In the 1960’s IBM’s System/360 machines had no interactive capabilities to start although customers, especially public utilities, clamored for one.  Ben Riggins, known as the father of CICS, was sent to an IBM development facility near Chicago to make one.  The result was the Public Utility Customer Information Control System.  The name was later shortened to the Customer Information Control System, now known as CICS. In 1969, IBM unbundled software from hardware and began to sell CICS on its own.
In 1971, IBM began to sell CICS for its smaller operating systems, DOS for small mainframes and the simpler DOSE, the entry version of DOS.
In 1973, the development of CICS moved from the Chicago area to Hursley, England, where it is today.
A CMS version was marketed in 1985 as a single user development environment. A production VM version was introduced in 1987.
During the 1990’s, CICS continued its movement to other operating platforms such as the AS/400 and web environments.
