Azteca Uno (formerly Azteca Trece) is a Mexican national broadcast television network owned by TV Azteca, with more than 100 transmitters across the country. Azteca Uno broadcasts on virtual channel 1. Azteca Uno programming is available in Mexico on satellite via Sky and Dish Network, as well as all Mexican cable systems, and some Azteca Uno programming were seen in the United States on Azteca América.
In 1972, due to debts owed to the state-owned Sociedad Mexicana de Crédito Industrial (Mexican Industrial Credit Society or SOMEX), XHDF and concessionaire Corporación Mexicana de Radio y Televisión were nationalized.
The first director of the government-owned Canal 13 was Antonio Menéndez González, and after his death, he was succeeded by Enrique González Pedrero, senator of the state of Tabasco from the PRI. Corporación Mexicana de Radio y Televisión, along with another state-owned enterprise, Tele-Radio Nacional, began receiving new television concessions as part of a national expansion of the Mexico City station into a national television network.
One of the first orders of business for Canal 13 was a relocation. On July 14, 1976, Canal 13's new facilities in the Ajusco area of Mexico City were formally inaugurated by President Luis Echeverría. The event was attended by various figures from the political and business sectors of the country, including Secretary of the Interior Mario Moya Palencia and Secretary of Communications and Transportation Eugenio Méndez Docurro, as well as Emilio Azcárraga Milmo, Romulo O'Farrill and Miguel Aleman Velasco, who served as directors of Televisa.
In 1983, the Mexican government reorganized its broadcast holdings. The result was the creation of the Mexican Television Institute, which changed its name to Imevisión in 1985. Imevisión comprised not only Canal 13, now known as Red Nacional 13, but the former Televisión de la República Mexicana, with its XEIMT-TDT, and a new network known as Red Nacional 7 and broadcast in Mexico City by the brand-new XHIMT-TDT channel 7.
During the Imevisión years, Red Nacional 13 continued to broadcast commercial programming, although it featured some programs with a cultural focus, such as Temas de Garibay, Entre Amigos with Alejandro Aura, and several programs with journalist Jorge Saldaña.
In 1993, the administration of Carlos Salinas de Gortari auctioned off Imevisión and some other government-owned media ventures in various packages. Radio Televisión del Centro, headed by electronics store owner Ricardo Salinas Pliego, bought all of the TV stations. The result was the creation of Televisión Azteca, which took its name from the holding company created for the largest of the packages: the Red Nacional 13, including XHDF.
As part of the national virtual channel realignment of October 2016, Azteca Trece, including in Mexico City, moved from channel 13 to channel 1. The move allowed it to leapfrog Las Estrellas, its primary competitor, which remained on channel 2; it also ultimately led to the rename of the network as Azteca Uno effective January 1, 2018.
