The versions leading to v7 are also sometimes called Ancient UNIX. After the release of Version 10, the Unix research team at Bell Labs turned its focus to Plan 9 from Bell Labs, a distinct operating system that was first released to the public in 1993. All versions of BSD from its inception up to History of the Berkeley Software Distribution#4.3BSD|4.3BSD-Reno are based on Research Unix, with versions starting with History of the Berkeley Software Distribution#4.4BSD and descendants|4.4 BSD and History of the Berkeley Software Distribution#Net/2 and legal troubles|Net/2 instead becoming Unix-like.
