Websites that use Drupal

There are quite a few big web companies using Drupal to power their websites.

I am a big fan of Drupal, and use it for many of my websites. It is a very powerful and flexible CMS portal system. I know it is capable of powering big websites. I always like hearing of big web companies using Drupal, and below I have listed any I have found. I have also listed other Drupal powered websites that I like.
