It is owned by Sistema Tele Yucatán, S.A. de C.V., a company wholly owned by the government of the State of Yucatán, with a schedule of primarily local programs including news, sports, culture and entertainment.

While channel 13 had periodically broadcast the Olympics in 1968,[1] XHST-TV formally signed on February 27, 1970, transmitting a black-and-white signal.

However, the station's ambitious plans were crippled in 1974, when the federal government, acting on behalf of state financier SOMEX, seized its assets; in 1975, most other Tele-Cadena Mexicana stations were expropriated and added to the state-owned Canal 13 network from Mexico City.

In 1981, XHST found its savior: the government of Yucatán, which bought the station from SOMEX and immediately set out to modernize and expand it.

In 2015, XHST received authorization to operate digital channel 28 at 100 kW.
