Unity is an integrated authoring tool for creating 3D video games or other interactive content such as architectural visualizations or real-time 3D animations. Unity is similar to Director, Blender game engine, Virtools, Torque Game Builder or Gamestudio in the sense that an integrated graphical environment is the primary method of development. The editor runs on Windows and Mac OS X and can produce games for Windows, Mac, Linux (soon, currently in beta), Wii, iPad, iPhone, as well as the Android platform. It can also produce browser games that use the Unity web player plugin, supported on Mac and Windows. The web player is also used for deployment as Mac widgets. Support for Xbox 360 and PlayStation 3 have recently been added. Unity won the Wall Street Journal 2010 Technology Innovation Award in the software category. In 2009, Unity Technologies was named one of Gamasutra's "Top 5 Game Companies of 2009" for Unity.
