The game started out (in conception) as a tie-in with the film "Aliens", ultimately becoming its own project due to the developer wanting more creative freedom.
The Cacodemon is directly modeled off two characters from Dungeons & Dragons; The Beholder, and the Astral Dreadnaught.
Early versions of Doom had a swastika wall that lowers in E1M4 - Command Control, but it was later altered for obvious reasons. This is also a reference to their other games Wolfenstein 3D and Spear of Destiny.

It's heavily estimated that in 1995, Doom was the most-installed piece of software on home computers, even beating out Windows 95.
Doom 95, a re-release of the first Doom that ran under Windows instead of DOS, shipped with a manual that made many references to Doom II. Apparently, they just copied the Doom II manual, but tried (unsuccessfully) to remove all information irrelevant to the first game. For example, the Baron of Hell was described as "Like a Hell Knight, but worse," when the Hell Knight is a Doom II-only enemy. Done on purpose in The Depths of Doom Trilogy's manual, where the Cyberdemon and Spider Mastermind are marked "in Doom II only" so as not to spoil their boss fights in Doom 1.
