KNBC, channel 4, is an owned-and-operated television station of the NBC Television Network, licensed to Los Angeles, California, USA. KNBC's studios and offices are located within the NBC Studios complex in Burbank, California, and its transmitter is located on Mount Wilson. In the few areas of the western United States where viewers cannot receive NBC programs over-the-air, KNBC is available on satellite to subscribers of DirecTV.

KNBC is one of two NBCUniversal-owned television stations in Los Angeles; the other is Telemundo outlet KVEA (channel 52).

Channel 4 first went on the air on January 16, 1949, as KNBH (for NBC Hollywood). It was the penultimate VHF station of Los Angeles to debut, and the last of the five original NBC-owned stations to sign on. Unlike the other four, KNBH was the only NBC-owned television station which did not benefit from having a sister station on radio. NBC Radio had long been affiliated with KFI in Los Angeles, and that relationship extended into television in August 1948 when KFI-TV (channel 9, now KCAL-TV) was launched as an NBC television affiliate. When KNBH signed on, KFI-TV was forced to relinquish its rights to NBC programming, though KFI radio retained its relationship with the network.

Paul Moyer (born August 1, 1941) is a veteran television news broadcaster in Southern California. He co-anchored the 5 PM and 11 PM weekday editions of KNBC-TV's Channel 4 News with Colleen Williams. Moyer has worked primarily in the two major television markets—New York and Los Angeles—in addition to briefly working on network newscasts. Moyer was Los Angeles' longest-running news anchor following the death of KTLA anchor Hal Fishman on August 7, 2007. He is married and has four children, Elise, Paul, Dylan and Kyle.

On April 1, 2009, KNBC's Colleen Williams announced, during the evening newscast, that Moyer had decided to retire after 25 years at the station. Moyer's salary was estimated^{[by whom?]} at more than $3 million a year at his time of retirement.

Moyer was born in Los Angeles, California. He attended Torrance High School and the University of Arizona (class of 1964), and tried out for the Pittsburgh Pirates, before beginning a broadcasting career. He served positions at KTIV in Sioux City, Iowa, WMBD-TV and WMBD radio in Peoria, Illinois, KTVI in St. Louis, KDKA-TV and KDKA radio in Pittsburgh, and then WCBS-TV in New York City before returning to Los Angeles and joining KNBC in March 1972 as reporter and weekend anchor. The KNBC Newservice, as it was known, then featured Jess Marlow, Tom Snyder, and Tom Brokaw as the main nightly anchors and was the first serious competition in the local news ratings against KNXT's The Big News with Jerry Dunphy. Moyer soon moved to the 11 p.m. newscast in July 1973 and to the 6 p.m. newscast in December 1974 with the respective departures of Brokaw and Snyder (the latter instance followed the addition of John Schubeck to the late news).

Roy Harold Scherer, Jr., later Roy Harold Fitzgerald (November 17, 1925 – October 2, 1985), known professionally as Rock Hudson, was an American film and television actor, most recognized as a romantic leading man during the 1950s and 1960s, most notably in Magnificent Obsession (1954), Giant (1956) and several popular comedies with Doris Day. Later roles included the leads in Ice Station Zebra and the popular television series McMillan & Wife along with a role in the hugely successful series Dynasty.

Hudson was voted "Star of the Year", "Favorite Leading Man", and similar titles by numerous movie magazines. The 6 ft 5 in (1.96 m) tall actor was one of the most popular and well-known movie stars of the time. He completed nearly 70 motion pictures and starred in several television productions during a career that spanned over four decades.

Hudson died in 1985, being the first major celebrity to die from an AIDS-related illness.

Hudson was born Roy Harold Scherer, Jr., in Winnetka, Illinois, the only child of Katherine Wood (of English and Irish descent), a telephone operator, and Roy Harold Scherer, Sr., (of German and Swiss descent) an auto mechanic who abandoned the family during the depths of the Great Depression. His mother remarried and his stepfather Wallace "Wally" Fitzgerald adopted him, changing his last name to Fitzgerald. Hudson's years at New Trier High School were unremarkable. He sang in the school's glee club and was remembered as a shy boy who delivered newspapers, ran errands and worked as a golf caddy.
