Silicon Graphics Inc. (SGI), the company that created OpenGL, has gone out of business. Before Direct3D and DirectX, there was OpenGL. If you were playing PC games in the 90's you'll undoubtedly hold fond memories of your first graphics accelerator and the beauty of Quake in OpenGL. To be fair, it looked good in Direct3D as well.
Nowadays, OpenGL makes its appearance on Macs and almost every other non-Windows platform. Thankfully, OpenGL will be fine as it is managed by a different company: the Khronos Group, which took control of OpenGL on September 21, 2006.
The rest of SGI's assets will be sold to Rackable Systems for $25 million. This includes the supercomputers used to render the effects in Jurassic Park. Recent advances in visual effects that have made development more affordable had put SGI in a bad position.
