The Sing-Off was an American television singing competition featuring a cappella groups. It debuted on NBC on December 14, 2009, and was produced by Sony Pictures Television and Outlaw Productions, with Mark Burnett's One Three Media (for a time called United Artists Media Group) being added for the fourth season. A fifth season aired as a holiday special in December 2014.

Summary

It was hosted by Nick Lachey (from the boy band 98 Degrees), with judges Ben Folds, Shawn Stockman (of the rhythm-and-blues vocal group Boyz II Men), and originally Nicole Scherzinger, later replaced by Sara Bareilles. Bareilles left the show after the third season and was replaced by Jewel for the fourth season. Several members of the show's music staff have come from the a cappella community, including Deke Sharon (music director/vocal producer), Bill Hare, Ed Boyer, Ben Bram, Robert Dietz, Christopher Diaz, and Nick Girard.

The Sing-Off

A cappella groups from the United States, including Puerto Rico, were chosen by audition and advanced in the competition based on judges' eliminations. Before the fourth season, the winners of the competition were determined by viewer votes during the finale.

The Sing-Off

The program has featured guest appearances by various popular artists, including Bobby McFerrin, Natasha Bedingfield, Jay Sean, Smokey Robinson, Neil Diamond, Boyz II Men, Flo Rida and Sara Bareilles.

The Sing-Off

The Sing-Off was renewed for a third season and started to air much earlier on September 19, 2011, though the first two seasons had been broadcast in December. Unlike previous seasons, the early start in September allowed for the production of more episodes and the number of participant groups increased.

The Puerto Rican group Nota won the title for the inaugural season in 2009. For season 2, Committed from Huntsville, Alabama, took the 2010 title, and for season 3, Pentatonix from Arlington, Texas, won the 2011 title. The country group Home Free from Minneapolis, Minnesota, won the 2013 title for season 4.

On May 13, 2012, The Sing-Off was not renewed for another season, presumably cancelled after three seasons. However, on March 13, 2013, almost a year after the show was not renewed, NBC announced that The Sing-Off would return for a fourth season.

On December 17, 2014, NBC aired a special two-hour episode of The Sing-Off, billed as "Season 5" of the show. The special was filmed at the Dolby Theatre in Los Angeles and featured six competing groups, with the Vanderbilt Melodores being crowned the champions.

Series overview

Season 1 (2009)

The show featured eight a cappella groups performing popular songs live. The winner's prize was $100,000 and a Sony Music recording contract.

The first episode saw all groups perform their signature song. The second episode saw the remaining six groups perform two songs: in the first half of the show, each group performed one big hit from recent years; and in the second half, each group sang one "guilty pleasure" song. The third episode had the five remaining groups perform a medley from a classic artist. In the second part of the show, the four remaining groups performed songs that the judges picked specifically to showcase each group's strengths.

At the end of the third show, viewers were asked to call or text to vote for one of the remaining groups, Voices of Lee, The Beelzebubs, and Nota. The group with the most votes was revealed in the finale, and in the end Voices of Lee was revealed to come in third place halfway through the finale, with Nota being declared winners.

Season 2 (2010)

In the second season, the show returned on December 6, 2010, for five episodes, with the number of groups increased from eight to ten. Nick Lachey returned as host for the second season, as well as the three judges Ben Folds, Shawn Stockman and Nicole Scherzinger.

The first episode had the groups sing their signature songs. In the second episode, the remaining eight groups sang a modern song that was released in the past five years. For the third episode, the groups covered a rock song and a "guilty pleasure" piece. The fourth episode was to sing a medley of songs by a noteworthy artist and perform a song chosen by the judges. One more group was supposed to be eliminated, but the judges chose to put Jerry Lawson and The Talk of the Town, The Backbeats, Street Corner Symphony, and Committed all through to the finale. This is the only season to have four groups in the finale.

At the finale, Jerry Lawson and The Talk of the Town was the first to be eliminated. The Backbeats came in third place, Street Corner Symphony came in second, and Committed won the title.
