XHDY's concession was awarded on June 19, 1984, to José de Jesús Partida Villanueva, a businessman with connections to Televisa. In 1993, the station's concession was transferred to Comunicación del Sureste. XHDY maintained a partnership with Televisa and carried programming from its channel 9 network and FOROtv, and as a Televisa partner, Comunicación del Sureste is defined as within the "preponderant economic agent" in broadcasting for regulatory purposes. In 2014, XHDY sourced 72 percent of its broadcast day from Televisa. In 2017, simultaneous events prompted XHDY to disaffiliate from Televisa. One was the unwinding of many local relationships as Televisa began to multiplex Gala TV on subchannels of its own TV stations in some areas of the country where said programming had been broadcast on a local station, including Tuxtla Gutiérrez and San Cristóbal de las Casas. Another was the successful participation of Telsusa Televisión México, S.A. de C.V., a company also controlled by Remigio Ángel González, in the IFT-6 television station auction, in which it acquired TV stations in twelve cities primarily in southern and eastern Mexico. On October 18, 2018, XHDY and its sister stations moved to virtual channel 13.
Programming
XHDY's local program output includes local newscasts, branded as 13 Noticias Chiapas, and a morning magazine and talk show, Giros. Outside of local programming, XHDY, its Chiapas sister stationXHGK, and its Tabasco sister station XHTVL/XHTOE air almost all of the same programming. Since disaffiliating from Televisa, most of XHDY's entertainment programming has come from Albavisión television channels in other countries, such as ' and the Argentina version of Combate or been acquired on the international market, such as the Colombian telenovela '. Weekends are taken up by older Mexican movies.
