First there was UNIX, circa 1972 Then the Timeline Split In 1977, for $90, Bob Fabry and others, compiled/built the first versions of BSD, short for Berkeley Systems Distribution. In 1991, Linus Torvalds posted in a Newsgroup, about software he used from Richard Stallman, who started GNU in 1983, and Linus'es UNIX was born. Apple reacquired NeXT Software in 1996, after Steve Jobs was fired from Apple in 1984, and used the software and people there to build OS X. OS X is the Darwin OS + the NeXT Desktop Environment. And now we're back to Bullet #1, as Darwin is a closed source fork of BSD. For the Open Source Project, see PureDarwin. For the Official Apple Developer Page, see Apple Open Source.
