Fast National ratings for Wednesday, December 12, 2012.
 
"Survivor: Philippines" and "CSI: Crime Scene Investigation" both won their hours both overall and among young viewers, helping CBS carry Wednesday night in both measures. 
 
Among other ratings notes, NBC saw the third night of "Take It All" plummet without its "Voice" lead-in, going from marginal success to the dud in the matter of one night. NBC also saw "Chicago Fire" squander some of its recent momentum.
 
Meanwhile, it was another week of slight declines for The CW's "Arrow," though the netlet got a decent resampling for an encore of CBS' "Victoria's Secret Fashion Show."
