Eight years after it was started by a 19-year-old college freshman as a blogging software, WordPress now powers 14.7 percent of the world’s top one million websites. It is used in 55 million websites.
In his annual State of The Word address last week, WordPress founder Matt Mullenweg also said the open source content management system (CMS) now runs 22 out of every 100 new websites created in the US.
The velocity in WordPress adoption and its dominance illustrate the strength of the open source model, where the community is involved in the development of the software. It is not a coincidence that the top open source CMS packages today, WordPress and Drupal, also have the most active developer and user communities.
