In 1999 HTML 4.01 was created. This subversion of HTML4 was published in and offered everything HTML4 did with three variations. XHTML is considered a different language that branched from HTML 4.01 that started as XML 1.0 then developed. XHTML 1.0 was published in 2000 then republished in 2002. Recently, HTML5 was published in 2008 by W3C. HTML5 has the same basic structure as previous versions of HTML's, but has many new features that are admired by its users. Every bit of information came from Designing with Web Standards, Third Edition by Jeffrey Zeldman and Ethan Marcotte.
