your browser supports HTML5, it should work flawlessly.
All modern browser support HTML5: Firefox, Safari, Chrome, Opera, and Internet Explorer.
