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.
Doom (1993 video game)
With the release of "Doom", id Software, quickly found itself making $100,000 daily. Sandy Petersen later remarked that the game "sold a couple of hundred thousand copies during its first year or so", as piracy kept its initial sales from rising higher. Experts estimate that the game sold approximately 2-3 million physical copies from its release through 1999. According to PC Data, which tracked sales in the United States, the "Doom" shareware edition sold 1.15 million copies by September 1999. The "Ultimate Doom" SKU reached sales of 787,397 units by that date. At the time, PC Data ranked them as the country's eighth- and 20th-best-selling computer games since January 1993. In addition to its sales, the game's status as shareware dramatically increased its market penetration. "PC Zone"s David McCandless wrote that the game was played by "an estimated six million people across the globe", while other sources estimate that 10–20 million people played "Doom" within 24 months of its launch.
