'''HyperText Markup Language''' ('''HTML''') is a [[markup language]] and is the [[World Wide Web Consortium|W3C]] standard used for creating [[World Wide Web]] pages.  HTML conforms to, and is a subset of, Standard Generalized Markup Language ([[SGML]]).  [[Web browser]] programs such as [[Internet Explorer]], [[Firefox]], [[Opera]] or [[Safari]] consume HTML documents by interpreting their marked-up contents and then displaying them, according to the markup rules, for people to read. 
#REDIRECT[[HTML]]
 
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 [[Memex|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.
 
==Tags==
Like most markup languages, HTML uses tags to convey information.
 
==Current Version==
The HTML standard is maintained by the [[World Wide Web Consortium]] (commonly shortened to [http://www.w3.org W3C]).  The current official version of HTML is [http://www.w3.org/TR/html401/ 4.01] which was ratified in December [[1999]].  4.01 is a [[version numbering|minor step]] from 1997's 4.0 standard.
 
==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 [http://www.w3.org/TR/xhtml11/], which was released in [[2001]].
