I was under the impression that OpenGL was more popular than DirectX. OpenGL is Used on all of the current generation consoles and handhelds, except Xbox, and several last generation consoles as well.
OpenGL is now supported on Vista by Microsoft, although OpenGL has always worked under windows, it was only supported by the GPU makers previously. OpenGL works for all Unix based Operating systems to include Mac and Linux. Both are used by major animation studios and graphical artists.
OpenGL also is used for many Windows games, including all ID and Blizzard made games, which are very popular.
