ABC’s Wipeout had the edge in its second week against CBS’ Big Brother at 8 PM on Thursday. After Big Brother narrowly won last week (2.5/9 to 2.4/8 after being tied at 2.4/9 in the fast nationals), Wipeout (2.5/9) last night was up a tenth, while Big Brother (2.3/9) was down two tenths from its season premiere last week. But the live eviction Big Brother show was up double digits from the comparable broadcast last year. Fox’s So You Think You Can Dance (1.9/6, down 10%) also had its results show last night but the its ratings were probably affected from the fact that the elimination was a foregone conclusion after a dancer (Ashley) was injured.

Meanwhile, Wipeout‘s ratings uptick was followed by more gains for the network’s scripted drama Rookie Blue (1.7/6, up 13%) and docu series ABC News Boston Med (1.3/4, up 18%). ABC won the night in adults 18-49 (1.8/6), while CBS, which aired drama repeats after Big Brother, was tops in viewers (7.1 million) NBC aired all-reruns.
