Silent film
–
A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936, in silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards which contain a written indication of the plot or key dialogue. During silent films, a pianist, theatre organist, or, in large cities, pianists and organists would either play from sheet music or improvise, an orchestra would play from sheet music. The term silent film is therefore a retronym—that is, a term created to distinguish something retroactively, the early films with sound, starting with The Jazz Singer in 1927, were referred to as talkies, sound films, or talking pictures. A September 2013 report by the United States Library of Congress announced that a total of 70% of American silent feature films are believed to be completely lost, the earliest precursors of film began with image projection through the use of a device known as the magic lantern. This utilized a glass lens, a shutter and a persistent light source, such as a powerful lantern and these slides were originally hand-painted, but still photographs were used later on after the technological advent of photography in the nineteenth century. The invention of a practical photography apparatus preceded cinema by only fifty years, the next significant step towards film creation was the development of an understanding of image movement. Simulations of movement date as far back as to 1828 and only four years after Paul Roget discovered the phenomenon he called Persistence of Vision. This experience was further demonstrated through Rogets introduction of the thaumatrope, the first projected primary proto-movie was made by Eadweard Muybridge between 1877 and 1880. Muybridge set up a row of cameras along a racetrack and timed image exposures to capture the many stages of a horses gallop, the oldest surviving film was created by Louis Le Prince in 1888. It was a film of people walking in Oakwood streets garden. Edison also made a business of selling Kinetograph and Kinetoscope equipment, due to Edisons lack of securing an international patent on his film inventions, similar devices were invented around the world. The Lumière brothers, for example, created the Cinématographe in France, the Cinématographe proved to be a more portable and practical device than both of Edisons as it combined a camera, film processor and projector in one unit. In contrast to Edisons peepshow-style kinetoscope, which one person could watch through a viewer. Their first film, Sortie de lusine Lumière de Lyon, shot in 1894, is considered the first true motion picture, the invention of celluloid film, which was strong and flexible, greatly facilitated the making of motion pictures. This film was 35 mm wide and pulled using four sprocket holes and this doomed the cinematograph, which could only use film with just one sprocket hole. From the very beginnings of film production, the art of motion pictures grew into maturity in the silent era. Silent filmmakers pioneered the art form to the extent that virtually every style, the silent era was also pioneering era from a technical point of view

Roger Fry
–
Roger Eliot Fry was an English painter and critic, and a member of the Bloomsbury Group. Establishing his reputation as a scholar of the Old Masters, he became an advocate of more recent developments in French painting and he was described by the art historian Kenneth Clark as incomparably the greatest influence on taste since Ruskin. In so far as taste can be changed by one man, born in London, the son of the judge Edward Fry, he grew up in a wealthy Quaker family in Highgate. Fry was educated at Clifton College and Kings College, Cambridge, at Cambridge, Fry met many freethinking men who would shape the foundation of his interest in the arts. Alongside men like John McTaggart and Goldsworthy Lowes Dickinson, Fry was a part of the elite Conversazione Society, after taking a first in the Natural Science tripos, he went to Paris and then Italy to study art. Eventually he specialised in landscape painting, in 1896, he married the artist Helen Coombe and they subsequently had two children, Pamela and Julian. Helen soon became mentally ill, and in 1910 was committed to a mental institution. Fry took over the care of their children with the help of his sister and that same year, Fry met the artists Vanessa Bell and her husband Clive Bell, and it was through them that he was introduced to the Bloomsbury Group. Vanessas sister, the author Virginia Woolf later wrote in her biography of Fry that He had more knowledge, in 1911, Fry began an affair with Vanessa Bell, who was recovering from a miscarriage. Fry offered her the tenderness and care she felt was lacking from her husband and they remained lifelong close friends, even though Frys heart was broken in 1913 when Vanessa fell in love with Duncan Grant and decided to live permanently with him. After short affairs with artists as Nina Hamnett and Josette Coatmellec. She became his emotional anchor for the rest of his life, Fry died very unexpectedly after a fall at his home in London. His death caused great sorrow among the members of the Bloomsbury Group, Vanessa Bell decorated his casket before his ashes were placed in the vault of Kings College Chapel in Cambridge. Virginia Woolf, Vanessas sister, novelist and a friend of his as well, was entrusted with writing his biography published in 1940. As a painter Fry was experimental, but his best pictures were straightforward naturalistic portraits, in his art he explored his own sensations and gradually his own personal visions and attitudes asserted themselves. His work was considered to give pleasure, communicating the delight of unexpected beauty, Fry did not consider himself a great artist, only a serious artist with some sensibility and taste. He considered Cowdray Park his best painting the best thing, in a way that I have done, in the 1900s, Fry started to teach art history at the Slade School of Fine Art, University College London. In 1903 Fry was involved in the foundation of The Burlington Magazine, Fry wrote for The Burlington from 1903 until his death, he published over two hundred pieces of eclectic subjects – from childrens drawings to bushman art

Wassily Kandinsky
–
Wassily Wassilyevich Kandinsky was a Russian painter and art theorist. He is credited with painting one of the first recognised purely abstract works, born in Moscow, Kandinsky spent his childhood in Odessa, where he graduated at Grekov Odessa Art school. He enrolled at the University of Moscow, studying law and economics, successful in his profession—he was offered a professorship at the University of Dorpat—Kandinsky began painting studies at the age of 30. In 1896 Kandinsky settled in Munich, studying first at Anton Ažbes private school and he returned to Moscow in 1914, after the outbreak of World War I. Kandinsky was unsympathetic to the theories on art in Communist Moscow. There, he taught at the Bauhaus school of art and architecture from 1922 until the Nazis closed it in 1933. He then moved to France, where he lived for the rest of his life, becoming a French citizen in 1939 and he died at Neuilly-sur-Seine in 1944. Kandinskys creation of work followed a long period of development. He called this devotion to beauty, fervor of spirit. Kandinsky was born in Moscow, the son of Lidia Ticheeva and Vasily Silvestrovich Kandinsky, Kandinsky learned from a variety of sources while in Moscow. He studied many fields while in school, including law and economics, later in life, he would recall being fascinated and stimulated by colour as a child. His fascination with colour symbolism and psychology continued as he grew, in 1889, he was part of an ethnographic research group which travelled to the Vologda region north of Moscow. In Looks on the Past, he relates that the houses and churches were decorated with such shimmering colours that upon entering them and this experience, and his study of the regions folk art, was reflected in much of his early work. The artist is the hand plays, touching one key or another. Kandinsky was also the uncle of Russian-French philosopher Alexandre Kojève, in 1896, at the age of 30, Kandinsky gave up a promising career teaching law and economics to enroll in the Munich Academy where his teachers would eventually include Franz von Stuck. He was not immediately granted admission, and began learning art on his own and that same year, before leaving Moscow, he saw an exhibit of paintings by Monet. He was particularly taken with the style of Haystacks, this. Later, he would write about this experience, That it was a haystack the catalogue informed me and this non-recognition was painful to me

Fine art
–
Historically, the five main fine arts were painting, sculpture, architecture, music and poetry, with performing arts including theatre and dance. Today, the fine arts commonly include additional forms, such as film, photography, video production/editing, design, sequential art, conceptual art, and printmaking. However, in some institutes of learning or in museums, fine art, in that sense, there are conceptual differences between the fine arts and the applied arts. The word fine does not so much denote the quality of the artwork in question and this definition originally excluded the applied or decorative arts, and the products of what were regarded as crafts. According to some writers the concept of a category of fine art is an invention of the early modern period in the West. Larry Shiner in his The Invention of Art, A Cultural History locates the invention in the 18th century, There was a traditional “system of the arts” in the West before the eighteenth century. ”Similar ideas have been expressed by Paul Oskar Kristeller, Pierre Bourdieu, and Terry Eagleton, though the point of invention is often placed earlier, in the Italian Renaissance. The separation of arts and crafts that often exists in Europe, in Japanese aesthetics the activities of everyday life are depicted by integrating not only art with craft but man-made with nature. Traditional Chinese art distinguished within Chinese painting between the mostly landscape painting of scholar gentlemen and the artisans of the schools of court painting. A high status was given to many things that would be seen as craft objects in the West, in particular ceramics, jade carving, weaving. Drawing is a form of expression and is one of the major forms of the visual arts. Common instruments include graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, chalk, pastels, markers, stylus, There are a number of subcategories of drawing, including cartooning. Mosaics are images formed with pieces of stone or glass. They can be decorative or functional, an artist who designs and makes mosaics is called a mosaic artist or a mosaicist. Printmaking is the process of making artworks by printing, normally on paper, except in the case of monotyping, the process is capable of producing multiples of the same piece, which is called a print. Each print is considered an original, as opposed to a copy, the reasoning behind this is that the print is not a reproduction of another work of art in a different medium — for instance, a painting — but rather an image designed from inception as a print. An individual print is also referred to as an impression, prints are created from a single original surface, known technically as a matrix. But there are other kinds, discussed below. Multiple nearly identical prints can be called an edition, in modern times each print is often signed and numbered forming a limited edition

Film
–
A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession, the process of filmmaking is both an art and an industry. The word cinema, short for cinematography, is used to refer to the industry of films. Films were originally recorded onto plastic film through a photochemical process, the adoption of CGI-based special effects led to the use of digital intermediates. Most contemporary films are now fully digital through the process of production, distribution. Films recorded in a form traditionally included an analogous optical soundtrack. It runs along a portion of the film exclusively reserved for it and is not projected, Films are cultural artifacts created by specific cultures. They reflect those cultures, and, in turn, affect them, Film is considered to be an important art form, a source of popular entertainment, and a powerful medium for educating—or indoctrinating—citizens. The visual basis of film gives it a power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles to translate the dialog into the language of the viewer, some have criticized the film industrys glorification of violence and its potentially negative treatment of women. The individual images that make up a film are called frames, the perception of motion is due to a psychological effect called phi phenomenon. The name film originates from the fact that film has historically been the medium for recording and displaying motion pictures. Many other terms exist for a motion picture, including picture, picture show, moving picture, photoplay. The most common term in the United States is movie, while in Europe film is preferred. Terms for the field, in general, include the big screen, the screen, the movies, and cinema. In early years, the sheet was sometimes used instead of screen. Preceding film in origin by thousands of years, early plays and dances had elements common to film, scripts, sets, costumes, production, direction, actors, audiences, storyboards, much terminology later used in film theory and criticism apply, such as mise en scène. Owing to the lack of any technology for doing so, the moving images, the magic lantern, probably created by Christiaan Huygens in the 1650s, could be used to project animation, which was achieved by various types of mechanical slides

Video
–
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video systems vary greatly in the resolution of the display and refresh rate, video can be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc. Video was originally exclusively a live technology, charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder. In 1951 the first video tape recorder captured live images from television cameras by converting the electrical impulses. Video recorders were sold for $50,000 in 1956, however, prices gradually dropped over the years, in 1971, Sony began selling videocassette recorder decks and tapes into the consumer market. The use of techniques in video created digital video, which allowed higher quality and, eventually. After the invention of the DVD in 1997 and Blu-ray Disc in 2006, sales of videotape, the advent of digital broadcasting and the subsequent digital television transition is in the process of relegating analog video to the status of a legacy technology in most parts of the world. PAL standards and SECAM specify 25 frame/s, while NTSC standards specify 29.97 frames, film is shot at the slower frame rate of 24 frames per second, which slightly complicates the process of transferring a cinematic motion picture to video. The minimum frame rate to achieve a comfortable illusion of an image is about sixteen frames per second. Video can be interlaced or progressive, analog display devices reproduce each frame in the same way, effectively doubling the frame rate as far as perceptible overall flicker is concerned. NTSC, PAL and SECAM are interlaced formats, abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is specified as 576i50, where 576 indicates the total number of horizontal scan lines, i indicates interlacing. In progressive scan systems, each refresh period updates all scan lines in each frame in sequence, when displaying a natively progressive broadcast or recorded signal, the result is optimum spatial resolution of both the stationary and moving parts of the image. Deinterlacing cannot, however, produce video quality that is equivalent to true progressive scan source material, aspect ratio describes the dimensions of video screens and video picture elements. All popular video formats are rectilinear, and so can be described by a ratio between width and height, the screen aspect ratio of a traditional television screen is 4,3, or about 1.33,1. High definition televisions use a ratio of 16,9. The aspect ratio of a full 35 mm film frame with soundtrack is 1.375,1. Therefore, a 720 by 480 pixel NTSC DV image displayes with the 4,3 aspect ratio if the pixels are thin, the popularity of viewing video on mobile phones has led to the growth of vertical video

Computer graphics
–
Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with help from specialized hardware and software. It is a vast and recent area in computer science, the phrase was coined in 1960, by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, though sometimes referred to as CGI. The overall methodology depends heavily on the sciences of geometry, optics. Computer graphics is responsible for displaying art and image data effectively and meaningfully to the user and it is also used for processing image data received from the physical world. Computer graphic development has had a significant impact on many types of media and has revolutionized animation, movies, advertising, video games, the term computer graphics has been used a broad sense to describe almost everything on computers that is not text or sound. Such imagery is found in and on television, newspapers, weather reports, a well-constructed graph can present complex statistics in a form that is easier to understand and interpret. In the media such graphs are used to illustrate papers, reports, thesis, many tools have been developed to visualize data. Computer generated imagery can be categorized into different types, two dimensional, three dimensional, and animated graphics. As technology has improved, 3D computer graphics have become more common, Computer graphics has emerged as a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Screens could display art since the Lumiere brothers use of mattes to create effects for the earliest films dating from 1895. New kinds of displays were needed to process the wealth of information resulting from such projects, early projects like the Whirlwind and SAGE Projects introduced the CRT as a viable display and interaction interface and introduced the light pen as an input device. Douglas T. Ross of the Whirlwind SAGE system performed an experiment in 1954 in which a small program he wrote captured the movement of his finger. Electronics pioneer Hewlett-Packard went public in 1957 after incorporating the decade prior, and established ties with Stanford University through its founders. This began the transformation of the southern San Francisco Bay Area into the worlds leading computer technology hub - now known as Silicon Valley. The field of computer graphics developed with the emergence of computer graphics hardware, further advances in computing led to greater advancements in interactive computer graphics. In 1959, the TX-2 computer was developed at MITs Lincoln Laboratory, the TX-2 integrated a number of new man-machine interfaces

Bauhaus
–
The Bauhaus was founded by Walter Gropius in Weimar. Nonetheless, it was founded with the idea of creating a work of art in which all arts, including architecture. The Bauhaus style later became one of the most influential currents in modern design, Modernist architecture and art, design, the Bauhaus had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography. Although the school was closed, the continued to spread its idealistic precepts as they left Germany. The changes of venue and leadership resulted in a constant shifting of focus, technique, instructors, many Germans of left-wing views were influenced by the cultural experimentation that followed the Russian Revolution, such as constructivism. Such influences can be overstated, Gropius did not share these radical views, thus, the Bauhaus style, also known as the International Style, was marked by the absence of ornamentation and by harmony between the function of an object or a building and its design. In its first seven years, the Werkbund came to be regarded as the body on questions of design in Germany. The entire movement of German architectural modernism was known as Neues Bauen, beginning in June 1907, Peter Behrens pioneering industrial design work for the German electrical company AEG successfully integrated art and mass production on a large scale. Behrens was a member of the Werkbund, and both Walter Gropius and Adolf Meyer worked for him in this period. The Bauhaus was founded at a time when the German zeitgeist had turned from emotional Expressionism to the matter-of-fact New Objectivity, beyond the Bauhaus, many other significant German-speaking architects in the 1920s responded to the same aesthetic issues and material possibilities as the school. They also responded to the promise of a minimal dwelling written into the new Weimar Constitution, ernst May, Bruno Taut, and Martin Wagner, among others, built large housing blocks in Frankfurt and Berlin. The acceptance of modernist design into everyday life was the subject of publicity campaigns, well-attended public exhibitions like the Weissenhof Estate, films, the Vkhutemas, the Russian state art and technical school founded in 1920 in Moscow, has been compared to Bauhaus. Founded a year after the Bauhaus school, Vkhutemas has close parallels to the German Bauhaus in its intent, organization, the two schools were the first to train artist-designers in a modern manner. Vkhutemas was a school than the Bauhaus, but it was less publicised outside the Soviet Union. With the internationalism of modern architecture and design, there were exchanges between the Vkhutemas and the Bauhaus. In addition, El Lissitzkys book Russia, an Architecture for World Revolution published in German in 1930 featured several illustrations of Vkhutemas/Vkhutein projects there. The school was founded by Walter Gropius in Weimar in 1919 as a merger of the Grand Ducal School of Arts and Crafts and the Weimar Academy of Fine Art. Its roots lay in the arts and crafts founded by the Grand Duke of Saxe-Weimar-Eisenach in 1906

Futurism
–
Futurism was an artistic and social movement that originated in Italy in the early 20th century. It emphasized speed, technology, youth, and violence, and objects such as the car, the aeroplane, although it was largely an Italian phenomenon, there were parallel movements in Russia, England, Belgium and elsewhere. It glorified modernity and aimed to liberate Italy from the weight of its past, Cubism contributed to the formation of Italian Futurisms artistic style. Important Futurist works included Marinettis Manifesto of Futurism, Boccionis sculpture Unique Forms of Continuity in Space, to some extent Futurism influenced the art movements Art Deco, Constructivism, Surrealism, Dada, and to a greater degree Precisionism, Rayonism, and Vorticism. Futurism is a movement founded in Milan in 1909 by the Italian poet Filippo Tommaso Marinetti. He was soon joined by the painters Umberto Boccioni, Carlo Carrà, Giacomo Balla, Gino Severini, Marinetti expressed a passionate loathing of everything old, especially political and artistic tradition. We want no part of it, the past, he wrote, publishing manifestos was a feature of Futurism, and the Futurists wrote them on many topics, including painting, architecture, religion, clothing and cooking. The founding manifesto did not contain an artistic programme, which the Futurists attempted to create in their subsequent Technical Manifesto of Futurist Painting. This committed them to a universal dynamism, which was to be represented in painting. The motor bus rushes into the houses which it passes, the Futurist painters were slow to develop a distinctive style and subject matter. In 1910 and 1911 they used the techniques of Divisionism, breaking light and color down into a field of stippled dots and stripes, which had been originally created by Giovanni Segantini and others. Later, Severini, who lived in Paris, attributed their backwardness in style and method at this time to their distance from Paris, the centre of avant-garde art. Severini was the first to come into contact with Cubism and following a visit to Paris in 1911 the Futurist painters adopted the methods of the Cubists, Cubism offered them a means of analysing energy in paintings and expressing dynamism. They often painted modern urban scenes, carràs Funeral of the Anarchist Galli is a large canvas representing events that the artist had himself been involved in, in 1904. The action of an attack and riot is rendered energetically with diagonals. His Leaving the Theatre uses a Divisionist technique to render isolated, Boccionis The City Rises represents scenes of construction and manual labour with a huge, rearing red horse in the centre foreground, which workmen struggle to control. The Futurists aimed through their art thus to enable the viewer to apprehend the inner being of what they depicted, Boccioni developed these ideas at length in his book, Pittura scultura Futuriste, Dinamismo plastico. Ballas Dynamism of a Dog on a Leash exemplifies the Futurists insistence that the world is in constant movement

Hirshhorn Museum and Sculpture Garden
–
The Hirshhorn Museum and Sculpture Garden is an art museum beside the National Mall, in Washington, D. C. the United States. The museum was endowed during the 1960s with the permanent art collection of Joseph H. Hirshhorn. It was designed by architect Gordon Bunshaft and is part of the Smithsonian Institution, the Hirshhorn is sited halfway between the Washington Monument and the US Capitol, anchoring the southernmost end of the so-called L’Enfant axis. The building itself is an attraction, an open cylinder elevated on four massive legs, in the late 1930s, the United States Congress mandated an art museum for the National Mall. At the time, the venue for visual art was the National Gallery of Art, which focuses on Dutch, French. During the 1940s World War II shifted the project into the background, meanwhile, Joseph H. Then, in 1955, Hirshhorn sold his uranium interests for more than $50-million. He expanded his collection to warehouses, an apartment in New York City, a 1962 sculpture show at New Yorks Guggenheim Museum awakened an international art community to the breadth of Hirshhorns holdings. Word of his collection of modern and contemporary paintings also circulated, and institutions in Italy, Israel, Canada, California, president Lyndon B. Johnson and Smithsonian Secretary S. Dillon Ripley successfully campaigned for a new museum on the National Mall. In 1966, an Act of Congress established the Hirshhorn Museum and Sculpture Garden, most of the funding was federal, but Hirshhorn later contributed $1-million toward construction. Joseph and his wife, Olga Zatorsky Hirshhorn, visited the White House. The groundbreaking was in 1969 and Abram Lerner was named the founding Director and he oversaw research, conservation, and installation of more than 6,000 items brought from the Hirshhorns Connecticut estate and other properties to Washington, DC. What I accomplished in the United States I could not have accomplished anywhere else in the world, one million visitors saw the 850-work inaugural show in the first six months. In 1984, James T. Demetrion, fourteen-year director of the Des Moines Art Center in Iowa, Art collector and retail store founder Sydney Lewis of Richmond, Virginia, succeeded Senator Daniel P. Moynihan as board chairman. Mr. Demetrion held the post for more than 17 years, ned Rifkin became director in February 2002, returning to the Hirshhorn after directorship positions at the Menil Collection in Texas and the High Museum of Art in Atlanta, Georgia. Rifkin was previously curator of the Hirshhorn from 1986 until 1991. In October 2003, Rifkin was named Under Secretary for Art of the Smithsonian, in 2005, Olga Viso was named director of the Hirshhorn. Viso joined the department of the Hirshhorn in 1995 as assistant curator, was named associate curator in 1998. In October 2003, Viso was named deputy director of the Hirshhorn, after two years, Ms. Viso accepted the position of Director of the Walker Art Center in Minneapolis, departing in December 2007

Cathode ray tube
–
The cathode ray tube is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images. It modulates, accelerates, and deflects electron beam onto the screen to create the images, the images may represent electrical waveforms, pictures, radar targets, or others. CRTs have also used as memory devices, in which case the visible light emitted from the fluorescent material is not intended to have significant meaning to a visual observer. In television sets and computer monitors, the 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 beams, one for each additive primary color with a video signal as a reference. A CRT is constructed from an envelope which is large, deep, fairly heavy. The interior of a CRT is evacuated to approximately 0.01 Pa to 133 nPa. evacuation being necessary to facilitate the flight of electrons from the gun to the tubes face. That it is evacuated makes handling an intact CRT potentially dangerous due to the risk of breaking the tube and causing a violent implosion that can hurl shards of glass at great velocity. As a matter of safety, the face is made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions. Flat panel displays can also be made in large sizes, whereas 38 to 40 was about the largest size of a CRT television, flat panels are available in 60. Cathode rays were discovered by Johann Hittorf in 1869 in primitive Crookes tubes and he observed that some unknown rays were emitted from the cathode which could cast shadows on the glowing wall of the tube, indicating the rays were traveling in straight lines. In 1890, Arthur Schuster demonstrated cathode rays could be deflected by electric fields, the earliest version of the CRT was known as the Braun tube, invented by the German physicist Ferdinand Braun in 1897. It was a diode, a modification of the Crookes tube with a phosphor-coated screen. In 1907, Russian scientist Boris Rosing used a CRT in the end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen, which marked the first time that CRT technology was used for what is now known as television. The first cathode ray tube to use a hot cathode was developed by John B. Johnson and Harry Weiner Weinhart of Western Electric and it was named by inventor Vladimir K. Zworykin in 1929. RCA was granted a trademark for the term in 1932, it released the term to the public domain in 1950. The first commercially made electronic television sets with cathode ray tubes were manufactured by Telefunken in Germany in 1934, in oscilloscope CRTs, electrostatic deflection is used, rather than the magnetic deflection commonly used with television and other large CRTs

MIDI
–
A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device. These messages are sent via a MIDI cable to other devices where they control sound generation, a simple example of a MIDI setup is the use of a MIDI controller such as an electronic musical keyboard to trigger sounds created by a sound module. This MIDI data can also be recorded into a hardware or software device called a sequencer, advantages of MIDI include compactness, ease of modification and manipulation and a wide choice of electronic instruments and synthesizer or digitally-sampled sounds. MIDI technology was standardized in 1983 by a panel of industry representatives. In June 1981, Roland founder Ikutaro Kakehashi proposed the idea of standardization to Oberheim Electronics founder Tom Oberheim, in October 1981, Kakehashi, Oberheim and Smith discussed the idea with representatives from Yamaha, Korg and Kawai. Smith proposed this standard at the Audio Engineering Society show in November 1981, MIDIs development was announced to the public by Robert Moog, in the October 1982 edition of Keyboard magazine. By the time of the January 1983 Winter NAMM Show, Smith was able to demonstrate a MIDI connection between his Prophet 600 analog synthesizer and a Roland JP-6, the MIDI Specification was published in August 1983. The MIDI standard was unveiled by Ikutaro Kakehashi and Dave Smith, MIDIs appeal was originally limited to professional musicians and record producers who wanted to use electronic instruments in the production of popular music. The standard allowed different instruments to speak with other and with computers. This interoperability allowed one device to be controlled from another, which reduced the amount of hardware musicians needed to own, MIDIs introduction coincided with the dawn of the personal computer era and the introductions of samplers and digital synthesizers. The creative possibilities brought about by MIDI technology have been credited as having helped to revive the industry in the 1980s. MIDI introduced many capabilities which transformed the way musicians work, MIDI sequencing made it possible for a user with no notation skills to build complex arrangements. A musical act with as few as one or two members, each operating multiple MIDI-enabled devices, could deliver a performance which sounds similar to that of a larger group of musicians. By performing preproduction in an environment, an artist can reduce recording costs by arriving at a recording studio with a song that is already partially completed and worked out. Educational technology enabled by MIDI has transformed music education and those new to the subject of MIDI might confuse it with digital audio. MIDI symbolically represents a note, whereas digital audio represents the sound produced by the note, MIDI was invented so that musical instruments could communicate with each other and so that one instrument can control another. Analog synthesizers that have no digital component and were built prior to MIDIs development can be retrofit with kits that convert MIDI messages into analog control voltages. When a note is played on a MIDI instrument, it generates a signal that can be used to trigger a note on another instrument
