A lattice tower or truss tower is a freestanding vertical framework tower . This construction is widely used in transmission towers carrying high-voltage electric power lines , in radio masts and towers (a self-radiating tower or as a support for aerials ) and in observation towers . Its advantage is good shear strength at a much lower weight than a tower of solid construction would have as well as lower wind resistance.

118-531: Sutro Tower is a unique three-legged 297.8 m (977 ft) tall TV and radio lattice tower located in San Francisco, California. Rising from a hill between Twin Peaks and Mount Sutro near Clarendon Heights , it is a prominent feature of the city skyline and a landmark for city residents and visitors. The tower was the tallest structure in San Francisco from the time of its completion in 1973 until it

236-525: A defamation lawsuit against KTVU, claiming the incident damaged the airline's reputation, but withdrew it a few days later, stating that it would instead "concentrate all [their] efforts on dealing with the aftermath of the accident." KTVU filed requests through the Digital Millennium Copyright Act to remove user-uploaded videos of the prank. The station contended that the takedowns were intended to lessen insensitivity towards

354-484: A Cause . KTVU exercised discretion and limited the number of commercial break interruptions during the movie telecasts, often airing the films uncensored and with commentary, either by a studio host or via slides. The station even televised the Metro-Goldwyn-Mayer film Hollywood Revue of 1929 with some of the original two-strip Technicolor sequences. During the early 1970s, the station began employing

472-466: A Fox station. For August 2010, KTVU's newscasts ranked No. 1 among adult viewers 25–54, beating KPIX, KGO, KNTV, and KRON. KTVU had used the "KTVU News Theme" by Michael Randall as the primary theme music for its newscasts from 1987 (debuting alongside a custom title sequence for the 10 p.m. newscast that was updated in 1994 and used until 2001, featuring a CGI fly-over of the Bay Area showcasing

590-459: A clear day, the tower can be seen from the East Bay peak of Mount Diablo and is sometimes the only part of San Francisco seen above the coastal fog when it is blown inland, typically on summer mornings and evenings. TV stations that transmit from Sutro Tower include the following. Most of these stations carry additional subchannels on their frequencies. Subchannel affiliations are shown via

708-402: A consortium with KTVU , KRON , and KPIX , the three other major San Francisco television broadcasters at the time, to build and maintain the tower. It stands 297.8 m (977 ft) above ground and 552 m (1,811 ft) above sea level. It is the second tallest structure in the city by ground-to-tip height, though its mountain location overlooks the city's downtown skyscrapers. Before

826-605: A demolished pier. Channel 2 was the fourth commercial television station to sign on in the Bay Area, and the first independent station in the market . It was the second television outlet in Northern California to have been assigned the KTVU call letters, which were previously used by a short-lived station on UHF channel 36 in Stockton , which operated from December 1953 to April 30, 1955. During its first 15 years on

944-606: A different programming strategy to stand out from the other independents in the market, acquiring first-run syndicated sitcoms and drama series, several comedies and dramas from the United Kingdom (such as Upstairs, Downstairs and The Benny Hill Show , the latter of which had some episodes re-edited by the station to remove scenes of frontal nudity accidentally left in the broadcast prints), and various nature series (including National Geographic specials) as alternative offerings. As an independent competitor, KTVU aired

1062-549: A fully spelled titling in 2001, before switching to partially numerical-based titling—as the Fox 2 10:00 News , mirroring similar titling schemes for newscasts used by some of its sister stations such as Los Angeles O&O KTTV —for six months starting in February 2015 under Fox ownership, before reverting to the previous title form), which for years had been the market's only local television newscast at 10 pm. Initially airing for

1180-459: A half-hour on Monday through Friday nights, the program was originally anchored by Les Nichols (who served as KTVU's managing editor ) and Al Helmso (who also served as the station's first news director ). The program has long established itself with top-drawer talent, many of whom have worked at KTVU for more than ten years. Though, early on, the program experienced turnover with its main anchor team. Nichols and Helmso stepped down as main anchors in

1298-495: A high of 10,000 tons as is the case in the Eiffel Tower to as low as a few hundred tons. They are built to a higher standard to support the weight of the oil platforms built on top of them and because of the forces to which they are subjected. As a result, the cost to build these structures can run into the hundreds of millions . These costs are justified due to the resulting oil and gas revenues, whereas land-based towers have

1416-506: A large portion of these towers is underwater, the official height of such structures is often held in dispute. The steel lattice truss for these structures, known as jackets in the oil industry, are typically far more robust and reinforced than their land-based counterparts, sometimes weighing more than 50,000 tons as is the case for the Bullwinkle and Baldpate platforms, whereas tall (above 1,000 feet) land-based lattice towers range from

1534-784: A larger presence in the markets of NFL teams that are part of the National Football Conference (such as the San Francisco 49ers and Seattle Seahawks ), the conference to which Fox holds broadcast rights . Fox had for many years wanted to have an owned-and-operated station in the San Francisco Bay Area, which has always been one of the ten largest Nielsen television markets. After Fox Television Stations assumed ownership of charter affiliate WTXF-TV in Philadelphia in 1995, KTVU became

1652-461: A much lower stream of revenue and therefore the capital costs of towers are typically much less. Since end of the 19th century, tall lattice towers were built. Lattice towers have even held the absolute height record. They are among the tallest free-standing architectural structures and hold a number of national records, such as the tallest free-standing or even overall tallest structure of a country. List of all supertall lattice tower structures in

1770-506: A new graphics package, accompanied by the replacement of the "Icon News" package with OSI Music's "Fox Affiliate News Theme", matching with the imaging style of other Fox Television Stations-owned outlets and implementing the "Fox 2" brand universally. On June 22, 2015 (originally announced in an April 14 release that also announced the expansion of Mornings on 2 by a half-hour earlier at 4 a.m. on April 20), KTVU debuted an hour-long 4 p.m. newscast. On September 4, 2023, KTVU expanded

1888-430: A news summary during the first half-hour. The program was reformatted into a more traditional newscast in 1990, as The Noon News , at which time it was shortened to a half-hour (the newscast would eventually revert to an hour on April 7, 2016 ). In September 1989, the station debuted a half-hour 6 p.m. newscast, The 6:00 News , which lasted until its cancellation in 1991. Channel 2 eventually decided to shift towards

2006-535: A news-intensive format to compete with KRON, KPIX, KGO-TV and KNTV that took the course of several years to take effect; Fox has never carried any national network newscasts (aside from news updates produced out of its New York City station WNYW that aired during prime time from 1987 to 1990, and four attempts at newsmagazines between 1987 and 2003), but it still motivated its affiliates, including KTVU, to air more local news programming. The station's original morning newscast, Mornings on 2 , debuted on January 2, 1991, as

2124-524: A newscast at 10 p.m. on May 16, 2016 ). Moreover, WB affiliate KBWB (now KOFY-TV) canceled its KNTV-produced 10 p.m. newscast after four years in 2002, as it was unable to compete with KTVU in the ratings. During this period, KTVU branded its flagship newscast as The Original Ten O'Clock News . The Ten O'Clock News is also one of the few local newscasts in the United States to have been syndicated to other television stations. As of 2016 ,

2242-442: A nightly film showcase, The 8 O'Clock Movie , as an alternative to network programs that aired during prime time on then-NBC affiliate KRON-TV, CBS station KPIX (channel 5) and ABC -owned KGO-TV (channel 7). Continuing into its early years as a Fox affiliate, KTVU frequently aired classic movies (around 20 per week) in the 8 p.m. time slot as well as on Sunday afternoons. Many of the films presented were prints restored by

2360-518: A no-nonsense journalistic style for The 10 o'clock News that was based around in-depth and fair reporting, largely devoid of the " happy talk " banter among anchors that was common of other local television newscasts. During Zehnder's tenure, KTVU became one of the most respected local television news operations in the United States and earned several journalism awards over the next two decades, including Emmy, Associated Press , Peabody and duPont-Columbia Awards . The 10 p.m. newscast's dominance

It was wherein the program that he introduced the Bay Area—and by extension, through KTVU's superstation status, the rest of the country—to Japanese anime by broadcasting such shows as Star Blazers and Ultra Man . Captain Cosmic was a hit, though it ended when Wilkins retired from television in 1979; former San Francisco Chronicle reporter and occasional co-host John Stanley took over as sole host of Creature Features from 1979 until its cancellation in 1982. Other local programs that aired on KTVU during its run as an independent station included

2832-494: A sister station to KPIX. With the advent of channel-sharing agreements after the 2016 FCC spectrum auction , San Jose 's KQEH began to transmit from Sutro with sister station KQED on January 17, 2018, moving from its former Monument Peak transmitter. Three other major Bay Area TV stations are unable to be located at Sutro Tower—the NBC -owned duopoly of KNTV and KSTS ; and KTVU's duopoly partner KICU-TV . KNTV, which assumed

2950-408: A sizeable amount of locally produced news, sports, talk and public affairs programming. In 1960, after acquiring camera, projection and slide equipment to transmit programming available in the format, the station began broadcasting its programming in color ; much of the programs that it broadcast in color consisted of movies and certain series acquired from the syndication market that were produced in

3304-589: A superstation for the remainder of its run as an independent, its cable coverage would become limited to providers within the Western United States—primarily those located in Northern California, Nevada , Oregon and select areas of Utah . The station continued to be distributed nationally, however, on direct broadcast satellite via C-Band systems until the late 1990s; KTVU was also carried on PrimeStar as its Fox network feed for

3422-473: A two-hour broadcast from 7 to 9 am, replacing animated series in the time period (the program would expand to three hours on September 14, 2015 ); as such, it became the fourth Fox station to air a newscast on weekday mornings. This was followed on August 5, 1996, by the debut of an additional hour-long newscast at 6 a.m. (which would gradually expand to three hours, now beginning at 4 am). Early evening newscasts later returned on March 27, 2000, with

3540-487: Is Cincinnati , Ohio, which features four towers above 900 feet in height. Tokyo is the only other city in the world that has more than one above that height. The majority of the tallest steel lattice towers in the world are actually built in water and used as oil platforms. These structures are usually built in large pieces on land, most commonly in Texas or Louisiana, and then moved by barge to their final resting place. Since

In October 1985, News Corporation —which had purchased a 50% interest in 20th Century Fox corporate parent TCF Holdings for $ 250 million in March 1985, and also acquired John Kluge 's Metromedia family of independent television stations in May 1985—announced its intentions to create a fourth television network that would use

4130-400: The attack on Paul Pelosi , KTVU inaccurately reported that the attacker was in his underwear at the time of the incident. The station subsequently retracted this claim and removed mention of the underwear from the relevant article; however, social media users and conservative public figures including Dinesh D'Souza began repeating the underwear claim as if it were fact. The station's signal

4248-743: The "early prime" network scheduling experiment in February 1992, The Ten O'Clock News handily beat the late evening newscasts that both stations had consequently moved up to 10 pm. KRON would move its late news back to the 11 p.m. slot in September 1993; KPIX would not follow suit until September 1998 (although it would later begin producing a competing half-hour 10 p.m. newscast for KBCW in March 2008). In stark contrast, when KRON became an independent station in January 2002, it initially scheduled its new prime time newscast at 9 p.m. to avoid competing directly with KTVU (KRON would eventually restore

4366-464: The 1980s. One of the station's most successful programs—both in terms of ratings and cultural impact—was Creature Features , a Saturday prime time showcase of horror movies that was originally hosted by Bob Wilkins , who had earlier hosted a popular and similarly themed show at KCRA-TV in Sacramento . Wilkins brought a straight presentation and dry wit to a television genre made ridiculous by

4484-623: The 1984 science fiction film Dune , which combined footage from the Alan Smithee television cut with the original theatrical release (thereby restoring all the violence featured in the latter cut, while eliminating some of the objectionable edits that caused director David Lynch to remove his name from the credits of the television print). KTVU also carried programming from the Operation Prime Time programming service (at least) in 1978. Channel 2 adapted to competition over

4602-602: The 1990s. Its newscasts became the highest-rated among the Bay Area's television stations in the early 2000s, firmly taking first place from KRON-TV following Channel 4's January 2002 disaffiliation from NBC.

The station received complaints after the 6 p.m. newscast on October 9, 2019, featured a headline about the Atlanta Braves being "scalped" when losing the deciding Game 5 of the National League Division Series to the St. Louis Cardinals , 13–1. Viewers who took to social media to express their disapproval stated the station used language considered to be insensitive to

4838-637: The CBS affiliate in Seattle, which would have displaced that market's charter Fox affiliate, KCPQ ; such a purchase never materialized, although Fox did attempt to buy KCPQ outright before renewing its affiliation contract with that station in July 2014, after it was unsuccessful in pressuring Tribune Broadcasting to sell KCPQ by purchasing and proposing to move its programming to Bellingham, Washington -based KBCB ; Fox would eventually acquire KCPQ in 2020 after Tribune

4956-505: The Fox wordmark logo was added onto the underside of the top line of "Circle Laser 2"; the station also concurrently changed its branding to "KTVU Fox 2" as the network tightened its branding standardizations for its stations—although the previous "KTVU Channel 2" moniker remained in use as part of its newscast branding (the "Fox 2" logo was also used on its newscasts in April 1997, but the moniker

5074-542: The Giants extended to the franchise's ownership, as Cox Enterprises owned a 10% stake in the Giants during the latter years of the broadcast contract ).

6136-764: The San Francisco–Oakland–San Jose market. Channel 2's affiliation with Fox could be seen as a major coup for the fledgling network, because of its distinction as the highest-rated independent station in the Bay Area as well as one of the strongest independents in the U.S. It was also one of the few independents to affiliate with the network which broadcast on the VHF band and had an established local news identity. KTVU and Cox's other two independent stations, WKBD-TV in Detroit and KDNL-TV in St. Louis , officially joined Fox seven months later on October 9, 1986, when

The Saturday and Sunday editions of KTVU's 6 p.m. newscast is subject to preemption or delay due to network sports telecasts overrunning into or starting within either time slot; since April 2016, sister station KICU has served as an alternate broadcaster of KTVU newscasts that are preempted by network sports telecasts. KTVU

6490-510: The addition of a half-hour at 4:30 am. In March 2014, KTVU began using the AFD No. 10 broadcast flag to present its newscasts in letterboxed widescreen for viewers watching on cable through 4:3 television sets (the AFD No. 10 flag had already been used to show Fox programming on the station in the letterbox format on Bay Area cable and IPTV providers).

6962-468: The construction of Sutro Tower in 1973, television reception in San Francisco was spotty because the many hills of the city blocked the line-of-sight television signal. The great height of the new tower helped to resolve that problem. Transmitters had been scattered throughout the Bay Area, including at San Bruno Mountain , Mt. Allison , Monument Peak , and Mt. Diablo . By having all the main Bay Area television station transmitters in one location, reception

7080-605: The debut of a new half-hour 6 p.m. newscast (which expanded to an hour on April 25, 2016), followed in April 2005 by the addition of an hour-long 5 p.m. newscast on weekdays (an expansion of an existing weekend-only newscast that debuted in 1998). Besides beating out its competition in the 10 p.m. time slot, The Ten O'Clock News has also placed ahead of KRON, KPIX and KGO's 11 p.m. newscasts in overall late news viewership for much of its history; however as its news programming expanded, KTVU's newscasts avidly competed for first overall with KRON-TV and KGO-TV during

7198-567: The demise of the International Roller Derby League in 1973. During the early 2000s, KTVU broadcast San Francisco's Chinese New Year Parade each winter; sister station KICU generally rebroadcast the parade on the evening of its broadcast (independent station KTSF , channel 26, aired its own Chinese-language telecast of the parade using "pool" cameras).
