In Doom, players assume the role of an unnamed space marine, who became popularly known as "Doomguy", fighting his way through hordes of invading demons from Hell. With one-third of the game (nine levels) distributed as shareware, Doom was played by an estimated 1520 million people within two years of its release, popularizing both the business model of online distribution and the mode of gameplay, and spawning a gaming subculture. In addition to popularizing the FPS genre, it pioneered immersive 3D graphics, networked multiplayer gaming, and support for customized additions and modifications via packaged files in a data archive known as "WADs". As a sign of its effect on the industry, first-person shooter games from the genre's boom in the 1990s, helped in no small part by the game's release, became known simply as "Doom clones". Its graphic violence, as well as satanic imagery, made Doom the subject of considerable controversy.
The Doom franchise was later continued with the follow-up Doom II: Hell on Earth (1994) and numerous expansion packs, including Master Levels for Doom II (1995), and Final Doom (1996). Originally released for MS-DOS, the games have later been ported to numerous other platforms. Once the game's source code was released in 1997, it spawned even more adaptations, as fans further ported the code to countless devices. The series started to lose mainstream appeal as the technology of the Doom game engine was surpassed in the mid-1990s, although fans have continued making Wads, speedruns, and modifications to the original. The franchise again received popular attention in 2004 with the release of Doom 3, a retelling of the original game using id Tech 4, with an associated 2005 Doom motion picture. Another release, simply titled Doom and powered by id Tech 6, was released in 2016 and focused on returning to the fast paced action of the first two games.
Doom has appeared in several forms in addition to video games, including a Doom comic book, four novels by Dafydd Ab Hugh and Brad Linaweaver (loosely based on events and locations in the games), a Doom board game and a live-action film starring Karl Urban and The Rock released in 2005. The game's development and impact on popular culture is also the subject of the book Masters of Doom by David Kushner.
The Doom series remained dormant between 1997 and 2000, when Doom 3 would finally be announced. A retelling of the original Doom using entirely new graphics technology and a slower pace survival horror approach, Doom 3 was hyped to provide as large a leap in realism and interactivity as the original game and helped renew interest in the franchise when it was released in 2004, under the id Tech 4 game engine.
The series would again remain dormant for 10 years until a remake, simply titled Doom and running on the new id Tech 6, was announced with a beta access to players that had pre-ordered Wolfenstein: The New Order. The game held its closed alpha multiplayer testing on October 2015, as closed and open beta access ran during March to April 2016. Returning to the series' roots in fast paced action and minimal storytelling, the full game eventually released worldwide on May 13, 2016. The project initially started as Doom 4 in May 2008, set to be a remake of Doom II: Hell on Earth and ditching the survival horror aspect of Doom 3. Development completely restarted as id's Tim Willits remarked that Doom 4 was "lacking the personality of the long-running shooter franchise".
