HTML 5 is the next revision of the Hypertext Markup Language (HTML), the standard programming language for describing the contents and appearance of Web pages. HTML 5 was adopted by the new HTML working group of the World Wide Web Consortium (W3C) in 2007. This group published the first public draft of HTML 5 in January 2008, but refinements are expected to continue for several years before HTML 5 becomes a formal recommendation.
In theory, HTML 5 will allow the Web browser to become a development platform. A primary goal for HTML 5 is to ensure interoperability among browsers so that Web applications and documents behave the same way no matter which HTML 5-compliant browser is used to access them. (Older browsers that do not support HTML 5 will be able to ignore the new constructs and still produce legible Web page s.)
HTML 5 is expected to offer numerous improvements over HTML 4, including:
New parsing rules for enhanced flexibility
Elimination of outmoded or redundant attributes
Drag and drop
Back button management
Timed media playback
Detailed rules for parsing
MIME and protocol handler registration

HTML5 is the successor of HTML or HTML4. It overcome all the limitations of HTML.
The problem with HTML4 is its limited functionality. It must be extended through plugins, like Flash, to provide more than simple text and images. Many video players, for example, were created and maintained on the Flash platform and embedded into HTML pages. Many web apps were developed using Java and embedded as well. With all of these plugins, it becomes hard to maintain proper standards. It produce the new issue of browser compatibility.
Here comes our New HTML5. More specifically, HTML5 adds a whole bunch of new markup tags:
<header> and <footer> tags to help you isolate the tops and bottoms of content blocks. Can be used more than once on a single page.
<article> tag which identifies a specific, singular piece of content, e.g., a blog post or a user comment.
<nav> tag to specify which sections should be considered navigational blocks.
<section> tag that lets you define a generic section of content; similar to the currently existing <div> tag.
<audio> and <video> tags to mark the inclusion of audio or video content.
<canvas> tag that lets you draw graphics using a separate scripting language.
<embed> tag to embed external content or applications into the page.
HTML5 also deprecates some tags: <acronym>, <applet>, <font>, <frame>, <frameset>, <noframes>, and a handful of others.
The full standards specification for HTML5 is planned to be completed by 2014, but HTML5 has made lots of progress already and it can be used to implement site features even today. The full standards specification for HTML5.1 is planned to be completed by 2016.
