I first missed this New York Times article from March 17, 2008 but I don't want you to miss it. The article focused on a new book by North Western University Professor Weisbrod focused on revenue generating by nonprofits. Three cases were cited in the article: the Metropolitan Museum of Art which generates more than $96 million dollars from revenue sources like parking facilities; the Girl Scouts whose uniforms sales represents 41% of annual budget; and Public Television which generated $4 billion from the sale of stocks for Tickle Me Elmo.

Professor Weisbrod's book sounds more critical than supportive particularly because of the issues around tax exemption. Anyway, this sounds like a good read for all those who are students of nonprofit social enterprise.
