'Biggest Loser,' 'Sing-Off,' 'Who Do You Think You Are?' picked up for 2011-12

biggest-loser-jillian-michaels-leaving-alison-sweeney.jpgNBC has picked up three of its unscripted series, including "The Biggest Loser," for the 2011-12 season.

"The Sing-Off" and "Who Do You Think You Are?" also earned spots in next season's lineup. The news is not all that surprising, since all three shows have performed reasonably well this season. But the announcement is notable for being the first one made by new NBC chairman Bob Greenblatt, who took over the network in the wake of the Comcast-NBC Universal merger.

"Alternative series such as these three bona fide hits are important not only to their loyal audiences but also as strong components of the NBC schedule," Greenblatt says. "They are each unique, attention-getting shows with terrific producing and talent auspices, and we're proud to be associated with them."

"The Biggest Loser" has been one of NBC's most consistent performers in recent seasons. The show's fall cycle averaged 8.3 million viewers and a 3.1 rating in the adults 18-49 demographic; the current season is drawing 9 million people per week and a 3.3 in the demo.

"The Sing-Off" had a solid run in December, averaging 9.2 million viewers over its two weeks and improving considerably over its debut in 2009. "Who Do You Think You Are?," meanwhile, scores about 7 million viewers a week on Friday nights.
