# Operación Triunfo series 9

Operación Triunfo is a Spanish reality television music competition to find new singing talent. The ninth series, also known as Operación Triunfo 2017, aired on La 1 from 23 October 2017 to 5 February 2018, presented by Roberto Leal. It was the first season broadcast by RTVE, which aired the first three seasons, in thirteen years. Seasons 4–8 of Operación Triunfo aired on Telecinco, which discontinued the series in 2011 due to declining ratings. RTVE approved to revive the series with a budget of 10.2 million euros.
In addition to the Galas or weekly live shows on La 1, daily recap shows aired on Clan, and the side show El Chat aired on La 1 after each weekly Gala, hosted by Noemí Galera. The activities of the contestants at "The Academy" or La Academia were streamed live via YouTube and the subscription platform Sky España.
Amaia Romero was announced the winner on 5 February 2018. Aitana Ocaña came second. Miriam Rodríguez ranked third, Alfred García fourth and fifth place went to Ana Guerra.
On 4 December 2017, during sixth week's live show or "Gala 6", it was announced that the series would serve as the platform to select the Spanish entrant at the Eurovision Song Contest 2018. On 20 December 2017, TVE announced that the five contestants that would succeed in advancing to the series' final would also be the five candidates to represent Spain at Eurovision. The live show that selected the Spanish entrant and song for Eurovision took place on 29 January 2018. Alfred García and Amaia Romero were selected with the song "Tu canción".
The ninth series turned into a media success in Spain, which was compared to the success of the original series of Operación Triunfo sixteen years before. Some of the contestants from this series such as Amaia Romero, Alfred García, Aitana, Miriam Rodríguez, Ana Guerra, Cepeda, Agoney, Mimi Doblas, Roi Méndez, Raoul Vázquez or Mireya Bravo went on to launch solo projects.

## Galas

The Galas or live shows began on 23 October 2017. In the introduction live show or Gala 0, 18 candidates were presented to enter the "Academy." Each contestant performed a cover version of a popular song of their choice, and two of the candidates were eliminated. For the regular galas, the contestants are assigned a popular song to perform in a duet or solo. The audience votes for their favourite performer, and the contestant with the most votes is exempt for nominations. The jury panel comments on the performances and nominates four contestants for eviction. The Academy's staff meeting saves one of the nominees, and the safe contestants save another of the nominees. The two remaining nominees prepare the performance of a song of their choice each for next week's live show, where one of the contestants will be saved by the audience via televote, sms and app voting. Each gala features a guest judge and guest performers.
