 Some Mexican border stations (such as the former English-language ABC/Fox/CW affiliate XETV-TDT in Tijuana) who formerly maintained affiliations with U.S.-based English or Spanish networks, but mainly targeted their programming at their American border city (more than the Mexican metropolitan area that they are based in or merely licensed to).Although the English-language programming model in the U.S. traditionally relies on the network and its stations handling programming responsibilities, Spanish language networks handle most of the responsibility for programming, while affiliates are limited to breakaways from the network feed to provide local news, public affairs and/or entertainment programming as well as local advertising.As such, all Spanish language networks primarily available on broadcast TV operate national feeds that are distributed to cable and satellite providers in markets without a local affiliate.
