==History== ===Concession, sign-on and early years=== On June 28, 1991, the Diario Oficial de la Federación announced that channel 40 in Mexico City was open to be an independent commercial television station. The new station would have its transmitter located on Cerro del Chiquihuite, and it would have an effective radiated power of 5,000 kW; a call sign of XHEXI-TV, never to be used on air, was also assigned at this time. The availability of a new television station in Mexico City, for the first time in decades, attracted high-powered media companies aspiring to enter the television business. Of 18 total applicants, 10 qualified for the concession for the new television station. Among the competitors were Francisco Aguirre Gómez of Grupo Radio Centro, Rafael Cutberto Navarro of Radio Cadena Nacional, Grupo Siete Comunicación, and other owners of radio stations.
