Chase has launched a campaign on Facebook where you can vote on which 5 charities get $1 million. This is a great way for multiple charities to get exposure, even if they don't win the top prize. Besides getting the participants to interact, there is a viral effect of people sharing this campaign with their "friends" on Facebook either directlly of via posts to their status feeds.

I voted for PUSH America the philanthropy supported by my fraternity Pi Kappa Phi. I was invited via a Pi Kapp LinkedIn group- yet another nod to Social Marketing.
