The first-person shooter video game Halo 3 was the focus of an extensive marketing campaign which began with the game's developer, Bungie, announcing the game via a trailer at the Electronic Entertainment Expo in May 2006. Microsoft, the game's publisher, planned a five-pronged marketing strategy to maximize sales and to appeal to casual and hard-core gamers. Bungie produced trailers and video documentaries to promote the game, partnering with firms such as Digital Domain and Weta Workshop. Licensed products including action figures, toys, and Halo 3-branded soda were released in anticipation of the game; the franchise utilized more than forty licensees to promote the game, and the advertising campaign ultimately cost more than $40 million.
While Halo 2's release had set industry records, the mainstream press was not fully involved in covering the game; part of Microsoft's strategy was to fully involve casual readers and the press in the story. The saturation of advertising and promotions led Wired to state: "The release of Halo 3 this week was an event that stretched far beyond our little gaming world. Everyone from The New York Times to Mother Jones wanted to cover it."
Released on September 25, 2007, Halo 3 became the biggest entertainment debut in history, earning more than $170 million in a few days and selling a record 3,300,000 copies in its first week of sales alone.Halo 3's marketing won several awards, and was cited as evidence of the increasing mainstream popularity of games.
Jerret West, a global group product manager from Microsoft, said at a marketing conference that Halo 3's marketing team had a mandate from Microsoft executive Peter Moore: "Don't screw up." Much of the marketing organization was handled by Microsoft's former corporate vice president of global marketing, Jeff Bell (executive). A key challenge the team identified early on was that core gamers knew the game was coming out, but there was "a perception problem... we wanted to invite people into the console and into Xbox 360 and to play Halo 3 as a mass-market entertainment product," according to product manager Chris Lee. Since Halo 3 was released as an Xbox 360 exclusive, part of the marketing push was to sell more Xbox consoles, which had encountered sluggish sales.
