launched KFMB-DT2's run as a CW affiliate three minutes later. By Dunning's estimate, about 150 full-time, part-time, and freelance staffers were laid off between the closure of the news department on March 31 and the corporate shutdown. In addition to ending channel 6's affiliation with The CW three months earlier than scheduled, the closure of Bay City Television concluded XETV's 64-year history of serving San Diego with English-language programming; the move left MyNetworkTV affiliate XHDTV-TDT as the sole Mexican-licensed station providing English-language programming to the San Diego market until just over a year later in September 2018, when it was replaced with Milenio Televisión. Special broadcast authority Because XETV-TDT is licensed to Tijuana by the Mexican government, it is not covered under the FCC's must carry rules. This means that local cable providers are not required to carry XETV-TDT, even if the television station requests to be carried under this provision. As an English-language station XETV had been carried by Cox Communications, Charter Spectrum and AT&T U-verse in San Diego, all on channel 6. KFMB-TV's "The CW San Diego" has replaced XETV on the American cable systems, as well as satellite television providers DirecTV and Dish Network. XETV is carried by all Mexican cable systems in its coverage area, as carriage of local broadcast stations is mandated by the Federal Telecommunications Institute (IFT). While XETV's primary programming feed had been almost entirely in English from the 1950s until 2017, XETV also complied with Mexican broadcasting laws, which include clauses that are different from those in the United States. It identified every 30 minutes; started its legal broadcast day with the Mexican national anthem "El Himno Nacional Mexicano" at 5:00 a.m. six days a week and 6:00 a.m. on Sundays; and it aired public service announcements and political advertising required of all Mexican stations. At sign-on, it featured a technical disclaimer which had been read in Spanish and English dating back to channel 6's days as a Fox affiliate, and it also played the national anthem of the United States, "The Star-Spangled Banner", prior to the disclaimer until around March 2015. XETV's production operations were based in the United States from the mid-1990s until Bay City Television's closure. The station's production, news and sales operations were owned by Bay City; Televisa controls the master control and transmitter facility on Mount San Antonio in Tijuana.
