Over time, Unix fragmented, with various manufacturers and organizations publishing their own variants under license from AT&T. These were directly or indirectly derived from AT&T source code but generally did not use the Unix trademark. Important examples from the 1980s include [[BSD]], [[SunOS]] and [[Xenix]]. | Over time, Unix fragmented, with various manufacturers and organizations publishing their own variants under license from AT&T.
