Robert Greenblatt:
"The Sing-Off was this little gem gestating in December, and it saw growth last year despite no promotion and no marketing. It was this little thing that came out of the blue, and we thought, let's take that and turn it into a franchise that would be really strong for us. I love the show, there's no reason this can't become a real weekly franchise."


I'm just mainly excited that I don't have to wait until December. :-P haha. And it will last longer too!
That is such a good show!
