The Craigslist founder has been on a giving spree in recent years, with a significant portion of his grant making going to journalism. Through his Craig Newmark Philanthropies, an umbrella group for his foundations, he gave $20 million last year to create the Markup, a nonprofit news organization that aims to investigate the societal impact of new technologies. He contributed another $20 million to endow City University of New York’s newly named Craig Newmark Graduate School of Journalism, among other journalism grants. He also regularly backs groups that help veterans and their families, efforts to increase the number of women in technology fields, and voter-protection programs.
