 Laredo was just barely large enough for three television stations, and its close proximity to the Mexican border limited its potential audience.Prior to the launch of KLDO, KGNS-TV aired some of ABC's network programs as a secondary affiliate.In addition, the network's affiliates in markets adjacent to Laredo (KIII in Corpus Christi and KSAT-TV in San Antonio) became available on cable systems in the Laredo market a few years prior to the station's sign-on.
