He began work as an employee benefits consultant and later a health insurance broker , writing once he was able to support himself and his family financially. Hoping to become a screenwriter , Knauf's first draft of Carnivàle , written in 1992, was 180 pages long and twice the length of the average feature film . Convinced the screenplay could not work as either
474-458: A patent interference suit against Farnsworth. The U.S. Patent Office examiner disagreed in a 1935 decision, finding priority of invention for Farnsworth against Zworykin. Farnsworth claimed that Zworykin's 1923 system could not produce an electrical image of the type to challenge his patent. Zworykin received a patent in 1928 for a color transmission version of his 1923 patent application. He also divided his original application in 1931. Zworykin
632-478: A resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p , 1080i and 720p . Since 2010, with the invention of smart television , Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Prime Video , iPlayer and Hulu . In 2013, 79% of the world's households owned
790-618: A transistor -based UHF tuner . The first fully transistorized color television in the United States was the Quasar television introduced in 1967. These developments made watching color television a more flexible and convenient proposition. In 1972, sales of color sets finally surpassed sales of black-and-white sets. Color broadcasting in Europe was not standardized on the PAL format until
948-467: A tuner for receiving and decoding broadcast signals. A visual display device that lacks a tuner is correctly called a video monitor rather than a television. The television broadcasts are mainly a simplex broadcast meaning that the transmitter cannot receive and the receiver cannot transmit. The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. The first documented usage of
1106-483: A 1925 demonstration, the image was dim, had low contrast and poor definition, and was stationary. Zworykin's imaging tube never got beyond the laboratory stage. However, RCA, which acquired the Westinghouse patent, asserted that the patent for Farnsworth's 1927 image dissector was written so broadly that it would exclude any other electronic imaging device. Thus, based on Zworykin's 1923 patent application, RCA filed

#17327914797511896-402: A TV system with a 40-line resolution that employed a CRT display. This was the first working example of a fully electronic television receiver and Takayanagi's team later made improvements to this system parallel to other television developments. Takayanagi did not apply for a patent. In the 1930s, Allen B. DuMont made the first CRTs to last 1,000 hours of use, one of the factors that led to
2054-683: A camera tube, using the CRT instead as a flying-spot scanner to scan slides and film. Ardenne achieved his first transmission of television pictures on 24 December 1933, followed by test runs for a public television service in 1934. The world's first electronically scanned television service then started in Berlin in 1935, the Fernsehsender Paul Nipkow , culminating in the live broadcast of the 1936 Summer Olympic Games from Berlin to public places all over Germany. Philo Farnsworth gave
2212-605: A co-branded version of InfoSpace to deliver minimal portal content. In mid-2007, NBCi.com began to mirror the main NBC.com website; NBCi.com was eventually redirected to the NBC.com domain in 2010. Only one legacy of this direction remains in the website of then-O&O WCMH-TV in Columbus, Ohio (now owned by Nexstar ), which continues to use the URL "nbc4i.com". NBC has used a number of logos throughout its history; early logos used by
2370-609: A color television combining a traditional black-and-white display with a rotating colored disk. This device was very "deep" but was later improved with a mirror folding the light path into an entirely practical device resembling a large conventional console. However, Baird was unhappy with the design, and, as early as 1944, had commented to a British government committee that a fully electronic device would be better. In 1939, Hungarian engineer Peter Carl Goldmark introduced an electro-mechanical system while at CBS , which contained an Iconoscope sensor. The CBS field-sequential color system

NBC's master feed has not fully converted to 1080p or 2160p ultra-high-definition television (UHD). However, some NBC stations have already begun broadcasting at 1080p via ATSC 3.0 multiplex stations. One notable example is WRAL-TV in Raleigh, North Carolina (a station that re-joined NBC in February 2016), which
3160-764: A fellow of the Royal Society (UK), published a letter in the scientific journal Nature in which he described how "distant electric vision" could be achieved by using a cathode-ray tube, or Braun tube, as both a transmitting and receiving device, he expanded on his vision in a speech given in London in 1911 and reported in The Times and the Journal of the Röntgen Society. In a letter to Nature published in October 1926, Campbell-Swinton also announced
3318-486: A few smaller markets, such as Binghamton, New York ( WBGH-CD ), Jackson, Tennessee ( WNBJ-LD ) and Juneau, Alaska ( KATH-LD ), that do not have enough full-power stations to support a standalone affiliate. In some markets, these stations also maintain digital simulcasts on a subchannel of a co-owned/co-managed full-power television station. Southern New Hampshire receives NBC programming via network-owned WBTS-CD , licensed to serve Nashua ; while nominally licensed as

#17327914797513476-593: A heavily advertised online venture serving as an attempt to launch a web portal . This move saw NBC partner with Xoom.com (not to be confused with the current money transfer service ), e-mail.com, AllBusiness.com , and Snap.com (eventually acquiring all four companies outright; not to be confused with the current-day parent of Snapchat ) to launch a multi-faceted internet portal with e-mail, web hosting, community, chat and personalization capabilities, and news content. Subsequently, in April 2000, NBC purchased GlobalBrain,

5056-471: A production model was halted by the SCAP after World War II . 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, the image quality of 30-line transmissions steadily improved with technical advances, and by 1933
5214-506: A projection screen at London's Dominion Theatre . Mechanically scanned color television was also demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells , amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full-color image. The first practical hybrid system was again pioneered by John Logie Baird. In 1940 he publicly demonstrated
5372-591: 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
5530-616: A resolution that was not surpassed until May 1932 by RCA, with 120 lines. On 25 December 1926, Kenjiro Takayanagi demonstrated 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. His research in creating

NBC programming is available in Mexico through free-to-air affiliates in markets located within proximity to the Mexico–United States border (such as KYMA-DT / Yuma, Arizona ; KGNS-TV / Laredo, Texas ; KTSM / El Paso, Texas ; KVEO / Brownsville, Texas ; and KNSD / San Diego ), whose signals are readily receivable over-the-air in border areas of northern Mexico. Some U.S.-based border affiliates are also available on subscription television providers throughout
5846-641: A signal reportedly to the 60th power or better and showed great promise in all fields of electronics. Unfortunately, an issue with the multipactor was that it wore out at an unsatisfactory rate. At the Berlin Radio Show in August 1931 in Berlin , Manfred von Ardenne gave a public demonstration of a television system using a CRT for both transmission and reception, the first completely electronic television transmission. However, Ardenne had not developed
6004-425: A standard television series or a film, he put it aside, planning to one day adapt it into a novel. Carnivàle evolved as a result of Knauf's childhood fascination with carnivals and his interest in "freaks", due in part to the childhood polio that confined his father to a wheelchair, which Knauf felt his father was defined by.

Founded in 1926 by the Radio Corporation of America , NBC is the oldest of the traditional "Big Three" American television networks and is sometimes referred to as the " Peacock Network " in reference to its stylized peacock logo , which was introduced in 1956 to promote
6478-464: 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 was very laggy". In 1921, Édouard Belin sent the first image via radio waves with his belinograph . By

6636-521: A television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED ), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s they were still CRT , it was only in early 2010s that flat screen TVs have started to overtake CRT TVs once and for all. Major manufacturers announced
6794-484: A television system using fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube. The problem of low sensitivity to light resulting in low electrical output from transmitting or "camera" tubes would be solved with the introduction of charge-storage technology by Kálmán Tihanyi beginning in 1924. His solution was a camera tube that accumulated and stored electrical charges ("photoelectrons") within

12166-470: The Royal Institution the transmission of an image of a face in motion by radio. This is widely regarded as the world's first true public television demonstration, exhibiting light, shade, and detail. 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 that swept images across
12324-560: The Science Museum, South Kensington. In 1928, Baird's company (Baird Television Development Company/Cinema Television) broadcast the first transatlantic television signal between London and New York and 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
12482-508: The Shark , Tutenstein and Time Warp Trio . In May 2006, NBC announced plans to launch a new Saturday morning children's block under the Qubo brand in September 2006. An endeavor originally operated as a joint venture between NBCUniversal , Ion Media Networks , Scholastic Press , Classic Media and Corus Entertainment 's Nelvana unit (Ion acquired the other partners' shares in 2013),
12640-465: The Telechrome continued, and plans were made to introduce a three-gun version for full color. However, Baird's untimely death in 1946 ended the development of the Telechrome system. Similar concepts were common through the 1940s and 1950s, differing primarily in the way they re-combined the colors generated by the three guns. The Geer tube was similar to Baird's concept but used small pyramids with
12798-569: The UK broadcasts using the Baird system were remarkably clear. A few systems ranging into the 200-line region also went on the air. Two of these were the 180-line system that Compagnie des Compteurs (CDC) installed in Paris in 1935 and the 180-line system that Peck Television Corp. started in 1935 at station VE9AK in Montreal . The advancement of all-electronic television (including image dissectors and other camera tubes and cathode-ray tubes for
12956-665: The United States, NBC was formed in 1926 by the Radio Corporation of America (RCA), then owned by General Electric (GE), Westinghouse , AT&T Corporation and United Fruit Company . In 1932, the US Government forced GE to sell RCA and NBC due to antitrust violations. In late 1986, GE regained control of RCA through its $ 6.4 billion purchase of the company. Although it retained NBC, GE immediately closed or sold off most of RCA's other divisions and assets. In 2003, French media company Vivendi merged its entertainment assets with GE, forming NBCUniversal . Comcast purchased
13114-461: The analog and channel-separated signals used by analog television . Due to data compression , digital television can support more than one program in the same channel bandwidth. It is an innovative service that represents the most significant evolution in television broadcast technology since color television emerged in the 1950s. Digital television's roots have been tied very closely to the availability of inexpensive, high performance computers . It
13272-514: The beginning of season two. Television Television ( TV ) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission . Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than " radio broadcasting ," which refers to an audio signal sent to radio receivers . Television became available in crude experimental forms in
13430-561: The channel's slogan "Where the Stars Come Out at Night" was based around. Many NBC News programs were broadcast on NBC Europe, including Dateline NBC , Meet the Press and NBC Nightly News , the latter of which was broadcast simultaneously with the initial U.S. telecast. Today was also initially aired live in the afternoons, but was later broadcast instead the following morning on a more than half-day delay. In 1999, NBC Europe ceased broadcasting in most of Europe outside of Germany;
13588-701: The company's innovations in early color broadcasting . NBC has twelve owned-and-operated stations and has affiliates in every TV market in the United States .

13746-462: The convenience of remote retrieval, the storage of television and video programming now also occurs on the cloud (such as the video-on-demand service by Netflix ). At the beginning of the 2010s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) ( 576i , with 576 interlaced lines of resolution and 480i ) to high-definition television (HDTV), which provides
13904-659: The day after their original broadcast. In addition, NBC.com and certain other partner websites (including Hulu) provide complete back catalogs of most of its current series as well as a limited selection of episodes of classic series from the NBCUniversal Television Distribution program library – including shows not broadcast by NBC during their original runs (including the complete or partial episode catalogs of shows like 30 Rock , The A-Team , Charles in Charge , Emergency! , Knight Rider (both
14062-498: The design of RCA 's " iconoscope " in 1931, the U.S. patent for Tihanyi's transmitting tube would not be granted until May 1939. The patent for his receiving tube had been granted the previous October. Both patents had been purchased by RCA prior to their approval. Charge storage remains a basic principle in the design of imaging devices for television to the present day. On 25 December 1926, at Hamamatsu Industrial High School in Japan, Japanese inventor Kenjiro Takayanagi demonstrated
14220-525: The development of HDTV technology, the MUSE analog format proposed by NHK , a Japanese company, was seen as a pacesetter that threatened to eclipse U.S. electronics companies' technologies. Until June 1990, the Japanese MUSE standard, based on an analog system, was the front-runner among the more than 23 other technical concepts under consideration. Then, a U.S. company, General Instrument, demonstrated
14378-535: The discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. LEDs are being gradually replaced by OLEDs. Also, major manufacturers have started increasingly producing smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s. Television signals were initially distributed only as terrestrial television using high-powered radio-frequency television transmitters to broadcast
14536-421: The extra information in the signal and produce a limited-resolution color display. The higher-resolution black-and-white and lower-resolution color images combine in the brain to produce a seemingly high-resolution color image. The NTSC standard represented a significant technical achievement. The first color broadcast (the first episode of the live program The Marriage ) occurred on 8 July 1954. However, during
14694-472: The facsimile machine between 1843 and 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. Willoughby Smith discovered the photoconductivity of the element selenium in 1873. As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884 in Berlin . This was a spinning disk with a spiral pattern of holes, so each hole scanned
14852-634: The final 4 1 ⁄ 2 years of Search for Tomorrow (1982–1986) after that series was initially cancelled by CBS, although many NBC affiliates did not clear the show during its tenure on the network. NBC has also aired numerous short-lived soap operas, including Generations (1989–1991), Sunset Beach (1997–1999), and the two Another World spin-offs, Somerset (1970–1976) and Texas (1980–1982). Notable daytime game shows that once aired on NBC include The Price Is Right (1956–1963), Concentration (1958–1973; and 1987–1991 as Classic Concentration ), The Match Game (1962–1969), Let's Make
15010-440: The first outdoor remote broadcast of The Derby . In 1932, he demonstrated ultra-short wave television. Baird's mechanical system reached a peak of 240 lines of resolution on BBC telecasts 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. A U.S. inventor, Charles Francis Jenkins , also pioneered
15168-407: The first stations to offer streams of their programming on NBC's website and mobile app, and new affiliation agreements have made a majority of the network's affiliates available through the network's website and app based on a viewer's location. The network's NFL game telecasts were not permitted to be streamed on the service for several years until a change to the league's mobile rights agreement in
15326-431: The following ten years, most network broadcasts and nearly all local programming continued to be black-and-white. It was not until the mid-1960s that color sets started selling in large numbers, due in part to the color transition of 1965, in which it was announced that over half of all network prime-time programming would be broadcast in color that fall. The first all-color prime-time season came just one year later. In 1972,
15484-417: The iconoscope (or Emitron) produced an electronic signal and concluded that its real efficiency was only about 5% of the theoretical maximum. They solved this problem by developing and patenting in 1934 two new camera tubes dubbed super-Emitron and CPS Emitron . The super-Emitron was between ten and fifteen times more sensitive than the original Emitron and iconoscope tubes, and, in some cases, this ratio
15642-637: The industrial standard for public broadcasting in Europe from 1936 until 1960, when it was replaced by the vidicon and plumbicon tubes. Indeed, it represented the European tradition in electronic tubes competing against the American tradition represented by the image orthicon. The German company Heimann produced the Superikonoskop for the 1936 Berlin Olympic Games, later Heimann also produced and commercialized it from 1940 to 1955; finally
15800-437: The invention of the first working transistor at Bell Labs , Sony founder Masaru Ibuka predicted in 1952 that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets. The first fully transistorized, portable solid-state television set was the 8-inch Sony TV8-301 , developed in 1959 and released in 1960. This began the transformation of television viewership from
15958-401: The last holdout among daytime network programs converted to color, resulting in the first completely all-color network season. Early color sets were either floor-standing console models or tabletop versions nearly as bulky and heavy, so in practice they remained firmly anchored in one place. GE 's relatively compact and lightweight Porta-Color set was introduced in the spring of 1966. It used
16116-464: The last of these had converted to color. By the early 1980s, B&W sets had been pushed into niche markets, notably low-power uses, small portable sets, or for use as video monitor screens in lower-cost consumer equipment. By the late 1980s, even these last holdout niche B&W environments had inevitably shifted to color sets. Digital television (DTV) is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to
16274-414: The latter part of the first season of historical action drama Spartacus: Blood and Sand . Knauf wrote two episodes for the first season. Knauf co-wrote with Andrea Berloff and Caleb Pinkett the script for a mystery thriller, The Legend of Cain , but it has not been produced. Knauf was the writer and showrunner of the short-lived NBC series Dracula , before joining the staff of The Blacklist with
16432-486: The mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The availability of various types of archival storage media such as Betamax and VHS tapes, LaserDiscs , high-capacity hard disk drives , CDs , DVDs , flash drives , high-definition HD DVDs and Blu-ray Discs , and cloud digital video recorders has enabled viewers to watch pre-recorded material—such as movies—at home on their own time schedule. For many reasons, especially
16590-451: The mid-90s, he started to think that his screenplay might work as a television piece. He took the first act and reworked it as a television pilot , but shelved the script again when he could not get the project produced. Knauf went on to write the 1994 HBO-produced television movie Blind Justice , and, during a low-point in his screenwriting career, created his own website, posting his resume and Carnivàle 's first act online. He created

NBC began airing a same-day rebroadcast of the parade telecast in 2009 (replacing its annual Thanksgiving afternoon airing of Miracle on 34th Street ). In 2007, NBC acquired
18644-456: The phosphors deposited on their outside faces instead of Baird's 3D patterning on a flat surface. The Penetron used three layers of phosphor on top of each other and increased the power of the beam to reach the upper layers when drawing those colors. The Chromatron used a set of focusing wires to select the colored phosphors arranged in vertical stripes on the tube. One of the great technical challenges of introducing color broadcast television
18802-546: The possibility of a digital television signal. This breakthrough was of such significance that the FCC was persuaded to delay its decision on an ATV standard until a digitally-based standard could be developed. NBC The National Broadcasting Company ( NBC ) is an American commercial broadcast television and radio network serving as the flagship property of the NBC Entertainment division of NBCUniversal ,
18960-507: The public at this time, viewing of the color field tests was restricted to RCA and CBS engineers and the invited press. The War Production Board halted the manufacture of television and radio equipment for civilian use from 22 April 1942 to 20 August 1945, limiting any opportunity to introduce color television to the general public. As early as 1940, Baird had started work on a fully electronic system he called Telechrome . Early Telechrome devices used two electron guns aimed at either side of
19118-512: The receiver, a type of Kerr cell modulated the light, and a series of differently angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image was transmitted "several times" each second. In 1911, Boris Rosing and his student Vladimir Zworykin created
19276-415: The reproducer) marked the start of the end for mechanical systems as the dominant form of television. Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the 1930s. The last mechanical telecasts ended in 1939 at stations run by a lot of public universities in the United States. In 1897, English physicist J. J. Thomson
19434-564: The resolution of the color information to conserve bandwidth. As black-and-white televisions could receive the same transmission and display it in black-and-white, the color system adopted is [backwards] "compatible." ("Compatible Color," featured in RCA advertisements of the period, is mentioned in the song " America ," of West Side Story , 1957.) The brightness image remained compatible with existing black-and-white television sets at slightly reduced resolution. In contrast, color televisions could decode
19592-558: The results of some "not very successful experiments" he had conducted with G. M. Minchin and J. C. M. Stanton. They had attempted to generate an electrical signal by projecting an image onto a selenium-coated metal plate that was simultaneously scanned by a cathode ray beam. These experiments were conducted before March 1914, when Minchin died, but they were later repeated by two different teams in 1937, by H. Miller and J. W. Strange from EMI , and by H. Iams and A. Rose from RCA . Both teams successfully transmitted "very faint" images with

He worked as a writer for the Christian Slater drama My Own Worst Enemy in 2008. From 2006 to 2008, he and his son Charles Knauf wrote issues #7–18 & #21–28 of Iron Man Vol.4 (later retitled Iron Man: Director of S.H.I.E.L.D. ) for Marvel Comics ,. In 2008 they wrote
20224-449: The signal to individual television receivers. Alternatively, television signals are distributed by coaxial cable or optical fiber , satellite systems, and, since the 2000s, via the Internet. Until the early 2000s, these were transmitted as analog signals, but a transition to digital television was expected to be completed worldwide by the late 2010s. A standard television set consists of multiple internal electronic circuits , including
20382-595: 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, WRGB , then W2XB, was started as the world's first television station. It broadcast from the General Electric facility in Schenectady, NY . It
20540-647: The spectrum of colors at the transmitting end and could not have worked as he described it. Another inventor, Hovannes Adamian , also experimented with color television as early as 1907. The first color television project is claimed by him, and was patented in Germany on 31 March 1908, patent No. 197183, then in Britain, on 1 April 1908, patent No. 7219, in France (patent No. 390326) and in Russia in 1910 (patent No. 17912). Scottish inventor John Logie Baird demonstrated
20698-546: The system was improved further by eliminating a motor generator so that his television system had no mechanical parts. That year, Farnsworth transmitted the first live human images with his system, including a three and a half-inch image of his wife Elma ("Pem") with her eyes closed (possibly due to the bright lighting required). Meanwhile, Vladimir Zworykin also experimented with the cathode-ray tube to create and show images. While working for Westinghouse Electric in 1923, he began to develop an electronic camera tube. However, in
20856-849: The television and radio networks were similar to the logo of its then-parent company, RCA. Logos used later in NBC's existence incorporated stylized peacock designs, including the current version that has been in use since 1986. NBC network programs can be received throughout most of Canada on cable, satellite and IPTV providers through certain U.S.-based affiliates of the network (such as WBTS-CD in Boston, KING-TV in Seattle, KBJR-TV in Duluth, Minnesota , WGRZ in Buffalo, New York and WHEC-TV in Rochester, New York ). Some programs carried on these stations are subject to simultaneous substitutions ,

He published an article on "Motion Pictures by Wireless" in 1913, transmitted moving silhouette images for witnesses in December 1923, and on 13 June 1925, publicly demonstrated synchronized transmission of silhouette pictures. In 1925, Jenkins used the Nipkow disk and transmitted the silhouette image of a toy windmill in motion over a distance of 5 miles (8 km), from a naval radio station in Maryland to his laboratory in Washington, D.C., using
21172-546: The term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the first International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris. The anglicized version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires ". It
21330-577: The tube throughout each scanning cycle. The device was first described in a patent application he filed in Hungary in March 1926 for a television system he called "Radioskop". After further refinements included in a 1928 patent application, Tihanyi's patent was declared void in Great Britain in 1930, so he applied for patents in the United States. Although his breakthrough would be incorporated into
21488-545: The unpredictable length of sporting events, NBC will occasionally pre-empt scheduled programs (more common with the weekend editions of NBC Nightly News , and local and syndicated programs carried by its owned-and-operated stations and affiliates). NBC has also held the American broadcasting rights to the Summer Olympic Games since the 1988 games and the rights to the Winter Olympic Games since
21646-522: The use of a CRT as a display device. The Braun tube became the foundation of 20th century television. In 1906 the Germans Max Dieckmann and Gustav Glage produced raster images for the first time in a CRT. In 1907, Russian scientist Boris Rosing used a CRT in the receiving end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen. In 1908, Alan Archibald Campbell-Swinton ,
21804-494: The widespread adoption of television. On 7 September 1927, U.S. inventor Philo Farnsworth 's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. By 3 September 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press. This is widely regarded as the first electronic television demonstration. In 1929,
21962-430: The work of Nipkow and others. However, it was not until 1907 that developments in amplification tube technology by Lee de Forest and Arthur Korn , among others, made the design practical. The first demonstration of the live transmission of images was by Georges Rignoux and A. Fournier in Paris in 1909. A matrix of 64 selenium cells, individually wired to a mechanical commutator , served as an electronic retina . In
22120-457: The world's first color transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color, and three light sources at the receiving end, with a commutator to alternate their illumination. Baird also made the world's first color broadcast on 4 February 1938, sending a mechanically scanned 120-line image from Baird's Crystal Palace studios to
22278-549: The world's first public demonstration of an all-electronic television system, using a live camera, at the Franklin Institute of Philadelphia on 25 August 1934 and for ten days afterward. Mexican inventor Guillermo González Camarena also played an important role in early television. His experiments with television (known as telectroescopía at first) began in 1931 and led to a patent for the "trichromatic field sequential system" color television in 1940. In Britain,
22436-408: Was "...formed in English or borrowed from French télévision ." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904)." The abbreviation TV is from 1948. The use of the term to mean "a television set " dates from 1941. The use of the term to mean "television as
22594-459: Was able, in his three well-known experiments, to deflect cathode rays, a fundamental function of the modern cathode-ray tube (CRT). The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the "Braun" tube. It was a cold-cathode diode , a modification of the Crookes tube , with a phosphor -coated screen. Braun was the first to conceive
22752-402: Was announced that NBC would launch a new Saturday morning preschool block programmed by Sprout (originally jointly owned by NBCUniversal, PBS , Sesame Workshop and Apax Partners , with the former acquiring the other's interests later that year). The block, NBC Kids , premiered on July 7, 2012, replacing the "Qubo on NBC" block. On February 24, 2016, it was announced that NBC would launch
22910-518: Was considerably greater. It was used for outside broadcasting by the BBC, for the first time, on Armistice Day 1937, when the general public could watch on a television set as the King laid a wreath at the Cenotaph. This was the first time that anyone had broadcast a live street scene from cameras installed on the roof of neighboring buildings because neither Farnsworth nor RCA would do the same until
23068-654: Was designed in the Soviet Union in 1944 and became a national standard in 1946. The first broadcast in 625-line standard occurred in Moscow in 1948. The concept of 625 lines per frame was subsequently implemented in the European CCIR standard. In 1936, Kálmán Tihanyi described the principle of plasma display , the first flat-panel display system. Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes . Following
23226-675: Was hosted for most of its run by Ahmad Rashad , was also a part of the TNBC lineup during the NBA season until 2002 (when the program moved to ABC as a result of that network taking the NBA rights from NBC). In 2002, NBC entered into an agreement with Discovery Communications to carry educational children's programs from the Discovery Kids cable channel. Debuting that September, the Discovery Kids on NBC block originally consisted exclusively of live-action series, including reality series Trading Spaces: Boys vs. Girls (a kid-themed version of
23384-411: Was more reliable and visibly superior. This was the world's first regular "high-definition" television service. The original U.S. iconoscope was noisy, had a high ratio of interference to signal, and ultimately gave disappointing results, especially compared to the high-definition mechanical scanning systems that became available. The EMI team, under the supervision of Isaac Shoenberg , analyzed how
23542-408: Was not until the 1990s that digital television became possible. Digital television was previously not practically possible due to the impractically high bandwidth requirements of uncompressed digital video , requiring around 200 Mbit/s for a standard-definition television (SDTV) signal, and over 1 Gbit/s for high-definition television (HDTV). A digital television service
23700-410: Was one by Maurice Le Blanc in 1880 for a color system, including the first mentions in television literature of line and frame scanning. Polish inventor Jan Szczepanik patented a color television system in 1897, using a selenium photoelectric cell at the transmitter and an electromagnet controlling an oscillating mirror and a moving prism at the receiver. But his system contained no means of analyzing
23858-679: Was one of the era's first breakthrough television shows. From the mid-1960s until 1992, the bulk of NBC's children's programming was composed of mainly animated programming including classic Looney Tunes and Woody Woodpecker shorts; reruns of prime time animated sitcoms such as The Flintstones and The Jetsons ; foreign acquisitions like Astro Boy and Kimba the White Lion ; animated adaptions of Punky Brewster , ALF and Star Trek as well as animated vehicles for Gary Coleman and Mr. T ; live-action programs like The Banana Splits , The Bugaloos and H.R. Pufnstuf ; and
24016-855: Was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1,200 rpm and a similar disc spinning in synchronization in front of the cathode-ray tube inside the receiver set. The system was first demonstrated to the Federal Communications Commission (FCC) on 29 August 1940 and shown to the press on 4 September. CBS began experimental color field tests using film as early as 28 August 1940 and live cameras by 12 November. NBC (owned by RCA) made its first field test of color television on 20 February 1941. CBS began daily color field tests on 1 June 1941. These color systems were not compatible with existing black-and-white television sets , and, as no color television sets were available to
24174-524: Was popularly known as " WGY Television." Meanwhile, in the Soviet Union , Leon 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. As part of his thesis, on 7 May 1926, he electrically transmitted and then projected near-simultaneous moving images on a 5-square-foot (0.46 m ) screen. By 1927 Theremin had achieved an image of 100 lines,
24332-517: Was proposed in 1986 by Nippon Telegraph and Telephone (NTT) and the Ministry of Posts and Telecommunication (MPT) in Japan, where there were plans to develop an "Integrated Network System" service. However, it was not possible to implement such a digital television service practically until the adoption of DCT video compression technology made it possible in the early 1990s. In the mid-1980s, as Japanese consumer electronics firms forged ahead with
24490-515: Was the desire to conserve bandwidth , potentially three times that of the existing black-and-white standards, and not use an excessive amount of radio spectrum . In the United States, after considerable research, the National Television Systems Committee approved an all-electronic system developed by RCA , which encoded the color information separately from the brightness information and significantly reduced
24648-580: Was the short-lived Caesars Challenge , which ended in January 1994. Notable past daytime talk shows that have aired on NBC have included Home (1954–1957), The Ernie Kovacs Show (1955–1956), The Merv Griffin Show (1962–1963), Leeza (1994–1999) and Later Today (1999–2000). Children's programming has played a part in NBC's programming since its initial roots in television. NBC's first major children's series, Howdy Doody , debuted in 1947 and
24806-500: Was unable or unwilling to introduce evidence of a working model of his tube that was based on his 1923 patent application. In September 1939, after losing an appeal in the courts and being determined to go forward with the commercial manufacturing of television equipment, RCA agreed to pay Farnsworth US$ 1 million over ten years, in addition to license payments, to use his patents. In 1933, RCA introduced an improved camera tube that relied on Tihanyi's charge storage principle. Called
24964-419: Was varied in proportion to the brightness of each spot on the image. As each hole in the disk passed by, one scan line of the image was reproduced. Baird's disk had 30 holes, producing an image with only 30 scan lines, just enough to recognize a human face. In 1927, Baird transmitted a signal over 438 miles (705 km) of telephone line between London and Glasgow . Baird's original 'televisor' now resides in
