KABC-TV (channel 7) is a television station in Los Angeles, California, United States, serving as the West Coast flagship of the ABC network. Owned and operated by the network's ABC Owned Television Stations division, the station maintains studios in the Grand Central Business Centre of Glendale, and its transmitter is located on Mount Wilson. History Channel 7 first signed on the air under the call sign KECA-TV on September 16, 1949. It was the last television station licensed to Los Angeles operating on the VHF band to debut and the last of ABC's five original owned-and-operated stations to make its debut, after San Francisco's KGO-TV, which signed on four months earlier. It was also the last of the Los Angeles "classic seven" TV stations which were originally on the VHF dial, prior to the 2009 digital conversions. (No other stations debuted in Los Angeles until 1962, when the first two UHF Los Angeles stations launched (KIIX [now KWHY-TV] and KMEX-TV, channels 22 and 34, respectively). The station's call sign was named after Los Angeles broadcasting pioneer Earle C. Anthony, whose initials were also present on channel 7's then-sister radio station, KECA (790 AM, now KABC). On February 1, 1954, KECA-TV changed its call sign to KABC-TV. Originally, KABC-TV was located at the ABC Television Center, now called The Prospect Studios, on Prospect Avenue in the Los Feliz neighborhood of Los Angeles, east of Hollywood. In 2000, KABC-TV moved to nearby Glendale into a new state-of-the-art facility designed by César Pelli, as part of the Disney Grand Central Creative Campus (GC3), in the Grand Central Business Centre on the site of the former Grand Central Airport. The station is currently located east (along the corridor of the Los Angeles River and State Route 134) of ABC's West Coast headquarters on the Walt Disney Studios lot in Burbank. KABC-TV has used the Circle 7 logo since 1962 (the same year ABC created and implemented its current logo) and augmented its bottom left quadrant with the ABC network logo in 1997. The station's news anchors and reporters wear Circle 7 lapel pins when they appear on camera, a practice that had once been standard at each of the original five ABC-owned stations. On February 4, 2006, KABC-TV became the first television station in the state of California to broadcast its local newscasts in high definition using HD cameras in the studio and debuted
