XERC-FM signed on in 1974, more than a decade after receiving its concession on July 26, 1963, alongside the two other FM stations built by Radio Centro, and was known as "Radio Hits", airing current music in English. The original concession was held by Radio Popular de México, S.A. but was sold to Radio Central de la Provincia in 1975. In August 1988, it changed its format and name to "Stereo 97.7" and now featured mostly Spanish-language pop, becoming a more general CHR station with music both in Spanish and English during the following years. The station's primary innovation in terms of format was the "three-by-three" (de tres por tres) song arrangement, in a time where usually only a song was aired before and after a commercial break. This arrangement was rapidly copied by other stations and even expanded (for example, airing blocks of five or six consecutive songs), and is practically commonplace in all musical stations nowadays. From 1989 until 1993, it was Mexico City's most popular radio station, being surpassed by the grupera "Sonido Z" (now "La Z") at XEQR-FM.
By the late 2000s, the station's name was simplified to just "97-7".
On November 7, 2016, the station was rebranded as "Radio Centro 97.7", with its format switching to Spanish-language music only.
