History of HTML
HTML was developed by Tim Berners-Lee in 1991. He proposed this method of hyperlinking, linking between documents, and wrote the code specification and created the first browser software for it. He adapted Standard Generalized Markup Language (SGML) to create HTML. Since then many new additions of code have been developed;, HTML 2 (1995), HTML 3 (1997) etc all of which added more features.
XHTML is another version where the code needs to be exact. It is important to close every tag and to have <br/> at the end of every line.
The internet is “controlled” by W3C. the World Wide Web Consortium, at MIT in the USA. They set the standards that the internet responds to so that everyone can access all of its information and files. They set the standards for every file type on the internet now including audio and video.
