History XHMM signed on in the early 1970s as "Radio Maranatha" after receiving its concession on June 8, 1965. In 1977, the station was acquired by SOMER (Sociedad Mexicana de la Radio), which on July 17 of that year relaunched it as "Stereo Cien." It began airing adult contemporary music in English as well as news and talk programs in Spanish. Since its inception, the station's logo has featured the image of a dolphin, and a dolphin cry is used as an on-air ID. In 1995, SOMER signed a deal with Núcleo Radio Mil to operate and comercially manage the station. SOMER owner Edilberto Huesca would eventually take control of NRM from its founder Guillermo Salas Peyró.
XHMM carries adult contemporary music from the 1980s to the present, and the "Enfoque" newscasts on weekdays. Its online stream plays commercial-free music during the timeslots in which the over-the-air station airs the newscasts, which can be heard on a separate stream.
On June 7, 2021, sister station XEOY-AM 1000 became a full-time simulcast of XHMM.
