[2] The transmitter is on Avenida Rio Bravo, in Los Reyes Acaquilpan, just east of Mexico City.

During the 1940s, XEX was a network affiliate of the Mutual Broadcasting System as its Latin American flagship station.

[3] Its sister stations were also flagships of Latin American branches of competing radio networks, XEW-AM with NBC and XEQ-AM with CBS.

In 2003, the format settled at XEX and was known as Estadio W until 2012 when it adopted the branding "TDW," in reference to Televisa's sports cable channel "TDN."

XEX moved its transmitter in 2016 to a new site in Los Reyes Acaquilpan, La Paz Municipality, State of Mexico.
