Drupal is powering the Ubuntu ( http:www.ubuntu.com) website now. Matt Nuzum has a bunch of info about the decision to use Drupal and the implementation. Here is one quote though:

 "The decision was difficult. We finally chose Drupal. They have excellent documentation, the cms is easy to extend through modules, they have a responsive security team and it’s easy to learn to edit and add content."

After 8 months of development we are ready to release Drupal 5.0 to the world. Today is also Drupal's 6th birthday, so the timing could not be more perfect. Drupal 4.0 was released in 2002 and finally we feel confident to increase the major version number from 4 to 5.

Drupal powers sites across the web, ranging from the personal weblog of Tim Berners-Lee, podcast sites like TWIT.tv, community driven sites like SpreadFireFox.com, artist communities like Terminus 1525 to large media sites like TheOnion.com, MTV and even sites for NASA.
