GameDaily reports on how Halo 3's marketing molded the image of Master Chief. Jerret West, global group product manager at Microsoft, explains they didn't want to portray Master Chief "as a reckless American cowboy." They needed him to be accepted as a savior of humanity and integrate Halo into pop culture. West notes the team had pop culture benchmarks like making the cover of Time or Wired, and worked with numerous other companies to push marketing ideas.
Chris Lee, a product manager from Microsoft, points out that Halo didn't have an awareness problem, it had a perception problem for being too hardcore. Looks like the team's efforts to make the Master Chief mainstream worked out. Halo 3 ended up becoming one of the best selling games last year.
