The complicated economics of an all HD channel
While you're kicking back and enjoying some HD content on a lazy Sunday it is easy to give little regard to the economics that make that HD content possible. Most don't care much about what makes the world go around, but if you've always wondered why there aren't more all-HD channels, this recent post over at Multichannel news is worth the read. Most notable is the challenges all-HD networks face including the fact that Nielsen doesn't even provide rating for them. If you're a big Mark Cuban fan you might also find it interesting as a number of his quotes are included like when he says "We really think that as our distribution continues to grow, we can dominate the demographic (13-34 males)."
