BBC Magazines is the
magazine publishing division of the British
Broadcasting Corporation (BBC) and it seems that according to Dries Buytaert, BBC has used Drupal for a number of their online publishing sites:

• BBC Music Magazine
• BBC Countryfile
  Magazine
• BBC Focus Magazine
• BBC Who Do
  You Think You Are Magazine
• BBC History Magazine
• BBC Home And Antiques

Recently our agency here in Singapore has finished the first phase of a major publishing site for Expat Living. Work is underway to improve on the overall experience and feature list.

Drupal rocks!
