Public broadcasting in Oaxaca began in the early 1980s under Governor
Pedro Vásquez Colmenares, with the insertion of local opt-outs into the programming of the Canal 7 network of
Imevisión. Original output consisted entirely of plays staged for television by the Compañía Teatral Palo Bravo, as the state lacked production resources. In 1988, the Instituto Oaxaqueño de Radio y Televisión (IORTV) was established. On March 21, 1989, under the direction of
Virgilio Caballero Pedraza, IORTV was reorganized as Radio y Televisión de Oaxaca (RTO). It adopted its present name in 1993. The CORTV facilities were seized on August 1, 2006, during
protests in the state after CORTV officials refused a women's group air time to make social demands. The takeover was ended on August 20 when the transmitters on Cerro del Fortín were shot at, damaging them and taking CORTV radio and television off the air. ==Television transmitters==
