I want to know the answer to the following question:
What organizations did the hearing about video game violence in 1993 lead to?
All the background I'm provided with is that "Game players were not the only ones to notice the violence in this game; US Senators Herb Kohl and Joe Lieberman convened a Congressional hearing on December 9, 1993 to investigate the marketing of violent video games to children.[e]". Is that enough to answer the question?
Answer: no
