Like so many transformative innovations, the creation of UNIX was the unintentional outcome of a failed experiment—specifically with a time-sharing operating system called Multics for the GE-645 mainframe. While it was originally developed as a side project with limited resources, UNIX has had a long influence on the systems many professionals work with today, even in environments where it wasn’t the original foundation.

According to one of UNIX’s creators, what they wanted to preserve with UNIX “was not just a good environment in which to do programming, but a system around which a fellowship could form. We knew from experience that the essence of communal computing, as supplied by remote-access, time-shared machines, is not just to type programs into a terminal instead of a keypunch, but to encourage close communication.”
