Fast National ratings for Thursday, August 9, 2012.
 
Numbers from Thursday night's Olympics telecast were way down for NBC, as viewers showed relative disinterest in Usain Bolt's 200-meter win, lots of diving, David Rudisha's 800-meter world record and the rest of the evening's menu. Of course, NBC still ruled the night in all imaginable measures.
 
NBC averaged a 6.8 rating among adults 18-49 for Thursday night, easily best in the key demographic. CBS' 1.7 key demo rating and the 1.6 key demo rating for ABC followed. FOX posted a 1.0 key demo rating, while The CW did a 0.3 key demo rating.
 
Overall, NBC averaged an estimated 22.4 million viewers and a 13.4 rating/22 share for Thursday primetime. CBS was far back in second with 5.83 million viewers and a 3.8/6, holding off the 5.06 million viewers and 3.0/5 for ABC. FOX averaged a 1.7/3 and 2.74 million viewers, beating the 774,000 viewers and 0.5/1 for The CW handily.
