## History

XEX-FM signed on the air on October 1, 1975. It became the third FM station in the Radiópolis/Televisa Radio system. It carried an [adult contemporary](/source/Adult_contemporary) music sound as "Stereo 102", but most of its history has been marked by frequent format changes. In the early 1980s, it was "Radio Romántica", then "Estelar FM" (both with romantic music). That was followed in 1988, by a return to pop music in English and Spanish as "Estéreo 102".

It later was "Yo 102", a [contemporary hit radio](/source/Contemporary_hit_radio) format giving the station some ratings success. In 1994, it experimented with the name "[Kiss FM](/source/KISS-FM_(brand))", which failed to catch on. In 1996, after the brief return of Stereo 102, XEX-FM became "Vox FM".

In 2002, Televisa Radio and Spain's [PRISA](/source/PRISA) began a partnership. The two companies launched the "[Los 40](/source/Los_40) Principales" brand in Mexico, which was popular in Spain and other Latin American countries. Televisa Radio and [Grupo Radiorama](/source/Grupo_Radiorama) signed an agreement, allowing the much larger Radiorama to [syndicate](/source/Radio_syndication) the Los 40 Principales format to its stations for wider coverage across Mexico.
