HTML History

Since the beginning of the web, there have been numerous adaptations of HTML:

Version Year
Tim Berners-Lee developed www 1989
Tim Berners-Lee developed HTML 1991
Dave Raggett drafted HTML+ 1993
HTML Working Group characterized HTML 2.0 1995
W3C Recommended HTML 3.2 1997
W3C Recommended HTML 4.01 1999
W3C Recommended XHTML 1.0 2000
HTML5 WHATWG First Public Draft 2008
HTML5 WHATWG Living Standard 2012
HTML5 W3C Final Recommendation 2014

Tim Berners-Lee developed the "World Wide Web" in 1989, and the Internet took off in the 1990s.

From 1991 to 1998, HTML created from adaptation 1 to rendition 4. 

In 2000, the World Wide Web Consortium (W3C) suggested XHTML 1.0. 

The XHTML linguistic structure was strict, and the engineers were compelled to compose substantial and "well-formed" code.

In 2004, WHATWG (Web Hypertext Application Technology Working Group) was framed in light of moderate W3C improvement, and W3C's choice to shut down the advancement of HTML, for XHTML.

WHATWG needed to create HTML, steady with how the web was utilized, while being in reverse good with more seasoned renditions of HTML.

In the period 2004-2006, the WHATWG activity picked up help by the major program vendors.

In 2006, W3C declared that they would bolster WHATWG.

In 2008, the first HTML5 open draft was released.

In 2012, WHATWG and W3C settled on a separation:

WHATWG will create HTML as a "Living Standard".

A expectation for everyday comforts is never completely total, yet dependably refreshed and improved. New highlights can be included, however old usefulness can not be removed.

W3C will build up a conclusive HTML5 and XHTML5 standard, as a "snapshot" of WHATWG.

The W3C HTML5 recommendation was discharged 28 October 2014.
