On the topic of...

...Socially Proactive Businesses, here are a few more that I can think of:

Apolis Activism: A luxury clothing brand designed to inspire liberty and support development.

Invisible Children's Bracelet Campaign: Sure it's nonprofit, but it's a business nonetheless. Providing employment and training to displaced people, proceeds support education in northern Uganda.

Tom's Shoes: For every pair you buy, a pair is given to someone in a poor country.

Edun Clothing: Founded by Ali Hewson (Bono's wife) Edun has made a bold commitment to selling only those garment created completely in Africa, from "grower to sewer."

These companies are pushing forward the idea of the Socially Proactive Business. I'm sure you can think of others. Leave them in the comments.
