id Software is an American video game company that is based in Texas. The company was founded in 1991 by four former employees at computer company Softdisk. John Carmack, John Romero, Tom Hall, and Adrian Carmack founded id Software in 1991. ZeniMax Media acquired id Software in June 2009. The company’s history is now available as a YouTube documentary. Check out the two videos below:

John Carmack is the man behind Commander Keen, Wolfenstein 3D, Doom, and Quake. He as the lead programmer behind the games and is the co-founder of id Software. Carmack has confirmed that Doom Classic has been submitted to Apple for approval in an interview with TouchArcade.

Doom Classic will be running on the OpenGL rendered graphics engine. The sound engine will have better quality and a crafted control system. It’d be cool if the modded versions of Wolfenstein 3D make it on the App Store too such as the Barney and Beavis/Butt-head version.

Id Software has been acquired by ZeniMax Media Inc.  Id Software is the company that created the games franchises Doom, Quake, Wolfenstein, Rage, and ommander Keen.  ZeniMax is the parent company of gaming company Bethesda, who created games such as Fallout 3 and The Elder Scrolls IV: Oblivion.

Id Software started in 1991 and built a proprietary gaming engine called id Tech.  No changes will be made after the acquisition is made in terms of management or relocation.  The principals at id Software have signed long-term employment contracts as well.

Zenimax started in 1999 and is based in Rockville, Maryland with offices in London and Tokyo.  The financial details were undisclosed.
