93-559: Dateline NBC (also known simply as Dateline ) is a weekly American television news magazine reality legal show that is broadcast on NBC . It was previously the network's flagship general interest news magazine, but now focuses mainly on true crime stories with only occasional editions that focus on other topics. The program airs Fridays at 10:00 p.m. Eastern Time (9:00 p.m. Eastern for special two-hour editions). Special weekend encore editions also air at 9 or 10:00 p.m. (two-hour editions at 7 and 8:00 p.m. depending on

186-560: A press pass before the outing happened. A DEF CON source at NBC News had tipped off organizers to Madigan's plans. To Catch a Predator was a special series of reports, hosted by Chris Hansen , featuring hidden camera sting operations that bust potential sex offenders who carry out online chats with children with the intent of luring them to meet in person and engage in illegal sexual activity. The stings are conducted in partnership with Perverted-Justice , and begin for each potential offender with recordings of online chats of him with

279-425: A " decoy " employed with the organization, posing as minor, generally between the ages of 12 and 15. If the potential offender and the decoy make an appointment, this is at the pretended home of the pretended minor, which is in fact a house prepared for the television show, with police hiding outside for the subsequent arrest of the offender outside the house. During the filming of each episode, men who attempt to meet

372-474: A 5:3 (1.67:1) aspect ratio and 60 Hz refresh rate. The Society of Motion Picture and Television Engineers (SMPTE), headed by Charles Ginsburg, became the testing and study authority for HDTV technology in the international theater. SMPTE would test HDTV systems from different companies from every conceivable perspective, but the problem of combining the different formats plagued the technology for many years. There were four major HDTV systems tested by SMPTE in

465-506: A Con Man was a series of hidden camera investigations devoted to the subject of identifying and detaining con men who attempted to extract money from victims in advance fee fraud scams, although some editions also focused on exposing and catching identity thieves . The stories, which were also reported by Chris Hansen (who called the identity thieves that the series investigates "a different kind of predator"), were conducted as an undercover sting operation in partnership with cardcops.com,

558-625: A clearer, more detailed picture. In addition, progressive scan and higher frame rates result in a picture with less flicker and better rendering of fast motion. Modern HDTV began broadcasting in 1989 in Japan, under the MUSE /Hi-Vision analog system. HDTV was widely adopted worldwide in the late 2000s. All modern high-definition broadcasts utilize digital television standards. The major digital television broadcast standards used for terrestrial, cable, satellite, and mobile devices are: These standards use

651-420: A comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved. Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format. An aspect ratio of 16:9 was duly agreed upon at

744-533: A credit card watchdog group which investigates identity thefts and aims to catch the suspects in the act. Richard Engel hosted a tie-in version leading into The Blacklist about significant crimes and conspiracies. The Widower is Dateline's first ever docuseries. The Widower takes viewers behind the scenes of a decade-long investigation into Thomas Randolph, an eccentric Las Vegas man accused of killing his wife Sharon. With hundreds of hours of exclusive footage, Dateline NBC veteran producer Dan Slepian captures

837-613: A daily newscast, news magazines allow more in-depth coverage of specific topics, including current affairs , investigative journalism (including hidden camera investigations), major interviews, and human-interest stories. The BBC 's Panorama was one of the earliest examples, premiering in 1953. In the United States , the Big Three networks all currently produce at least one weekly news magazine, including ABC 's 20/20 , CBS 's 60 Minutes , and NBC's Dateline ;

930-743: A digital format from DVB. The first regular broadcasts began on January 1, 2004, when the Belgian company Euro1080 launched the HD1 channel with the traditional Vienna New Year's Concert . Test transmissions had been active since the IBC exhibition in September 2003, but the New Year's Day broadcast marked the official launch of the HD1 channel, and the official start of direct-to-home HDTV in Europe. Euro1080,

1023-404: A division of the later defunct Belgian TV services company Alfacam, broadcast HDTV channels to break the pan-European stalemate of "no HD broadcasts mean no HD TVs bought means no HD broadcasts ..." and kick-start HDTV interest in Europe. The HD1 channel was initially free-to-air and mainly comprised sporting, dramatic, musical and other cultural events broadcast with a multi-lingual soundtrack on

1116-463: A fraud prevention expert. The Friday night edition of Dateline features special emphasis on true crime stories, which previously included the "To Catch a Predator" series. Most NBC News specials, either in the form of special interviews or extended special reports on pertinent breaking news stories that occurred earlier in the day, are also broadcast under the Dateline banner. However, on occasion,

1209-496: A full-time streaming channel made up of Dateline episodes since its July 2020 launch. NBC News' free streaming channel NBC News NOW also airs episodes of Dateline NBC every weekend. On September 25, 2017, Dateline began airing archived true crime-focused episodes in daily broadcast syndication ; the NBC branding is completely removed. These episodes also air as part of MyNetworkTV 's Wednesday and Thursday night lineups. Dateline

1302-559: A global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 led to the acceptance of recommendations ITU-R BT.709 . In anticipation of these standards, the DVB organization was formed. It was alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI . DVB created first

1395-428: A larger focus on tabloid stories (including celebrities such as Michael Jackson , and the O.J. Simpson and Menendez brothers murder cases) rather than the harder journalism associated with 60 Minutes and 20/20 at the time. CNN president Ed Turner argued that these shows had eclipsed the networks' evening newscasts as their flagship programs at the expense of their news divisions' traditions of hard news. By

1488-428: A larger push into the medium by the division, NBC News launched a Dateline podcast; the podcast launched with the seven-episode story 13 Alibis . Dateline producers stated that the podcast stories would be able to go more in-depth on topics than the television series, and did not rule out other types of content—including audio-only versions of stories from its archives, as well as extensions and updates to stories from

1581-400: A much wider set of frame rates: 59.94i, 60i, 23.976p, 24p, 29.97p, 30p, 59.94p and 60p. In the days of standard-definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. Sixty Hertz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation

1674-686: A rarity as Canadian networks do not generally simulcast American newsmagazines. Dateline NBC is also seen on the 24-hour news network Orbit News in Europe and the Middle East , which broadcasts MSNBC and other NBC News programs for several hours a day. It is also broadcast on the Seven Network in Australia on Sundays at 5 a.m., although is pre-empted by paid programming on regional affiliates Prime Television and Golden West Network . In

1767-434: A rolling schedule of four or five hours per day. These first European HDTV broadcasts used the 1080i format with MPEG-2 compression on a DVB-S signal from SES 's Astra 1H satellite. Euro1080 transmissions later changed to MPEG-4/AVC compression on a DVB-S2 signal in line with subsequent broadcast channels in Europe. Despite delays in some countries, the number of European HD channels and viewers has risen steadily since

1860-400: A sample of a low-speed accident in which the fuel tank exploded; the explosion during the crash test would later be discovered to have been staged by an expert witness for hire against GM, Bruce Enz of The Institute for Safety Analysis. Enz used incendiary devices and a poorly fitted gas cap to create the impression of a dangerous vehicle. The program did not disclose the fact that the accident

1953-605: A similar strategy of "stripping" with The Jay Leno Show in 2009). In its prime, from 1995 to 1999, Dateline provided significant breaking news coverage. The program featured sensationalized news stories and drew in viewers with stories aired in multiple installments. By 1999, any one individual Dateline edition placed in Nielsen 's top 10 most-watched television programs among total viewers during most weeks. NBC capitalized on its relationship with CNBC and MSNBC by airing repackaged stories seen on past Dateline broadcasts on

2046-503: A single story format, although in the past the program maintained a traditional newsmagazine format with multiple segments of varying length, such as with the Sunday version, which in particular still occasionally features multiple story packages that are tied to a specific theme. Unlike the other flagship newsmagazines on U.S. television ( CBS ' 60 Minutes and ABC 's 20/20 ), Dateline featured more character-driven stories focusing on

2139-466: A story using hidden cameras to focus on an issue of public concern; and Newsmakers , light interviews with major figures in politics, entertainment, and business, as well as regular people in the news. The program also included cross-promotional segments with Court TV and magazines People , Good Housekeeping and Consumer Reports . In the 1990s, a common week would feature several "signature segments," breaking news, updates on past stories shown on

2232-588: A substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the standard video format used in most broadcasts: terrestrial broadcast television , cable television , satellite television . HDTV may be transmitted in various formats: When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television). The increased resolution provides for

2325-551: A top broadcasting administrator in Japan admitted failure of its analog-based HDTV system, saying the U.S. digital format would be more likely a worldwide standard. However this announcement drew angry protests from broadcasters and electronic companies who invested heavily into the analog system. As a result, he took back his statement the next day saying that the government will continue to promote Hi-Vision/MUSE. That year NHK started development of digital television in an attempt to catch back up to America and Europe. This resulted in

2418-511: A variety of video codecs , some of which are also used for internet video . The term high definition once described a series of television systems first announced in 1933 and launched starting in August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true HDTV spanned

2511-633: Is broadcast in Canada, mainly through NBC and MyNetworkTV affiliates from U.S. border cities (such as KING-TV and KZJO in Seattle , WDIV-TV and WADL in Detroit , and WGRZ-TV and WNYO-TV in Buffalo, New York ) that are widely available in that country; until the fall of 2022, new editions of the show were not simulcast on a Canadian network nationwide, though many of the same Canadian counterparts to

2697-491: Is no single standard for HDTV color support. Colors are typically broadcast using a (10-bits per channel) YUV color space but, depending on the underlying image generating technologies of the receiver, are then subsequently converted to a RGB color space using standardized algorithms. When transmitted directly through the Internet, the colors are typically pre-converted to 8-bit RGB channels for additional storage savings with

2790-495: Is not the first HDTV service over digital terrestrial television in Europe; Italy's RAI started broadcasting in 1080i on April 24, 2008, using the DVB-T transmission standard. In October 2008, France deployed five high definition channels using DVB-T transmission standard on digital terrestrial distribution. HDTV broadcast systems are identified with three major parameters: If all three parameters are used, they are specified in

2883-437: Is required to avoid ambiguity. Nevertheless, 29.97p/59.94i is almost universally called 60i, likewise 23.976p is called 24p. For the commercial naming of a product, the frame rate is often dropped and is implied from context (e.g., a 1080i television set ). A frame rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second. There

2976-514: Is the use of highly efficient modulation techniques for further reducing bandwidth, and foremost for reducing receiver-hardware and antenna requirements. In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate,

3069-468: Is used in all digital HDTV storage and transmission systems will distort the received picture when compared to the uncompressed source. ATSC and DVB define the following frame rates for use with the various broadcast standards: The optimum format for a broadcast depends upon the type of videographic recording medium used and the image's characteristics. For best fidelity to the source, the transmitted field ratio, lines, and frame rate should match those of

3162-519: The Federal Communications Commission (FCC) because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC. The limited standardization of analog HDTV in the 1990s did not lead to global HDTV adoption as technical and economic constraints at

3255-544: The ISDB format. Japan started digital satellite and HDTV broadcasting in December 2000. High-definition digital television was not possible with uncompressed video , which requires a bandwidth exceeding 1   Gbit/s for studio-quality HD digital video . Digital HDTV was made possible by the development of discrete cosine transform (DCT) video compression . DCT coding is a lossy image compression technique that

3348-462: The 240-line with its 25 Hz frame rate. The 240-line system could have doubled its frame rate but this would have meant that the transmitted signal would have doubled in bandwidth, an unacceptable option as the video baseband bandwidth was required to be not more than 3 MHz. Color broadcasts started at similar line counts, first with the US NTSC color system in 1953, which was compatible with

3441-452: The CMTT and ETSI, along with research by Italian broadcaster RAI , developed a DCT video codec that broadcast near-studio-quality HDTV transmission at about 70–140 Mbit/s. The first HDTV transmissions in Europe, albeit not direct-to-home, began in 1990, when RAI broadcast the 1990 FIFA World Cup using several experimental HDTV technologies, including the digital DCT-based EU 256 codec,

3534-526: The Japanese public broadcaster NHK first developed consumer high-definition television with a 5:3 display aspect ratio. The system, known as Hi-Vision or MUSE after its multiple sub-Nyquist sampling encoding (MUSE) for encoding the signal, required about twice the bandwidth of the existing NTSC system but provided about four times the resolution (1035i/1125 lines). In 1981, the MUSE system was demonstrated for

3627-595: The Philippines, the program airs on TAP Edge . NOTE: Data from 2007 to present includes Live+ Ratings. News magazine Radio news magazines are similar to television news magazines. Unlike radio newscasts, which are typically about five minutes in length, radio news magazines can run from 30 minutes to three hours or more. Television news magazines provide a similar service to print news magazines, but their stories are presented as short television documentaries rather than written articles; in contrast to

3720-468: The Sunday broadcasts (airing in a time slot otherwise reserved for family-friendly programming, aside from CBS ' competitor 60 Minutes ) focuses on stories tailored for younger viewers, such as recent Sunday reports on teen drivers and child safety; on other weeks, the Sunday editions feature either true crime stories, stories recounting situations in which people have survived life-threatening situations, consumer reports or interviews. Dateline features

3813-496: The U.S. have produced news magazines, although they have largely been displaced by cheaper programming acquired from the syndication market. An exception is WCVB-TV in Boston, which has continued to produce the nightly news magazine Chronicle since 1982. In Brazil, TV Globo 's news magazine Fantástico has aired on Sunday nights. Historically, it has been one of the top programs on Brazilian television, although its dominance

3906-696: The United Kingdom became the first European country to deploy high-definition content using the new DVB-T2 transmission standard, as specified in the Digital TV Group (DTG) D-book , on digital terrestrial television. The Freeview HD service contains 13 HD channels (as of April 2016 ) and was rolled out region by region across the UK in accordance with the digital switchover process, finally being completed in October 2012. However, Freeview HD

3999-768: The United States occurred on July 23, 1996, when the Raleigh, North Carolina television station WRAL-HD began broadcasting from the existing tower of WRAL-TV southeast of Raleigh, winning a race to be first with the HD Model Station in Washington, D.C. , which began broadcasting July 31, 1996 with the callsign WHD-TV, based out of the facilities of NBC owned and operated station WRC-TV . The American Advanced Television Systems Committee (ATSC) HDTV system had its public launch on October 29, 1998, during

4092-465: The United States saw Hi-Vision/MUSE as an outdated system and had already made it clear that it would develop an all-digital system. Experts thought the commercial Hi-Vision system in 1992 was already eclipsed by digital technology developed in the U.S. since 1990. This was an American victory against the Japanese in terms of technological dominance. By mid-1993 prices of receivers were still as high as 1.5 million yen (US$ 15,000). On February 23, 1994,

4185-521: The assumption that it will only be viewed only on a ( sRGB ) computer screen. As an added benefit to the original broadcasters, the losses of the pre-conversion essentially make these files unsuitable for professional TV re-broadcasting. Most HDTV systems support resolutions and frame rates defined either in the ATSC table 3, or in EBU specification. The most common are noted below. At a minimum, HDTV has twice

4278-438: The audience's emotional attachment to the persons featured, and fewer non-character driven international and national news stories. However, the success of Dateline led to the other networks to create additional versions of their newsmagazines, 60 Minutes II and additional nights of 20/20 (which were often not as successful). Executive producer Neal Shapiro pioneered several "signature segments" that appeared regularly on

4371-427: The cable networks mentioned in the syndication section air the repackaged Dateline on... episodes as a part of their own schedules (especially those containing domestic stories), and some other American stations airing in Canada carry the Dateline syndicated package outside of network hours. Since the fall of 2022, Citytv simultaneously airs new episodes of Dateline with NBC in Canada (with domestic advertising),

4464-506: The charred wreckage of the GM pickups. It was also later revealed that the Dateline report had been dishonest about the fuel tanks rupturing and the alleged 30 miles per hour (48 km/h) speed at which the collision was conducted. The actual speed was found to be higher than stated, around 40 miles per hour (64 km/h), and after x-ray examination of the fuel tanks from the C/K pickups used in

4557-620: The confounding murder investigation that soon reveals Sharon was Randolph's sixth wife - and the fourth to die under mysterious circumstances. A spin-off series, Dateline: The Last Day premiered on June 14, 2022 on Peacock . Dateline focuses on true crime and human interest stories, predominantly featuring a single story for the entire program. Keith Morrison often serves as narrator for certain editions, usually reporting on real-life murder mysteries chronicled in many editions, and cliffhangers are used prior to commercial breaks. Famous con man Steve Comisar appeared regularly on Dateline as

4650-436: The current formats of 20/20 and Dateline focus predominantly on true crime stories. News magazines proliferated on network schedules in the early 1990s, as they had lower production costs in comparison to scripted programs, and could attract equivalent if not larger audiences. At the same time, newer newsmagazines—as well as syndicated offerings such as A Current Affair , Hard Copy and Inside Edition —often had

4743-712: The earlier monochrome systems and therefore had the same 525 lines per frame. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625-line broadcasts. The NHK (Japan Broadcasting Corporation) began researching to "unlock the fundamental mechanism of video and sound interactions with the five human senses" in 1964, after the Tokyo Olympics. NHK set out to create an HDTV system that scored much higher in subjective tests than NTSC's previously dubbed HDTV . This new system, NHK Color, created in 1972, included 1125 lines,

4836-457: The entire 20th century, as each new system became higher definition than the last. In the early 21st century, this race has continued with 4K , 5K and 8K systems. The British high-definition TV service started trials in August 1936 and a regular service on 2 November 1936 using both the (mechanical) Baird 240 line sequential scan (later referred to as progressive ) and the (electronic) Marconi-EMI 405 line interlaced systems. The Baird system

4929-456: The first HDTV broadcasts, with SES's annual Satellite Monitor market survey for 2010 reporting more than 200 commercial channels broadcasting in HD from Astra satellites, 185 million HD capable TVs sold in Europe (£60 million in 2010 alone), and 20 million households (27% of all European digital satellite TV homes) watching HD satellite broadcasts (16 million via Astra satellites). In December 2009,

5022-546: The first daily high-definition programs in the world, with regular testing starting on November 25, 1991, or "Hi-Vision Day" – dated exactly to refer to its 1,125-lines resolution. Regular broadcasting of BS -9ch commenced on November 25, 1994, which featured commercial and NHK programming. Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by

5115-647: The first meeting of the IWP11/6 working party at the BBC's Research and Development establishment in Kingswood Warren. The resulting ITU-R Recommendation ITU-R BT.709-2 (" Rec. 709 ") includes the 16:9 aspect ratio, a specified colorimetry , and the scan modes 1080i (1,080 actively interlaced lines of resolution) and 1080p (1,080 progressively scanned lines). The British Freeview HD trials used MBAFF , which contains both progressive and interlaced content in

5208-486: The first time and became permanent host shortly thereafter. Dateline began broadcasting in high definition for the first time on July 21, 2008, with an episode titled "Tower Dogs". Dateline previously shared the multi-level Studio 1A with Today . However, in 2013, the program moved back to Studio 3K, where the early-morning news programs Early Today and MSNBC 's Morning Joe First Look are also broadcast. Lester Holt replaced Ann Curry as host of Dateline with

5301-471: The first time in the United States, using the same 5:3 aspect ratio as the Japanese system. Upon visiting a demonstration of MUSE in Washington, US President Ronald Reagan was impressed and officially declared it "a matter of national interest" to introduce HDTV to the US. NHK taped the 1984 Summer Olympics with a Hi-Vision camera, weighing 40 kg. Satellite test broadcasts started June 4, 1989,

5394-1084: The following form: [frame size][scanning system][frame or field rate] or [frame size]/[frame or field rate][scanning system] . Often, frame size or frame rate can be dropped if its value is implied from context. In this case, the remaining numeric parameter is specified first, followed by the scanning system. For example, 1920×1080p25 identifies progressive scanning format with 25 frames per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i25 or 1080i50 notation identifies interlaced scanning format with 25 frames (50 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i30 or 1080i60 notation identifies interlaced scanning format with 30 frames (60 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 720p60 notation identifies progressive scanning format with 60 frames per second, each frame being 720 pixels high; 1,280 pixels horizontally are implied. Systems using 50 Hz support three scanning rates: 50i, 25p and 50p, while 60 Hz systems support

5487-412: The home in question. The segment was cancelled in early 2008 in part due to criticism of the show as well as legal issues. “Wild Wild Web” was a limited Dateline series in which host Chris Hansen would go undercover to reply to illegal or unethical online advertisements. With hidden cameras rolling, Hansen and his producers met with a hitman, people selling body parts, and sweetheart swindles. To Catch

5580-411: The intended definition. All of these systems used interlacing and a 4:3 aspect ratio except the 240-line system which was progressive (actually described at the time by the technically correct term sequential ) and the 405-line system which started as 5:4 and later changed to 4:3. The 405-line system adopted the (at that time) revolutionary idea of interlaced scanning to overcome the flicker problem of

5766-421: The late-1990s, Dateline would establish a niche in true crime to set it apart from its competitors—a format that would bolster its popularity, and lead the show to being on as many as five times per-week at its peak. Most of these magazines and their frequent airings would fall out of favor by the 2000s, being largely displaced by the emerging genre of reality television . Some local television stations in

5859-434: The light news-focused Real Life with Jane Pauley , poorly paired with a tabloid newsmagazine, Exposè . The program debuted on March 31, 1992, initially airing only on Tuesdays, with Jane Pauley and Stone Phillips serving as its co-anchors. Tom Brokaw and Katie Couric joined the program when the previously separate newsmagazine Now with Tom Brokaw and Katie Couric was converted into Dateline Wednesday . Gradually,

5952-491: The linear resolution of standard-definition television (SDTV), thus showing greater detail than either analog television or regular DVD . The technical standards for broadcasting HDTV also handle the 16:9 aspect ratio images without using letterboxing or anamorphic stretching, thus increasing the effective image resolution. A very high-resolution source may require more bandwidth than available in order to be transmitted without loss of fidelity. The lossy compression that

6045-553: The live coverage of astronaut John Glenn 's return mission to space on board the Space Shuttle Discovery . The signal was transmitted coast-to-coast, and was seen by the public in science centers, and other public theaters specially equipped to receive and display the broadcast. Between 1988 and 1991, several European organizations were working on discrete cosine transform (DCT) based digital video coding standards for both SDTV and HDTV. The EU 256 project by

6138-469: The main Tuesday slot being eliminated in 2004. Dateline was the first "multi-night" franchise that "established brand power by ' stripping ' editions," a strategy by NBC's entertainment division to place the program in the same time slot every week. It was considered to be a singular program rather than multiple weekly programs, and included many teasers and multiple installment interviews (NBC later tried

6231-564: The minor in person are filmed as they enter inside the "sting" house. Shortly after the target is inside, often after talking to the Perverted-Justice decoy (who either briefly meets with the men or converses with them from another room), Hansen would confront each suspect and ask them about their online conversations (which were transcribed and printed) with the decoy. After the confrontation, the men are taken into custody by local police. Some men were arrested even if they never entered

6324-592: The mixed analog-digital HD-MAC technology, and the analog MUSE technology. The matches were shown in 8 cinemas in Italy, where the tournament was played, and 2 in Spain. The connection with Spain was made via the Olympus satellite link from Rome to Barcelona and then with a fiber optic connection from Barcelona to Madrid . After some HDTV transmissions in Europe, the standard was abandoned in 1993, to be replaced by

6417-479: The network names suffixing the generic branding of Dateline on... . Several other brandings exist, with Dateline: Secrets Uncovered as a part of Oxygen , Dateline: Real Life Mysteries on TLC (along with Dateline on TLC ), and Dateline Extra the branding for repackaged episodes on MSNBC , also owned by NBCUniversal. All episodes are repackaged by NBC News under its non-fiction Peacock Productions banner. The NBCUniversal streaming service Peacock has featured

6510-535: The network, compared to the fifteen newsmagazines (often cloning the formulas of 20/20 and 60 Minutes ) NBC tried from the mid-70s until its debut which each debuted and ended ignominiously, often in the same year, or even the month they premiered, and were barely promoted, much less needed, during NBC's ratings domination entertainment-wise in the 1980s. It also served to smooth relations with original anchor Jane Pauley , who had been controversially pushed out from Today and seen her own primetime make-up vehicle,

6603-430: The night). One or two-hour feature-length editions sometimes air on any given scheduled evening, often to fill vacancies in the primetime schedule on the program's respective nights due to program cancellations. In February 2021, the program aired its first ever docuseries, "The Widower", a five-hour true crime saga about a man who married six women, four of whom died. Dateline is historically notable for its longevity on

6696-411: The program expanded with the addition of a third night (on Friday) in 1994 and a fourth night (on Monday) in 1997, peaking at five nights a week with Sundays in mid-1999 and 2000. The number of nights that the program aired began to be reduced due to viewer exhaustion and the rise of equally economic and popular reality television programming. Editions first began to be removed in the spring of 2001, with

6789-406: The program, multi-part investigations, and interviews. Dateline also pioneered the use of viewer feedback including telephone polling and a unique format, the "Interactive Dateline Mystery," where viewers voted (similar to Choose Your Own Adventure ) on where the story should go next. In 2019, taking advantage of the recent popularity of true crime podcasts such as Serial , and as part of

6882-629: The program. These included Dateline: Survivor , in which a person recounts a near-death experience and their eventual rescue; Dateline Timeline , in which a popular product, person and music single are shown/played that viewers are invited to guess what year it was from; State of the Art , explaining how a special effect or stunt in a movie was technically accomplished; Consumer Alert , in which common consumer complaints or issues (such as food safety and products of suspect quality that may be dangerous) are investigated, Dateline Hidden Camera Investigation ,

6975-456: The resignation of the news division's president Gartner, three Dateline NBC producers were dismissed as a result of the incident and the findings of the resulting investigation: executive producer Jeff Diamond, senior producer David Rummel, and Robert Read, producer of the report on the pickups. Michele Gillen, the correspondent involved in the segment, was transferred to NBC's Miami owned-and-operated station WTVJ , where she became an anchor of

7068-552: The retrospective series Headliners and Legends and Time and Again . The program first originated from NBC Studio 3K, using the same set that was used at the time for NBC Nightly News . When Today moved to its current facility, NBC Studio 1A, in 1994, Dateline took over Studio 3B and received its own brand-new dedicated set. Past contributing anchors were Bryant Gumbel , who left NBC in 1997, Maria Shriver , who left NBC in 2004, and Katie Couric , who left NBC in 2006. On June 24, 2005, Ann Curry co-anchored "Dateline" for

7161-494: The same encoding. It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format, and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.) HDTV technology

7254-584: The standard for DVB-S digital satellite TV, DVB-C digital cable TV and DVB-T digital terrestrial TV. These broadcasting systems can be used for both SDTV and HDTV. In the US the Grand Alliance proposed ATSC as the new standard for SDTV and HDTV. Both ATSC and DVB were based on the MPEG-2 standard, although DVB systems may also be used to transmit video using the newer and more efficient H.264/MPEG-4 AVC compression standards. Common for all DVB standards

7347-463: The start of the 20th season on September 23, 2011, shortly after Curry became permanent co-host of Today . On November 17, 1992, Dateline NBC aired an hour-long investigative report titled "Waiting to Explode," which focused on allegations that General Motors ' Rounded-Line Chevrolet C/K -Series pickup trucks exploded upon impact when involved in collisions due to the poor design of the vehicle model's fuel tanks. Dateline ' s footage showed

7440-484: The station's evening newscasts. In August 2007, Dateline reporter Michelle Madigan attempted to secretly record hackers admitting to crimes at that year's DEF CON in Las Vegas, Nevada . After being outed by DEF CON founder Jeff Moss during an assembly, she was heckled and chased out of the conference by attendees for her use of covert audio and video recording equipment. DEF CON staff tried to get Madigan to obtain

7533-561: The subsequent settlement were arguably the most devastating blows for NBC in a series of reputation damaging incidents during the 1990s and early 2000s. Within NBC, Michael Gartner , who resigned under pressure shortly after the incident, was the source for much of the blame. NBC News President Reuven Frank stated Gartner was hired in 1988, despite having no background in television news, in an attempt to satisfy parent company General Electric , by replacing current journalists with cheaper, less experienced reporters and producers. In addition to

7626-587: The televised collision, it was found that they had not ruptured and were intact. GM subsequently filed an anti-defamation/ libel lawsuit against NBC after conducting an extensive investigation. On February 8, 1993, after announcing the lawsuit, GM conducted a highly publicized point-by-point rebuttal in the Product Exhibit Hall of the General Motors Building in Detroit that lasted nearly two hours. The General Motors lawsuit and

7719-584: The television series. In August 2022, when the podcast launched a premium subscription on Apple Podcasts , the Dateline podcast had 775 million downloads, and was ranked as the sixth-largest podcast in the U.S. by Podtrac. Anchor Contributing anchors Correspondents Former anchors Former correspondents Repackaged hour-long true crime episodes of Dateline air on various cable and satellite channels such as Investigation Discovery , E! , USA Network (E! and USA are owned by NBC parent company NBCUniversal ) and OWN , usually with

7812-543: The time did not permit HDTV to use bandwidths greater than normal television. Early HDTV commercial experiments, such as NHK's MUSE, required over four times the bandwidth of a standard-definition broadcast. Despite efforts made to reduce analog HDTV to about twice the bandwidth of SDTV, these television formats were still distributable only by satellite. In Europe too, the HD-MAC standard was considered not technically viable. In addition, recording and reproducing an HDTV signal

7905-424: The world already having split into two camps, 25/50 Hz and 30/60 Hz, largely due to the differences in mains frequency. The IWP11/6 working party considered many views and throughout the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors , which led to further developments in other areas. While

7998-545: Was a research project and the system was never deployed by either the military or consumer broadcasting. In 1986, the European Community proposed HD-MAC , an analog HDTV system with 1,152 lines. A public demonstration took place for the 1992 Summer Olympics in Barcelona. However HD-MAC was scrapped in 1993 and the DVB project was formed, which would foresee development of a digital HDTV standard. In 1979,

8091-684: Was a significant technical challenge in the early years of HDTV ( Sony HDVS ). Japan remained the only country with successful public broadcasting of analog HDTV, with seven broadcasters sharing a single channel. However, the Hi-Vision/MUSE system also faced commercial issues when it launched on November 25, 1991. Only 2,000 HDTV sets were sold by that day, rather than the enthusiastic 1.32 million estimation. Hi-Vision sets were very expensive, up to US$ 30,000 each, which contributed to its low consumer adaption. A Hi-Vision VCR from NEC released at Christmas time retailed for US$ 115,000. In addition,

8184-494: Was discontinued in February 1937. In 1938 France followed with its own 441-line system, variants of which were also used by a number of other countries. The US NTSC 525-line system joined in 1941. In 1949 France introduced an even higher-resolution standard at 819 lines , a system that would have been high definition even by modern standards, but was monochrome only and had technical limitations that prevented it from achieving

8277-582: Was first proposed by Nasir Ahmed in 1972, and was later adapted into a motion-compensated DCT algorithm for video coding standards such as the H.26x formats from 1988 onwards and the MPEG formats from 1993 onwards. Motion-compensated DCT compression significantly reduces the amount of bandwidth required for a digital TV signal. By 1991, it had achieved data compression ratios from 8:1 to 14:1 for near-studio-quality HDTV transmission, down to 70–140  Mbit/s . Between 1988 and 1991, DCT video compression

8370-615: Was introduced in the United States in the early 1990s and made official in 1993 by the Digital HDTV Grand Alliance , a group of television, electronic equipment, communications companies consisting of AT&T Bell Labs , General Instrument , Philips , Sarnoff , Thomson , Zenith and the Massachusetts Institute of Technology . Field testing of HDTV at 199 sites in the United States was completed August 14, 1994. The first public HDTV broadcast in

8463-636: Was later converted to digital television with video compression . In 1949, France started its transmissions with an 819 lines system (with 737 active lines). The system was monochrome only and was used only on VHF for the first French TV channel. It was discontinued in 1983. In 1958, the Soviet Union developed Тransformator ( Russian : Трансформатор , meaning Transformer ), the first high-resolution (definition) television system capable of producing an image composed of 1,125 lines of resolution aimed at providing teleconferencing for military command. It

8556-484: Was staged. GM hired investigators from Failure Analysis Associates (FaAA, now Exponent ) to study the footage; FaAA investigators discovered while reviewing the video that smoke had actually started to expel from the fuel tank six frames before the actual impact occurred. Acting on a tip from someone involved with the Dateline crash test, investigators with FaAA searched through 22 junkyards in Indiana before finding

8649-534: Was widely adopted as the video coding standard for HDTV implementations, enabling the development of practical digital HDTV. Dynamic random-access memory ( DRAM ) was also adopted as framebuffer semiconductor memory, with the DRAM semiconductor industry 's increased manufacturing and reducing prices important to the commercialization of HDTV. Since 1972, International Telecommunication Union 's radio telecommunications sector ( ITU-R ) had been working on creating
