And some much-needed common sense, from Ben Compaine.

If large segments of the public choose to watch, read, or listen to content from a relatively small number of media companies, that should not distract policy makers from the key word there: choose. At a time when such a fragmented audience is dividing itself among niche cable channels, tens of thousands of book titles published annually, and hyper-individualized Web surfing, it may even be socially positive that there are some mass audience shows, movies, and books that, like the Harry Potter series, give us something common to talk about. It may indeed be that at any given moment 80 percent of the audience is viewing or reading or listening to something from the 10 largest media players. But that does not mean it is the same 80 percent all the time, or that it is cause for concern.
