Free Knowledge Culture Calendar/December 24

The first “real” use of the typesetting system TeX was for a christmas present in 1978. It is perhaps the oldest surviving free software project, dating from before the PC and the computer mouse. Its markup language was an important influence for HTML, and its arrival in India catalyzed the formation of the local Free Software movement in the late 1980s. With its perfectionist concept, this cornerstone of digital typesetting software is still valued today in one form or another for its high quality output.
