I feel you are misunderstanding what is happening in media. There are a lot of things going on.
A)Traditional media is fragmenting to a very, very large degree. Much smaller shows and movies for very targeted audiences. The spectrum has widened. Are there wholesome shows out there? Yes, more than ever before. But there are also shows of questionable taste.
B)The means by which entertainment is delivered and consumed has multiplied. Entertainment is portable. You can watch movies on an iPod. This impacts viewing habits and tastes, as does things like movies on demand and DVRs.
C)Entertainment companies are in a death match for viewship. More competition from video games, the internet, etc.
D)Idiot parents have not taught their kids how to consume entertainment. It’s a product, not unlike a lot of other products, yet kids have no idea how to use it.
Remember, if ‘for the children’, just like SCHIP.
