Id Software

id Software is an American video game developer based in Richardson, Texas. It was founded on February 1, 1991, by members of the computer company Softdisk, including programmers John Carmack and John Romero, artist Adrian Carmack, and game designer Tom Hall.

Background
The company is known for its development of the Wolfenstein, Doom, and Quake franchises. On June 24, 2009, it was announced that id Software had been acquired by ZeniMax Media, owner of Bethesda Softworks. ZeniMax Media was acquired by Microsoft in March 2021 and id Software then became part of Xbox Game Studios.

On November 5, 2009, Carmack commented on id Software's involvement in the development of an iPhone Fallout game, stating that, while it was nothing official, he had an internal proof of concept for the game. Carmack said that he "at the very least" was "going to be providing code."

Fallout 76
id Software provided development assistance on Fallout 76, in the form of additional programmers. Specifically, they assisted with netcode from Quake Champions to support the multiplayer functionality needed to realize the game.
