The Vulture has composed an alarming chart showing how many network television shows have taken hits in the ratings over the 2012/2013 season.

The vast majority of the nearly 90 series that had their second or higher season on ABC, CBS, NBC, Fox, and the CW lost ground among adults under 50...more than 50 series declined by double digits, nearly 30 fell by 20 percent or more, roughly a dozen gave back a quarter or more of their young audience, and an unlucky seven saw their ratings collapse by at least one-third.

It's not all bad news: A few shows like Supernatural, Grimm, and The Big Bang Theory actually gained viewers. Wait, the Big Bang Theory gaining additional viewers is bad news, too, isn't it? Anyway, network television seriously needs to change their model before the bottom drops completely out. I suspect that cable is going to have to do the same thing soon.
