Doom (1993 video game)
Because id planned to self-publish the game, as the game neared completion they had to set up the systems to sell the game. Jay Wilbur, who had been brought on as CEO and sole member of the business team, planned the marketing and distribution of "Doom". He felt that the mainstream press was uninterested in the game, and as id would make the most money off of copies they sold directly to customers—up to 85 percent of the planned US$40 price—he decided to leverage the shareware market as much as possible, buying only a single ad in any gaming magazine. Instead, he reached out directly to software retailers, offering them copies of the first "Doom" episode for free, allowing them to charge any price for it, in order to spur customer interest in buying the full game directly from id.
Cyberdemon
The Cyberdemon is a fictional character in the "Doom" gaming-franchise by id Software, where it was introduced in the first-person shooter game "Doom" in 1993. It has appeared in several other id games, including all main-line "Doom" sequels, "Doom RPG", and "Wolfenstein RPG" as the Harbinger of Doom, along with other related media. The Cyberdemon became one of the most iconic characters of the "Doom" series along with its protagonist, the "Doomguy", and is often described as one of the most memorable bosses in video gaming history.
