The Atari Jaguar was released in 1993 and was marketed as the world's first 64-bit system. However, sales at launch were well below the incumbent fourth generation consoles, and a small games library rooted in a shortage of third party support made it impossible for the Jaguar to catch up, selling below 250,000 units. The system's 64-bit nature was also questioned by many. Its only add-on, the Jaguar CD, was released in 1995 and was produced in limited quantities due to the low install base of the system. The 32-bit Atari Panther, set to be released in 1991, was canceled due to unexpectedly rapid progress in developing the Jaguar.
