The original XEWA in San Luis Potosí received its concession on December 2, 1948, one of a string of repeaters of XEW-AM 900 Mexico City authorized in the late 1940s.

In May 1961, a second station, initially with call sign XEWM-AM, was licensed to operate in Monterrey, Nuevo León, in order to provide daytime XEW service and an improved nighttime signal there; the call letters soon were changed to XEWA-AM to match the co-channel San Luis station.

Broadcasting from Monterrey but heard in both cities, Súper Estelar was programmed by Multimedios Estrellas de Oro and served as one of Mexico's pioneering grupera stations.

The end of Súper Estelar made way for a flip to the Ke Buena format and operation by Televisa again, which lasted into the late 1990s when the station began repeating XEW again, now known as "Cadena W Azul y Plata" and later as "W Radio".

XEWA Monterrey flipped to Los 40 Principales in September 2014, matching the San Luis station though it remained separately programmed and directly run by Televisa Radio.
