employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian
Kernighan, Douglas McIlroy, and Joe Ossanna. The Unix operating system
was first developed in assembly language, but by 1973 had been almost
entirely recoded in C, greatly facilitating its further development and
porting to other hardware. Today's Unix systems are split into various
branches, developed over time by AT&T as well as various commercial
vendors and non-profit organizations. The second edition of Unix was

The Open Group, an industry standards consortium, owns the “UNIX” trademark. Only systems fully compliant with and certified according to the Single UNIX Specification are qualified to use the trademark; others might be called "Unix system-like" or "Unix-like" (though the Open Group disapproves of this term). However, the term "Unix" is often used informally to denote any operating system that closely resembles the trademarked system.
