The Voice is an American reality television singing competition broadcast on NBC. Based on the original The Voice of Holland, the concept of the series is to find currently unsigned singing talent (solo or duets, professional and amateur) contested by aspiring singers, age 15 or over (reduced to 13 since season 12), drawn from public auditions. The winner is determined by television viewers voting by telephone, internet, SMS text, and iTunes Store purchases of the audio-recorded artists' vocal performances. They receive US$100,000 and a record deal with Universal Music Group for winning the competition. The winners of the fourteen seasons have been: Javier Colon, Jermaine Paul, Cassadee Pope, Danielle Bradbery, Tessanne Chin, Josh Kaufman, Craig Wayne Boyd, Sawyer Fredericks, Jordan Smith, Alisan Porter, Sundance Head, Chris Blue, Chloe Kohanski, and Brynn Cartelli.
