That is so true. TV gobbles up so much, so fast, constantly, that there's little time for anything creative or well worth watching; and the reality shows have hit rock bottom. No subtlety, gimme, gimme, gimme; and it won't change until they realize there's no more money to be made.
I agree and really hate what passes for entertainment on tv for the most part; it is poisonous for our children. I try to limit it as much as possible for my 8 year old, but kids somehow always find a way to glom onto the current culture, mostly through public school. That's why next year she is going to a Christian Academy.
But you are so right, when the interest in these voyeuristic programs dry up, the money will run out. And that will be it for this particular cultural garbage scow.
