As of the end of March 2012, version 3.3 had been downloaded over 12.2 million times.<ref>{{cite web |url=http://wordpress.org/download/counter/ |title=WordPress Download Counter |publisher=WordPress.org |accessdate=29 March 2012}}</ref>

| ==Product history==
| |
| | |
| ''b2/cafelog'', more commonly known as simply ''b2'' or ''cafelog'', was the precursor to WordPress.<ref>{{cite video |people=Andrew Warner, Matt Mullenweg |date=10 September 2009 |title=The Biography Of WordPress – With Matt Mullenweg |url=http://mixergy.com/the-biography-of-wordpress-with-matt-mullenweg/ |medium=Podcast |publisher=Mixergy |accessdate=29 March 2012 |time=10:57 |quote=b2 had actually, through a series of circumstances, essentially become abandoned.}}</ref> 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.<ref>{{cite web |url=http://codex.wordpress.org/History |title=History - WordPress Codex |accessdate=29 March 2012 |publisher=WordPress.org}}</ref> The name ''WordPress'' was suggested by Christine Selleck Tremoulet, a friend of Mullenweg.<ref>{{cite web |url=http://www.bigpinkcookie.com/2008/01/24/the-importance-of-being-matt/ |title=The Importance of Being Matt… |author=Tremoulet, Christine Selleck |publisher=Christine Selleck Tremoulet |date=24 January 2008 |accessdate=29 March 2012}}</ref>

| 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.<ref>{{cite web |url=http://www.salon.com/2004/08/09/six_apart/ |title=Blogging grows up |author=Manjoo, Farhad |publisher=Salon |date=9 August 2004 |accessdate=29 March 2012}}</ref><ref>{{cite web |archiveurl=http://web.archive.org/web/20060410125402/http://diveintomark.org/archives/2004/05/14/freedom-0 |url=http://diveintomark.org/archives/2004/05/14/freedom-0 |title=Freedom 0 |author=Pilgrim, Mark |publisher=Mark Pilgrim |archivedate=10 April 2006 |date=14 May 2004 |accessdate=29 March 2012}}</ref> 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.<ref>{{cite web |url=http://www.cmswire.com/downloads/cms-market-share/ |title=Open Source CMS Market Share Report 2009 |author=Water & Stone |publisher=CMS Wire |page=57 |date=17 December 2009 |accessdate=29 March 2012}}</ref>
