HTML 5 Timeline2004 – Workshop on web Applications and Compound Documents

2005 – Web Applications 1.0 Working Draft published

2007 – W3c adopt WHATWG’s work in a new charter, publishes the new HTML 5 Working Draft

2009 – Last call issued for the HTML 5 Working Draft

2012 – HTML 5 Specification to reach Candidate status (projected)

2022 – HTML 5 Specification to reach Recommendation status (projected)

Current State of HTML 5

2010 - 2011 Working Draft is in Last Call

Some parts of the Draft are more mature than others.

Increasing number of devices and browsers feature partial implementation.

You don’t have to wait to start using some aspects of HTML 5!

Downsides

Development of HTML5 specifications is slow and is subject to change

Real time video streaming is not supported nor is the full screen video

HTML is not an XML standard, so may be incompatible with XSLT & MathML

FutureEven though it is far from being finished, a lot of developers have

started use HTML5 features that are being currently supported by the browsers.

It will eventually evolve into a programming platform.

There is a possibility that it will replace Flash & Silverlight.

Search Engines will give better results.

Web Pages will be able to load faster.

Any Doubts …??

Thank You
