Development of Doom
The development of "Doom", a first-person shooter video game by id Software, began in November 1992 and continued until the game was released in December 1993. Seven people worked on "Doom", which is considered one of the most significant and influential titles in video game history. The initial development team was programmers John Carmack and John Romero, artists Adrian Carmack and Kevin Cloud, and designer Tom Hall; late in development Hall was replaced by Sandy Petersen and programmer Dave Taylor was added to the team. The music and sound effects were created by Bobby Prince.
Duke Nukem (character)
Duke Nukem was initially created in 1987 by chief programmer Todd Replogle of Apogee Software (now 3D Realms) as the protagonist for the video game he was designing titled "Metal Future," which was set in the then-near future of "one decade later from now" in 1997. After hearing the character's name, producer and founder of Apogee, Scott Miller, suggested the game should have the same name, and he helped design the character. Artwork was produced by George Broussard, Allen H. Blum III, and Jim Norwood. Duke was not voiced, but spoke through on-screen text.
