ABC’s new reality series Expedition: Impossible (1.6/5) rebounded from last week’s low, up 23%. Still, the adventure series remained the lowest-rated unscripted offering for the night. On ABC, it was flanked by Wipeout (1.9/7) and scripted drama Rookie Blue (1.3/4), both flat with last week. CBS won the night paced by Big Brother (2.6/8) at 9 PM, which was also even with last week and once again the top-rated program on the night. The reality’s lead-in and lead-out were reruns. Fox’s So You Think You Can Dance result show (1.7/6), which featured a performance by this week’s guest judge Lady Gaga, was up 6% from last week. NBC aired wall-to-wall repeats to finish a distant fourth for the night.
