Open Group

History

In January 1997, the responsibility for the X Window System was transferred to The Open Group from the defunct X Consortium. In 1999, X.Org was formed to manage the X Window System, with management services provided by The Open Group. The X.Org members made a number of releases up to and including X11R6.8 while The Open Group provided management services. In 2004, X.Org and The Open Group worked together to establish the newly formed X.Org Foundation which then took control of the x.org domain name, and the stewardship of the X Window System.
