The SHARE Operating System (SOS) is an operating system introduced in 1959 by the SHARE user group. It is an improvement on the General Motors GM-NAA I/O operating system, the first operating system for the IBM 704. The main objective was to improve the sharing of programs.
A series of articles describing innovations in the system appears in the April 1959 Journal of the Association for Computing Machinery.
