So... What About Those Effects?

I'm currently wondering. What would we do if we discovered, that media does effect children? What if media effected adults? What would that mean? Surgeon general warnings on televisions, game boxes, magazines, books, libraries? Even if you could prove that media-saturated environments do bad things to children, how would one go about making changes? It seems like we've put the cart in front of the horse. Shouldn't one understand how media is produced as well as how it is consumed? If you wanted to change the media or the saturation level, can you go about it without really knowing anything about where either of those things come from?

STUDY MEDIA PRODUCTION TOO.
