History
In 1987, AT&T Corporation and Sun announced that they were collaborating on a project to merge the most popular Unix variants on the market at that time: BSD, System V, and Xenix. This became Unix System V Release 4 (SVR4).
On September 4, 1991, Sun announced that it would replace its existing BSD-derived Unix, SunOS 4, with one based on SVR4. This was identified internally as SunOS 5, but a new marketing name was introduced at the same time: Solaris 2. While SunOS 4.1.x micro releases were retroactively named Solaris 1 by Sun, the Solaris name is almost exclusively used to refer to the SVR4-derived SunOS 5.0 and later.
The justification for this new "overbrand" was that it encompassed not only SunOS, but also the OpenWindows graphical user interface and Open Network Computing (ONC) functionality. The SunOS minor version is included in the Solaris release number; for example, Solaris 2.4 incorporated SunOS 5.4. After Solaris 2.6, Sun dropped the "2." from the number, so Solaris 7 incorporates SunOS 5.7, and the latest release SunOS 5.11 forms the core of Solaris 11.

Famous quotes containing the word history:
“There is a constant in the average American imagination and taste, for which the past must be preserved and celebrated in full-scale authentic copy; a philosophy of immortality as duplication. It dominates the relation with the self, with the past, not infrequently with the present, always with History and, even, with the European tradition.”
—Umberto Eco (b. 1932)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (1818–1883)
“The history of men’s opposition to women’s emancipation is more interesting perhaps than the story of that emancipation itself.”
—Virginia Woolf (1882–1941)
