XHDF started as an independent broadcaster in July 1968. In 1972 it became a state-owned station after it was expropriated. In 1983 it became one of three stations originally owned and operated by the newly formed Imevisión, the Mexican public broadcaster (XHIMT-TV and XEIMT-TV were the others). In 1993, it and XHIMT became part of the new commercial Grupo Salinas, when the Mexican government dissolved Imevisión and sold most of its assets.
On December 17, 2015, XHDF and other television stations in Mexico City shut off their analog signals.
Azteca 13 Internacional
The network also operates an international version of XHDF, Azteca 13 Internacional, reaching 13 countries in Central and South America. On July 15, 2004, the Canadian Radio-television and Telecommunications Commission (CRTC) denied a request for Azteca 13 Internacional to be broadcast via digital cable and satellite. However, a second subsequent request was approved on January 20, 2006. The channel is available in Canada on Rogers Digital Cable and Vidéotron.
