San Diego's first television station was KFMB, which began broadcasting on May 16, 1949. Since the Federal Communications Commission (FCC) licensed seven television stations in Los Angeles, two VHF channels were available for San Diego because of its relative proximity to the larger city. In 1952, however, the FCC began licensing UHF channels, making it possible for cities such as San Diego to acquire more stations. Stations based in Mexico (with ITU prefixes of XE and XH) also serve the San Diego market. Television stations today include XHTJB 3 (Once TV), XETV 6 (CW), KFMB 8 (CBS), KGTV 10 (ABC), XEWT 12 (Televisa Regional), KPBS 15 (PBS), KBNT-CD 17 (Univision), XHTIT-TDT 21 (Azteca 7), XHJK-TDT 27 (Azteca 13), XHAS 33 (Telemundo), K35DG-D 35 (UCSD-TV), KDTF-LD 51 (Telefutura), KNSD 39 (NBC), KZSD-LP 41 (Azteca America), KSEX-CD 42 (Infomercials), XHBJ-TDT 45 (Gala TV), XHDTV 49 (MNTV), KUSI 51 (Independent), XHUAA-TDT 57 (Canal de las Estrellas), and KSWB-TV 69 (Fox).
