It looks like the singing is over for The Sing-Off on NBC — at least for now.

The a capella singing competition debuted in December 2009 and ran for just four episodes. It was renewed for a second season of five episodes. The network execs then decided to try The Sing-Off as a regular fall series but the ratings really suffered.

It was believed to be cancelled but NBC revived the show for a fourth season that aired during the holidays to low ratings.

A fifth season was ordered but the network ended up making it a two hour special instead. That aired December 17, 2014 and drew more low ratings.

There’s been no word on the fate of The Sing-Off in over a year and the NBC site hasn’t been updated since December 2014. What’s more, the official casting site still reflects the Fall 2014 audition information.

So, it appears that the show is over — at least for now. Networks bring shows back all the time these days so the series certainly could be revived at some point in the future.

What do you think? Do you like The Sing-Off TV show? Would you like to see it return for a sixth season at some point in the future?
