Two congressmen have introduced a bill that would require almost all video games to feature a warning label concerning exposure to violent games, similar to the health warnings on tobacco products.

Called the Violence in Video Games Labeling Act (H.R. 4204, PDF link), the bipartisan bill seeks to label games in the U.S. with a message that reads "WARNING: Exposure to violent video games has been linked to aggressive behavior" on their packaging (or in another clear and conspicuous location, if distributed digitally).

"Just as we warn smokers of the health consequences of tobacco, we should warn parents — and children — about the growing scientific evidence demonstrating a relationship between violent video games and violent behavior," said Virginia Representative and the bill's co-sponsor Frank Wolf, according to The Hill.

California Representative Joe Baca, who also co-sponsored the bill, added, "The video game industry has a responsibility to parents, families and to consumers — to inform them of the potentially damaging content that is often found in their products. They have repeatedly failed to live up to this responsibility."
