A heavily touted musical episode of Grey’s Anatomy was a time slot winner on Thursday: The special installment that featured Sara Ramirez and her impressive pipes earned a 4.8 rating/12 share — up 30 percent from last week — and 12.7 million viewers, according to early estimates. The episode ended up doing a solid for Private Practice, which saw a 4 percent boost in ratings (2.7/7, 7.6 million) versus last week.
Each 18-49 ratings point represents 1.3 million viewers.
Still, there was no battling the Death Star. American Idol rocked the night across the board in all demos and averaged 22 million viewers. Fox, as a result, won the night across all key demos and beat the next highest rated network by 68 percent in 18-49 (5.2 vs. ABC’s 3.1) and 36 percent in viewers (16.4 vs. CBS’ 12.1 million). Last night’s show was also up 7 percent in total viewers (22.0 million versus 20.5 million) compared to last year.
The stellar lead-in helped Mobbed (3.8/10, 10.8 million), Howie Mandel’s new unscripted show that stages unexpected flash mobs. It beat an original of CSI (2.8/7, 12.4 million) by 36 percent.
NBC ran repeats.
