[2] After moving in a rock direction for years, in August 1967, the station became rock-formatted "La Pantera" (The Panther).
In 1987, the station became Spanish modern rock-formatted Espacio 59, only to go back to 1960s and 1970s rock in December 1989.
1995 saw the creation of Sabrosita, which moved to XHSON-FM 100.9 in 1999 to make way for a return of La Pantera to 590.
In 2004, with the creation of the current Beat 100.9 dance music format, Sabrosita returned to 590 AM.
NRM ceased separate programming of XEBS-AM 1410 on December 1, 2022, and brought the two stations together as a simulcast known as Sabrosita 590 y 1410.
