As if the Olympics never happened — Fox’s So You Think You Can Dance (1.7/5 in adults 18-49) and the Wednesday edition of NBC’s America’s Got Talent (2.2/6) returned from their two-week hiatuses matching their last pre-Olympics originals. CBS’ Big Brother (2.1/7, 5.8 million viewers), which did not take time off, was up 11% from last week, when it faced primetime coverage from the London games, to post its highest Wednesday numbers among 18-49 and total viewers this season.

When you hit a 0.0 demo rating (0.0 in 18-49, 215,000 viewers for a June rerun of 90210), expectations are understandably low. By those standards, the CW’s new musical chairs-style competition Oh Sit! (1.3 million viewers, 0.5/2 in adults 18-34 and 18-49) did OK.

It posted the CW’s best 18-34 rating of the summer and surpassed the underwhelming debuts of The Catalina (994,000; 0.3 in 18-34 and 18-49) and Breaking Pointe (963,000; 0.4 in 18-34, 0.3 in 18-49) to become the network’s most-watched and highest-rated reality series premiere this summer. It also did far better than the in-season debuts of the CWs midseason reality series Remodeled (707,000 viewers and 0.3 in 18-49) and scripted drama LA Complex (646,000 viewers, 0.3). Overall, NBC (6.2 million, 1.6/5) won last night in total viewers, Fox (4.7 million, 1.7/5) in 18-49.
