From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Microsoft contributes to Linux and other open source projects in many ways, including financially. The cynical among us believe it's for the same reason Google contributes to Mozilla. Legally it's harder to prove you're an evil monopoly if you financially support your competition. Microsoft's involvement in Linux only became noteworthy after their 2001 Antitrust suit.
