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: [[Berkeley Software Distribution]] (BSD), [[UNIX System V]], and [[Xenix]]. This became Unix [[System V Release 4]] (SVR4).<ref name="Salus">{{cite book

On September 4, 1991, Sun announced that it would replace 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''.<ref>{{cite press release

  }}</ref> 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.

Although SunOS 4.1.''x'' micro releases were [[retronym|retroactively named]] ''Solaris 1'' by Sun, the Solaris name is used almost exclusively to refer only to the releases based on SVR4-derived SunOS 5.0 and later.<ref>{{cite web

For example, Solaris 2.4 incorporates SunOS 5.4. After Solaris 2.6, the ''2.'' was dropped from the release name, so Solaris 7 incorporates SunOS 5.7, and the latest release SunOS 5.11 forms the core of Solaris 11.4.[[File:Solaris OS logo.svg|thumb|Solaris logo introduced with Solaris 10 and used until Oracle's acquisition of Sun]]Although SunSoft stated in its initial Solaris 2 press release their intent to eventually support both SPARC and x86 systems, the first two Solaris 2 releases, 2.0 and 2.1, were SPARC-only. An x86 version of Solaris 2.1 was released in June 1993, about 6 months after the SPARC version, as a [[Desktop computer|desktop]] and uniprocessor workgroup server operating system. It included the [[Wabi (software)|Wabi]] emulator to support Windows applications.<ref>{{cite news |first1=Noel-Marie |last1=Taylor |first2=Mark |last2=Wallace |title=Solaris 2.1: The Rise of a New Sun? |newspaper=PC Magazine |date=June 15, 1993 |pages=243–244 |url=https://books.google.com/books?id=jMKfH6i9OcYC&pg=PA244}}</ref> At the time, Sun also offered the [[Interactive Unix]] system that it had acquired from [[Interactive Systems Corporation]].<ref>{{cite news |first=Steven J. |last=Vaughan-Nichols |title=Interactive Unix |newspaper=PC Magazine |date=June 15, 1993 |page=240 |url=https://books.google.com/books?id=jMKfH6i9OcYC&pg=PA240}}</ref> In 1994, Sun released Solaris 2.4, supporting both SPARC and x86 systems from a unified source code base.

On September 2, 2017, [[Simon Phipps (programmer)|Simon Phipps]], a former Sun Microsystems employee not hired by Oracle in the acquisition, reported on [[Twitter]] that Oracle had laid off the Solaris core development staff, which many interpreted as sign that Oracle no longer intended to support future development of the platform.<ref>{{Cite web |url=https://www.itwire.com/opinion-and-analysis-sp-481/open-sauce/79738-bye,-bye-solaris,-it-was-a-nice-ride-while-it-lasted.html|title=Bye, bye Solaris, it was a nice ride while it lasted|last=Varghese|first=Sam|website=ITWire|language=en-gb|access-date=2017-09-04}}</ref> While Oracle did have a large layoff of Solaris development engineering staff, development continued and Solaris 11.4 was released in 2018.<ref>{{Cite news|url=https://blogs.oracle.com/solaris/continuous-delivery,-really|title=Continuous Delivery, Really?|last=Lynn|first=Scott|access-date=2018-01-23|archive-date=January 23, 2020|archive-url=https://web.archive.org/web/20200123163819/https://blogs.oracle.com/solaris/continuous-delivery,-really|url-status=live}}</ref><ref>{{Cite news|url=https://blogs.oracle.com/solaris/2017-in-review-and-looking-ahead-to-2018|title=2017 in Review and Looking ahead to 2018|last=Lynn|first=Scott|access-date=2018-01-23|archive-date=January 23, 2020|archive-url=https://web.archive.org/web/20200123170913/https://blogs.oracle.com/solaris/2017-in-review-and-looking-ahead-to-2018|url-status=live}}</ref>
