Since their debut in 2010, Humble Bundles and the Humble Store have put out a lot of sweet deals on games. They've also raised a big pile of money for charities. The company announced today that it has now raised more than $100 million for organizations around the world including Child's Play, the American Red Cross, the EFF, and Doctors Without Borders/Médecins Sans Frontières. 

The very first Humble Bundle—the Humble Indie Bundle—went live on May 4, 2010, with World of Goo, Aquaria, Gish, Penumbra: Overture, Lugara HD, and eventually Samorost 2, for as much (or as little) as people wanted to pay. I thought that was a monumentally bad idea—not the games, which are great, but the choose-your-own-price concept—but it ended up pulling in well over $1 million over the course of just a week, a big chunk of which went to EFF and Child's Play. The second Humble Indie Bundle came in December with Braid, Cortex Command, Machinarium, Osmos, and Revenge of the Titans, and approached $2 million in sales.
