Spotted Ratings, Thursday 3/14/13

WHAT MATTERS:

• Took till Thursday, but we finally got a truly brutal post-daylight savings day in ratings, perhaps because there was a higher volume of originals. The damage was greatest in the 8:00 hour, when The Big Bang Theory, Two and a Half Men, American Idol and The Vampire Diaries were each down double-digits week-to-week, while Community gave back all of last week's gains and then some. The only week-to-week positive performance in that hour was Parks and Recreation.

• 9:00 was not spared from the carnage either, as Grey's Anatomy had a rough time as the only ABC original, and Glee took another of its typical second-episode-back drops.
