KNBC, virtual channel 4 (UHF digital channel 36), is an NBC owned-and-operated television station located in Los Angeles, California, United States. The station is owned by the NBC Owned Television Stations subsidiary of NBCUniversal as part of a duopoly with Corona-licensed Telemundo owned-and-operated station KVEA (channel 52). KNBC's studios and offices are located in the Universal Studios Hollywood backlot, and its transmitter is located on Mount Wilson.

In the few areas of the western United States where an NBC station is not receivable over-the-air, KNBC is available on satellite television through DirecTV.

History

NBC Studios in Burbank, California, 1978.

Channel 4 first went on the air as KNBH (standing for "NBC Hollywood") on January 16, 1949. It was the penultimate VHF station in Los Angeles to debut, and the last of NBC's five original owned-and-operated stations to sign on. Unlike the other four, KNBH was the only NBC-owned television station that did not benefit from having a sister radio station. The NBC Radio Network had long been affiliated with KFI in Los Angeles, though that relationship did not extend into television in August 1948 when KFI-TV (channel 9, now KCAL-TV) signed on the air. When KNBH signed on, it marked the debut of NBC programs on the West Coast.

The station changed its callsign to KRCA (for NBC's then-parent company, the Radio Corporation of America) on October 18, 1954. The call letters were changed again on November 11, 1962, when NBC moved the KNBC identity from its San Francisco radio station (which became KNBR) and applied it to channel 4 in Los Angeles.

Channel 4 originally broadcast from the NBC Radio City Studios on Sunset Boulevard and Vine Street in Hollywood. In November 1962, the station relocated to the network's color broadcast studio facility in suburban Burbank. NBC Color City, as it was then known, had been in operation since March 1955, and was at least four to five times larger than Radio City, and could easily accommodate KNBC's locally produced studio programming. NBC Radio's West Coast operations eventually followed channel 4 to Burbank not too long after.

The Brokaw News Center, new location at the Universal lot, 2015

On October 11, 2007, NBCUniversal announced that it would put its Burbank studios up for sale and construct a new, all-digital facility near the Universal Studios backlot in Universal City, in an effort to merge all of NBCUniversal's West Coast operations into one area. As a result, KNBC, KVEA and NBC News' Los Angeles bureau moved to a new digital facility on the Universal lot formerly occupied by Technicolor SA. The studio opened on February 1, 2014. Shortly thereafter, NBCUniversal named the new broadcast center in honor of former KNBC and NBC News anchor/reporter Tom Brokaw, christened the Brokaw News Center.

In fall 2007 with digital broadcast roll out, the station began broadcasting a 24/7 newschannel News Raw on a subchannel. On January 16, 2009, KNBC celebrated its 60th anniversary with an hour-long tribute to the station, featuring past and present anchors, hosts, other popular on-air staff, and major news stories. KNBC and its other NBC owned-and-operated stations introduced a new layout for their websites in July 2009.

Digital television

Digital channels

The station's digital channel is multiplexed:

Channel	Video	Aspect	PSIP Short Name	Programming
4.1	1080i	16:9	NBC-4LA	Main KNBC programming / NBC
4.2	480i		COZI-TV	Cozi TV

KNBC also maintains a Mobile DTV feed of subchannel 4.1, labelled "KNBC-4.1", broadcasting at 1.83 Mbit/s.

On January 1, 2012, Universal Sports transitioned into a cable- and satellite-exclusive service, causing its affiliates (such as KNBC) to replace the network and remove the channel from their digital signals entirely, with KNBC deleting digital subchannel 4.4 (which also carried NBC Weather Plus from its November 15, 2004 launch to November 30, 2008) as result of the loss of Universal Sports.

NBC California Nonstop

Logo for NBC California Nonstop.

KNBC operated NBC California Nonstop, a collaboration between KNBC and two other NBC-owned stations in California (KNSD in San Diego and KNTV in San Jose) which launched on May 3, 2011 and replaced programming from NBC Plus on the second digital subchannels of all three stations. In the case of KNBC, it was the second news-oriented digital channel operated by the station, as digital channel 4.2 featured a rolling news format under the name NewsRaw (which moved from digital channel 4.4 upon Weather Plus' December 1, 2008 shutdown), prior to the launch of California Nonstop. Each station produced a local newscast at 7 p.m. that was tailored to their respective market. For the Los Angeles feed of the channel, Colleen Williams anchored the hour-long Nonstop News LA. NBC California Nonstop ended on December 20, 2012 when Cozi TV was launched.

Analog-to-digital conversion

KNBC shut down its analog signal, over VHF channel 4, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition UHF channel 36, using PSIP to display KNBC's virtual channel as 4 on digital television receivers. Since the station qualified for the nightlight clause in the DTV Delay Act, it was required to keep its analog signal on for two weeks from June 12 to 26, 2009 to inform viewers of the digital television transition, consisting of a loop of digital transition public service announcements, while the digital channel was used for normal programming.

Community Affairs

Current studio building shared by KNBC and KVEA

KNBC has a legacy of participating in the community. The station supports many social causes including health and wellness, the environment, diversity and supports under-served populations like the homeless, veterans, at-risk youth and women’s issues. KNBC has been recognized by many nonprofit organizations for its community work, and has partnerships with several prominent organizations including the L.A. Alliance of Boys & Girls Clubs, Court Appointed Special Advocates Los Angeles, California Community Foundation, American Red Cross Los Angeles, March of Dimes, American Heart Association, American Cancer Society, Hispanic Scholarship Foundation and others. The station also produces a news series called “Life Connected” which airs Sundays during the News at 11 p.m. and repeats on Mondays during the News at Noon. Life Connected tells stories of meaningful connections between individuals, and celebrates the diverse communities that make up Southern California. The station launched the “NBC4 Life Connected Award” to further spotlight these individuals at community events.

Syndicated programming

Syndicated programming seen on KNBC includes Steve Harvey and The Ellen DeGeneres Show. KNBC is the flagship station for Extra and Access Hollywood (and its live counterpart) which is produced by KNBC, both of which also air on KNBC and other NBC owned-and-operated stations. As of September 2016, KNBC is one of five NBC-owned stations that distribute programming either nationally or regionally (along with KNTV, WNBC, WCAU, WVIT and WTVJ).

News operation

As of 2016, KNBC broadcasts 39 hours of locally produced newscasts each week (with 6 ½ hours on weekdays, 3 hours on Saturdays and 3 ½ hours on Sundays). The station's newscasts has historically more of a "serious" tone covering issues (such as politics, government, education and the economy) than other Los Angeles area newscasts. In 2010, the Norman Lear Center at the University of Southern California found KNBC to have the least coverage of crime and the second-highest coverage of local government and sports and weather, compared to other Los Angeles stations. As part of a 2012 investment by parent company Comcast, KNBC's newscasts added 18 employees and produced more enterprise reporting.

The station runs a special hour-long newscast on Sunday nights following the Fred Roggin-hosted sports-themed game show The Challenge, during the NFL season where NBC Sunday Night Football telecasts preempt the 6 p.m. newscast and a special hour-long newcast on Thursday nights also during the NFL season where Thursday Night Football telecasts shorten the 4 p.m. newscast to 30 minutes and preempt the 5 p.m. and 6 p.m. newscasts. On election nights, KNBC runs a special extended edition of its 11 p.m. newscast to show early election results.

NBC4’s Investigative Team (I-Team) features former KCBS reporter Joel Grover as its lead investigator. In 2013, NBC4 Southern California won the Investigative Reporters & Editors award for "In Harm’s Way", a series of reports on transportation safety, which resulted in changes to the rise in tour bus accidents and government policing of the industry including exposing one company and regulators shutting down six others.

KNBC has had a very stable news team over the years: weeknight anchor Colleen Williams (who also occasionally reports for MSNBC and NBC News), sports anchor Fred Roggin (also has the nickname "The Dean of L.A. Sports" and serves as sports announcer for NBC's Olympics coverage), and chief weathercaster Fritz Coleman (who like Roggin, has also occasionally appeared on The Tonight Show, and once hosted a late night variety show for KNBC called It's Fritz from 1989 to the early 1990s) have each been at the station at least thirty years or more. Former KNBC anchor Paul Moyer worked two stints at channel 4; first from 1972 to 1979 (when he began a 13-year run at rival KABC-TV) and from July 1992 until his April 2009 retirement. Like Moyer, anchor Chuck Henry was also a mainstay at KABC-TV, before making the move to channel 4 in January 1994. Kelly Lange, Stu Nahan, John Schubeck, Tritia Toyota, Jess Marlow, David Sheehan, John Beard and Nick Clooney are other notables who have worked on KNBC's newscasts in the past.

For most of the last 30 years, KNBC has waged a spirited battle with KABC-TV for the top-rated local newscast in Southern California, becoming a three-way race with KCBS-TV's ratings resurgence in 2006. Throughout the late 1980s and into the early 2000s, KNBC's newscasts were the most-watched in the region, beating out every other station viewership-wise, which coincided with NBC's overall ratings at the time. Channel 4's 11 p.m. newscast currently sits in first place (adults 25–54) and has been for nine months straight; most of the station's other newscasts, including its once-popular morning news program, Today in L.A., the area's first local morning newscast (which debuted in 1986), now is battling for second place.

Former Today co-host and NBC Nightly News anchor Tom Brokaw began his NBC career as an anchor and reporter for KNBC from 1966 until leaving to work exclusively for the network in 1973. Others of note who have worked at KNBC early in their careers (prior to joining the network) include Bryant Gumbel, Pat Sajak, Kent Shocknek, Bob Abernethy, Keith Morrison, Tom Snyder and consumer reporter David Horowitz, whose long-running syndicated series, Fight Back!, began on channel 4 and was produced and distributed by NBC and Group W. In 1987 during an afternoon newscast, a gun-wielding mental patient gained access to NBC Studios, and took Horowitz hostage live on-air. With the gun pressed to his side, Horowitz calmly read the gunman's statements on camera. The unidentified man was caught with a toy gun, and was arrested by local police. It led Horowitz to start a successful campaign to ban "look-alike" toy guns in several states, including California and New York.

Channel 4's news programs were known as KNBC News Service during the late 1960s and early 1970s, before adopting the NewsCenter 4 title in the mid-1970s. NBC made similar changes to newscasts in other markets around the same time, and channel 4 shared the NewsCenter title with its sister stations in New York, Washington, D.C. and Chicago. KNBC's newscasts were the last to drop the NewsCenter moniker, rebranding to News 4 LA in 1982 before becoming Channel 4 News in 1985. While KNBC became known on-air as NBC 4 in 1995, the Channel 4 News branding was so well established in Southern California that the title was retained for 26 years until 2011, when it became NBC 4 News.

In 2006, KNBC launched a local news channel on digital channel 4.4 called News Raw, that provided hourly news updates, additional information on breaking news stories and previewed news stories scheduled to air on the main channel's newscasts. After Universal Sports was launched in 2008, News Raw became a part-time channel, and was later dropped when KNBC expanded Universal Sports programming on the former subchannel to 24 hours a day. Mekahlo Medina, the host of News Raw, has received national attention for his integration of social media into local newscasts.

For many years, KNBC produced a late afternoon newscast at 4 p.m., which was dropped in 2002, in favor of Dr. Phil (that program moved to KCBS-TV in 2005, and was replaced by The Ellen DeGeneres Show). The station also had an hour-long 11 a.m. newscast, which later was trimmed to a half-hour before ultimately being canceled at the start of the 2010 Winter Olympics. The station revived its midday newscast as a half-hour program at noon in early 2012, which expanded to one hour that September. KNBC became the fifth station in the Los Angeles market to begin broadcasting its local newscasts in high definition on July 14, 2008 (Spanish-language sister station KVEA and former sister KWHY-TV also converted their newscasts to HD at the same time). On December 6, 2011, KNBC entered into a partnership with public radio station KPCC as part of a larger effort by NBCUniversal to partner with non-profit news organizations following its acquisition by Comcast.

In summer 2016, changes were brought to KNBC's daytime lineup. on May 30, the station moved the daytime talkshows Access Hollywood Live to noon as well as Steve Harvey and The Ellen DeGeneres Show to 2 p.m. and 3 p.m. respectively, while its midday newscast was moved to 11 a.m., following the cancellation of The Meredith Vieira Show; at that time KNBC would resume airing a 4 p.m. newscast, becoming the third Los Angeles television station to expand into the timeslot – possibly to complete with KCBS-TV and its sister independent station KCAL-TV (which moved its newscast from sister station KCBS-TV in 2002) and KABC-TV (which began airing its 4 p.m. newscast into the period in September 1980). On July 24, 2016, KNBC became the tenth (and final) NBC-owned station and the third (and final) owned station in the West Coast to use its "Look N" graphics that is first implemented by the NBC O&Os in the East Coast in summer of that year; also its mic flags were updated, the color scheme was now blue with a white 4 instead of its white with a blue 4 color scheme; prior to this, KNBC along with sister stations KNTV and KNSD revamped their websites on July 1, 2016. In July 2016, KNBC entered into a partnership agreement with Cumulus Media—owned radio station KABC-AM to carry the simulcasts of the first half-hour of Today in L.A. morning newscasts and the station's 6:00 p.m. weeknight newscasts; additionally, some of the station's on air talent were occasionally appeared as guests on KABC-AM's programs.
