It broadcasts on 94.9 FM and carries an urban music format known as Fiesta 94-9.
XEFM-AM 1010 received its concession in 1963 and was originally owned by José L. Bravo.
Despite this, it was part of the growing broadcast empire of Carlos Ferráez Matos, which also grew to include new television station XHFM-TV channel 2, one of the first affiliates of Televisión Independiente de México, in the decade.
On March 31, 2022, it dropped its "One FM" format of electronic music.
A new permanent format, Spanish urban as "Fiesta 94-9", debuted on May 1, 2022.
