The a cappella competition show from Sony Pictures Television and Mark Burnett's One Three Media will return as a holiday event. It's unclear how many episodes or what the airdate pattern will be. Casting for season 5 is currently under way.
NBC renewed The Sing-Off for a fourth season in 2013 -- after the show had been off the air for nearly a year and a half. The network broadcast the series last year as a seven-night event, similar to its original broadcast pattern before the series briefly switched to a weekly series in 2011. Season 4 ended with a record low for the franchise, with 5.2 million total viewers and a 1.3 among adults 18-49 when it aired on the day before Christmas Eve last year.
It's unclear which, if any, of season 4's judges and hosts will be back. Season 4 featured the returns of Nick Lachey, Shawn Stockmanand Ben Folds, with Jewelreplacing Sara Bareilles.
The return of The Sing-Off comes as NBC also has high-profile live musical Peter Pan in the works for a Dec. 4 broadcast.
