Doom (1993 video game)
Doom (typeset as DOOM in official documents and stylized as DooM in other media) is a 1993 first-person shooter (FPS) video game by id Software. It is considered one of the most significant and influential titles in video game history, for having helped to pioneer the now-ubiquitous first-person shooter.

The Ultimate Doom, an updated release of the original game featuring a fourth episode, was released in 1995 and sold at retail.

The popularity of "Doom" led to the development of an expanded version, "The Ultimate Doom" (1995), which includes a fourth episode. Additionally, numerous ports of the game have been released by other companies. An unofficial port of "Doom" to Linux was released by id programmer Dave Taylor in 1994; it was hosted by id but not supported or made official. Official ports of "Doom" were released for AmigaOS in 1993, 32X, Atari Jaguar, and Mac OS in 1994, Super Nintendo Entertainment System, PlayStation, and Windows in 1995, 3DO in 1996, Sega Saturn in 1997, Game Boy Advance in 2001, Xbox 360 in 2006, iOS in 2009, and PlayStation 3 in 2012. Some of these were bestsellers even many years after the initial release. "Doom" has additionally been ported unofficially to numerous platforms; so many ports exist, including esotera such as smart thermostats and oscilloscopes, that variations on "It runs "Doom"" or "Can it run "Doom"?" are long-running phrases.
