In September 1983 Richard Stallman made the GNU project announcement. Stallman’s plan was to create a free alternative to the popular Unix operating system. GNU ( for GNU’S not unix) in addition to it being free of charge it was also going to allow users the freedom to share and change it. In 1985 Stallman created The Free software foundation based on his philosophy. Although GNU did not function properly as a fully operating system, it created the tools for another Unix type system called Linux. The operating system is known as GNU/Linux as the GNU project forms a large part of Linux.
