TUG is the oldest TeX-related organization, founded in 1980. We are membership-based and -funded, with about 1500 members at present. We provide infrastructure for TeX education, documentation, accepting donations and getting grants, and of course software development (http://tug.org/texcollection). We have published a print journal since our founding (http://tug.org/TUGboat) and a companion online-only journal for the last few years (http://tug.org/pracjourn).
