Fast National ratings for Tuesday, November 13, 2012.
 
"Parenthood" topped "Vegas" among young viewers to help NBC score a narrow Tuesday win in the advertiser-friendly demographic, but nothing could stop CBS from sweeping primetime overall with its "NCIS" double-bill.
 
In the 9 p.m. comedy log-jam, dwindling ratings for FOX's "New Girl" have made NBC the big winner, while "Don't Trust the B---- in Apartment 23" continues to embody ABC's struggles. [The difficulties for "Ben and Kate" are a different story.]
 
And, finally, it was the most watched episode of "Hart of Dixie" since last December, which also boosted "Emily Owens, MD" and its chances for a back-nine order.
 
On to the numbers...
