"Operación Triunfo" (also known as "OT") first aired in 2001. On its first run between 2001 and 2004, three series were aired on TVE, which also served as the national final to select the Spanish entry for the Eurovision Song Contest. The first series of "OT" was particularly successful in ratings, becoming one of the most popular shows in the history of Spanish television and featuring singers that went on to enjoy long-term recognition from the public: notably Rosa López, David Bisbal, David Bustamante or Chenoa. After the third series, TVE decided not to renew the show and its rights were acquired by Telecinco, which aired series 5–8 of the series. Series 8 in 2011 was cancelled due to poor ratings and its finale was rushed as a result.
