The Free Software Foundation, which launched the GNU General Public License, was founded by Richard Stallman, and the fee software movement, which started when he launched the GNU Project on 27 September 1983, began in earnest.
It took less than 15 years from the start of the movement, to the dismay of companies like IBM and Microsoft, for many open source projects, including Linux (1991), Apache (1995), MySQL (1995), and PHP (1995), to dominate the web.
And allow LOLCats everywhere to dominate the web. 😉
