The station signed on for the first time on September 4, 1994, as XHFOX-TV (changed from the original XHRTA-TV before launch), broadcasting programming from the Fox network for Texas' Rio Grande Valley; prior to XHFOX's sign-on and after its switch to Las Estrellas in 2002, viewers in the valley (including McAllen) received their Fox programs on cable via the national Foxnet service. In 2001, its final year as a Fox affiliate, XHFOX broadcast a local newscast at 9:00 p.m. produced by KRGV-TV.[2]
In 2002, XHFOX disaffiliated from Fox and became XHTAM-TV, largely rebroadcasting programming from Las Estrellas.[2] The Fox affiliation was carried over to XHRIO-TV from 2005 to 2012; Fox programming today can be seen on KFXV.
