Check out THR for more behind the scenes details of The Voice.
From THR:
Though the show costs less to produce than a scripted hour, the $2.3 million price tag is more than the network would pay to license a first-year drama (about $2 million). The network maintains that the show's production values are high and that it had to spend to compete with such established giants as Idol as well as X Factor, which will launch as if it were established. The talent is pricey, too. Knowledgeable sources say Aguilera is pulling down more than $225,000 per hour; the other coaches about $75,000 each.
