HTML
HyperText Markup Language (HTML) is a markup language consisting of a set of tags for marking up hypertext documents [1]. HTML is a W3C standard used for creating World Wide Web pages. HTML conforms to, and is a subset of, Standard Generalized Markup Language (SGML).
HTML resembles old-fashioned typesetting code, where a block of text is surrounded by tags that indicate how it should appear. HTML allows text to be linked to another file on the Internet, similar to Vannevar Bush's proposed Memory Extender (Memex).
Tim Berners-Lee created the original HTML (and many associated protocols such as HTTP) on a NeXTcube workstation using the NeXTSTEP development environment.

XHTML
HTML has been partially replaced by Extensible HyperText Markup Language (XHTML), which is a reformulation of HTML using Extensible Markup Language (XML). The current version of XHTML is [2], which was released in 2001.
