Fox has just about the same household reach percentage as the Big Three, and is therefore often considered a peer to ABC, CBS, and NBC since it has also achieved equal or better ratings since the late 1990s; as of 2019, it also programs the equivalent amount of sports programming as the Big Three.
Additionally, Televisa, which distributes programming to Univision in the United States, operates in Mexico, but the company's networks (Canal de las Estrellas, Canal 5 and Nueve) have certain stations which can be received in parts of the U.S. located along and near the Mexican border, and likewise with the American networks have affiliates located or receivable in Mexican border cities.
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).
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.
Several religious networks allow their broadcast affiliates to carry their programming out-of-pattern through clearance arrangements, notably TBN, 3ABN, Hope Channel and World Harvest Television.
