Fast National ratings for Tuesday, October 25, 2011.
 
The start of live shows for "The X Factor" delivered the talent show's best ratings since its premiere and carried FOX to a comfortable Tuesday win among young viewers. For all of the talk of "X Factor" as "disappointing," FOX has to be pleased both with a numbers bump at a point in the season that "Idol" has never returned to premiere levels and with a bump for a show that has had an erratic airing pattern due to baseball in recent weeks.
 
Of course, "X Factor" and FOX still couldn't compete with CBS' powerful "NCIS" double-dip, which carried the network to an easy overall win.
 
Among adults 18-49, FOX averaged a 4.3 rating for the night, beating CBS' 3.4 rating in the key demographic. There was a big drop to ABC's 2.3 rating and then to the 1.6 rating for NBC. The CW averaged a 0.3 rating for a night of repeats.
 
Overall, though, CBS averaged an estimated 15.4 million viewers in primetime to go with a 9.5 rating/15 share. FOX was second with 11.78 million viewers, beating the 10.56 million viewers for ABC. NBC was far back with a 3.0/5 and 4.6 million viewers, while The CW averaged 923,000 viewers and a 0.7/1.
 
[Univision averaged 3.32 million viewers in primetime along with a 1.4 rating among adults 18-49.]
