Singer, previously known as I Am a Singer, is a Chinese singing competition show broadcast on Hunan Television. It is based on the Korean show I Am a Singer. The competition was opened to well-known professional singers from the music industry across worldwide, and featured a rotating cast of singers performing each week, usually with seven singers, who performed in front of a 500-member audience. The votes cast from the audience were the sole determinant for the results and one singer who received the fewest votes is eliminated while a new singer substituted in place of that singer, featuring a constantly changing lineup of artists throughout the series. The first season featured 12 contestants, but later increased to as many as 22 due to twists and competition rules added in later seasons. The inaugural series was first taped on 10 January 2013 and premiered on 18 January 2013.
