120-497: Programa Silvio Santos is a Brazilian variety program presented and created by Silvio Santos and broadcast by Sistema Brasileiro de Televisão (SBT). Airing from June 2, 1963, it is the second oldest television program in Brazil. It is the main attraction of SBT on Sundays. The program airs from 20:00 until midnight. It is best known as a program of sequential segments, game shows, pranks and its famous airplanes of money. In 1993,

240-455: A Jeffree cell to modulate a focused light beam from a mercury lamp . It used 39 vacuum tubes in its electronic circuits, and consumed around 1,000 Watts. Although producing impressive results and reaching the marketplace, the receiver was very expensive, costing around twice as much as a cathode-ray television. It was not a commercial success, and television transmissions in the UK were suspended for

360-415: A 2 by 2.5 inches (5 by 6 cm) screen (width by height). The large receiver had a screen 24 by 30 inches (61 by 76 cm) (width by height). Both sets were capable of reproducing reasonably accurate, monochromatic moving images. Along with the pictures, the sets also received synchronized sound. The system transmitted images over two paths: first, a copper wire link from Washington to New York City, then

480-551: A ball has struck a bat. Laser lighting display techniques are combined with computer emulation in the LaserMAME project. It is a vector -based system, unlike the raster displays thus-far described. Laser light reflected from computer-controlled mirrors traces out images generated by classic arcade software which is executed by a specially modified version of the MAME emulation software . The most common method for creating

600-498: A brief time in the late 1980s, the show was replaced with The American Radio Company of the Air , also hosted and created by Keillor, was set in a more urban environment and likewise was based on old-time radio; its short run eventually morphed into a revival of A Prairie Home Companion ). In 2016, following Keillor's retirement, Chris Thile took over the program and, over the course of the next year, transformed it into Live from Here ,

720-516: A bunch of head-banging, beer-crushing rock jocks blew up a pile of disco records in the Chicago White Sox outfield . If any art form truly encapsulates the entirety of '70s culture, it is the variety show. After all, the variety show was not an art form, it was all art forms. A variety show packed sketch comedy, dance choreography, guest celebrities and concert performances (okay, lip-synching) into one anything-goes show. A variety show

840-471: A charity or cause. The Jerry Lewis MDA Telethon was one of the best known telethons in the US, but it too was eventually canceled after several years of shortening (originally over 21 hours, by the time of its last telecast in 2014, by which point Lewis had been gone from the telethon several years, it was down to two hours). Another popular telethon, for United Cerebral Palsy , ended its run in 1998 shortly after

960-503: A cooking show or a talent competition but end in various results. Iran had a private television company that had broadcast Iran television network channel before national television, it aired variety shows. Variety programming has remained one of the dominant genres of television programming. While Japanese variety shows are famous abroad for their wild stunts, they vary from talk shows to music shows, from tabloid news shows to skit comedy. The prominent use of telop on screen has created

1080-788: A day, three days a week, with sound/visions frequencies being 6.7 m (22 ft) and 6.985 m (22.92 ft). Likewise, a 180-line system that Compagnie des Compteurs (CDC) installed in Paris was tested in 1935, and a 180-line system by Peck Television Corp. started in 1935 at station VE9AK in Montreal , Quebec, Canada. John Baird's 1928 color television experiments had inspired Goldmark's more advanced field-sequential color system . The CBS color television system invented by Peter Goldmark used such technology in 1940. In Goldmark's system, stations transmit color saturation values electronically; however, mechanical methods are also used. At

1200-461: A fast-paced setting, with scenes repeating or fast forwarded. Another popular variety show in Taiwan was Kangsi Coming (2004–2016). It was famous for its bantering, which was scripted. The first Cantonese variety show to become a major success was Hong Kong's Enjoy Yourself Tonight , which first aired in 1967 and ran for 27 years. In Hong Kong, variety shows are often combined with elements of

1320-435: A female audience and produced by Elle chief editor Daisy de Galard. Each episode of Dim Dam Dom was hosted in an all-white studio set by a different speakerine (a female continuity announcer), usually a popular actress or singer like Françoise Hardy , Marie Laforêt , Geraldine Chaplin , France Gall , Jane Birkin , Françoise Fabian , Romy Schneider . Variety shows with an emphasis on comedy sketches were popular in

1440-838: A few shows (such as Hee Haw and The Lawrence Welk Show ) surviving and moving into first-run syndication . Variety shows continued to be produced in the 1970s, with most of them stripped down to only music and comedy. Popular variety shows that ran in the 1970s include The Flip Wilson Show (1970–1974), The Sonny & Cher Comedy Hour (1971–1977, in various incarnations), The Bobby Goldsboro Show (1973–1975), The Hudson Brothers' Razzle Dazzle Show (1974–1975), The Midnight Special (1973–1981), Don Kirshner's Rock Concert (1973–1981), The Mac Davis Show (1974–1976), Tony Orlando and Dawn (1974–1976), Saturday Night Live (1975–present), Donny & Marie (1976–1979), The Muppet Show (1976–1981), and Sha Na Na (1977–1981). Of all of these, only Saturday Night Live remains on

1560-412: A few years, reruns of most of those shows (except The Flip Wilson Show ) were discontinued. Similarly, CMT held the rights to Hee Haw but broadcast very few episodes, opting mainly to hold the rights to allow them to create performance videos from the episodes to be shown in its video blocks. The current rights holder of Hee Haw , RFD-TV , has been more consistent broadcasting complete episodes of

1680-412: A five-foot (1.5 m) square screen. By 1927 he achieved an image of 100 lines, a resolution that was not surpassed until 1931 by RCA, with 120 lines. Because only a limited number of holes could be made in the disks, and disks beyond a certain diameter became impractical, image resolution on mechanical television broadcasts was relatively low, ranging from about 30 lines up to 120 or so. Nevertheless,

1800-458: A flurry of new variety shows with rural appeal: The Johnny Cash Show (1969–1971), The Jim Nabors Hour (1969–1971), The Glen Campbell Goodtime Hour (1969–1972) and Hee Haw (1969–1992). Entertainers with less successful variety shows in the 1960s include Judy Garland and Sammy Davis Jr. Some consider disco to be the boiled-down essence of Seventies pop culture . But that doesn't quite cover it. Not everyone liked disco. In fact,

1920-522: A flying spot approach. A few mechanical TV systems could produce images several feet or meters wide and of comparable quality to the CRT televisions that were to follow. CRT technology at that time was limited to small, low-brightness screens. One such system was developed by Ulises Armand Sanabria in Chicago. By 1934, Sanabria demonstrated a projection system which had a 30-foot (9.1 m) image. Perhaps

2040-408: A high sensitivity infrared photo receptor (usually cooled to increase sensitivity), but instead of conventional lenses, these systems use rotating prisms to provide a 525 or 625 line standard video output. The optical parts are made from germanium, because glass is opaque at the wavelengths involved. Similar cameras have also found a role in sporting events where they are able to show (for example) where

2160-425: A horizontal image. Baird's "zone television" is an early example of rethinking his extremely narrow screen format. For entertainment and most other purposes, even today, landscape remains the more practical shape. In the days of commercial mechanical television transmissions, a system of recording images (but not sound) was developed, using a modified gramophone recorder. Marketed as " Phonovision ", this system, which

2280-412: A more streamlined musical variety series. Live from Here , which moved to New York City in 2019, was cancelled due to budget cuts in 2020. Improvisational comic Wayne Brady , coming off his successful appearances on the panel game Whose Line Is It Anyway? , launched an eponymous variety show in 2001, which aired on ABC. The Wayne Brady Show lasted only one summer season in its variety format; when

2400-468: A music hall artist of that period. The audience was also encouraged to dress in period costume in a similar fashion. Other long-running British variety shows that originated in the 1950s include Tonight at the London Palladium (1955–1969), The Black and White Minstrel Show (1958–1978), The White Heather Club (1958–1968) and Royal Variety Performance (an annual event televised since

2520-722: A parody of rightwing pundits). The Richard Bey Show combined the variety show with the tabloid talk show , not only having its guests talk about their problems but also having them participate in absurdist games, and Sally Jesse Raphael was known for occasionally having music and fashion in the show, especially drag and gender-bending performances. American sketch comedy series such as Saturday Night Live , In Living Color , Almost Live! (and its successor Up Late NW ), MADtv , and SCTV also contain variety show elements, particularly musical performances and comedy sketches. The most obvious difference between shows such as Saturday Night Live and traditional variety shows

2640-493: A peak of 240-lines of resolution on BBC television broadcasts in 1936 though the mechanical system did not scan the televised scene directly. Instead a 17.5 mm film was shot, rapidly developed and then scanned while the film was still wet. An American inventor, Charles Francis Jenkins also pioneered the television. He published an article on "Motion Pictures by Wireless" in 1913, but it was not until December 1923 that he transmitted moving silhouette images for witnesses, and it

2760-440: A price of £15 (US$ 45) per selenium cell, he estimated that a 4,000 cell system would cost £60,000 (US$ 180,000), and a 10,000 cell mechanism capable of reproducing "a scene or event requiring the background of a landscape" would cost £150,000 (US$ 450,000). Ruhmer expressed the hope that the 1910 Brussels Exposition Universelle et Internationale would sponsor the construction of an advanced device with significantly more cells, as

2880-590: A radio link from Whippany, New Jersey . Comparing the two transmission methods, viewers noted no difference in quality. Subjects of the telecast included Secretary of Commerce Herbert Hoover . A flying-spot scanner beam illuminated these subjects. The scanner that produced the beam had a 50-aperture disk. The disc revolved at a rate of 18 frames per second, capturing one frame about every 56 milliseconds . (Today's systems typically transmit 30 or 60 frames per second, or one frame every 33.3 or 16.7 milliseconds respectively.) Television historian Albert Abramson underscored

3000-526: A rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode-ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) and LED displays are now used to create and display television pictures. Mechanical-scanning methods were used in

3120-467: A run on CBS in the early 2000s during the reality television boom; The Gong Show , which reached its peak in the 1970s but has had occasional revivals since then; and the worldwide Got Talent franchise. The variety show format also continued in America in the form of the telethon , which feature variety entertainment (often music) interspersed with appeals for viewers to make donations to support

3240-574: A series of variety shows that collectively ran from 1948 to 1969, followed by variety specials that ran until 1994. Shorter-lived variety shows during this period include The Frank Sinatra Show (1950–1952), The Jimmy Durante Show (1954–1956) and a different The Frank Sinatra Show (1957–1958). In the UK The Good Old Days —which ran from 1953 to 1983—featured modern artists performing dressed in late Victorian /Early Edwardian costume, either doing their own act or performing as

3360-467: A showcase for the exposition. However, the estimated expense of £250,000 (US$ 750,000) proved to be too high. The publicity generated by Ruhmer's demonstration spurred two French scientists, Georges Rignoux and A. Fournier in Paris, to announce similar research that they had been conducting. A matrix of 64 selenium cells , individually wired to a mechanical commutator , served as an electronic retina . In

3480-461: A small or large moving image to fit into a channel less than 40 kHz wide (modern TV systems usually have a channel about 6 MHz wide, 150 times larger). Also associated with this is slow-scan TV – although that typically used electronic systems utilising the P7 CRT until the 1980s and PCs thereafter. There are three known mechanical monitor forms: two fax printer-like monitors made in

3600-612: A style that has influenced variety programming across Asia. One of the most popular variety shows in Japan includes Downtown no Gaki no Tsukai . In South Korea , the hugely popular show Infinite Challenge , has been broadcast by MBC from 2005 to 2018, was a new model of this, called "Real Variety Show". It combined comedy and variety scenes including unscripted stunts and special guest stars while taking place in various settings. Although many variety shows have existed in Korea long before

3720-420: A system using high power lasers is used in laser video projectors, with resolutions as high as 1024 lines and each line containing over 1,500 points. Such systems produce, arguably, the best quality video images. They are used, for instance, in planetariums . Mechanical techniques are also used in long wave infrared cameras used in military applications such as night vision for fighter pilots. These cameras use

3840-586: A television system with a 40-line resolution that employed a Nipkow disk scanner and CRT display at Hamamatsu Industrial High School in Japan. This prototype is still on display at the Takayanagi Memorial Museum in Shizuoka University , Hamamatsu Campus. By 1927, he improved the resolution to 100 lines, which was unrivaled until 1931. By 1928, he was the first to transmit human faces in half-tones. His work had an influence on

3960-605: A variety show starring SNL performer Maya Rudolph . Like Rosie Live , the broadcast was intended to be a one-off special, but with the possibility of additional episodes depending on its performance. The special won its time slot, due mainly to a strong lead-in, and spawned the May 2016 premiere of Maya & Marty , adding fellow SNL cast member Martin Short ; under that format, Maya & Marty lasted six episodes. Earlier that season, NBC aired Best Time Ever , an adaptation of

4080-480: A vertical "portrait" image made more sense to Baird than a horizontal "landscape" image. Baird chose a shape three units wide by seven high. This shape is only about half as wide as a traditional portrait and close in proportion to a typical doorway. Instead of entertainment television, Baird might have had point-to-point communication in mind. Another television system followed that reasoning. The 1927 system developed by Herbert E. Ives at AT&T's Bell Laboratories

4200-504: Is Broadway meets Solid Gold meets Saturday Night Live meets Saturday morning . MeTV In 1970 and 1971, the American TV networks, CBS especially, conducted the so-called " rural purge ", in which shows that appealed to more rural and older audiences were canceled as part of a greater focus on appealing to wealthier demographics. Many variety shows, including long-running ones, were canceled as part of this "purge," with

The genre proliferated during the Golden Age of Television , generally considered to be roughly 1948 to 1960. Many of these Golden Age variety shows were spin-offs or adaptations of previous radio variety shows. From 1948 to 1971 The Ed Sullivan Show was one of CBS 's most popular television series. Using his no-nonsense approach, host Ed Sullivan

4440-403: Is the lack of a single lead host (or hosts) and a large ensemble cast . SNL has used different guest hosts ever since its inception. Televised talent shows have a variety show element, in that they feature a variety of different acts. Examples of US talent shows that feature entertainers from a broad variety of disciplines include Star Search , which had a run in the 1980s in syndication and

Early Cathode-Ray Television tube displays were small in size. The 'Scophony' television receiver of 1938, an advanced television receiver that used a mechanical display, was capable of displaying a 405-line picture (compatible with

4680-564: The Franklin Institute in Philadelphia in 1934, was rapidly overtaking mechanical television. Farnsworth's system was first used for broadcasting in 1936, reaching 400 to more than 600 lines with fast field scan rates, along with competing systems by Philco and DuMont Laboratories . In 1939, RCA paid Farnsworth $ 1 million for his patents after ten years of litigation, and RCA began demonstrating all-electronic television at

4800-531: The photoconductivity of the element selenium in 1873, laying the groundwork for the selenium cell which was used as a pickup in most mechanical scan systems. In 1885, Henry Sutton in Ballarat, Australia designed what he called a telephane for transmission of images via telegraph wires, based on the Nipkow spinning disk system, selenium photocell , Nicol prisms and Kerr effect cell. Sutton's design

4920-599: The "landscape" orientation – these terms coming from the concepts of portrait and landscape in art  – that is common today. The position of a framing mask before the Nipkow disk determines the scan line orientation. Placement of the framing mask at the left or right side of the disk gives vertical scan lines. Placement at the top or bottom of the disk gives horizontal scan lines. Baird's earliest television images had very low definition. These images could only show one person clearly. For this reason,

7560-588: The design practical. Scottish inventor John Logie Baird in 1925 built some of the first prototype video systems, which employed the Nipkow disk . On March 25, 1925, Baird gave the first public demonstration of televised silhouette images in motion, at Selfridge's Department Store in London. Since human faces had inadequate contrast to show up on his primitive system, he televised a ventriloquist's dummy named "Stooky Bill" talking and moving, whose painted face had higher contrast. By January 26, 1926, he demonstrated

7680-687: The disc to the NTSC system. In Col-R-Tel, the electronics provide the saturation values (chroma). These electronics cause chroma values to superimpose over brightness (luminance) changes of the picture. The disc paints the hues (color) over the picture. A few years after Col-R-Tel, the Apollo Moon missions also adopted field-sequential techniques. The lunar color cameras all had color wheels. These Westinghouse and later RCA cameras sent field-sequential color television pictures to Earth. The Earth receiving stations included electronic equipment that converted

8160-402: The earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by Scottish inventor John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. However the technology never produced images of sufficient quality to become popular with

8280-709: The early top performers on British television and radio did an apprenticeship either in stage variety, or during World War II in Entertainments National Service Association (ENSA). In the UK, the ultimate accolade for a variety artist for decades was to be asked to do the annual Royal Command Performance at the London Palladium theatre, in front of the monarch. Later known as the Royal Variety Performance (from 1919), it continues today. In

8400-447: The first programs to be featured on television during the experimental mechanical television era. Variety shows hosted by Helen Haynes and Harriet Lee are recorded in contemporary newspapers in 1931 and 1932; because of technical limits of the era, no recordings of either show have been preserved. After World War II , the genre again was an early favorite of the burgeoning electronic television industry; Hour Glass , dating to 1946,

8520-488: The first shore-to-ship transmission. In 1929, he became involved in the first experimental mechanical television service in Germany. In November of the same year, Baird and Bernard Natan of Pathé established France's first television company, Télévision- Baird -Natan. In 1931, he made the first outdoor remote broadcast, of The Derby . In 1932, he demonstrated ultra-short wave television. Baird's mechanical system reached

8640-512: The flying spot method until 1935, and German television used flying spot methods as late as 1938. However, flying spot techniques remained in use in many applications after the demise of mechanical television. The German inventor Manfred von Ardenne designed a flying spot scanner with a CRT as the light source, and CRT-based flying spot scanners became a common technique for telecine . In the 1950s, DuMont marketed Vitascan , an entire flying-spot color studio system. Laser scanners continue to use

8760-597: The format faded in popularity in prime time, it thrived in American late-night TV. Night-time variety shows eventually evolved into late-night talk shows , which combine variety entertainment (primarily comedy and live music) with the aspects of a talk show (such as interviews with celebrities). The Emmy Awards academy considers the two genres to be related closely enough that, until 2015, the Primetime Emmy Award for Outstanding Variety, Music or Comedy Series

8880-476: The genre arose in the late 1980s and early 1990s. Variety shows from this era included Dolly (starring Dolly Parton ), which ran for 23 episodes on ABC during the 1987–88 season; The Tracey Ullman Show which aired on Fox from April 1987 through May 1990; a revival of The Smothers Brothers Comedy Hour from 1988 to 1989; a revival of The Carol Burnett Show , which was broadcast by CBS for nine episodes in 1991 (following up on Carol & Company on NBC

9000-546: The image quality of 30-line transmissions steadily improved with technical advances, and by 1933 the UK broadcasts using the Baird system were remarkably clear. A few systems ranging into the 200-line region also went on the air. 180-lines broadcast tests were carried out by the Reichs-Rundfunk-Gesellschaft in 1935, with a 16 kW (21 hp) transmitter in Berlin . Transmissions lasted 90 minutes

9120-475: The later work of Vladimir K. Zworykin . In Japan he is viewed as the man who completed the first all-electronic television. His research in creating a production model was halted by the US after Japan lost World War II . Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on April 7, 1927. The reflected-light television system included both small and large viewing screens. The small receiver had

9240-521: The money of the time. Inexpensive adapters allowed owners of black-and-white NTSC television sets to receive color telecasts. The most prominent of these adapters is Col-R-Tel, a 1955 NTSC to field-sequential converter. This system operates at NTSC scanning rates, but uses a disc like the obsolete CBS system had. The disc converts the black-and-white set to a field-sequential set. Meanwhile, Col-R-Tel electronics recover NTSC color signals and sequence them for disc reproduction. The electronics also synchronize

9360-414: The most popular variety shows on French television , including Le Sacha Show (1963–1971) hosted by Sacha Distel , Top à... (1972–1974), Numéro Un (1975–1982) and a lot of television specials presented by various famous singers ( Johnny Hallyday , Sylvie Vartan , Claude François , Petula Clark ). From 1965 to 1970 was also aired Dim Dam Dom , a modern, playful and sophisticated show intended for

9480-481: The point where the spot fell reflected varying amounts of light, which was converted to a proportionally varying electronic signal by the photoelectric cells. To achieve adequate sensitivity, instead of a single cell, a number of photoelectric cells were used. Like mechanical television itself, flying spot technology grew out of phototelegraphy (facsimile). This scanning method began in the 19th century. The flying spot method has two disadvantages: In 1928, Ray Kell from

9600-405: The predominant form of light entertainment during the Golden Age of Radio from the late 1920s through the 1940s; such radio shows typically included a house vocalist, music from the house band , a stand-up monologue and a short comedy sketch . Variety shows centered on running comedy sketches with recurring characters eventually evolved into sitcoms (situation comedies). Variety shows were among

9720-409: The previous year); and Showtime 's The Super Dave Osborne Show hosted by Bob Einstein from 1987 to 1991 (itself a spinoff of John Byner 's Bizarre , which ran from 1980 to 1986). By the 1990s, networks had given up on the format; after initially promising Phil Hartman his own variety show, NBC backed out of the agreement believing a variety show could no longer succeed. By the 21st century

9840-535: The program was even awarded the title of "Oldest Program of the Brazilian TV" by Guinness World Records , shortly after losing the title to the Mosaico na TV , broadcast since July 16, 1961. In 2015, the program's 'Câmera Escondida' segment with a clown pieing shoppers on a mall escalator went viral internationally, particularly through Twitter . This led many online to question its legitimacy as to whether

9960-504: The program; RFD-TV also airs numerous other country -style variety shows from the 1960s and 1970s up through the present day, in a rarity for modern television. Another notable exception is The Lawrence Welk Show , which has been frequently broadcast in reruns on the Public Broadcasting Service (PBS) since 1986. The Danny Kaye Show returned to television in 2017 with reruns on Jewish Life Television (and, in

10080-454: The proliferation of multichannel television and evolving viewer tastes have affected the popularity of variety shows in the United States. Despite this, their influence has still had a major effect on late night television whose late-night talk shows and NBC 's variety series Saturday Night Live (which originally premiered in 1975) have remained popular fixtures of American television. The live entertainment style known as music hall in

10200-541: The public. Mechanical-scan systems were largely superseded by electronic-scan technology in the mid-1930s, which was used in the first commercially successful television broadcasts which began in the late 1930s. In the U.S., experimental stations such as W2XAB in New York City began broadcasting mechanical television programs in 1931 but discontinued operations on February 20, 1933, until returning with an all-electronic system in 1939. A mechanical television receiver

10320-579: The raw colour video signals into the NTSC standard. The advancement of vacuum tube electronic television (including image dissectors and other camera tubes and CRTs for the reproducer) marked the beginning of the end for mechanical systems as the dominant form of television. Mechanical TV usually only produced small images. It was the main type of TV until the 1930s. Vacuum tube television, first demonstrated in September 1927 in San Francisco by Philo Farnsworth , and then publicly by Farnsworth at

10440-406: The receiver, a type of Kerr cell modulated the light and a series of variously angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8 x 8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image

10560-506: The regularly scheduled variety shows that spawned them by several years. Also, Barbara Mandrell Christmas special. Christmas variety specials' popularity continued into the 1990s, before starting to wane in the 2000s. Nevertheless, the tradition has continued. Entertainers who have hosted Christmas variety specials in the 21st century include Kid Rock , Nick Lachey and Jessica Simpson , Carrie Underwood , Lady Gaga , Michael Buble , Bill Murray , Gwen Stefani , and Darci Lynne . Though

10680-530: The scanned part. Kell's photocells couldn't discriminate reflections off Smith (from the AC scanning beam) from the flat, DC light from the floodlamps. The effect is very similar to extreme overexposure in a still camera: The scene disappears, and the camera records a flat, bright light. If used in favorable conditions, however, the picture comes out correctly. Similarly, Kell proved that outdoors in favorable conditions, his scanner worked. The BBC television service used

10800-472: The short lived Micallef Tonight and The Sideshow . In Brazil variety shows are referred to as a show de auditório (lit. "auditorium show"). Among the longest-running variety shows on Brazilian television have been SBT 's Programa Silvio Santos (1963–present), which was originally hosted by SBT's owner and founder Silvio Santos (and is presently hosted by his daughter Patricia Abravanel ), and TV Globo 's Domingão do Faustão (1989–2021), which

10920-461: The show returned the next year in syndication, it had been reformatted as a talk show, under which format it ran until 2004. Fox's Osbournes Reloaded , a variety show featuring the family of rocker Ozzy Osbourne , was canceled after only one episode had been telecast in 2009. More than two dozen affiliates refused to telecast the first episode of the show. This series had been slated for a six-episode run. NBC has made repeated attempts at reviving

11040-470: The show used paid actors, or random members of the public. Contestant Lucas Nogueira confirmed that the shoppers were paid actors, and said they were told to walk around the mall for a comedy show, and were told that something would happen to them, but were not told exactly what. Variety program While still widespread in some parts of the world, such as in the United Kingdom with the Royal Variety Performance , and South Korea with Running Man ,

11160-576: The significance of the Bell Labs demonstration: "It was in fact the best demonstration of a mechanical television system ever made to this time. It would be several years before any other system could even begin to compare with it in picture quality." In 1928, General Electric launched their own experimental television station W2XB , broadcasting from the GE plant in Schenectady, New York. The station

11280-474: The star in a set meant to look like their home, welcoming singers and other guests to perform duets of Christmas songs . The popularity of these Christmas shows outlasted that of weekly variety shows. In 1973, for example, even as variety shows were starting to fade in popularity, variety Christmas specials hosted by Williams and Como both attracted an enormous 40% of the American television audience. Williams's and Johnny Cash 's annual Christmas specials outlasted

11400-663: The succeeding years. Recently many other TV networks are different formats of variety. ABS-CBN's It's Showtime has also shown great popularity and interest to Filipino viewers. Siempre en Domingo premiered in 1969 with Raúl Velasco hosting. It became Mexico's longest-running variety series, remaining on Televisa until 1998. Other long-running variety shows, most of which have been Televisa productions, have included La Carabina de Ambrosio , Anabel , Al Fin de Semana , Silvia y Enrique , La Parodia , Muevete , Desmadruga2 , and Sabadazo. . Most, if not all, of Televisa's variety shows have aired in other countries, including

11520-443: The television systems of Ernst Alexanderson , Frank Conrad , Charles Francis Jenkins , William Peck and Ulises Armand Sanabria . ) These inventors realized that television is about relationships between people. From the very beginning, these inventors allowed picture space for two-shots. Soon, images increased to 60 lines or more. The camera could easily photograph several people at once. Then even Baird switched his picture mask to

11640-478: The then 405-line television system used in the United Kingdom) on a display that was 24-inches wide and 20-inches high. A version intended for theater audiences had a 6 feet wide display. It was also capable of being set up for the US 441-line television system . For 405 lines, it used a high-speed scanner running at 30,375 r.p.m. and a low speed mirror drum running at around 250 r.p.m., in conjunction with

11760-435: The transmission of image of a face in motion by radio. This is widely regarded as being the world's first public television demonstration. Baird's system used the Nipkow disk for both scanning the image and displaying it. A brightly illuminated subject was placed in front of a spinning Nipkow disk set with lenses which swept images across a static photocell. The thallium sulphide (Thalofide) cell, developed by Theodore Case in

11880-455: The transmission of simple images over a telephone wire from the Palace of Justice at Brussels to the city of Liege, a distance of 115 km (71 mi). This demonstration was described at the time as "the world's first working model of television apparatus". The limited number of elements meant his device was only capable of representing simple geometric shapes, and the cost was very high; at

12000-664: The transmitter and receiver. Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on August 24, 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others. However, it was the 1907 invention of the first amplifying vacuum tube , the triode , by Lee de Forest , that made

12120-497: The transmitting camera, a mechanical disc filters hues (colors) from reflected studio lighting. At the receiver, a synchronized disc paints the same hues over the CRT. As the viewer watches pictures through the color disc, the pictures appear in full color. Later, simultaneous color systems superseded the CBS-Goldmark system, but mechanical color methods continued to find uses. Early color sets were very expensive: over $ 1,000 in

12240-520: The variety format since the late 2000s (the network's last successful variety series, Michael Nesmith 's short-lived but influential Television Parts , was broadcast in the summer of 1985) . A pilot episode for Rosie Live was telecast the day before Thanksgiving Day in 2008 and, after receiving middling ratings and extremely poor reviews, was not picked up for its originally planned run in January 2009. In May 2014, NBC aired The Maya Rudolph Show ,

12360-482: The variety show format was practically extinct, due largely to changing tastes and the fracturing of media audiences (caused by the proliferation of cable and satellite television ) that makes a multiple-genre variety show impractical. Even reruns of variety shows have generally not been especially widespread; TV Land briefly broadcast repeats of some variety shows (namely The Ed Sullivan Show and The Sonny & Cher Comedy Hour ) upon its launch in 1996, but within

12480-441: The video signal was the "flying spot scanner", developed as a remedy for the low sensitivity that photoelectric cells had at the time. Instead of a television camera that took pictures, a flying spot scanner projected a bright spot of light that scanned rapidly across the subject scene in a raster pattern, in a darkened studio. The light reflected from the subject was picked up by banks of photoelectric cells and amplified to become

12600-430: The video signal. In the scanner the narrow light beam was produced by an arc lamp shining through the holes in a spinning Nipkow disk. Each sweep of the spot across the scene produced a "scan line" of the picture. A single "frame" of the picture was typically made up of 24, 48, or 60 scan lines. The scene was typically scanned 15 or 20 times per second, producing 15 or 20 video frames per second. The varying brightness of

12720-566: Was a large-screen television system and the most advanced television of its day. The Ives 50-line system also produced a vertical "portrait" picture. Since AT&T intended to use television for telephony, the vertical shape was logical: phone calls are usually conversations between just two people. A picturephone system would depict one person on each side of the line. Meanwhile, in the US, Germany and elsewhere, other inventors planned to use television for entertainment purposes. These inventors began with square or "landscape" pictures. (For example,

12840-489: Was also called a televisor . The first mechanical raster scanning techniques were developed in the 19th century for facsimile , the transmission of still images by wire. Alexander Bain introduced the facsimile machine in 1843 to 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. The first practical facsimile system, working on telegraph lines, was developed and put into service by Giovanni Caselli from 1856 onward. Willoughby Smith discovered

12960-403: Was broadcasting Smith's speech. The rehearsal went well, but then the real event began. The newsreel cameramen switched on their floodlights. Unfortunately for Kell, his scanner only had a 1 kW lamp inside it. The floodlights threw much more light on Governor Smith. These floods simply overwhelmed Kell's imaging photocells. In fact, the floods made the unscanned part of the image as bright as

13080-432: Was common on many early color television systems before the shadow mask CRT provided a practical method for producing a simultaneous color image. Another place where high-quality imagery is produced by opto-mechanics is the laser printer , where a small rotating mirror is used to deflect a modulated laser beam in one axis while the motion of the photoconductor provides the motion in the other axis. A modification of such

13200-413: Was hosted by Fausto Silva until he departed the network to host a short-lived variety show on Rede Bandeirantes . Two notable Taiwanese variety shows are Guess (1996–2012) and 100% Entertainment (1997–present). East Asian variety programs are known for their constant use of sound effects, on-screen visuals and comedic bantering. Many of the shows are presented in a live-like presentation in

13320-531: Was instrumental in bringing many acts to prominence in the United States, including Elvis Presley and The Beatles . One year after Sullivan's premiere, Music & the Spoken Word first aired on television. Having carried over from an already 20-year run on radio, the series airs a program of religious music, messages, and occasional interviews, and remains the longest-running variety show in U.S. television history. " The Arthur Murray Party " (1950–1960)

13440-458: Was never fully perfected, proved to be complicated to use as well as quite expensive, yet managed to preserve a number of early broadcast images that would otherwise have been lost. Scottish computer engineer Donald F. McLean has painstakingly reconstructed the analogue playback technology required to view these recordings, and has given lectures and presentations on his collection of mechanical television recordings made between 1925 and 1933. Among

13560-676: Was on June 13, 1925, that he publicly demonstrated synchronized transmission of silhouette pictures. In 1925 Jenkins used Nipkow disk and transmitted the silhouette image of a toy windmill in motion, over a distance of five miles (8 km) from a naval radio station in Maryland to his laboratory in Washington, D.C., using a lensed disk scanner with a 48-line resolution. He was granted the U.S. patent No. 1,544,156 (Transmitting Pictures over Wireless) on June 30, 1925 (filed March 13, 1922). On December 25, 1925, Kenjiro Takayanagi demonstrated

13680-555: Was only the 22nd-most watched show of the year. By 1980 viewer interest in TV variety shows was rapidly waning. Most of the few new variety programs being produced were of remarkably poor quality (for instance, the infamous Pink Lady and Jeff ), hastening the format's demise, though a few moderately successful shows remained, such as Barbara Mandrell & the Mandrell Sisters (November 1980 to June 1982). A brief revival of

13800-515: Was open to any of these types of show; in 2015, the academy separated late-night talk shows and sketch comedy series into separate categories. During Johnny Carson 's tenure on The Tonight Show on NBC from 1962 to 1992, the show dominated late night ratings, and the other networks attempted late-night talk shows only sporadically. This changed with Carson's retirement, and other networks began to air their own talk show competitors, starting with Late Show with David Letterman on CBS in 1993. As of

13920-646: Was popularly known as " WGY Television", named after the GE owned radio station WGY . The station eventually converted to an all-electronic system in the 1930s and in 1942, received a commercial license as WRGB . The station is still operating today. Meanwhile, in the Soviet Union , Léon Theremin had been developing a mirror drum-based television, starting with 16 lines resolution in 1925, then 32 lines and eventually 64 using interlacing in 1926, and as part of his thesis on May 7, 1926, he electrically transmitted and then projected near-simultaneous moving images on

14040-530: Was published internationally in 1890. An account of its use to transmit and preserve a still image was published in the Evening Star in Washington in 1896. The first demonstration of the instantaneous transmission of images was made by a German physicist, Ernst Ruhmer , who arranged 25 selenium cells as the picture elements for a television receiver. In late 1909 he successfully demonstrated in Belgium

14160-468: Was transmitted "several times" each second. In 1911, Boris Rosing and his student Vladimir Zworykin created a system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the " Braun tube" ( cathode-ray tube or "CRT") in the receiver. Moving images were not possible because, in the scanner, "the sensitivity was not enough and the selenium cell

14280-415: Was very laggy". As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884. This was a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of the image. Although he never built a working model of the system, Nipkow's spinning-disk " image rasterizer " was the key mechanism used in most mechanical scan systems, in both

14400-516: Was wildly popular and one of only 5 shows in the history of television to appear on all four major networks at the same time. The premise was a large dance party hosted by Kathryn Murray and Arthur Murray that showcased a new dance and a celebrity guest along with dozens of professional dancers. The show also hosted the only television appearance of Buddy Holly and The Crickets . The Lawrence Welk Show (1955–1982) would go on to become one of U.S. television's longest-running variety shows; based on
