Can playing Facebook games change the world?

>> about 300 million people play facebook games every month. with such a huge audience, the pulitzer prize winning author of " half the sky movement" turns it into a facebook game, to empower women and girls around the world . she is here to tell us about it. cheryl, great to see you.

>> great to see you. thanks for having me here.

>> explain half the sky movement. what is the message?

>> it started out with a book that my husband and i wrote about women and girls in the developing world . we really just wanted to lay out the issues and also talk about some of the wonderful, amazing people who have come up with solutions. and it's actually kind of triggered a movement.

>> it has.

>> and now a game on top of that, which will actually help to then, i guess, raise funds for the movement as well.

>> absolutely. for a number of partners who are in the game as well. i mean, it's probably the most ambitious, biggest social impact game ever. it's kind of like a farmville for social change , if you will, on facebook .

>> how does the game generate money for these organizations?

>> what happens is that it follows a fictional woman called radika, who lives in a fictional village in india. she goes on these various quests for a lot of obstacles thrown her way. your challenge is to actually help her navigate those quests and move her along her journey. and on the way, there are a number of causes and partners that are mapped through the quest and can be supported by money. it's never been done before this way.

>> you can give as little or as much as you want along the way.

>> you can give as little as a dollar and as much as you want.

>> fantastic when you think 300 million people will be playing this. i imagine the idea is really to raise awareness as well, not just the money.

>> oh, totally. that is the primary point, because -- look, we did a point. we know book reading is not america's favorite past time. we did a documentary. you have to sit there for four hours. a game, you can spend ten minutes and maybe learn something.

>> very cool. congratulations. the game debuts, as we said, on facebook today. an awful lot
