Who made html 5?

Question

Tell his nmame and year.

Answer 1

I found this on a web page:
https://www.keycdn.com/blog/html-vs-html5
HTML5 is the result of a collaboration between the World Wide Web Consortium, or W3C, and the Web Hypertext Application Technology Working Group, or WHATWG. The organizations teamed up in 2006 to reduce reliance on plugins, improve error handling and replace scripting with more markups. Consequently, HTML5 has greatly simplified the process of creating web applications.
