XEW-AM XEW began regular broadcasts at 20:00 CST on September 18, 1930. Broadcasting from a room (later to become a proper studio) at the Olympia Cinema on 16 September Street in Mexico City, it initially was powered at only 5,000 watts. This was increased to 50,000 watts by 1934. With the installation of a new
transmitter, the power became 250 kW by 1935 and remained there for more than 80 years. For much of its history, XEW-AM was the most powerful AM radio station in North America. On February 10, 2016, XEW-AM was approved to relocate its transmitter to a site in La Magdalena Atlicpac in
La Paz. With the move, the power was reduced to 100,000 watts, still among North America's most powerful AM stations. XEW was the first Mexico City station in
Emilio Azcarraga Vidaurreta's
Chain of the Americas. It was the forerunner to today's
Televisa network, which still owned XEW-AM until the sale of their radio unit in 2020. XEW-AM originally was affiliated with the
NBC Red Network and the
NBC Blue Network. Its future sister stations would take affiliation with rival networks,
XEQ-AM with
CBS and
XEX-AM with the
Mutual Broadcasting System. As radio in Mexico evolved with the country's growth and more radio stations signed on, XEW-AM became flagship to the country's largest radio network. Several radio and television stations have derived their call signs from XEW radio and
XEW television, all of them affiliated at one time or another with Televisa. In the United States, the call letters for
KXEW, a commercial AM radio station in
Tucson, Arizona, were a tribute to 900 XEW. That station was owned by Pan American Radio Corporation and went on the air May 10, 1963. The call sign was chosen by its president and CEO, J. Carlos McCormick, because of his admiration of Azcarraga, whom he had met as a teenager during a 1950 visit to Mexico City.
XEW-FM The FM frequency, 96.9, received its concession on April 28, 1962; it was not launched until the 1970s, and by the end of that decade, it carried a
disco format. By 1981, it had changed to "Rock Stereo". On September 9, 1985, it was renamed "WFM" with an English rock and pop format, being the direct competition of
XHSON-FM (then known as "Rock 101"). Among the DJs that conformed the station were
Alejandro González Iñárritu, Martha Debayle and Charo Fernández. After 14 years, in 1999, the station changed its name and format to "W Radical." It was directed by the former head of "Rock 101", Luis Gerardo Salas, airing
electronic music and
eurodance. By 2001, it returned to its former WFM format with the slogan "Frecuencia Adictiva." In late 2002, after the association of Televisa Radio and PRISA, management decided to simulcast the same programming on AM and FM. Thus XEW-FM became a news and talk outlet, albeit musical programming can still be heard on overnights and weekends when live sports broadcasts are not scheduled. ==Personalities==
