We invited the team from "The Blink Tank":
http://theblinktank.com, a social venture founded to jumpstart business models for organizations in the social sector, to meet with a few of our grantees today. Of particular interest is "Mission Ad Works":
http://missionadworks.com/ which is their socially responsible web advertising services business. Structured much like other businesses such as "Federated Media":
http://federatedmedia.net/, Mission Ad Works has a socially responsible filter on both the advertiser as well as the media partner.
