Fast National ratings for Thursday, October 31, 2013.
 
"Its The Great Pumpkin, Charlie Brown" comfortably outdrew ABC's normal 8 p.m. dramas and helped the network lead Thursday night among young viewers. Overall, though, CBS won despite a repeat of "Big Bang Theory" leading to significant drops for both "The Millers" and "Crazy Ones."
 
While CBS' comedies were down, CBS can be enthusiastic about "Elementary" beating "Scandal" overall for the first time this season, even if "Scandal" still dominated "Elementary" among young viewers.
 
A "Saturday Night Live" Halloween special gave NBC a big boost in the 8 p.m. hour over the network's usual comedies and helped "Sean Saves The World" outdraw "The Michael J. Fox Show" for the second straight week and also top its 9 p.m. companion among young viewers.
 
Halloween siphoned a lot of viewers away from "The Vampire Diaries," but The CW can take some solace in flat week-to-week demos for "Reign." ["Vampire Diaries" was preempted in New York City, which may account for some of the decline.]
 
And, finally, an "X Factor" clip show drew no interest at all for FOX, which had been hoping this would be a night dominated by Game 7 of the World Series.
 
On to the numbers... Keep in mind that TV usage is appreciably lower on Halloween night.
