Fast National ratings for Thursday, October 24, 2013.
 
"Big Bang Theory" was still Thursday's most watched show in most measures, but Game 2 of the World Series took a big bite out of the hit comedy overall and helped FOX cruise to nightly wins.
 
The competitive game between the Red Sox and Cardinals also took audience from ABC's "Scandal" and from CBS' "The Millers" and "Crazy Ones," but it wasn't all bad news. Both "Two and a Half Men" and "Elementary" were up after last week's dismal performances, while NBC's "Sean Saves the World," "The Michael J. Fox Show" and "Parenthood" all at least stayed flat. And, for the first time, "Sean Saves the World" outdrew "Michael J. Fox," becoming the first NBC comedy in several weeks to top 4 million viewers.
 
And, predictably, The CW's "Reign" took a drop in its second week, but with "Vampire Diaries" also slipping, it's doubtful The CW will be hugely concerned.
 
On to the numbers...
 
Among adults 18-49, FOX averaged a 3.2 rating for its two hours of Thursday primetime, beating CBS' 2.7 rating in the key demographic (the game rose as it progressed, so FOX's margin-of-victory is greater if you include its 10 p.m. hour). ABC averaged a 2.3 rating, followed by NBC's 1.3 key demo rating and the 0.9 key demo rating for The CW.
 
Overall, FOX averaged an estimated 12.25 million viewers and a 7.6 rating/12 share for its two Thursday primetime hours, followed by CBS' 10.29 million viewers and 6.4/10. ABC was third with 7.17 million viewers and a 4.9/8 for the night, followed by NBC's 4.36 million viewers and 2.9/5. The CW averaged a 1.4/2 and 2.17 million viewers.
