XEDA-AM

XEDA-AM was a radio station on 1290 AM in Mexico City, Mexico. It began operations on December 3, 1936, and it was the flagship station of Radio S.A., with a news and talk format. As of May 31, 2015 the station has now off the air.

History
The first concession for XEDA was awarded to Augusto García Díaz, for a station on 680 kHz. Not long after it moved to its current 1290 kHz frequency. In 1953, the station was bought by Publicistas, S.A., the business of Guillermo Morales Blumenkron, which also obtained a concession for XEDA-FM (now separately owned). The concessionaire was not changed for another 59 years, but in 1991, the year in which it changed its name to Corazón Latino, using boleros and Caribbean rhythms in its programming. In 1992, it changed its format again and was called Rock N' Radio, with catalog music in English. This was maintained until December 1993, when the XEDA-AM station was sold by Grupo Imagen to Radio S.A and became Radio Trece again with new news/talk format.

While Radio Trece programming continued online, the AM radio station was turned off on May 31, 2015. Radio S.A. cited the unprofitability of AM radio in its decision. Radio S.A. also cited a lack of official advertising budget for AM radio stations in Mexico City, the unavailability of the AM band on newer radios, and poor sound quality, in its decision; it noted that it had to lay off 150 people "for being obligated to operate with obsolete technology". XEDA's concession was not renewed and expired on July 3, 2016.
