XEOY-AM

XEOY-AM is a radio station based in Mexico City on 1000 kHz. The station is owned by NRM Comunicaciones and simulcasts the programming of sister station XHMM-FM 100.1, with the adult contemporary format Stereo Cien. KNWN in Seattle, Washington, WMVP in Chicago, Illinois and XEOY-AM share Class A status of 1000 AM. XEOY was founded on February 10, 1941, by Ignacio Díaz Raygosa and Jose Iturbe Umantour; Raygosa was the grandson of former Mexican president Porfirio Díaz, while Umantour's grandfather was José Yves Limantour, the finance secretary for most of the Porfiriato. The first broadcast of XEOY-AM was the Ninth Symphony by Ludwig van Beethoven. In 1942 it was sold to Guillermo Salas Peyró, who gave the station its long-running name of "Radio Mil" (Radio Thousand), after its position on the dial. From XEOY-AM, Núcleo Radio Mil was formed, adding XEPH-AM 590, XEMX-AM 1380, XEBS-AM 1410 and XEUR-AM 1530 to the fold. From the 1950s onward, XEOY's format imitated that of XEW-AM, with general interest and family programming, as well as recorded music. August 28, 1955, saw XEOY branch out onto FM with XEOY-FM, originally on 100.5 MHz and later on 100.9 MHz. In 1961, that station became classical music "Estereomil"; it was swapped with XEBS-FM in 1967 to move to 89.7 MHz (now XEOYE-FM), while 100.9 FM is now XHSON-FM (still owned by NRM).
