# The GNU system has turned thirty years old on September 27, 2013 In 1983, Richard Stallman launched the free software movement with the words, "Free Unix!" We've freed a lot more than that in the last thirty years. The GNU system is now a vast universe of fully free operating systems, window managers, andsoftware that serves almost every imaginable purpose. More than 95 percent of the world's supercomputers run free software. A majority of web servers run free software. Even more impressive, there are estimated to be tens of millions of free software users worldwide. That's a lot to celebrate. This weekend, the Free Software Foundation will be honoring thirty years of GNU with a [celebration and hackathon in Cambridge, MA][0]. Around the world, there are over [eighteen celebrations][1] planned on almost every inhabited continent. And online, people are showing their love for GNU by embedding the [special 30th anniversary badge][1] on their websites and [donating to support GNU's future work][2].
