In , he made the first outdoor remote broadcast, of The Derby. Baird's mechanical system reached a peak of lines of resolution on BBC television broadcasts in , though the mechanical system did not scan the televised scene directly.

Instead a An American inventor, Charles Francis Jenkins , also pioneered the television. He published an article on "Motion Pictures by Wireless" in , but it was not until December that he transmitted moving silhouette images for witnesses; and it was on 13 June , that he publicly demonstrated synchronized transmission of silhouette pictures.

Patent No. Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on 7 April Their reflected-light television system included both small and large viewing screens.

The small receiver had a 2-inch-wide by 2. Both sets were capable of reproducing reasonably accurate, monochromatic, moving images.

Along with the pictures, the sets received synchronized sound. The system transmitted images over two paths: first, a copper wire link from Washington to New York City, then 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 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 Television historian Albert Abramson underscored 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 , WRGB , then W2XB, was started as the world's first television station.

It broadcast from the General Electric facility in Schenectady, NY. It was popularly known as " WGY Television".

As part of his thesis, on 7 May , he electrically transmitted, and then projected, near-simultaneous moving images on a 5-square-foot 0. By , Theremin had achieved an image of lines, a resolution that was not surpassed until May by RCA, with lines.

On 25 December , Kenjiro Takayanagi demonstrated a television system with a 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 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 or so.

Nevertheless, the image quality of line transmissions steadily improved with technical advances, and by the UK broadcasts using the Baird system were remarkably clear.

Two of these were the line system that Compagnie des Compteurs CDC installed in Paris in , and the line system that Peck Television Corp.

Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the s.

The last mechanical television broadcasts ended in at stations run by a handful of public universities in the United States.

In , English physicist J. Thomson was able, in his three famous 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 and is also known as the "Braun" tube.

In the Germans Max Dieckmann and Gustav Glage produced raster images for the first time in a CRT. He managed to display simple geometric shapes onto the screen.

In Alan Archibald Campbell-Swinton , 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, [34] [35] He expanded on his vision in a speech given in London in and reported in The Times [36] and the Journal of the Röntgen Society.

Minchin and J. 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.

Miller and J. Strange from EMI , [42] and by H. Iams and A. Rose from RCA. Although others had experimented with using a cathode ray tube as a receiver, the concept of using one as a transmitter was novel.

Johnson who gave his name to the term Johnson noise and Harry Weiner Weinhart of Western Electric , and became a commercial product in The device was first described in a patent application he filed in Hungary in March for a television system he dubbed "Radioskop".

Although his breakthrough would be incorporated into the design of RCA 's " iconoscope " in , the U. The patent for his receiving tube had been granted the previous October.

Both patents had been purchased by RCA prior to their approval. Takayanagi did not apply for a patent.

In the s, Allen B. DuMont made the first CRTs to last 1, hours of use, which was one of the factors that led to the widespread adoption of television.

On 7 September , American inventor Philo Farnsworth 's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at Green Street in San Francisco.

This is widely regarded as the first electronic television demonstration. Meanwhile, Vladimir Zworykin was also experimenting with the cathode ray tube to create and show images.

While working for Westinghouse Electric in , he began to develop an electronic camera tube. But in a demonstration, the image was dim, had low contrast, and poor definition, and was stationary.

But RCA, which acquired the Westinghouse patent, asserted that the patent for Farnsworth's image dissector was written so broadly that it would exclude any other electronic imaging device.

Thus RCA, on the basis of Zworykin's patent application, filed a patent interference suit against Farnsworth. The U. Patent Office examiner disagreed in a decision, finding priority of invention for Farnsworth against Zworykin.

Farnsworth claimed that Zworykin's system would be unable to produce an electrical image of the type to challenge his patent. Zworykin received a patent in for a color transmission version of his patent application; [61] he also divided his original application in In , RCA introduced an improved camera tube that relied on Tihanyi's charge storage principle.

Unfortunately, a problem with the multipactor was that it wore out at an unsatisfactory rate. At the Berlin Radio Show in August , Manfred von Ardenne gave a public demonstration of a television system using a CRT for both transmission and reception.

However, Ardenne had not developed a camera tube, using the CRT instead as a flying-spot scanner to scan slides and film. On 2 November , a line broadcasting service employing the Emitron began at studios in Alexandra Palace , and transmitted from a specially built mast atop one of the Victorian building's towers.

It alternated for a short time with Baird's mechanical system in adjoining studios, but was more reliable and visibly superior. This was the world's first regular "high-definition" television service.

The original American iconoscope was noisy, had a high ratio of interference to signal, and ultimately gave disappointing results, especially when compared to the high definition mechanical scanning systems then becoming available.

On the other hand, in , Zworykin shared some patent rights with the German licensee company Telefunken. This tube is essentially identical to the super-Emitron.

Indeed, it was the representative of the European tradition in electronic tubes competing against the American tradition represented by the image orthicon.

American television broadcasting, at the time, consisted of a variety of markets in a wide range of sizes, each competing for programming and dominance with separate technology, until deals were made and standards agreed upon in The world's first line television standard was designed in the Soviet Union in and became a national standard in Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes.

Following the invention of the first working transistor at Bell Labs , Sony founder Masaru Ibuka predicted in that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets.

The basic idea of using three monochrome images to produce a color image had been experimented with almost as soon as black-and-white televisions had first been built.

Although he gave no practical details, among the earliest published proposals for television was one by Maurice Le Blanc, in , for a color system, including the first mentions in television literature of line and frame scanning.

But his system contained no means of analyzing the spectrum of colors at the transmitting end, and could not have worked as he described it.

The first color television project is claimed by him, [] and was patented in Germany on 31 March , patent No. Scottish inventor John Logie Baird demonstrated the world's first color transmission on 3 July , 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.

The first practical hybrid system was again pioneered by John Logie Baird. In he publicly demonstrated 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.

In , Hungarian engineer Peter Carl Goldmark introduced an electro-mechanical system while at CBS , which contained an Iconoscope sensor.

The CBS field-sequential color system was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1, rpm, and a similar disc spinning in synchronization in front of the cathode ray tube inside the receiver set.

CBS began experimental color field tests using film as early as 28 August , and live cameras by 12 November.

CBS began daily color field tests on 1 June The War Production Board halted the manufacture of television and radio equipment for civilian use from 22 April to 20 August , limiting any opportunity to introduce color television to the general public.

As early as , Baird had started work on a fully electronic system he called Telechrome. Early Telechrome devices used two electron guns aimed at either side of a phosphor plate.

The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-color image could be obtained.

He also demonstrated the same system using monochrome signals to produce a 3D image called " stereoscopic " at the time.

A demonstration on 16 August was the first example of a practical color television system. Work on the Telechrome continued and plans were made to introduce a three-gun version for full color.

However, Baird's untimely death in ended development of the Telechrome system. The Geer tube was similar to Baird's concept, but used small pyramids with 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 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 greatly reduced the resolution of the color information in order to conserve bandwidth.

As black-and-white TVs could receive the same transmission and display it in black-and-white, the color system adopted is [backwards] "compatible".

The brightness image remained compatible with existing black-and-white television sets at slightly reduced resolution, while color televisions could decode 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 major technical achievement. The first color broadcast the first episode of the live program The Marriage occurred on 8 July , but during the following ten years most network broadcasts, and nearly all local programming, continued to be in black-and-white.

It was not until the mids that color sets started selling in large numbers, due in part to the color transition of 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 , 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 It used a transistor -based UHF tuner. The MOSFET metal-oxide-semiconductor field-effect transistor, or MOS transistor was invented by Mohamed M.

Atalla and Dawon Kahng at Bell Labs in , [] and presented in Austin, J. Dean, D. Griswold and O. Hart in described the use of the MOSFET in television circuits, including RF amplifier , low-level video, chroma and AGC circuits.

In , sales of color sets finally surpassed sales of black-and-white sets. Color broadcasting in Europe was not standardized on the PAL format until the s, and broadcasts did not start until By this point many of the technical problems in the early sets had been worked out, and the spread of color sets in Europe was fairly rapid.

By the mids, the only stations broadcasting in black-and-white were a few high-numbered UHF stations in small markets, and a handful of low-power repeater stations in even smaller markets such as vacation spots.

By the late s even these areas switched to color sets. Digital television DTV is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to the totally analog and channel separated signals used by analog television.

Due to data compression , digital TV can support more than one program in the same channel bandwidth. It was not until the s that digital TV became feasible.

Digital TV became practically feasible in the early s due to a major technological development, discrete cosine transform DCT video compression.

A digital TV service was proposed in 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 practically implement such a digital TV service until the adoption of DCT video compression technology made it possible in the early s.

In the mids, as Japanese consumer electronics firms forged ahead with 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.

Until June , the Japanese MUSE standard, based on an analog system, was the front-runner among the more than 23 different technical concepts under consideration.

Then, an American company, General Instrument, demonstrated the feasibility 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.

In March , when it became clear that a digital standard was feasible, the FCC made a number of critical decisions.

First, the Commission declared that the new ATV standard must be more than an enhanced analog signal, but be able to provide a genuine HDTV signal with at least twice the resolution of existing television images.

Although incompatible with the existing NTSC standard, the new DTV standard would be able to incorporate many improvements. The final standards adopted by the FCC did not require a single standard for scanning formats, aspect ratios , or lines of resolution.

This compromise resulted from a dispute between the consumer electronics industry joined by some broadcasters and the computer industry joined by the film industry and some public interest groups over which of the two scanning processes—interlaced or progressive—would be best suited for the newer digital HDTV compatible display devices.

In fact, interlaced scanning can be looked at as the first video compression model as it was partly designed in the s to double the image resolution to exceed the limitations of the television broadcast bandwidth.

Another reason for its adoption was to limit the flickering on early CRT screens whose phosphor coated screens could only retain the image from the electron scanning gun for a relatively short duration.

Progressive scanning , the format that the computer industry had long adopted for computer display monitors, scans every line in sequence, from top to bottom.

The computer industry argued that progressive scanning is superior because it does not "flicker" on the new standard of display devices in the manner of interlaced scanning.

It also argued that progressive scanning enables easier connections with the Internet, and is more cheaply converted to interlaced formats than vice versa.

The film industry also supported progressive scanning because it offered a more efficient means of converting filmed programming into digital formats.

For their part, the consumer electronics industry and broadcasters argued that interlaced scanning was the only technology that could transmit the highest quality pictures then and currently feasible, i.

Broadcasters also favored interlaced scanning because their vast archive of interlaced programming is not readily compatible with a progressive format.

William F. Schreiber , who was director of the Advanced Television Research Program at the Massachusetts Institute of Technology from until his retirement in , thought that the continued advocacy of interlaced equipment originated from consumer electronics companies that were trying to get back the substantial investments they made in the interlaced technology.

Digital television transition started in late s. All governments across the world set the deadline for analog shutdown by s.

Initially the adoption rate was low, as the first digital tuner-equipped TVs were costly. But soon, as the price of digital-capable TVs dropped, more and more households were converting to digital televisions.

The transition is expected to be completed worldwide by mid to late s. The advent of digital television allowed innovations like smart TVs.

A smart television, sometimes referred to as connected TV or hybrid TV, is a television set or set-top box with integrated Internet and Web 2.

Besides the traditional functions of television sets and set-top boxes provided through traditional Broadcasting media, these devices can also provide Internet TV, online interactive media , over-the-top content , as well as on-demand streaming media , and home networking access.

These TVs come pre-loaded with an operating system. Smart TV should not to be confused with Internet TV , Internet Protocol television IPTV or with Web TV.

Internet television refers to the receiving of television content over the Internet instead of by traditional systems—terrestrial, cable and satellite although internet itself is received by these methods.

IPTV is one of the emerging Internet television technology standards for use by television broadcasters.

Web television WebTV is a term used for programs created by a wide variety of companies and individuals for broadcast on Internet TV.

A first patent was filed in [] and extended the following year [] for an "intelligent" television system, linked with data processing systems, by means of a digital or analog network.

Apart from being linked to data networks, one key point is its ability to automatically download necessary software routines, according to a user's demand, and process their needs.

Major TV manufacturers have announced production of smart TVs only, for middle-end and high-end TVs in Most modern 3D television sets use an active shutter 3D system or a polarized 3D system , and some are autostereoscopic without the need of glasses.

Stereoscopic 3D television was demonstrated for the first time on 10 August , by John Logie Baird in his company's premises at Long Acre, London.

The first 3D TV was produced in The advent of digital television in the s greatly improved 3D TVs. Although 3D TV sets are quite popular for watching 3D home media such as on Blu-ray discs, 3D programming has largely failed to make inroads with the public.

Many 3D television channels which started in the early s were shut down by the mids. According to DisplaySearch 3D televisions shipments totaled Programming is broadcast by television stations, sometimes called "channels", as stations are licensed by their governments to broadcast only over assigned channels in the television band.

At first, terrestrial broadcasting was the only way television could be widely distributed, and because bandwidth was limited, i. In the U. By contrast, the United Kingdom chose a different route, imposing a television license fee on owners of television reception equipment to fund the British Broadcasting Corporation BBC , which had public service as part of its Royal Charter.

WRGB claims to be the world's oldest television station, tracing its roots to an experimental station founded on 13 January , broadcasting from the General Electric factory in Schenectady, NY , under the call letters W2XB.

Later in , General Electric started a second facility, this one in New York City, which had the call letters W2XBS and which today is known as WNBC.

The two stations were experimental in nature and had no regular programming, as receivers were operated by engineers within the company. The image of a Felix the Cat doll rotating on a turntable was broadcast for 2 hours every day for several years as new technology was being tested by the engineers.

On 2 November , the BBC began transmitting the world's first public regular high-definition service from the Victorian Alexandra Palace in north London.

All other countries around the world are also in the process of either shutting down analog terrestrial television or switching over to digital terrestrial television.

Cable television is a system of broadcasting television programming to paying subscribers via radio frequency RF signals transmitted through coaxial cables or light pulses through fiber-optic cables.

This contrasts with traditional terrestrial television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television.

In the s, FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.

The abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, from cable television's origins in in areas where over-the-air reception was limited by distance from transmitters or mountainous terrain, large "community antennas" were constructed, and cable was run from them to individual homes.

Earlier cable television was analog, but since the s, all cable operators have switched to, or are in the process of switching to, digital cable television.

Satellite television is a system of supplying television programming using broadcast signals relayed from communication satellites. The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter LNB.

A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes , or a built-in television tuner.

Satellite television provides a wide range of channels and services, especially to geographic areas without terrestrial television or cable television.

The most common method of reception is direct-broadcast satellite television DBSTV , also known as "direct to home" DTH. These systems received analog signals transmitted in the C-band spectrum from FSS type satellites, and required the use of large dishes.

Consequently, these systems were nicknamed "big dish" systems, and were more expensive and less popular. The direct-broadcast satellite television signals were earlier analog signals and later digital signals, both of which require a compatible receiver.

Digital signals may include high-definition television HDTV. Some transmissions and channels are free-to-air or free-to-view , while many other channels are pay television requiring a subscription.

Clarke proposed a worldwide communications system which would function by means of three satellites equally spaced apart in earth orbit. The first satellite television signals from Europe to North America were relayed via the Telstar satellite over the Atlantic ocean on 23 July The world's first commercial communications satellite, called Intelsat I and nicknamed "Early Bird", was launched into geosynchronous orbit on 6 April The transmissions were focused on the Indian subcontinent but experimenters were able to receive the signal in Western Europe using home constructed equipment that drew on UHF television design techniques already in use.

The first in a series of Soviet geostationary satellites to carry Direct-To-Home television, Ekran 1, was launched on 26 October Internet television Internet TV or online television is the digital distribution of television content via the Internet as opposed to traditional systems like terrestrial, cable, and satellite, although the Internet itself is received by terrestrial, cable, or satellite methods.

Internet television is a general term that covers the delivery of television shows, and other video content, over the Internet by video streaming technology, typically by major traditional television broadcasters.

Internet television should not be confused with Smart TV , IPTV or with Web TV. Smart television refers to the TV set which has a built-in operating system.

Internet Protocol television IPTV is one of the emerging Internet television technology standards for use by television broadcasters.

Web television is a term used for programs created by a wide variety of companies and individuals for broadcast on Internet TV.

A television set, also called a television receiver, television, TV set, TV, or "telly", is a device that combines a tuner, display, an amplifier, and speakers for the purpose of viewing television and hearing its audio components.

Introduced in the late s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tubes.

The addition of color to broadcast television after further increased the popularity of television sets and an outdoor antenna became a common feature of suburban homes.

The ubiquitous television set became the display device for recorded media in the s, such as Betamax and VHS , which enabled viewers to record TV shows and watch prerecorded movies.

In the subsequent decades, TVs were used to watch DVDs and Blu-ray Discs of movies and other content. Major TV manufacturers announced the discontinuation of CRT, DLP, plasma and fluorescent-backlit LCDs by the mids.

Televisions since s mostly use LEDs. The earliest systems employed a spinning disk to create and reproduce images. The cathode ray tube CRT is a vacuum tube containing one or more electron guns a source of electrons or electron emitter and a fluorescent screen used to view images.

The images may represent electrical waveforms oscilloscope , pictures television, computer monitor , radar targets or others.

The CRT uses an evacuated glass envelope which is large, deep i. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.

In television sets and computer monitors , the entire front area of the tube is scanned repetitively and systematically in a fixed pattern called a raster.

An image is produced by controlling the intensity of each of the three electron beams , one for each additive primary color red, green, and blue with a video signal as a reference.

Digital Light Processing DLP is a type of video projector technology that uses a digital micromirror device.

Some DLPs have a TV tuner, which makes them a type of TV display. It was originally developed in by Dr. Larry Hornbeck of Texas Instruments.

While the DLP imaging device was invented by Texas Instruments, the first DLP based projector was introduced by Digital Projection Ltd in Digital Projection and Texas Instruments were both awarded Emmy Awards in for invention of the DLP projector technology.

DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses.

DLP technology is used in DLP front projectors standalone projection units for classrooms and business primarily , but also in private homes; in these cases, the image is projected onto a projection screen.

DLP is also used in DLP rear projection television sets and digital signs. They are called " plasma " displays because the technology utilizes small cells containing electrically charged ionized gases , or what are in essence chambers more commonly known as fluorescent lamps.

Liquid-crystal-display televisions LCD TV are television sets that use LCD display technology to produce images. LCD televisions are much thinner and lighter than cathode ray tube CRTs of similar display size, and are available in much larger sizes e.

When manufacturing costs fell, this combination of features made LCDs practical for television receivers.

LCDs come in two types: those using cold cathode fluorescent lamps, simply called LCDs and those using LED as backlight called as LEDs.

In , LCD televisions surpassed sales of CRT-based televisions worldwide for the first time, and their sales figures relative to other technologies accelerated.

LCD TVs have quickly displaced the only major competitors in the large-screen market, the Plasma display panel and rear-projection television.

Other technologies address these weaknesses, including OLEDs , FED and SED , but as of [update] none of these have entered widespread production.

An OLED organic light-emitting diode is a light-emitting diode LED in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current.

This layer of organic semiconductor is situated between two electrodes. Generally, at least one of these electrodes is transparent.

OLEDs are used to create digital displays in devices such as television screens. It is also used for computer monitors, portable systems such as mobile phones , handheld game consoles and PDAs.

There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell or LEC, which has a slightly different mode of operation.

OLED displays can use either passive-matrix PMOLED or active-matrix AMOLED addressing schemes. Active-matrix OLEDs require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.

An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display LCD.

In low ambient light conditions such as a dark room an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses cold cathode fluorescent lamps or LED backlight.

OLEDs are expected to replace other forms of display in near future. It is used in handheld television. The most common source of LDTV programming is the Internet, where mass distribution of higher-resolution video files could overwhelm computer servers and take too long to download.

For the first years of its existence, YouTube offered only one, low-definition resolution of xp at 30fps or less. Standard-definition television or SDTV refers to two different resolutions: i , with interlaced lines of resolution, derived from the European-developed PAL and SECAM systems; and i based on the American National Television System Committee NTSC system.

SDTV is a television system that uses a resolution that is not considered to be either high-definition television p , i , p , p , 4K UHDTV , and 8K UHD or enhanced-definition television EDTV p.

In North America, digital SDTV is broadcast in the same aspect ratio as NTSC signals with widescreen content being center cut.

Older programs with a aspect ratio are shown in the US as with non-ATSC countries preferring to reduce the horizontal resolution by anamorphically scaling a pillarboxed image.

High-definition television HDTV provides a resolution that is substantially higher than that of standard-definition television.

North American consumers purchase a new television set on average every seven years, and the average household owns 2. Getting TV programming shown to the public can happen in many different ways.

After production, the next step is to market and deliver the product to whichever markets are open to using it. This typically happens on two levels:.

First-run programming is increasing on subscription services outside the US, but few domestically produced programs are syndicated on domestic free-to-air FTA elsewhere.

This practice is increasing, however, generally on digital-only FTA channels or with subscriber-only, first-run material appearing on FTA.

Unlike the US, repeat FTA screenings of an FTA network program usually only occur on that network. Also, affiliates rarely buy or produce non-network programming that is not centered on local programming.

Television genres include a broad range of programming types that entertain, inform, and educate viewers. The most expensive entertainment genres to produce are usually dramas and dramatic miniseries.

However, other genres, such as historical Western genres, may also have high production costs. Popular culture entertainment genres include action-oriented shows such as police, crime, detective dramas, horror, or thriller shows.

As well, there are also other variants of the drama genre, such as medical dramas and daytime soap operas. Science fiction shows can fall into either the drama or action category, depending on whether they emphasize philosophical questions or high adventure.

Comedy is a popular genre which includes situation comedy sitcom and animated shows for the adult demographic such as South Park.

The least expensive forms of entertainment programming genres are game shows, talk shows, variety shows, and reality television.

Game shows feature contestants answering questions and solving puzzles to win prizes. Talk shows contain interviews with film, television, music and sports celebrities and public figures.

Variety shows feature a range of musical performers and other entertainers, such as comedians and magicians, introduced by a host or Master of Ceremonies.

There is some crossover between some talk shows and variety shows because leading talk shows often feature performances by bands, singers, comedians, and other performers in between the interview segments.

Reality TV shows "regular" people i. A variant version of reality shows depicts celebrities doing mundane activities such as going about their everyday life The Osbournes , Snoop Dogg's Father Hood or doing regular jobs The Simple Life.

Fictional television programs that some television scholars and broadcasting advocacy groups argue are " quality television ", include series such as Twin Peaks and The Sopranos.

Kristin Thompson argues that some of these television series exhibit traits also found in art films , such as psychological realism, narrative complexity, and ambiguous plotlines.

Nonfiction television programs that some television scholars and broadcasting advocacy groups argue are "quality television", include a range of serious, noncommercial, programming aimed at a niche audience, such as documentaries and public affairs shows.

Around the globe, broadcast TV is financed by government, advertising, licensing a form of tax , subscription, or any combination of these.

To protect revenues, subscription TV channels are usually encrypted to ensure that only subscribers receive the decryption codes to see the signal.

Unencrypted channels are known as free to air or FTA. In , the global TV market represented 1, TV's broad reach makes it a powerful and attractive medium for advertisers.

Many TV networks and stations sell blocks of broadcast time to advertisers "sponsors" to fund their programming.

Advertising revenue provides a significant portion of the funding for most privately owned television networks. The vast majority of television advertisements today consist of brief advertising spots, ranging in length from a few seconds to several minutes as well as program-length infomercials.

Advertisements of this sort have been used to promote a wide variety of goods, services and ideas since the beginning of television.

The effects of television advertising upon the viewing public and the effects of mass media in general have been the subject of philosophical discourse by such luminaries as Marshall McLuhan.

The viewership of television programming, as measured by companies such as Nielsen Media Research , is often used as a metric for television advertisement placement, and consequently, for the rates charged to advertisers to air within a given network, television program, or time of day called a "daypart".

In many countries, including the United States, television campaign advertisements are considered indispensable for a political campaign.

In other countries, such as France, political advertising on television is heavily restricted, [] while some countries, such as Norway , completely ban political advertisements.

The first official, paid television advertisement was broadcast in the United States on 1 July over New York station WNBT now WNBC before a baseball game between the Brooklyn Dodgers and Philadelphia Phillies.

The Bulova logo, with the phrase "Bulova Watch Time", was shown in the lower right-hand quadrant of the test pattern while the second hand swept around the dial for one minute.

The first TV ad broadcast in Asia was on Nippon Television in Tokyo on 28 August , advertising Seikosha now Seiko , which also displayed a clock with the current time.

Since inception in the US in , [] television commercials have become one of the most effective, persuasive, and popular methods of selling products of many sorts, especially consumer goods.

During the s and into the s, programs were hosted by single advertisers. This, in turn, gave great creative license to the advertisers over the content of the show.

Perhaps due to the quiz show scandals in the s, [] networks shifted to the magazine concept, introducing advertising breaks with multiple advertisers.

US advertising rates are determined primarily by Nielsen ratings. The time of the day and popularity of the channel determine how much a TV commercial can cost.

Conversely, lesser-viewed time slots , such as early mornings and weekday afternoons, are often sold in bulk to producers of infomercials at far lower rates.

In recent years, the paid program or infomercial has become common, usually in lengths of 30 minutes or one hour.

Some drug companies and other businesses have even created "news" items for broadcast, known in the industry as video news releases , paying program directors to use them.

Some TV programs also deliberately place products into their shows as advertisements, a practice started in feature films [] and known as product placement.

For example, a character could be drinking a certain kind of soda, going to a particular chain restaurant , or driving a certain make of car. This is sometimes very subtle, with shows having vehicles provided by manufacturers for low cost in exchange as a product placement.

Sometimes, a specific brand or trade mark , or music from a certain artist or group, is used. This excludes guest appearances by artists who perform on the show.

The TV regulator oversees TV advertising in the United Kingdom. Its restrictions have applied since the early days of commercially funded TV.

Despite this, an early TV mogul, Roy Thomson , likened the broadcasting licence as being a "licence to print money".

Other broadcasters must average no more than nine minutes twelve in the peak. This means that many imported TV shows from the US have unnatural pauses where the UK company does not utilize the narrative breaks intended for more frequent US advertising.

Advertisements must not be inserted in the course of certain specific proscribed types of programs which last less than half an hour in scheduled duration; this list includes any news or current affairs programs, documentaries, and programs for children; additionally, advertisements may not be carried in a program designed and broadcast for reception in schools or in any religious broadcasting service or other devotional program or during a formal Royal ceremony or occasion.

There also must be clear demarcations in time between the programs and the advertisements. The BBC , being strictly non-commercial , is not allowed to show advertisements on television in the UK, although it has many advertising-funded channels abroad.

The majority of its budget comes from television license fees see below and broadcast syndication , the sale of content to other broadcasters.

Broadcast advertising is regulated by the Broadcasting Authority of Ireland. Some TV channels are partly funded from subscriptions ; therefore, the signals are encrypted during broadcast to ensure that only the paying subscribers have access to the decryption codes to watch pay television or specialty channels.

Most subscription services are also funded by advertising. Television services in some countries may be funded by a television licence or a form of taxation, which means that advertising plays a lesser role or no role at all.

For example, some channels may carry no advertising at all and some very little, including:. The BBC carries no television advertising on its UK channels and is funded by an annual television licence paid by premises receiving live TV broadcasts.

Currently, it is estimated that approximately Other than internal promotional material, the Australian Broadcasting Corporation ABC carries no advertising; it is banned under the ABC Act The ABC receives its funding from the Australian government every three years.

The ABC also receives funds from its many ABC shops across Australia. Although funded by the Australian government, the editorial independence of the ABC is ensured through law.

In France, government-funded channels carry advertisements, yet those who own television sets have to pay an annual tax "la redevance audiovisuelle".

The broadcast law that governs NHK's funding stipulates that any television equipped to receive NHK is required to pay.

The fee is standardized, with discounts for office workers and students who commute, as well a general discount for residents of Okinawa prefecture.

Broadcast programming, or TV listings in the United Kingdom, is the practice of organizing television programs in a schedule, with broadcast automation used to regularly change the scheduling of TV programs to build an audience for a new show, retain that audience, or compete with other broadcasters' programs.

Television has played a pivotal role in the socialization of the 20th and 21st centuries. There are many aspects of television that can be addressed, including negative issues such as media violence.

Current research is discovering that individuals suffering from social isolation can employ television to create what is termed a parasocial or faux relationship with characters from their favorite television shows and movies as a way of deflecting feelings of loneliness and social deprivation.

The article "The Good Things about Television" [] argues that television can be a very powerful and effective learning tool for children if used wisely.

Methodist denominations in the conservative holiness movement , such as the Allegheny Wesleyan Methodist Connection and the Evangelical Wesleyan Church , eschew the use of the television.

Children, especially those aged 5 or younger, are at risk of injury from falling televisions. A study in The Journal of Human Resources found that exposure to cable television reduced cognitive ability and high school graduation rates for boys.

This effect was stronger for boys from more educated families. The article suggests a mechanism where light television entertainment crowds out more cognitively stimulating activities.

With high lead content in CRTs and the rapid diffusion of new flat-panel display technologies, some of which LCDs use lamps which contain mercury , there is growing concern about electronic waste from discarded televisions.

Related occupational health concerns exist, as well, for disassemblers removing copper wiring and other materials from CRTs.

Further environmental concerns related to television design and use relate to the devices' increasing electrical energy requirements.
