Celebrating 25 Years of Linux

On August 25, 25 years ago, Linus Torvalds wrote a post on Usenet announcing he was “doing a (free) operating system.” He was asking for feedback and suggestions for features, making it clear that the project was “just a hobby.”

Jump to 2016 and Linux is driving real innovation in some of the world’s largest and most successful enterprises, including Google, Amazon and Facebook. It is one of only two operating systems (OS) still growing and, with Windows set to grow by just 1.9%, Linux is in a league of its own at 13.4% compound annual growth rate (CAGR).

So how did Linux go from “just a hobby” to the fastest growing operating system in the world? And more importantly—where will it go from here?

Take a look at some of the fun things we’ve been putting together to celebrate 25 years of Linux.

Happy Birthday Linux!



For over five years, we’ve been hard at work to make Linux a reality on Microsoft platforms. We are grateful to the community for welcoming us and letting us be part of this 25-year-old journey—with more to come. Happy b-day to Linux from all of us here in Redmond!

SGI is happy to celebrate the 25th anniversary of Linux with the Open Source community. I vividly remember when SGI made the bold decision early on to shift from proprietary operating systems to Linux, and to begin contributing changes to open source. It was a risky move at the time! Since then, SGI has had a significant impact on open source, including the XFS file system and general OS scalability. The community benefits from this daily, and in turn SGI benefits from a mature community-led operating system for high performance computers, such as the SUSE Linux Enterprise Server, which today is at the heart of both our scale up SGI UV large memory systems and our scale out SGI ICE and Rackable systems. We are excited for many more years of community innovation with Linux!
