Solaris is an operating system created by Sun Microsystems in 1992. It was created to run on their workstations (but it can be used on most modern PCs) and is still developed today. It used to be called SunOS until it was renamed to Solaris in 1992. As of 2010, it is one of the main commercial UNIX variants (The others are HP-UX, AIX, and z/OS). Solaris is ultimately based on UNIX System V. With version 10, released in 2009, most parts of it were made Open Source, and released as OpenSolaris. Solaris 10 runs on SPARC processors, as well as the 32-bit and 64-bit Intel and AMD processors. Oracle Corporation acquired Sun Microsystems in January 2010. Oracle continued developing Solaris, but it stopped developing OpenSolaris. OpenSolaris was later forked into the illumos kernel and the OpenIndiana distribution.

- Operating System Market Share, November 2012, courtesy of Net Applications, a marketing company which obtains its data from the Alexa Toolbar or related products. Because people who install these products on their computers are not always aware that the product reports web browsing habits back to the marketers at Alexa some security software considers the Alexa Toolbar spyware and removes it. Both the automated removal-as-spyware and the self-selecting nature of those who install software that reports on personal web browsing habits raises questions as to whether the resulting data represents a unbiased statistical sample of Internet users.
