I would exactly say that ER is being canceled. They had their series finale so it ended on it's own terms. Saying it was canceled would be like saying that Seinfeld was canceled.
That said, of all of those shows, I watch 24, Law&Order:SVU, Extreme Makeover:Home Edition, & The Biggest Loser. I used to watch CSI but ever since William Peterson left the show lost something and has officially jumped the shark IMO.
