Under FCC regulations, San Diego is the largest media market in the United States that is legally unable to support a duopoly between two full-power television stations; by law, duopolies are not allowed in any U.S. market with fewer than nine full-power stations and once a duopoly is formed, there must be eight unique station owners that remain in a single market. The California side of the market does not fall under either requirement as there are only seven full-power stations in that part of the San Diego–Tijuana metropolitan area. Though the E. W. Scripps Company owns KGTV and KZSD-LP, they are not considered a duopoly under the FCC's legal definition as common ownership between full-power and low-power television stations in the same market is permitted regardless to the number of stations licensed to the area. The Mexico-licensed stations in the market are not subject to the duopoly rules as two or more full-power television stations are allowed to be owned by the same company under Mexican telecommunications law (Grupo Televisa owns three stations: XETV-TV, XHUAA-TV and XHWT-TV, while Entravision Communications and TV Azteca each own two stations: XHAS-TV and XHDTV-TV and XHJK-TV and XHTIT-TV, respectively).
