1984: Launch of GNU
In the fall of 1983 Richard Stallman, a veteran of MIT's AI Lab who was unhappy with the increasingly closed nature of software source code, announced the GNU project. His goal was to build a clone of Unix using only code that could be freely shared and would always be publicly available. Many parts of the GNU operating system, which Stallman began building in early 1984, remain central to the free and open source software ecosystem today.
