===XEW-AM===
XEW began regular broadcasts at 20:00 CST on {{Start date and age|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&nbsp;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.{{citation needed|date=October 2021}} On February 10, 2016, XEW-AM was approved to relocate its transmitter to a site in La Magdalena Atlicpac in [[La Paz, State of Mexico|La Paz]].  With the move, the power was reduced to 100,000 watts, still among North America's most powerful AM stations.{{r|tecnica}}

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, whose radio unit still owns XEW-AM.  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-TV|XEW television]], all of them affiliated at one time or another with Televisa.{{citation needed|date=March 2015}}

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.{{citation needed|date=March 2015}}
