HTML5 was a major step in moving the Web forward.
HTML4 was published in December 1999 and HTML5 became a recommendation in October 2014.
That's 15 years ... centuries for the Web!!
The interest and enthusiasm from the community was amazing.
In the development of HTML5, we had several steps to move it forward.
One of those was getting a wide review from the community on the document and provide feedback.
We received around 1600 comments in 14 months, from May 2011 to August 2012, beating all previous records in reviews of W3C specifications.
Almost all of them were resolved by the editors and 40% of those resulted in changes in the specification.
Only 20 comments where controversial and difficult to resolve.
Additionally, the effort on testing the HTML5 functionalities was tremendous, thanks to the Test the Web Forward movement and the open source community.
We ran around 100,000 tests on HTML5 implementations as a result.
While the test suite was not certainly thorough, it was and still remain the highest number of tests for a single Web specification.
The Web was successful in bringing individuals from all around the world together. It's not owned by anyone but by everyone.
I'm looking forward to see what we're all going to come up with in the upcoming future.
