They're the people who give games their ratings. "E for Everyone", "T for Teens", "M for Mature", etc. When Mortal Kombat was released, it had to be given a warning for how adult it was due to the blood and violence in it, this eventually the ESRB was formed and began giving games their ratings. Or something like that. Either way, Mortal Kombat was the reason for all that.
