In 2001, SCO sold its rights to Unix to Caldera Systems, retaining its Tarantella product line, and changed its name to Tarantella, Inc. Caldera subsequently changed its name to The SCO Group, which has created some confusion between the two companies. The company described here is the original Santa Cruz Operation, called by some "old SCO" to distinguish it from "The SCO Group".
SCO was founded in 1979 by Doug Michels and his father Larry Michels as a UNIX porting and consulting company. In 1983 it shipped Xenix for the Intel processor, its first packaged UNIX System. Xenix, renamed SCO UNIX in 1989 following SCO's port to the Intel 80386 processor, became the most installed flavor of UNIX due to the popularity of the x86 architecture.
The company went public in 1993 on the Nasdaq Stock Exchange.
In 1995 SCO acquired the AT&TAT&T formerly an abbreviation for American Telephone and Telegraph Corporation is an American telecommunications company, publicly listed on the New York Stock Exchange under the ticker symbol T .

In modern programming languages, the source code which constitutes a software program is usually in several text files, but from Novell and eventually became the licensor for UNIX. SCO also acquired the UnixWare operating systemIn computing, an operating system OS is the system software responsible for the direct control and management of hardware and basic system operations, as well as running application software such as word processing programs and web browsers.

Events Y2K passes without the seri that it would sell its Server Software and Services Divisions, as well as UnixWare and OpenServer technologies, to Caldera Systems, Inc. The purchase was completed in May 2001. At that time Caldera changed its name to "Caldera International", and the remaining part of SCO, the Tarantella Division, changed its name to "Tarantella, Inc."
People in the tech community have generally not understood why SCO was successful, or why Caldera wanted to buy the UNIX products. This was due to 15,000 value-added resellers (VARs) around the world who provided solutions for customers. For example, a doctor's office may want a computer, some terminals, accounting and health management software. The value-added resellers would provide that. The cost of the operating system was negligible, and the VARs liked it quite high anyway since they would add a standard markup to each item sold (5% of $1500 is a lot more than 5% of $29.99). Caldera wanted SCO's VAR channel to push Linux through, banking on larger revenues. In the end, the once loyal channel realised they could do Linux directly themselves and didn't need to be tied to a corporation.
In August 2002 Caldera International renamed itself " The SCO Group" since the SCO UNIX products were still a strong source of revenue mainly due to the huge installation base dating back to the 1990s. It is this SCO Group, formerly known as Caldera, and not the former Santa Cruz Operation now known as Tarantella, that sued IBM in 2003 for $1 billion for allegedly "devaluing" Unix by contributing to the Unix-like Linux operating system.
