The AmigaOS has been characterized as “the best operating system ever developed”.
The "Amiga Operating System" originally targeted the desktop computing market. It was built around tightly integrated hardware and software. The hardware was originally based on proprietary chips running the Motorola 68000 series of processors. The AmigaOS was designed from its inception as a true multi-threaded, multi-tasking, multi-media operating system. This combination of hardware and software produced a very fast, powerful and easy to use computing platform. Over 6 million Amiga computers were sold.
The Amiga platform was readily adopted by the television, motion picture and video game development communities.
This system was the enabler for the birth of Newtek's Video Toaster -- the first real-time video editing system. AmigaOS was also the first commercially available operating system to implement pre-emptive multitasking.
Over the years the computing industry moved from proprietary hardware to pluggable components. Stability and security became critical concerns for all operating systems. Support for 3D and easy access to and through the Internet drove development. Amiga responded to these market changes by releasing OS 3.1, 3.5 and 3.9.
In 2001, Amiga, Inc. entered into a license for the development of AmigaOS 4.0 with AmigaOne™ Partners, collectively Hyperion VOF and Eyetech Group Ltd. The license agreement was terminated on December 20, 2006.
