Scott Berkun in The idiot theory of news:

Non-news, news without context, is easy to generate. It takes less skill as a journalist to write these stories. Often these stories are more popular than better written stories about important things. The popular news is not the best news. The popular anything is rarely the best anything. The way we see the world is shaped by what sells best as news, rather than what will give us a realistic perspective on the world and our place in it.
