I just watched this short (35 min) documentary called "Sexy Inc.; Our Children Under Influence". It's a critical look at the hyper-sexualized culture that children are being exposed to at younger and younger ages and some speculation on how it affects them. It also looks at the sexualization of children in the media. The discussion gets quite graphic at certain points, just to warn. No real surprises in it, but I feel it's worth a watch.
