A report released on April 3, 2006 by the Harvard School of Public Health suggests that 80 percent of M-rated video games include sex, violence, profanity, gambling or drug and alcohol use which is not described on the labels. Though the video games in question are labelled 'M"? for Mature, pursuant to guidelines by the Entertainment Software Rating Board, the report's authors are concerned that parents and physicians recognize that M-rated video games may contain a wide range of unlabeled content.
