NBC has renewed three unscripted programs for the 2011-12 season, including the popular weight-loss competition series The Biggest Loser.
Who Do You Think You Are?, from Lisa Kudrow, and the singing competition series The Sing-Off are also returning, NBC Entertainment chairman Bob Greenblatt announced Tuesday.
“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,” said Greenblatt. “They are each unique, attention-getting shows with terrific producing and talent auspices, and we’re proud to be associated with them.”
The 10th cycle of The Biggest Loser averaged a 3.1 rating in the key 18-49 demo and roughly 8.3 million viewers. Its current season, The Biggest Loser 11, with new trainers Brett Hoebel and Cara Castronuova, averages a 3.3 and 9 million viewers.
The second season of Who Do You Think You Are? is doing OK, averaging a 1.4 and 7 million for its first two episodes. The most recent season of The Sing-Off averaged a 3.2 and 9.2 million, a 28% increase in the demo and 27% in total viewers compared to last season.
