As if there weren't a surfeit of singing contests on network television already, NBC announced on Tuesday that it was adding yet another one. Titled The Winner Is , the series will feature singers "dueling" against one another for a $1-million cash prize. The weekly competition will also include game-show elements. For Example, a contestant will reportedly be able to leave the show and receive a predetermined cash prize before the verdict of a panel of judges is revealed -- or remain in the competition and risk losing everything. Executive producer is John de Mol, creator of CBS's Big Brother and NBC's highest-rated series, The Voice , which averages 15.8 million viewers .
