It carries the Arroba FM pop format from Grupo Radiorama.

It began broadcasting later that year as part of Corporación Puebla de Radiodifusión, a subsidiary company of Grupo ACIR; the concession was held by Alberto Guilbot Serros until ACIR purchased it outright in 1998.

At the beginning of the 2000s, it changed its format to Spanish adult contemporary as Inolvidable; in 2004, it returned to ranchera as "Bonita".

In 2009, Grupo ACIR sold a group of its stations, located throughout Mexico, to Radiorama, including XEZAR-AM.

This was Radiorama's first station in the Puebla market, and the company opted to lease it out to Grupo Oro.
