id Softwareはいつ設立された
id Software is an American video game developer based in Dallas, Texas. It was founded in February 1991 by four members of the software company Softdisk: programmers John Carmack and John Romero, game designer Tom Hall, and artist Adrian Carmack. The founders, along with business manager Jay Wilbur, had previously developed the 1990 personal computer game "Commander Keen in Invasion of the Vorticons" as "Ideas from the Deep" while still employees of Softdisk. After its founding, id developed further shareware computer games in the "Commander Keen" series for Apogee Software, as well as a series of small games for Softdisk, before releasing the "grandfather of first-person shooters", "Wolfenstein 3D", in 1992 through both shareware and retail. It was followed by "Doom" (1993), considered one of the most significant and influential titles in video game history, which id self-published in shareware before releasing for retail through GT Interactive. GT Interactive published a sequel, "Doom II" (1994) and the two companies split publishing duties on id's final self-published or shareware game, "Quake" (1996).
