Fast National ratings for Tuesday, August 9, 2011. 
 
For the third straight week, "Hell's Kitchen" carried FOX to a Tuesday win among young viewers, while "America's Got Talent" gave NBC an easy Tuesday win overall. 
 
It's of some note that with "Hell's Kitchen" rising slightly each week and "America's Got Talent" falling slightly each week, FOX's advantage in the advertiser-friendly demo has been growing, while NBC's advantage in total viewers has been dwindling.
 
Among adults 18-49, FOX averaged a 2.6 rating for the night, beating NBC's 2.3 rating in the key demographic. ABC's 1.5 rating and the 1.4 rating for CBS followed. The CW averaged a 0.3 rating.
 
Overall, though, NBC averaged an estimated 8.92 million viewers and a 5.3 rating/9 share to win the night. CBS averaged a 5.4/9, but ranked behind NBC with 8.18 million viewers. FOX was a distant third with 6.205 million viewers and a 3.6/6, beating the 2.7/5 and 4.72 million viewers for ABC. The CW averaged a 0.5/1 and 665,000 viewers.
 
[Univision averaged 2.94 million viewers and a 1.2 key demo rating for the night, beating The CW. Then again, Telemundo and Ion also handily topped The CW for the night.]
