Exa FM's familiar orange branding and "Ponte Exa" slogan are a relatively recent addition to a Mexico City frequency that has been broadcasting since 1974. The station, now known on air as Exa FM 104.9, first signed on under the Stereorey consortium, the same group that brought FM radio to major Mexican cities including Monterrey.
From Stereo Best to FM Globo
The station's original identity was Stereo Best, under the callsign XHBST-FM, before shifting entirely into FM Globo, a format that cycled through romantic music, Spanish pop and contemporary hits over the years, according to the station's documented history. The callsign itself changed to XHMRD-FM on October 8, 1991, more than a decade before the frequency took on the identity most Mexico City listeners know today.
The Birth of the Orange Station
That final transformation came on January 1, 2000, when MVS Radio relaunched the frequency as Exa FM with a Top 40 CHR format, a name that nods to the network's habit of airing blocks of six consecutive songs without interruption. The callsign followed the rebrand, becoming XHEXA-FM to match. From that single Mexico City flagship, MVS built what is now the largest youth radio chain in the country, spreading the same orange branding and "La Estación Exacta" slogan to more than 70 stations across nine countries.
The Flagship Behind Dozens of Local Signals
Every regional Exa FM station, from Aguascalientes to Guatemala City, ultimately answers back to this Mexico City frequency's 2000 rebrand, even when local ownership and programming details differ city to city. The flagship still carries the format in its purest form: contemporary pop and pop rock hits in Spanish and English, aimed squarely at young listeners who have no memory of Stereo Best or FM Globo ever existing on this dial position.
