[1] The core of the Canal 13 network was born in 1980 with the concession award of XHTVL-TV, analog channel 9 in Villahermosa, to Tele-Emisoras del Sureste, S.A. de C.V. (from which the name Telsusa is derived).
Tele-Emisoras was owned by Remigio Ángel González, a Guatemalan entrepreneur who would later accumulate media holdings elsewhere in Latin America, as well as radio station owner Francisco Javier Sánchez Campuzano and Manuel Efraín Abán Méndez, who had placed the winning application for the channel in 1979, beating out Jorge Kanahuati Gómez and Fernando Laurencio Pazos de la Torre.
[3] Despite González being born in Mexico, Telsusa was a small link in Albavisión, which grew to wield considerable national broadcasting—and political—power elsewhere in Latin America.
[5] González set his sights on expanding his Mexican holdings as early as 2008, when Proceso reported that he was eyeing the creation of a national television network if new TV stations were put out for bid.
[7] Activity remained mostly quiet on the new stations through 2018, with the exception of an agreement with the Sistema Público de Radiodifusión del Estado Mexicano to use SPR transmitter sites in Campeche, Xalapa and Mérida.
In September 2019, five more stations hit the air in the span of a week, covering Valladolid, Yucatán, Puebla, Campeche, Mérida and Ciudad del Carmen.
