Originally developed by Dries Buytaert as a Message Board to chat with his friends at the University of Antwerp, Drupal became an Open Source Platform in 2001 and slowly evolved from drop.org into a Content Management Framework that is used as a back-end platform for approximately 2.2% of all websites from Personal Blogs to Corporate, Political, and Government Sites.
The name Drupal derives from an English rendering of the Dutch word "druppel" which means "drop"; the logo was developed by community member Steven Wittens incorporating a droplet.
The core contains features common to Content Management Systems including User Account Registration, Menu Management, RSS Feeds, Taxonomy (a Classification System), Page Layout Customization, and System Administration.
The Drupal Core Installation serves as one size fits all i.e. from a Simple Website, Blog, Internet Forum, or Community Platform providing User Generated Content; although Drupal is considered to be to most complicated CMS to manage, it is the most technically advanced and enjoys popularity among seasoned web developers.
Drupal received significant attention in 2003 after building a customized Drupal-based project called DeanSpace for Howard Dean who was one of the candidates in the U.S. 2004 Presidential Election and over the years Drupal made significant improvements; by 2008 had reached 1.4 million downloads winning many awards such as Open Source CMS Awards and the Webware 100 three times in a row.
Some of the high profile companies that use Drupal include London Gatwick Airport, General Electric, Pfizer, University of Minnesota, Linux, The Economist, Weather.com, Georgetown University to mention but a few.
