KTTV (channel 11) is a television station in Los Angeles, California, United States. It is the West Coast flagship station of the Fox television network, owned and operated through its Fox Television Stations division. Under common ownership with MyNetworkTV outlet KCOP-TV (channel 13), the two stations share studios at the Fox Television Center on South Bundy Drive in West Los Angeles; KTTV's transmitter is located atop Mount Wilson.

KTTV's origins can be traced to 1947, when the station's license and construction permit was secured by the Times Mirror Company, publishers of the Los Angeles Times. It was one of five licenses that were granted simultaneously by the Federal Communications Commission (FCC) to parties interested in expanding commercial television in Los Angeles. In 1948, CBS, which owned KNX radio, purchased a 49% interest in the station and assisted in completing its construction in exchange for making channel 11 the network's Los Angeles television outlet. KTTV began operations on January 1, 1949, and was operated initially by KTTV, Incorporated, the Times/CBS-owned holding company. The station's first telecast was the Tournament of Roses Parade, which channel 11 would air every New Year's Day until 1995.

In May 1950, Times-Mirror purchased the Nassour Studios – a large motion picture facility on Sunset Boulevard in Hollywood, and centralized KTTV's operations there. CBS did not join Times-Mirror in the purchase; at the time its West Coast production facilities were based at Columbia Square, with its CBS Television City facility in the planning stages. KTTV converted the Nassour Studios into a major production house for television, producing programs locally and for the emerging syndication market. Prior to the move, KTTV operated out of several different facilities, including the former headquarters of Capitol Records (which was later the longtime home of KHJ radio and what is now KCAL-TV) on Melrose Avenue.

Later in 1950, CBS chose to acquire its own station in Los Angeles – pioneer station KTSL (channel 2, renamed KNXT and now KCBS-TV) – which was being spun off by the Don Lee Broadcasting System as a result of its sale to General Tire and Rubber. The KTSL purchase forced CBS to divest its interest in KTTV due to FCC rules in effect at the time that barred the common ownership of two television stations in the same media market; the Los Angeles Times would regain full ownership of channel 11 when the sales were finalized on January 1, 1951. KTTV's relationship with CBS ended after exactly two years as the network moved its programming to KTSL. A few months later, channel 11 agreed to become the new Los Angeles outlet of the DuMont Television Network, which had been affiliated with KTSL, and before that KTLA (channel 5).

In 1954, DuMont moved its programming to KHJ-TV (channel 9, now KCAL-TV), and KTTV became an independent station. During the late 1950s, the station was also briefly affiliated with the NTA Film Network. In 1958, channel 11 scored an advantage against its rivals when it became the television home of the Los Angeles Dodgers baseball team, which had relocated from Brooklyn, New York, that year. For the first 11 years and at the request of the team, KTTV's Dodger telecasts were limited to road games against the archrival San Francisco Giants. Eventually, the number of Dodger games broadcast on the station increased and the home game blackout was lifted; the relationship between KTTV and the Dodgers would last until the end of the 1992 season.

The show Confidential File on KTTV covered the 1962 convention of the Daughters of Bilitis and aired after Confidential File became syndicated nationally; this was probably the first American national broadcast that specifically covered lesbianism.

The Times-Mirror Company sold the station to Metromedia in 1963. Later that year, Metromedia purchased KLAC (570 AM) and the original KLAC-FM (102.7 FM, now KIIS-FM), giving channel 11 sister stations on the radio dial. Metromedia would later engineer a trade of FM frequencies, resulting in KLAC-FM moving to 94.7 FM (later to become KMET, now KTWV) in 1965.

By the 1970s, KTTV offered a traditional general entertainment schedule common among independent stations at the time, consisting of children's programs, off-network reruns, sports programming and old movies, along with a 10 p.m. newscast. Some of the staff members in the earlier 1970s were John Jones, Sales Manager; George Putnam, news anchorman; Putnam's co-anchor Hal Fishman; Ken Jones, first black on-air TV newsman in L.A.; Tom Kelly, TV sports reporter; Terry Mayo, noontime news; and Rona Barrett, who taped her syndicated gossip report at KTTV, written by assistant Barbara Sternig. With the evolution of cable television, KTTV became a regional superstation. Thanks to its Dodgers broadcasts and round-the-clock programming, KTTV was seen on various cable systems across the Western United States during the 1970s and into the 1980s, as far east as El Paso, Texas. KTLA, with its Angels broadcasts, also became a superstation. KTTV and KTLA were seen on most Southern and Central California cable systems, with KHJ-TV and KCOP also getting carried outside Los Angeles to a lesser extent.
