 Multimedios was founded in 1940 when Jesús Dionisio González acquired Monterrey radio station XEX, where he had formerly worked, for 12,500 pesos.After World War II, the Mexican government requested the XEX callsign to build a national clear-channel station, and González selected the XEAW call letters, which had formerly belonged to a station in Reynosa, Tamaulipas.In the 1950s, the group became known as "Organización Estrellas de Oro" ("Gold Stars Organization"), which in the 1990s changed its name to "Multimedios Estrellas de Oro" and later Grupo Multimedios.
