Zappos has been using Drupal for over 3 years. We have utilized Drupal for homepages, landing pages, brand pages, various static content driven websites (blogs.zappos.com, developer.zappos.com), and many other uses.
Topics we will be covering in this case study include:

• How we got started with Drupal and a brief evolution
• How Drupal fits into our ecommerce platform
• How we are using the system today, e.g. integrating into our websites, customer interface, and development environment and deployment
• Touch upon other uses outside of our ecommerce platform
