History

XERC-FM signed on in 1974, alongside the two other FM stations built by Radio Centro, and was known as "Radio Hits", airing current music in English. 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".
