Within the gun community, popular media is often credited with teaching gun enthusiasm to younger generations. Particularly video games and internet videos. But these aren't traditional advertising, gun manufacturers (mostly, not always) don't pay for these things, and a law banning people from producing such media with their own funds would surely be unconstitutional.
Also I don't think the public is up for another round of geriatric politicians trying to ban violent video games.
