In 1985, Richard Stallman, one of the most brilliant minds in computer science, founded the Free Software Foundation and launched the concept of 'copyleft', the opposite of copyright. The aim, outlined in the GNU Manifesto (http://www.gnu.org/gnu/manifesto.html, [ 1 Stallman R. The GNU Manifesto. Dr Dobb's J. 1985; 10: 30 Google Scholar ]), was to make software programs 'free' as in 'freedom'.
