Talpa's singing competition format remains strongest with blind auditions.
As U.S. ratings prove, The Blind Auditions is still the strongest part of Talpa's format, achieving 3.9-4.1 rating in the young demo on NBC (live+SD). The Battles were still strong with 3.8 rating, decreasing to 3.2 only with last 4th battle. Later phase called The Knockouts was able to achieve 3.0 ratings, which seemed impossible for Live Performances as all of them were below 3.0. Live shows tend to be the least-watched despite Talpa's attempt to improve the season cycle of 'The Voice' format.
