Radio Oaxaca, S.A., the owner of XEOA (570 AM), received the concession for XHBO-TV on channel 3 on October 21, 1988.
XHBO moved to channel 4 in 2001—which enabled an OPMA transmitter to start up in 2010—and removed almost all local program production.
Televisa output, which later came from the Gala TV/Nu9ve network, made up 87 percent of the station's broadcast day, resulting in the station being defined as within the "preponderant economic agent" in broadcasting for regulatory purposes; 80 percent of its programming in 2014 was sourced from the company.
[3] Televisa programming was removed from XHBO in 2018 after the company multiplexed Nu9ve on its own transmitter in Oaxaca.
At disaffiliation, it switched to output from La Octava in Mexico City.
