IBM Hursley

Established in Hursley House, an 18th-century Queen Anne style mansion in 1958, the facility has been instrumental in the development of IBM's software technologies since the 1950s.

Among the software developed by IBM Hursley is the Customer Information Control System (CICS), used in ATMs, which was the first Hursley product with a billion dollars in annual revenue.

In 1963 it purchased 100 acres (405,000 m2) of land surrounding the house and has since erected a large modern office complex employing over 1500 people.

The facility is host to the IBM Client Centre, which offers potential clients a secure environment where they can test company software and work with staff experts on best practices, proof of concept, and proof of technology.
