Plus if we don’t do anything about it now, rohan_2 twenty years from now will use the same argument about whatever comes next!

What policy proposals would you have made with respect to MTV decades ago, and how would people at the time have reacted to them? MTV peaked (I think) before I was alive or at least old enough to have formative memories involving it, but people have been complaining about television being brain-rotting for many decades and I'm sure there was political pressure against MTV's programming on some grounds or another, by stodgy cultural conservatives who hated freedom of expression or challenges to their dogma. Were they correct? Would it have been good for the US federal government in the 80s and 90s to have actually imposed meaningful legal censorship on MTV for the benefit of the mental health of its youth audience?

It matters because it points towards a common failure mode which we've seen repeatedly in the past. In the 1990s, people routinely published news articles like the OP (e.g. https://www.nytimes.com/1999/04/26/business/technology-digit...) about how researchers "knew" that violent video games were causing harm and the dastardly companies producing them ignored the evidence. In the 1980s, those same articles (https://www.nytimes.com/1983/07/31/arts/tv-view-the-networks...) were published about television: why won't the networks acknowledge the plain, obvious fact that showing violence on TV makes violence more acceptable in real life?

Is the evidence better this time, and the argument for corporate misconduct more ironclad? Maybe, I guess, but I'm skeptical.
