The first season started its run on Sunday 13 May 2007. The show was then broadcast nightly with 'Los Castings' (the auditions), which lasted until 20 May 2007. From the 21 May until 27 May 2007 'La Selección Final' (final selection) was shown, again nightly. On 28 May 'Las Galas' (live shows) began. Factor X proved successful for TV channel Cuatro. It achieved an average rating of 12.3%. Factor X live shows were shown at 10pm every Monday evening.

The second season started its run 1 September 2008 with the auditions. The first "gala" or live show was aired on 22 September, on primetime. In a similar fashion to the last seasons in the original British version, each gala had a different theme (number-one hits or 80's music, for example). Five acts were chosen for the finals in each category, and an additional contestant was chosen in the middle of the season through Internet auditions

The third season premiered on Telecinco on 13 April 2018, ten years after its run on Cuatro.[6]

Telecinco initially announced a fourth season for 2019.[4] Alejandro Sanz and Isabel Pantoja were offered a slot in the jury,[20] but both reportedly declined.[21] In November 2019, the CEO of Fremantle Spain, Nathalie García, stated that there were no plans for a new season.[5]

A few weeks after the first season ended, eventual winner María Villalon released a debut EP entitled María Villalon, an album with all the songs she sang whilst in the competition. A few months later, she released her debut album Te Espero Aquí, which made the Spanish top 40 album chart, just like her debut LP did. But she wasn't the only one who received a record deal, runner-up Angy released her debut self-titled album (with the artistic name Angy) a couple of weeks after Villalon's debut album release. She also began an acting career starring in the teen drama television series Física y Química, aired on Antena 3. 3rd placed Walter released a single, but it didn't see much success. Angy's debut single 'Sola En Silencio' was a major hit across Spain, making the top 20 in Spanish Los 40 Principales. In turn, Maria Villalon's first two singles 'Aguita De Abril' and 'Te Espero Aqui' failed to gain chart stardom, but her second album saw the success of its lead single 'La lluvia' which made it into the top 5 in Los 40 Principales.

Months after the contest finished, 6th placed Leire Martínez's popularity boosted as she was chosen to replace Amaia Montero as the new lead singer of La Oreja de Van Gogh, one of the best-selling pop bands in Spain and Latin America.[22] Her first album with the band, A las cinco en el Astoria, was released on 2 September 2008 reaching the number-one spot in the Spanish charts.

8th placed Ailyn submitted a song to Salvemos Eurovisión, the Spanish selection for the 2008 Eurovision Song Contest, but failed to get to the final round. Later that year, she was chosen to be the new female vocalist of the Norwegian Gothic Metal band Sirenia, working with them until 2016.[23]

After the third season ended, judge Laura Pausini invited some of the contestants, including her pupils Samuel Hernández and series winner Pol Granch, to serve as opening acts for her upcoming world tour.
