Fast National ratings for Wednesday, December 3, 2014.

On one hand, CBS' double-dose of "Survivor: San Juan Del Sur" came in below season averages, but the two episodes still carried the network to an overall win and a tie in the key demographic.

NBC also tied for first among young viewers with "Christmas in Rockefeller Center" and an airing of the "Saturday Night Live Christmas" special. 

On the positive side of the ledger, The CW's "Arrow" capitalized on the second part of its crossover with "The Flash" to deliver season highs in all measures, including a series high among adults 18-49. Based on this week's crossover numbers, you can probably expect to see a lot more of that in the future.

On the negative side, ABC's full comedy slate was down on Wednesday.

Among adults 18-49, NBC and CBS averaged a 1.9 rating for Wednesday night, tops in the key demographic. ABC was a close third with a 1.8 key demo rating. FOX's 1.1 key demo rating edged out The CW's 1.0 key demo rating for the night.
