Fast National ratings for Thursday, May 26, 2011.
 
The eighth installment of "So You Think You Can Dance" posted solid year-to-year gains for FOX and helped the network win the important ratings races on the first night after the end of the 2010-2011 season. 
 
"So You Think You Can Dance" was, in fact, the only non-repeat on any of the five networks, so just assume that any other listed program was, indeed, in repeats.
 
Among adults 18-49, FOX averaged a 3.2 rating for the night, easily beating the 1.7 rating for CBS in the key demographic. ABC's 1.0 rating and the 0.9 rating for NBC followed, with The CW's 0.3 rating finishing last.
 
Overall, FOX averaged an estimated 5.1 rating/9 share and 9.1 million viewers, while CBS averaged the same 5.1/9, but only 8.09 million viewers. ABC was a distant third with a 2.6/4 and 4.12 million viewers, still ahead of the 1.6/3 and 2.43 million viewers for NBC. The CW averaged 0.6/1 and 956,000 viewers.
 
[That 9.1 million viewers and 3.2 demo rating for the totality of the "So You Think You Can Dance" premiere was up from under 8.2 million and a 3.0 demo rating in Fast Nationals for last May's "SYTYCD" two-hour launch.]
