Unix is a multitasking, multi-user operating system originally developed in AT&T's Bell Labs in 1969. As Bell Labs gradually withdrew its support from the Multics project, Bell Labs members of the Multics project began to develop a smaller scale operating system, initially without Bell Labs financial support. Originally intended as a platform for programming, Unix grew in capability as users added and shared their own programs. Because AT&T provided the Unix operating system for free, and because it ran on a wide variety of hardware, including low-end machines, it became popular in government and academic institutions. This resulted in a large community of users and programmers contributing to the software and community support available for the OS. Since the 1980s, Unix has split into multiple branches of development, including commercial varients, such as Solaris and HP-UX, university-developed variants, such as UC Berkeley's popular BSD, and the Unix-like variants, such as MINIX and Linux.
