The first Amiga computer model, the A1000, was released in 1985 by Commodore Inc.
The design team was headed up by Jay Miner and development of the system began in 1982 under the Amiga Corporation company. Commodore acquired Amiga Corporation in the summer of 1984, snatching the Amiga chipset from under the nose of Atari, who originally funded the project. Commodore filed for bankruptcy in 1994, despite the success of the A1200 and CD32.
The Amiga range was based on the Motorola 68000 chipset, but made use of proprietary graphics and sound co-processors (codenamed Denise and Paula respectively), which took the load off of the CPU and allowed the Amiga to process more than just gaming graphics extremely efficiently. The Amiga revolutionized video production, providing an affordable CG solution with the Newtek Video Toaster (which later evolved into the Newtek TriCaster, the core of Giant Bomb's video production). It was the first consumer grade computer to be able to sample and record stereo audio in 44.1khz (CD quality) at the time. Over the lifetime of the computer, three graphics and sound chipsets were used: OCS (Original ChipSet), ECS (Enhanced ChipSet) and AGA (Advanced Graphics Architecture).

is the native operating system for the Amiga family of home computers, earlier known as Workbench (the name Workbench was used as the name of the file manager in AmigaOS 3.1 and onwards). It is an multitasking capable system, using a workbench metaphor (rather than a desktop, as most current operating systems), where files and icons were stored in "drawers", which displayed a window with contents when they were pulled out. One unique feature with AmigaOS was it's ability to run software in windows using different color depths, palettes and resolutions in each, whereas Windows and MacOS at the time used a system wide color depth which could only be circumvented by full screen applications.
