The Voice Seasons

Superstar singer-songwriter Kelly Clarkson makes her debut as a coach this season, with Season 12-winning coach and musical icon Alicia Keys taking a red chair alongside the show's returning coaches, Adam Levine and Blake Shelton, and host Carson Daly.

In season 13, superstar singer, songwriter, actress and pop-culture icon Miley Cyrus returns as a coach with Oscar, Grammy, Golden Globe-winning recording artist and Broadway star Jennifer Hudson taking a red chair alongside the show's returning coaches Adam Levine and Blake Shelton and host Carson Daly.

In season twelve, Grammy Award-winning artist Gwen Stefani returns as a coach, joining megastars Alicia Keys, Adam Levine and Blake Shelton and host Carson Daly.

Celebrity musicians and original coaches Adam Levine and Blake Shelton return with new coaches Pharrell Williams and Gwen Stefani, while Carson Daly continues to serve as host.

The fifth season of The Voice of the American reality singing competition premiered on September 23, 2013 on NBC. Coaches Christina Aguilera, Cee Lo Green, Adam Levine, and Blake Shelton will be returning, reinstating the original lineup after Aguilera and Green were replaced by Shakira and Usher in the previous season. Carson Daly will also return to host the show.

The fourth season is the first season to feature Usher and Shakira as coaches, with Cee Lo Green and Christina Aguilera taking a break for their music career. The team sizes were trimmed back down to 12 per team, with each coach having two 'steals' in the Battle Rounds.

For this season, teams increased to 16, up from 12 last season. In addition, during the battle round, opposing coaches have the ability to steal the singer that was sent home by the original coach. If more than one coach hits their button to recruit the singer in question, it is up to the contestant to decide which coach he or she wants to work with. Each coach can save two contestants, which means the battle round will end with ten singers on each team, rather than eight. A new two-night "knockout round" will begin after the battle round, where the coaches will reduce their teams to five. This was followed by a reduction of the teams to three each, with the two most voted for by viewers selected, along with one choice from the judge. After this, the show moved to a format more similar to American Idol or The X Factor, starting the top 12 and the top spots given to the 10, who received the most viewer votes.

All four coaches return for their second season. The season expanded from the first season: each coach has twelve artists on their team, rather than eight as in the first season. The blind auditions and the battle rounds have also been extended.
