Learning Objectives

1. Place two technological developments that paved the way for the evolution of tv.
2. Explain why electronic boob tube prevailed over mechanical tv set.
3. Identify three important developments in the history of television since 1960.

Since replacing radio as the virtually popular mass medium in the 1950s, goggle box has played such an integral office in modern life that, for some, it is difficult to imagine beingness without it. Both reflecting and shaping cultural values, boob tube has at times been criticized for its declared negative influences on children and young people and at other times lauded for its ability to create a common experience for all its viewers. Major world events such as the John F. Kennedy and Martin Luther Male monarch assassinations and the Vietnam War in the 1960s, the Challenger shuttle explosion in 1986, the 2001 terrorist attacks on the Globe Trade Center, and the impact and backwash of Hurricane Katrina in 2005 have all played out on television, uniting millions of people in shared tragedy and hope. Today, as Internet applied science and satellite broadcasting change the way people sentinel television receiver, the medium continues to evolve, solidifying its position as i of the near important inventions of the 20th century.

The Origins of Television receiver

Inventors conceived the thought of television long before the applied science to create information technology appeared. Early pioneers speculated that if audio waves could be separated from the electromagnetic spectrum to create radio, and so too could Idiot box waves be separated to transmit visual images. As early as 1876, Boston civil servant George Carey envisioned complete idiot box systems, putting forward drawings for a "selenium camera" that would enable people to "see past electricity" a year later (Federal Communications Commission, 2005).

During the tardily 1800s, several technological developments set the stage for idiot box. The invention of the cathode ray tube (CRT) by German language physicist Karl Ferdinand Braun in 1897 played a vital role as the forerunner of the TV film tube. Initially created as a scanning device known equally the cathode ray oscilloscope, the CRT finer combined the principles of the camera and electricity. Information technology had a fluorescent screen that emitted a visible calorie-free (in the form of images) when struck by a beam of electrons. The other key invention during the 1880s was the mechanical scanner system. Created by High german inventor Paul Nipkow, the scanning disk was a large, flat metal disk with a series of pocket-sized perforations arranged in a screw pattern. As the disk rotated, low-cal passed through the holes, separating pictures into pinpoints of calorie-free that could be transmitted as a series of electronic lines. The number of scanned lines equaled the number of perforations, and each rotation of the disk produced a tv set frame. Nipkow'south mechanical disk served equally the foundation for experiments on the transmission of visual images for several decades.

In 1907, Russian scientist Boris Rosing used both the CRT and the mechanical scanner organization in an experimental television set system. With the CRT in the receiver, he used focused electron beams to brandish images, transmitting crude geometrical patterns onto the television screen. The mechanical disk system was used as a camera, creating a primitive television system.

Figure 9.1

Two fundamental inventions in the 1880s paved the style for television set to sally: the cathode ray tube and the mechanical disk system.

Mechanical Television receiver versus Electronic Boob tube

From the early experiments with visual transmissions, two types of television receiver systems came into existence: mechanical television and electronic television receiver. Mechanical television developed out of Nipkow'due south disk arrangement and was pioneered past British inventor John Logie Baird. In 1926, Baird gave the world'due south first public demonstration of a tv system at Selfridge'due south department shop in London. He used mechanical rotating disks to scan moving images into electrical impulses, which were transmitted past cablevision to a screen. Here they showed up equally a depression-resolution blueprint of light and dark. Baird'due south outset goggle box programme showed the heads of 2 ventriloquist dummies, which he operated in front of the camera appliance out of the audience's sight. In 1928, Baird extended his organisation by transmitting a indicate between London and New York. The following year, the British Broadcasting Corporation (BBC) adopted his mechanical system, and past 1932, Baird had developed the first commercially viable television organization and sold 10,000 sets. Despite its initial success, mechanical boob tube had several technical limitations. Engineers could get no more than about 240 lines of resolution, meaning images would always exist slightly fuzzy (most modern televisions produce images of more than 600 lines of resolution). The use of a spinning disk likewise limited the number of new pictures that could be seen per second, resulting in excessive flickering. The mechanical attribute of television proved to be a disadvantage that required fixing in order for the technology to motion forward.

At the same time Baird (and, separately, American inventor Charles Jenkins) was developing the mechanical model, other inventors were working on an electronic television system based on the CRT. While working on his male parent'due south farm, Idaho teenager Philo Farnsworth realized that an electronic beam could browse a flick in horizontal lines, reproducing the image almost instantaneously. In 1927, Farnsworth transmitted the first all-electronic TV picture by rotating a unmarried straight line scratched onto a square piece of painted glass by 90 degrees.

Farnsworth barely profited from his invention; during Earth War Ii, the government suspended sales of Tv set sets, and by the fourth dimension the war ended, Farnsworth's original patents were shut to expiring. However, following the state of war, many of his key patents were modified by RCA and were widely applied in dissemination to improve television set picture quality.

Having coexisted for several years, electronic television sets eventually began to replace mechanical systems. With better flick quality, no noise, a more than compact size, and fewer visual limitations, the electronic arrangement was far superior to its predecessor and rapidly improving. By 1939, the last mechanical television broadcasts in the U.s.a. had been replaced with electronic broadcasts.

Early Broadcasting

Television broadcasting began as early on as 1928, when the Federal Radio Committee authorized inventor Charles Jenkins to broadcast from W3XK, an experimental station in the Maryland suburbs of Washington, DC. Silhouette images from motion picture films were broadcast to the general public on a regular basis, at a resolution of just 48 lines. Similar experimental stations ran broadcasts throughout the early on 1930s. In 1939, RCA subsidiary NBC (National Broadcasting Visitor) became the first network to introduce regular television broadcasts, transmitting its inaugural telecast of the opening ceremonies at the New York World'southward Fair. The station'southward initial broadcasts transmitted to just 400 television sets in the New York surface area, with an audience of 5,000 to 8,000 people (Lohr, 1940).

Idiot box was initially bachelor only to the privileged few, with sets ranging from $200 to $600—a hefty sum in the 1930s, when the average annual salary was $i,368 (KC Library). RCA offered four types of television receivers, which were sold in high-end department stores such every bit Macy'due south and Bloomingdale's, and received channels 1 through five. Early receivers were a fraction of the size of modern Television receiver sets, featuring 5-, nine-, or 12-inch screens. Television sales prior to Globe State of war 2 were disappointing—an uncertain economical climate, the threat of war, the high price of a television receiver, and the limited number of programs on offer deterred numerous prospective buyers. Many unsold television sets were put into storage and sold later on the war.

NBC was not the just commercial network to sally in the 1930s. RCA radio rival CBS (Columbia Broadcasting System) also began dissemination regular programs. So that viewers would non demand a separate tv set set for each individual network, the Federal Communications Commission (FCC) outlined a unmarried technical standard. In 1941, the panel recommended a 525-line organisation and an image rate of thirty frames per second. It also recommended that all U.S. tv set sets operate using analog signals (broadcast signals made of varying radio waves). Analog signals were replaced by digital signals (signals transmitted equally binary code) in 2009.

With the outbreak of World War II, many companies, including RCA and General Electric, turned their attending to military production. Instead of commercial television sets, they began to churn out military electronic equipment. In improver, the war halted well-nigh all television broadcasting; many Tv stations reduced their schedules to around iv hours per week or went off the air altogether.

Color Technology

Although it did not become available until the 1950s or popular until the 1960s, the engineering science for producing color telly was proposed as early on as 1904, and was demonstrated past John Logie Baird in 1928. As with his black-and-white television organization, Baird adopted the mechanical method, using a Nipkow scanning disk with 3 spirals, i for each principal color (cherry, green, and blue). In 1940, CBS researchers, led by Hungarian television engineer Peter Goldmark, used Baird'southward 1928 designs to develop a concept of mechanical color television that could reproduce the color seen by a photographic camera lens.

Following World War II, the National Telly System Committee (NTSC) worked to develop an all-electronic color organisation that was compatible with black-and-white Tv sets, gaining FCC blessing in 1953. A year later, NBC fabricated the start national color broadcast when information technology telecast the Tournament of Roses Parade. Despite the television manufacture'southward support for the new technology, it would be another 10 years before color television gained widespread popularity in the Us, and black-and-white Television set sets outnumbered color TV sets until 1972 (Klooster, 2009).

The Gilded Age of Goggle box

Effigy 9.three

During the so-chosen "gilt age" of telly, the percentage of U.S. households that owned a boob tube set rose from 9 per centum in 1950 to 95.iii percent in 1970.

The 1950s proved to be the golden age of television, during which the medium experienced massive growth in popularity. Mass-production advances made during World War II essentially lowered the cost of purchasing a set, making television receiver accessible to the masses. In 1945, in that location were fewer than 10,000 Idiot box sets in the Usa. By 1950, this figure had soared to effectually 6 million, and by 1960 more than than sixty million television sets had been sold (Earth Book Encyclopedia, 2003). Many of the early on television program formats were based on network radio shows and did not accept advantage of the potential offered by the new medium. For instance, newscasters but read the news as they would have during a radio broadcast, and the network relied on newsreel companies to provide footage of news events. Even so, during the early 1950s, boob tube programming began to branch out from radio broadcasting, borrowing from theater to create acclaimed dramatic anthologies such as Playhouse 90 (1956) and The U.S. Steel Hour (1953) and producing quality news motion-picture show to accompany coverage of daily events.

Two new types of programs—the magazine format and the TV spectacular—played an important role in helping the networks gain control over the content of their broadcasts. Early television programs were developed and produced by a single sponsor, which gave the sponsor a large amount of control over the content of the testify. By increasing programme length from the standard xv-minute radio show to 30 minutes or longer, the networks substantially increased advertisement costs for programme sponsors, making it prohibitive for a single sponsor. Magazine programs such as the Today bear witness and The Tonight Show, which premiered in the early 1950s, featured multiple segments and ran for several hours. They were also screened on a daily, rather than weekly, basis, drastically increasing advertizement costs. As a result, the networks began to sell spot advertisements that ran for 30 or 60 seconds. Similarly, the idiot box spectacular (now known every bit the television special) featured lengthy music-diversity shows that were sponsored past multiple advertisers.

In the mid-1950s, the networks brought back the radio quiz-show genre. Cheap and easy to produce, the tendency defenseless on, and by the terminate of the 1957–1958 flavour, 22 quiz shows were being aired on network television, including CBS's $64,000 Question. Shorter than some of the new types of programs, quiz shows enabled single corporate sponsors to take their names displayed on the ready throughout the show. The popularity of the quiz-prove genre plunged at the end of the decade, however, when it was discovered that virtually of the shows were rigged. Producers provided some contestants with the answers to the questions in gild to option and cull the most likable or controversial candidates. When a slew of contestants accused the show Dotto of existence stock-still in 1958, the networks rapidly dropped 20 quiz shows. A New York yard jury probe and a 1959 congressional investigation finer ended prime-time quiz shows for 40 years, until ABC revived the genre with its launch of Who Wants to Be a Millionaire in 1999 (Boddy, 1990).

The Rising of Cablevision Boob tube

Formerly known equally Community Antenna Tv set, or CATV, cable television was originally developed in the 1940s in remote or mountainous areas, including in Arkansas, Oregon, and Pennsylvania, to heighten poor reception of regular television signals. Cable antennas were erected on mountains or other high points, and homes connected to the towers would receive broadcast signals.

In the late 1950s, cable operators began to experiment with microwave to bring signals from distant cities. Taking advantage of their ability to receive long-altitude broadcast signals, operators branched out from providing a local customs service and began focusing on offering consumers more all-encompassing programming choices. Rural parts of Pennsylvania, which had just iii channels (one for each network), soon had more than double the original number of channels every bit operators began to import programs from independent stations in New York and Philadelphia. The wider multifariousness of channels and clearer reception the service offered soon attracted viewers from urban areas. By 1962, nearly 800 cable systems were operational, serving 850,000 subscribers.

The Evolution of Goggle box

Cable's exponential growth was viewed as contest by local Tv set stations, and broadcasters campaigned for the FCC to footstep in. The FCC responded by placing restrictions on the ability of cable systems to import signals from distant stations, which froze the evolution of cable television in major markets until the early 1970s. When gradual deregulation began to loosen the restrictions, cable operator Service Electric launched the service that would alter the face of the cable television industry—pay TV. The 1972 Home Box Function (HBO) venture, in which customers paid a subscription fee to access premium cable goggle box shows and video-on-demand products, was the nation'southward first successful pay cable service. HBO'southward apply of a satellite to distribute its programming made the network available throughout the United States. This gave it an advantage over the microwave-distributed services, and other cable providers chop-chop followed conform. Further deregulation provided by the 1984 Cable Act enabled the industry to aggrandize even further, and by the end of the 1980s, near 53 one thousand thousand households subscribed to cable television (see Section 6.3 "Current Popular Trends in the Music Industry"). In the 1990s, cable operators upgraded their systems by building higher-capacity hybrid networks of fiber-optic and coaxial cable. These broadband networks provide a multichannel television set service, along with phone, high-speed Internet, and advanced digital video services, using a unmarried wire.

The Emergence of Digital Television

Following the FCC standards set up out during the early 1940s, television sets received programs via analog signals made of radio waves. The analog signal reached Television sets through three dissimilar methods: over the airwaves, through a cablevision wire, or by satellite transmission. Although the arrangement remained in place for more threescore years, it had several disadvantages. Analog systems were decumbent to static and distortion, resulting in a far poorer picture quality than films shown in movie theaters. Equally television sets grew increasingly larger, the express resolution made scan lines painfully obvious, reducing the clarity of the image. Companies around the world, most notably in Japan, began to develop technology that provided newer, ameliorate-quality television formats, and the broadcasting manufacture began to anteroom the FCC to create a committee to report the desirability and impact of switching to digital television. A more efficient and flexible form of circulate applied science, digital television uses signals that translate Television images and sounds into binary code, working in much the same way as a computer. This means they crave much less frequency space and also provide a far higher quality film. In 1987, the Informational Committee on Advanced Television Services began meeting to test diverse TV systems, both analog and digital. The committee ultimately agreed to switch from analog to digital format in 2009, allowing a transition flow in which broadcasters could send their signal on both an analog and a digital channel. Once the switch took place, many older analog TV sets were unusable without a cable or satellite service or a digital converter. To retain consumers' access to gratis over-the-air television, the federal authorities offered $xl souvenir cards to people who needed to buy a digital converter, expecting to recoup its costs by auctioning off the old analog broadcast spectrum to wireless companies (Steinberg, 2007). These companies were eager to gain admission to the analog spectrum for mobile broadband projects because this frequency band allows signals to travel greater distances and penetrate buildings more easily.

The Era of Loftier-Definition Television

Around the same time the U.Due south. authorities was reviewing the options for analog and digital television systems, companies in Japan were developing technology that worked in conjunction with digital signals to create crystal-clear pictures in a wide-screen format. High-definition telly, or HDTV, attempts to create a heightened sense of realism past providing the viewer with an almost three-dimensional feel. It has a much higher resolution than standard television systems, using effectually 5 times every bit many pixels per frame. Beginning bachelor in 1998, HDTV products were initially extremely expensive, priced between $5,000 and $10,000 per ready. Nevertheless, every bit with most new technology, prices dropped considerably over the next few years, making HDTV affordable for mainstream shoppers.

Figure nine.half-dozen

HDTV uses a wide-screen format with a dissimilar attribute ratio (the ratio of the width of the epitome to its meridian) than standard-definition Television set. The wide-screen format of HDTV is like to that of movies, allowing for a more authentic pic-viewing experience at home.

As of 2010, near one-half of American viewers are watching television in high definition, the fastest adoption of TV applied science since the introduction of the VCR in the 1980s (Stelter, 2010). The new technology is alluring viewers to scout television for longer periods of fourth dimension. According to the Nielsen Company, a company that measures Tv viewership, households with HDTV scout three percent more than prime-fourth dimension television—programming screened between 7 and eleven p.m., when the largest audition is available—than their standard-definition counterparts (Stelter, 2010). The same report claims that the cinematic experience of HDTV is bringing families back together in the living room in front of the big wide-screen TV and out of the kitchen and sleeping accommodation, where individuals tend to lookout television lonely on smaller screens. Notwithstanding, these viewing patterns may change again shortly every bit the Net plays an increasingly larger role in how people view Telly programs. The affect of new technologies on television is discussed in much greater detail in Section 9.4 "Influence of New Technologies" of this chapter.

Since 1950, the amount of fourth dimension the boilerplate household spends watching television has virtually doubled.

Key Takeaways

• Ii key technological developments in the late 1800s played a vital role in the development of television: the cathode ray tube and the scanning disk. The cathode ray tube, invented by German language physicist Karl Ferdinand Braun in 1897, was the forerunner of the TV motion picture tube. It had a fluorescent screen that emitted a visible light (in the form of images) when struck by a beam of electrons. The scanning deejay, invented by High german inventor Paul Nipkow, was a large, flat metallic disk that could be used as a rotating camera. It served equally the foundation for experiments on the transmission of visual images for several decades.
• Out of the cathode ray tube and the scanning disk, two types of primitive television systems evolved: mechanical systems and electronic systems. Mechanical television systems had several technical disadvantages: Depression resolution caused fuzzy images, and the use of a spinning deejay limited the number of new pictures that could be seen per 2d, resulting in excessive flickering. By 1939, all mechanical television broadcasts in the United States had been replaced past electronic broadcasts.
• Early on televisions were expensive, and the technology was tedious to take hold of on because evolution was delayed during World State of war Two. Colour technology was delayed even further because early colour systems were incompatible with black-and-white boob tube sets. Following the war, telly rapidly replaced radio equally the new mass medium. During the "golden age" of television set in the 1950s, boob tube moved abroad from radio formats and developed new types of shows, including the magazine-fashion diversity show and the television spectacular.
• Since 1960, several cardinal technological developments accept taken place in the television set industry. Color television gained popularity in the late 1960s and began to supplant blackness-and-white television in the 1970s. Cable television, initially developed in the 1940s to cater to viewers in rural areas, switched its focus from local to national television, offering an extensive number of channels. In 2009, the traditional analog system, which had been in identify for threescore years, was replaced with digital boob tube, giving viewers a higher-quality picture and freeing up frequency space. As of 2010, nearly half of American viewers have high-definition goggle box, which offers a crystal-clear picture in wide-screen to provide a cinematic experience at home.
