NBC completely screwed themselves over. All they had to do was take Studio off on Thursday's at 9. Instead, they've hurt the ratings of 2/3 Law & Orders, put Crossing Jordan into a swan-song corner, and completely tossed Medium to the side like it's nothing. They had no idea what they're doing and they wonder why they're in 4th place.
EDIT - AND they put 30 Rock opposite Dancing With The Stars. WTF?
