WordPress is a free open-source blogging tool and content management system (CMS) based on PHP and MySQL. It has many features including a plug-in architecture and a template system. WordPress is used by over 14.7% of Alexa Internet's "top 1 million" websites and as of August 2011 manages 22% of all new websites.[3] WordPress is currently the most popular CMS in use on the Internet.[4][5]

It was first released on May 27, 2003, by Matt Mullenweg[1] as a fork of b2/cafelog. As of the end of March 2012, version 3.3 had been downloaded over 12.2 million times.[6]

Product history

b2/cafelog, more commonly known as simply b2 or cafelog, was the precursor to WordPress.[7] b2/cafelog was estimated to have been employed on approximately 2,000 blogs as of May 2003. It was written in PHP for use with MySQL by Michel Valdrighi, who is now a contributing developer to WordPress. Although WordPress is the official successor, another project, b2evolution, is also in active development.

WordPress first appeared in 2003 as a joint effort between Matt Mullenweg and Mike Little to create a fork of b2.[8] The name WordPress was suggested by Christine Selleck Tremoulet, a friend of Mullenweg.[9]

In 2004 the licensing terms for the competing Movable Type package were changed by Six Apart, and many of its most influential users migrated to WordPress.[10][11] By October 2009, the Open Source CMS Market Share Report reached the conclusion that WordPress enjoyed the greatest brand strength of any open source content management system.[12]

Most WordPress releases are codenamed after well-known jazz musicians, starting after version 1.0.[13]
