Fast National ratings for Thursday, June 9, 2011.
 
The Dallas Mavericks are hoping to end the NBA Finals in only one more game, but you can't blame ABC for hoping the Miami Heat stretch the series to seven. Game Five of the NBA Finals, yet another close contest into the waning moments of the 4th Quarter, drew the series' biggest audience to date and helped ABC to a Thursday rout in all measures.
 
Among adults 18-49, ABC averaged a 5.1 rating for the night, easily tops in the key demographic. FOX was a distant second with a 2.4 rating, far ahead of CBS' 1.4 rating and the 0.8 rating for NBC. The CW averaged a 0.3 rating.
 
Overall, ABC averaged an estimated 12.91 million viewers and a 7.6 rating/13 share. CBS moved up to second with a 4.6/8 and 7.24 million viewers, beating FOX's 4.2/7 and 6.94 million viewers. There was a big drop to NBC in fourth with 1.5/3 and 2.17 million viewers. The CW averaged 973,000 viewers and a 0.7/1 for the night.
