I'll be damned.

Originally sponsored by the U.S. Naval Research Laboratory[8] (which had been instrumental in the early development of onion routing under the aegis of DARPA), Tor was financially supported by the Electronic Frontier Foundation from 2004 to 2005.[10] Tor software is now developed by the Tor Project, which has been a 501(c)(3) research-education nonprofit organization [11] based in the United States of America [1] since December 2006. It has a diverse base of financial support;[10] the U.S. State Department, the Broadcasting Board of Governors, and the National Science Foundation are major contributors.[12] As of 2012, 80% of the Tor Project's $2M annual budget comes from the United States government, with the Swedish government and other organizations providing the rest,[13] including NGOs and thousands of individual sponsors.[14]

That's very interesting, I haven't played with Tor in a long time but I never got the impression it even needed a lot of funding. I just kind of thought it was more of a grassroots open source project.
