In no particular order, my TV watching consists mostly of:
CNN
Hockey
Baseball
Dr. Who
Burn Notice
In Plain Sight
Later...with Jools Holland
River Monsters
Psych
Concerts on HDNet
Law & Order: Criminal Intent
Criminal Minds
...and the odd episodes of true crime shows like First 48, Wicked Attraction and Most Evil, as well as other mind-candy like World's Dumbest and Mythbusters
I recently gave up on Dexter. Love it though I do, I can't justify spending all that money on the movie package for Verizon FIOS just to watch Dex and the occasional movie. I'm better served buying the DVDs at some future point.
EDIT: Forgot- I watch a fair amount of the Food Channel, mostly Good Eats and Iron Chef.
