A Federal Trade Commission study has concluded that violent entertainment products are being marketed to children. The year-long study focused on movie studios, record companies, and video game producers. The report found that videogame companies often placed ads for games with mature content in magazines geared towards young teens and pre-teens. The report scheduled for release next month, and Senate Commerce Committee is planning a hearing. Vice presidential candidate Sen. Joseph Lieberman, a leading critic of violence in entertainment, has reportedly expressed an interest in testifying.
