TV Ratings: ‘Rock Center,’ ‘House’ struggle as ABC, CBS split sluggish Halloween Monday

Fast National ratings for Monday, October 31, 2011.
Whether you choose to attribute lower-than-normal viewership on Monday night to typical Halloween doldrums or to ongoing power outages on the East Coast, the bottom-line results were ultimately unchanged: ABC won the night overall, while CBS had no trouble winning among young viewers.
Whatever caused the viewership drop, FOX was particularly impacted with both “Terra Nova” and “House” slumping to season lows. The news was also bad for NBC’s “Rock Center with Brian Williams,” which tanked in its Monday premiere.
