The channel was officially launched as
13TV on November 29, 2010 by renting a television frequency belonging to the group
Unidad Editorial. On September 30, 2015, the channel received its own frequency, which began broadcasting officially in 2016. Since its founding, the channel has shown its alignment with conservatives, something that intensified during the mandate of
Antonio María Rouco Varela as the head of the
Spanish Episcopal Conference, for which reason it was considered as a means of diffusion of the conservative wing of the
People's Party. On September 24, 2013,
Fox International Channels collaborated with 13TV to create a morning block of
BabyTV on weekends at 9:45am. In 2016 the Spanish Catholic Church commissioned a report on the situation of the channel due to the new social doctrine initiated by Pope Francis; the study showed that the channel needed to undergo reforms because public perception was that the signal was aimed at an elderly audience and sympathizers of the People's Party. The new direction of the Episcopal Conference considered the reform of the channel's content as a necessary step to maintain the finances of 13TV. In September 2017, the channel underwent an identity change, being renamed as
Trece in an attempt to improve the reputation of the signal and make it more appealing to a wider audience, as it had been seen to be very close to right-wing entities. The channel's new programming was based on current affairs, religion and cinema, especially
westerns, although some programming from the channel's previous schedule was maintained because they generated good audience numbers. In addition, integration with COPE was increased. Since 2017, the channel has been looking for a commercial partner to which it can allot part of its programming time to, in exchange for an infusion of capital. == Programming ==
