Public opinion , or popular opinion , is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them.
148-576: The Hollowmen is an Australian television comedy series set in the offices of the Central Policy Unit, a fictional political advisory unit personally set up by the Prime Minister to help him get re-elected. Their brief is long-term vision; to stop worrying about tomorrow's headlines, and focus on next week's. The Hollowmen was first broadcast on Wednesday, 9 July 2008, on ABC1 . Each series comprises six half-hour episodes. On
296-458: A patent interference suit against Farnsworth. The U.S. Patent Office examiner disagreed in a 1935 decision, finding priority of invention for Farnsworth against Zworykin. Farnsworth claimed that Zworykin's 1923 system could not produce an electrical image of the type to challenge his patent. Zworykin received a patent in 1928 for a color transmission version of his 1923 patent application. He also divided his original application in 1931. Zworykin
444-478: A resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p , 1080i and 720p . Since 2010, with the invention of smart television , Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Prime Video , iPlayer and Hulu . In 2013, 79% of the world's households owned
592-618: A transistor -based UHF tuner . The first fully transistorized color television in the United States was the Quasar television introduced in 1967. These developments made watching color television a more flexible and convenient proposition. In 1972, sales of color sets finally surpassed sales of black-and-white sets. Color broadcasting in Europe was not standardized on the PAL format until
740-467: A tuner for receiving and decoding broadcast signals. A visual display device that lacks a tuner is correctly called a video monitor rather than a television. The television broadcasts are mainly a simplex broadcast meaning that the transmitter cannot receive and the receiver cannot transmit. The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. The first documented usage of
888-483: A 1925 demonstration, the image was dim, had low contrast and poor definition, and was stationary. Zworykin's imaging tube never got beyond the laboratory stage. However, RCA, which acquired the Westinghouse patent, asserted that the patent for Farnsworth's 1927 image dissector was written so broadly that it would exclude any other electronic imaging device. Thus, based on Zworykin's 1923 patent application, RCA filed
1036-403: A 2-inch-wide by 2.5-inch-high screen (5 by 6 cm). The large receiver had a screen 24 inches wide by 30 inches high (60 by 75 cm). Both sets could reproduce 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
1184-544: A Liberal government. It won the 2009 Logie for Most Outstanding Comedy Program . In 2008 the Sydney Morning Herald interviewed political advisors about the accuracy of the show. Political advisors noted that the characters were more cynical and amoral than them and their colleagues, and played to people's prejudices, but a few conceded that they knew people like Rob Sitch 's character, Tony. They found that pollsters were portrayed as having too much power in
1332-402: A TV system with a 40-line resolution that employed a CRT display. This was the first working example of a fully electronic television receiver and Takayanagi's team later made improvements to this system parallel to other television developments. Takayanagi did not apply for a patent. In the 1930s, Allen B. DuMont made the first CRTs to last 1,000 hours of use, one of the factors that led to
1480-683: A camera tube, using the CRT instead as a flying-spot scanner to scan slides and film. Ardenne achieved his first transmission of television pictures on 24 December 1933, followed by test runs for a public television service in 1934. The world's first electronically scanned television service then started in Berlin in 1935, the Fernsehsender Paul Nipkow , culminating in the live broadcast of the 1936 Summer Olympic Games from Berlin to public places all over Germany. Philo Farnsworth gave
1628-504: A challenge that modern presidents face when trying to persuade public opinion is that there is so many different types of media, that getting people's attention is hard. New media alternatives has also caused on effect on presidential leadership as they now use them to be able to communicate younger generations, but targeting small groups of people. According to the Social Science Research Council , "We are in

The former assumption interprets individual, group and official action as part of a single system and reduces politics and governmental policies to
1924-500: A closed and largely illiterate public became an open and politicized one, was to become of tremendous political importance in the 19th century as the mass media was circulated ever more widely and literacy was steadily improved. Governments increasingly recognized the importance of managing and directing public opinion . This trend is exemplified in the career of George Canning who restyled his political career from its aristocratic origins to one of popular consent when he contested and won
2072-609: A color television combining a traditional black-and-white display with a rotating colored disk. This device was very "deep" but was later improved with a mirror folding the light path into an entirely practical device resembling a large conventional console. However, Baird was unhappy with the design, and, as early as 1944, had commented to a British government committee that a fully electronic device would be better. In 1939, Hungarian engineer Peter Carl Goldmark introduced an electro-mechanical system while at CBS , which contained an Iconoscope sensor. The CBS field-sequential color system
2220-409: A communal viewing experience to a solitary viewing experience. By 1960, Sony had sold over 4 million portable television sets worldwide. 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
2368-546: A derivative of three basic analytical terms: society, culture and personality . Despite philosophical arguments regarding public opinion, social scientists (those in sociology , political science , economics and social psychology ) present compelling theories to describe how public opinion shapes public policy and find myriad effects of opinion on policy using various empirical research methods. Moreover, researchers find that causal relationships likely run in both directions from opinion to policy and from policy to opinion. On
2516-483: A different perspective of mass media effects. The study examines the media coverage of firearm-related incidents involving children. The study identifies three main frameworks the media framed these types of incidents: blameless accidents, accidental shootings that occurred in the context of play such as hunting; criminalization, both the children and the parents were arrested and charged; and responsibilization, blame on irresponsible parents and gun owners. There have been
2664-448: A false vision where the perceived truth can actually be very far away from the actual truth. When asked for their opinion on a subject about which they are uninformed, people often provide pseudo-opinions they believe will please the questioner. Public opinion can be influenced by public relations and the political media . Additionally, mass media utilizes a wide variety of advertising techniques to get their message out and change
2812-819: A fellow of the Royal Society (UK), published a letter in the scientific journal Nature in which he described how "distant electric vision" could be achieved by using a cathode-ray tube, or Braun tube, as both a transmitting and receiving device, he expanded on his vision in a speech given in London in 1911 and reported in The Times and the Journal of the Röntgen Society. In a letter to Nature published in October 1926, Campbell-Swinton also announced
2960-423: A lensed disk scanner with a 48-line resolution. He was granted U.S. Patent No. 1,544,156 (Transmitting Pictures over Wireless) on 30 June 1925 (filed 13 March 1922). Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on 7 April 1927. Their reflected-light television system included both small and large viewing screens. The small receiver had

Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on 24 August 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning

The slang term "the tube" or the "boob tube" derives from the bulky cathode-ray tube used on most TVs until the advent of flat-screen TVs . Another slang term for the TV is "idiot box." Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century. Alexander Bain introduced
3404-643: A model diverges from the prior paradigm of the "two-step" process. The Watts and Dodds model introduces a model of influence emphasizing lateral channels of influence between the influencers and general public categories. Thus, this leads to a more complex flow of influence amongst the three parties involved in influencing public opinion (i.e. media, influencers and general public). Influentials shape opinion through producing testimonials, celebrity endorsement, and expert opinions. Furthermore, they also have credibility and emotional appeal. Their believes shaped from their experiences and academic knowledge provide foundation to
3552-485: A particular clientele divided by occupation or attitude, such as Tories and Whigs , wits and stockjobbers , merchants and lawyers, booksellers and authors, men of fashion or the "cits" of the old city center . Joseph Addison wanted to have it said of him that he had "brought philosophy out of closets and libraries to dwell in clubs and assemblies, at tea tables and in coffee houses". According to one French visitor, Antoine François Prévost , coffeehouses, "where you have
3700-442: 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 1944 was the first example of a practical color television system. Work on
3848-471: A production model was halted by the SCAP after World War II . Because only a limited number of holes could be made in the disks, and disks beyond a certain diameter became impractical, image resolution on mechanical television broadcasts was relatively low, ranging from about 30 lines up to 120 or so. Nevertheless, the image quality of 30-line transmissions steadily improved with technical advances, and by 1933
3996-506: A projection screen at London's Dominion Theatre . Mechanically scanned color television was also demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells , amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full-color image. The first practical hybrid system was again pioneered by John Logie Baird. In 1940 he publicly demonstrated
4144-591: A radio link from Whippany, New Jersey . Comparing the two transmission methods, viewers noted no difference in quality. Subjects of the telecast included Secretary of Commerce Herbert Hoover . A flying-spot scanner beam illuminated these subjects. The scanner that produced the beam had a 50-aperture disk. The disc revolved at a rate of 18 frames per second, capturing one frame about every 56 milliseconds . (Today's systems typically transmit 30 or 60 frames per second, or one frame every 33.3 or 16.7 milliseconds, respectively.) Television historian Albert Abramson underscored
4292-616: A resolution that was not surpassed until May 1932 by RCA, with 120 lines. On 25 December 1926, Kenjiro Takayanagi demonstrated a television system with a 40-line resolution that employed a Nipkow disk scanner and CRT display at Hamamatsu Industrial High School in Japan. This prototype is still on display at the Takayanagi Memorial Museum in Shizuoka University , Hamamatsu Campus. His research in creating

More generally, coffee houses became meeting places where business could be carried on, news exchanged and The London Gazette (government announcements) read. Lloyd's of London had its origins in a coffeehouse run by Edward Lloyd , where underwriters of ship insurance met to do business. By 1739, there were 551 coffeehouses in London. Each attracted
4588-424: A role in policy implementation. It is said to be one of the first large-scale empirical examinations regarding citizen involvement in policy. It results indicate that between democratic and administrative decision making, there is a trade-off. Citizen input provides administrators with important and valuable information. Citizen input also helps to push the efficiency and effectiveness of public programs. However, there

4736-641: A signal reportedly to the 60th power or better and showed great promise in all fields of electronics. Unfortunately, an issue with the multipactor was that it wore out at an unsatisfactory rate. At the Berlin Radio Show in August 1931 in Berlin , Manfred von Ardenne gave a public demonstration of a television system using a CRT for both transmission and reception, the first completely electronic television transmission. However, Ardenne had not developed
4884-404: A significant force in the political realm dates to the late 17th century, but opinion had been regarded as having singular importance much earlier. Medieval fama publica or vox et fama communis had great legal and social importance from the 12th and 13th centuries onward. Later, William Shakespeare called public opinion the "mistress of success" and Blaise Pascal thought it was "the queen of
5032-410: A static photocell. The thallium sulfide (Thalofide) cell, developed by Theodore Case in the U.S., detected the light reflected from the subject and converted it into a proportional electrical signal. This was transmitted by AM radio waves to a receiver unit, where the video signal was applied to a neon light behind a second Nipkow disk rotating synchronized with the first. The brightness of the neon lamp
5180-467: A suitable influence for governments. In his 1672 essay On the Original and Nature of Government , William Temple gave an early formulation of the importance of public opinion. He observed that "when vast numbers of men submit their lives and fortunes absolutely to the will of one, it must be force of custom, or opinion which subjects power to authority". Temple disagreed with the prevalent opinion that
5328-464: A system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the " Braun tube" ( cathode-ray tube or "CRT") in the receiver. Moving images were not possible because, in the scanner: "the sensitivity was not enough and the selenium cell was very laggy". In 1921, Édouard Belin sent the first image via radio waves with his belinograph . By
5476-521: A television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED ), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s they were still CRT , it was only in early 2010s that flat screen TVs have started to overtake CRT TVs once and for all. Major manufacturers announced
5624-484: A television system using fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube. The problem of low sensitivity to light resulting in low electrical output from transmitting or "camera" tubes would be solved with the introduction of charge-storage technology by Kálmán Tihanyi beginning in 1924. His solution was a camera tube that accumulated and stored electrical charges ("photoelectrons") within
5772-510: A variety of academic studies investigating whether or not public opinion is influenced by " influentials ", or persons that have a significant effect on influencing opinion of the general public regarding any relevant issues. Many early studies have modeled the transfer of information from mass media sources to the general public as a "two-step" process. In this process, information from mass media and other far-reaching sources of information influences influentials, and influentials then influence
5920-485: A vital role in uncovering some critical decisions. Sentiment analysis or opinion mining is a method used to mine the thoughts or feelings of the general population. One of the struggles of public opinion is how it can be influenced by misinformation. The term "public opinion" was derived from the French opinion publique , which was first used in 1588 by Michel de Montaigne , one of the most significant philosophers of

According to Blumer, public opinion is discussed as a form of collective behavior (another specialized term) which is made up of those who are discussing a given public issue at any one time. Given this definition, there are many publics; each of them comes into being when an issue arises and ceases to exist when

In a 2015 study, it examined the role social constructions and policy implementation has on obesity while analyzing obesity narratives. Their findings suggest that social constructions of target populations do play an important role. Its role is to create an emotional response towards individuals in order to pushing implementation towards supportive policies and benefit positively constructed populations, while also pushing policies that punish

After World War II , an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion . In
8288-661: The 1920s, when amplification made television practical, Scottish inventor John Logie Baird employed the Nipkow disk in his prototype video systems. On 25 March 1925, Baird gave the first public demonstration of televised silhouette images in motion at Selfridges 's department store in London . Since human faces had inadequate contrast to show up on his primitive system, he televised a ventriloquist's dummy named "Stooky Bill," whose painted face had higher contrast, talking and moving. By 26 January 1926, he had demonstrated before members of

Social media platforms such as TikTok and YouTube recommend content that has the potential to spread misinformation due to the way their content algorithms are set up. Content that is more inflammatory tends to get sent out to users as it keeps them more engaged. This also allows extremist groups to coordinate and raise funds more easily. Public health issues have become areas of misinformation within

U.S. 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 1941. RCA, for example, used only Iconoscopes in the New York area, but Farnsworth Image Dissectors in Philadelphia and San Francisco. In September 1939, RCA agreed to pay

German social theorist Jürgen Habermas contributed the idea of public sphere to the discussion of public opinion. According to Habermas, the public sphere, or bourgeois public, is where "something approaching public opinion can be formed". Habermas claimed that the Public Sphere featured universal access, rational debate, and disregard for rank. However, he believes that these three features for how public opinion are best formed are no longer in place in western liberal democratic countries. Public opinion, in western democracy,
11100-404: The eve of the first episode's national premiere, the series was approved by the ABC for a second series. The second series was screened right after the first, beginning on 13 September 2008. The comedy-drama satire is produced by Working Dog Productions , which was also responsible for Frontline , The Panel , Thank God You're Here and Utopia . The music used during the opening credits
11248-421: The extra information in the signal and produce a limited-resolution color display. The higher-resolution black-and-white and lower-resolution color images combine in the brain to produce a seemingly high-resolution color image. The NTSC standard represented a significant technical achievement. The first color broadcast (the first episode of the live program The Marriage ) occurred on 8 July 1954. However, during
11396-472: The facsimile machine between 1843 and 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. Willoughby Smith discovered the photoconductivity of the element selenium in 1873. As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884 in Berlin . This was a spinning disk with a spiral pattern of holes, so each hole scanned
11544-402: The feedback of opinion and policy and use this phenomenon to explain the path dependency of institutions. For decades, the correlation between public opinion and public policy was consistently tested to examine its effects. A 1993 study argued that social construction is overlooked yet plays an important role when studying public policy. It tested the theory that social constructions influence
11692-440: The first outdoor remote broadcast of The Derby . In 1932, he demonstrated ultra-short wave television. Baird's mechanical system reached a peak of 240 lines of resolution on BBC telecasts in 1936, though the mechanical system did not scan the televised scene directly. Instead, a 17.5 mm film was shot, rapidly developed, and then scanned while the film was still wet. A U.S. inventor, Charles Francis Jenkins , also pioneered
11840-431: The following ten years, most network broadcasts and nearly all local programming continued to be black-and-white. It was not until the mid-1960s that color sets started selling in large numbers, due in part to the color transition of 1965, in which it was announced that over half of all network prime-time programming would be broadcast in color that fall. The first all-color prime-time season came just one year later. In 1972,
11988-441: The formation and dynamics of individuals' opinions. Much of this research draws on psychological research on attitudes . In communications studies and political science , mass media are often seen as influential forces on public opinion. Additionally, political socialization and behavioral genetics sometimes explain public opinion. The formation of public opinion starts with agenda setting by major media outlets throughout
12136-420: The foundation of policy implementation. Its conclusion the politically powerless and negatively perceived groups receive the least benefits in the policy process, showing that social constructions and social power do play an important role in the political policy implementation process. In a 2012 study, instead of analyzing public opinion and policy implementation, it analyzes how the public's participation plays
12284-477: The general public as opposed to the mass media directly influencing the public. While the "two-step" process regarding public opinion influence has motivated further research on the role of influential persons, a more recent study by Watts and Dodds (2007) suggests that while influentials play some role in influencing public opinion, "non-influential" persons that make up the general public are also just as likely (if not more likely) to influence opinion provided that
12432-436: The general public is composed of persons that are easily influenced. This is referred to in their work as the "Influential Hypothesis". The authors discuss such results by using a model to quantify the number of people influenced by both the general public and influentials. The model can be easily customized to represent a variety of ways that influencers interact with each other as well as the general public. In their study, such
12580-417: The iconoscope (or Emitron) produced an electronic signal and concluded that its real efficiency was only about 5% of the theoretical maximum. They solved this problem by developing and patenting in 1934 two new camera tubes dubbed super-Emitron and CPS Emitron . The super-Emitron was between ten and fifteen times more sensitive than the original Emitron and iconoscope tubes, and, in some cases, this ratio
12728-693: The industrial standard for public broadcasting in Europe from 1936 until 1960, when it was replaced by the vidicon and plumbicon tubes. Indeed, it represented the European tradition in electronic tubes competing against the American tradition represented by the image orthicon. The German company Heimann produced the Superikonoskop for the 1936 Berlin Olympic Games, later Heimann also produced and commercialized it from 1940 to 1955; finally
12876-437: The invention of the first working transistor at Bell Labs , Sony founder Masaru Ibuka predicted in 1952 that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets. The first fully transistorized, portable solid-state television set was the 8-inch Sony TV8-301 , developed in 1959 and released in 1960. This began the transformation of television viewership from
13024-411: The issue is resolved. Blumer claims that people participate in public in different capacities and to different degrees. So, public opinion polling cannot measure the public. An educated individual's participation is more important than that of a drunk. The "mass" in which people independently make decisions about, for example, which brand of toothpaste to buy, is a form of collective behavior different from
13172-401: The last holdout among daytime network programs converted to color, resulting in the first completely all-color network season. Early color sets were either floor-standing console models or tabletop versions nearly as bulky and heavy, so in practice they remained firmly anchored in one place. GE 's relatively compact and lightweight Porta-Color set was introduced in the spring of 1966. It used
13320-464: The last of these had converted to color. By the early 1980s, B&W sets had been pushed into niche markets, notably low-power uses, small portable sets, or for use as video monitor screens in lower-cost consumer equipment. By the late 1980s, even these last holdout niche B&W environments had inevitably shifted to color sets. Digital television (DTV) is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to
13468-544: The leader who was elected "will not deviate far from voters' opinion". A problem that arises when analyzing the data collected by researchers is how these issues that are "important" are selected when collecting the data about public opinion. It is hard to determine if there has been underdevelopment of certain issues. Another concern is how elites influence public opinion by persuasion and rhetoric, ultimately shaping policy-making. These two variables are ambiguous by nature and are hard to get to any conclusions, in most cases beyond
13616-413: The limits of research. Other variables to look at when analyzing the opinion-policy effect are the size of the majority public, election cycle time, degree of electoral competition, and the type of issue. For example, domestic affairs public opinion will be of greater importance than that of foreign affairs because of the complexity. Since presidents have the ability to influence their political agenda, it
13764-670: The mid-17th century. Although Charles II later tried to suppress the London coffeehouses as "places where the disaffected met, and spread scandalous reports concerning the conduct of His Majesty and his Ministers", the public flocked to them. For several decades following the Restoration, the Wits gathered round John Dryden at Will's Coffee House in Russell Street, Covent Garden. The coffee houses were great social levellers, open to all men and indifferent to social status, and as
13912-486: The mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The availability of various types of archival storage media such as Betamax and VHS tapes, LaserDiscs , high-capacity hard disk drives , CDs , DVDs , flash drives , high-definition HD DVDs and Blu-ray Discs , and cloud digital video recorders has enabled viewers to watch pre-recorded material—such as movies—at home on their own time schedule. For many reasons, especially
14060-476: The midst of a perfect storm of misinformation , where the wrong information or lack of it can be deadly." Cognitive psychologists such as Lewandowsky et al. have defined misinformation as "any piece of information that is initially processed as valid but is subsequently retracted or corrected." There are two common types of misinformation according to Hochschild , a political scientist . There are inactive informed and active misinformed . Inactive informed
14208-465: The minds of people. Since the 1950s, television has been the main medium for molding public opinion. Since the late 2000s, the Internet has become a platform for forming public opinion. Surveys have showed that more people get their news from social media and news websites as opposed to print newspapers. The accessibility of social media allows public opinion to be formed by a broader range of social movements and news sources. Gunn Enli identifies
14356-430: The nascent mind. Lastly, the persuasive power add more exertion in this regard . The most pervasive issue dividing theories of the opinion-policy relation bears a striking resemblance to the problem of monism - pluralism in the history of philosophy. The controversy deals with the question of whether the structure of socio-political action should be viewed as a more or less centralized process of acts and decisions by
14504-616: The negatively constructed populations. As with public policy, public opinion also has a close relationship with foreign policy . There is much debate concerning what the relationship is and the study of foreign policy's relationship with public opinion has evolved over time, with the Almond–Lippmann consensus being one of the first attempt to define this relationship. Published before the Vietnam War , Gabriel Almond and Walter Lippmann argued that public opinion about foreign policy
14652-408: The one hand, public opinion signals public preferences and potential voting behaviors to policymakers. This impact should be greater under more stable democratic institutions. It should be greatest in the realm of social policy because the public are highly motivated by potential goods and services they get from the state. On the other hand, social policy impacts public opinion. The goods and services
14800-466: The original Campbell-Swinton's selenium-coated plate. Although others had experimented with using a cathode-ray tube as a receiver, the concept of using one as a transmitter was novel. The first cathode-ray tube to use a hot cathode was developed by John B. Johnson (who gave his name to the term Johnson noise ) and Harry Weiner Weinhart of Western Electric , and became a commercial product in 1922. In 1926, Hungarian engineer Kálmán Tihanyi designed
14948-467: The parliamentary seat in Liverpool , a city with a growing and affluent middle class which he attributed to the growing influence of "public opinion". Jeremy Bentham was an impassioned advocate of the importance of public opinion in the shaping of constitutional governance. He thought it important that all government acts and decisions should be subject to the inspection of public opinion, because "to
15096-560: The pernicious exercise of the power of government it is the only check". He opined that public opinion had the power to ensure that rulers would rule for the greatest happiness of the greater number. He brought in Utilitarian philosophy in order to define theories of public opinion. The German sociologist Ferdinand Tönnies , by using the conceptional tools of his theory of Gemeinschaft and Gesellschaft , argued ( Kritik der öffentlichen Meinung , 1922), that 'public opinion' has
15244-456: The phosphors deposited on their outside faces instead of Baird's 3D patterning on a flat surface. The Penetron used three layers of phosphor on top of each other and increased the power of the beam to reach the upper layers when drawing those colors. The Chromatron used a set of focusing wires to select the colored phosphors arranged in vertical stripes on the tube. One of the great technical challenges of introducing color broadcast television
15392-457: The policy agenda, policy tools, and policy choices. Its conclusions states that social constructions help to understand the motive and decision making behind public officials who do implement certain policies towards target populations. In a 2004 study, they also take the approach of studying the relationship between social constructions and policy implementation. It tested the hypothesis that negative constructed social groups such as criminals are
15540-616: The possibility of a digital television signal. This breakthrough was of such significance that the FCC was persuaded to delay its decision on an ATV standard until a digitally-based standard could be developed. Public opinion In the 21st century, public opinion is widely thought to be heavily influenced by the media; many studies have been undertaken which look at the different factors which influence public opinion. Politicians and other people concerned with public opinion often attempt to influence it using advertising or rhetoric. Opinion plays
15688-507: The public at this time, viewing of the color field tests was restricted to RCA and CBS engineers and the invited press. The War Production Board halted the manufacture of television and radio equipment for civilian use from 22 April 1942 to 20 August 1945, limiting any opportunity to introduce color television to the general public. As early as 1940, Baird had started work on a fully electronic system he called Telechrome . Early Telechrome devices used two electron guns aimed at either side of
15836-427: The public gets via social policy builds normative expectations that shape public opinion. Furthermore, social policy constitutes the largest share of state spending budgets, making it an active and contentious political area. Together these theories suggest that causal effects are part of a feedback loop between opinion and policy. Using increasingly sophisticated methods, scholars are beginning to grasp and identify
15984-632: The public opinion field. According to the National Library of Medicine , "Misinformation can have negative effects in the real world, such as amplifying controversy about vaccines and propagating unproven cancer treatments." Medical misinformation has been relevant to changing public opinion in cases such as the HIV/AIDS epidemic . Originally, a myth was circulated that AIDS could be spread by touching people who were infected. This had implications for public opinion in regard to AIDS policies as
16132-428: The public's preference on salient matters like crime and economy. This reflects a populist type of democracy where the government portrays respect toward the people's views and they are connected. On the other hand, government institutions and elites believe the general populations' understanding of certain issued is limited, therefore they exercise autonomy when making these decisions. Baum and Kernell have stated that
16280-479: The public. Public opinion plays an important role in the political sphere. Cutting across all aspects of relationship between government and public opinion are studies of voting behavior. These have registered the distribution of opinions on a wide variety of issues, have explored the impact of special interest groups on election outcomes and have contributed to our knowledge about the effects of government propaganda and policy. Contemporary, quantitative approaches to
16428-512: The receiver, a type of Kerr cell modulated the light, and a series of differently angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image was transmitted "several times" each second. In 1911, Boris Rosing and his student Vladimir Zworykin created
16576-415: The reproducer) marked the start of the end for mechanical systems as the dominant form of television. Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the 1930s. The last mechanical telecasts ended in 1939 at stations run by a lot of public universities in the United States. In 1897, English physicist J. J. Thomson
16724-564: The resolution of the color information to conserve bandwidth. As black-and-white televisions could receive the same transmission and display it in black-and-white, the color system adopted is [backwards] "compatible." ("Compatible Color," featured in RCA advertisements of the period, is mentioned in the song " America ," of West Side Story , 1957.) The brightness image remained compatible with existing black-and-white television sets at slightly reduced resolution. In contrast, color televisions could decode
16872-558: The results of some "not very successful experiments" he had conducted with G. M. Minchin and J. C. M. Stanton. They had attempted to generate an electrical signal by projecting an image onto a selenium-coated metal plate that was simultaneously scanned by a cathode ray beam. These experiments were conducted before March 1914, when Minchin died, but they were later repeated by two different teams in 1937, by H. Miller and J. W. Strange from EMI , and by H. Iams and A. Rose from RCA . Both teams successfully transmitted "very faint" images with
17020-542: The right to read all the papers for and against the government", were the "seats of English liberty". Gentlemen's clubs proliferated in the 18th century, especially in the West End of London . Clubs took over the role occupied by coffee houses in 18th century London to some degree and reached the height of their influence in the late 19th century. Some notable names were White's , Brooks's , Arthur's and Boodle's which still exist today. These social changes, in which
17168-492: The show, and noted that senior public servants were not as innocent as they were portrayed. In contrast they found larger themes of media driven policies, "arse-covering" and superficial treatment of complex issues were "remarkably accurate", noting that the Melbourne 2am Lockout laws were a good example. Series 1 and 2 of The Hollowmen is available on DVD as a three disc box set. Television Television ( TV )
17316-449: The signal to individual television receivers. Alternatively, television signals are distributed by coaxial cable or optical fiber , satellite systems, and, since the 2000s, via the Internet. Until the early 2000s, these were transmitted as analog signals, but a transition to digital television was expected to be completed worldwide by the late 2010s. A standard television set consists of multiple internal electronic circuits , including
17464-595: The significance of the Bell Labs demonstration: "It was, in fact, the best demonstration of a mechanical television system ever made to this time. It would be several years before any other system could even begin to compare with it in picture quality." In 1928, WRGB , then W2XB, was started as the world's first television station. It broadcast from the General Electric facility in Schenectady, NY . It
17612-647: The spectrum of colors at the transmitting end and could not have worked as he described it. Another inventor, Hovannes Adamian , also experimented with color television as early as 1907. The first color television project is claimed by him, and was patented in Germany on 31 March 1908, patent No. 197183, then in Britain, on 1 April 1908, patent No. 7219, in France (patent No. 390326) and in Russia in 1910 (patent No. 17912). Scottish inventor John Logie Baird demonstrated
17760-419: The study of public opinion may be divided into four categories: The rapid spread of public opinion measurement around the world is reflection of the number of uses to which it can be put. Public opinion can be accurately obtained through survey sampling . Both private firms and governments use surveys to inform public policies and public relations. Numerous theories and substantial evidence exists to explain
17908-546: The system was improved further by eliminating a motor generator so that his television system had no mechanical parts. That year, Farnsworth transmitted the first live human images with his system, including a three and a half-inch image of his wife Elma ("Pem") with her eyes closed (possibly due to the bright lighting required). Meanwhile, Vladimir Zworykin also experimented with the cathode-ray tube to create and show images. While working for Westinghouse Electric in 1923, he began to develop an electronic camera tube. However, in
18056-641: The television. He published an article on "Motion Pictures by Wireless" in 1913, transmitted moving silhouette images for witnesses in December 1923, and on 13 June 1925, publicly demonstrated synchronized transmission of silhouette pictures. In 1925, Jenkins used the Nipkow disk and transmitted the silhouette image of a toy windmill in motion over a distance of 5 miles (8 km), from a naval radio station in Maryland to his laboratory in Washington, D.C., using
18204-493: The term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the first International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris. The anglicized version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires ". It
18352-577: The tube throughout each scanning cycle. The device was first described in a patent application he filed in Hungary in March 1926 for a television system he called "Radioskop". After further refinements included in a 1928 patent application, Tihanyi's patent was declared void in Great Britain in 1930, so he applied for patents in the United States. Although his breakthrough would be incorporated into
18500-439: The ultimate issue position. Public opinion about foreign policy is measured in the same way that all public opinion is measured. Through polls and surveys, respondents are asked about their issue positions. Conclusions are drawn by researchers by applying the scientific method . According to Robert Shapiro, public opinion and policy-making are fundamental to a democracy, which is linked to electoral accountability, meaning that
18648-522: The use of a CRT as a display device. The Braun tube became the foundation of 20th century television. In 1906 the Germans Max Dieckmann and Gustav Glage produced raster images for the first time in a CRT. In 1907, Russian scientist Boris Rosing used a CRT in the receiving end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen. In 1908, Alan Archibald Campbell-Swinton ,
18796-494: The widespread adoption of television. On 7 September 1927, U.S. inventor Philo Farnsworth 's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. By 3 September 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press. This is widely regarded as the first electronic television demonstration. In 1929,
18944-430: The work of Nipkow and others. However, it was not until 1907 that developments in amplification tube technology by Lee de Forest and Arthur Korn , among others, made the design practical. The first demonstration of the live transmission of images was by Georges Rignoux and A. Fournier in Paris in 1909. A matrix of 64 selenium cells, individually wired to a mechanical commutator , served as an electronic retina . In
19092-496: The world". In his treatise, An Essay Concerning Human Understanding c, John Locke considered that man was subject to three laws: the divine law , the civil law and most importantly in Locke's judgement, the law of opinion or reputation . He regarded the latter as of the highest importance because dislike and ill opinion force people to conform in their behaviour to social norms, however he did not consider public opinion as
19240-457: The world's first color transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color, and three light sources at the receiving end, with a commutator to alternate their illumination. Baird also made the world's first color broadcast on 4 February 1938, sending a mechanically scanned 120-line image from Baird's Crystal Palace studios to
19388-549: The world's first public demonstration of an all-electronic television system, using a live camera, at the Franklin Institute of Philadelphia on 25 August 1934 and for ten days afterward. Mexican inventor Guillermo González Camarena also played an important role in early television. His experiments with television (known as telectroescopía at first) began in 1931 and led to a patent for the "trichromatic field sequential system" color television in 1940. In Britain,
19536-399: The world. This agenda setting dictates what is newsworthy and how and when it will be reported. The media agenda is set by a variety of different environmental and newswork factors that determines which stories will be newsworthy. Another key component in the formation of public opinion is framing . Framing is when a story or piece of news is portrayed in a particular way and is meant to sway
19684-408: Was "...formed in English or borrowed from French télévision ." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904)." The abbreviation TV is from 1948. The use of the term to mean "a television set " dates from 1941. The use of the term to mean "television as
19832-459: Was able, in his three well-known experiments, to deflect cathode rays, a fundamental function of the modern cathode-ray tube (CRT). The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the "Braun" tube. It was a cold-cathode diode , a modification of the Crookes tube , with a phosphor -coated screen. Braun was the first to conceive
19980-518: Was considerably greater. It was used for outside broadcasting by the BBC, for the first time, on Armistice Day 1937, when the general public could watch on a television set as the King laid a wreath at the Cenotaph. This was the first time that anyone had broadcast a live street scene from cameras installed on the roof of neighboring buildings because neither Farnsworth nor RCA would do the same until
20128-654: Was designed in the Soviet Union in 1944 and became a national standard in 1946. The first broadcast in 625-line standard occurred in Moscow in 1948. The concept of 625 lines per frame was subsequently implemented in the European CCIR standard. In 1936, Kálmán Tihanyi described the principle of plasma display , the first flat-panel display system. Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes . Following
20276-411: Was more reliable and visibly superior. This was the world's first regular "high-definition" television service. The original U.S. iconoscope was noisy, had a high ratio of interference to signal, and ultimately gave disappointing results, especially compared to the high-definition mechanical scanning systems that became available. The EMI team, under the supervision of Isaac Shoenberg , analyzed how
20424-408: Was not until the 1990s that digital television became possible. Digital television was previously not practically possible due to the impractically high bandwidth requirements of uncompressed digital video , requiring around 200 Mbit/s for a standard-definition television (SDTV) signal, and over 1 Gbit/s for high-definition television (HDTV). A digital television service
20572-410: Was one by Maurice Le Blanc in 1880 for a color system, including the first mentions in television literature of line and frame scanning. Polish inventor Jan Szczepanik patented a color television system in 1897, using a selenium photoelectric cell at the transmitter and an electromagnet controlling an oscillating mirror and a moving prism at the receiver. But his system contained no means of analyzing
20720-855: Was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1,200 rpm and a similar disc spinning in synchronization in front of the cathode-ray tube inside the receiver set. The system was first demonstrated to the Federal Communications Commission (FCC) on 29 August 1940 and shown to the press on 4 September. CBS began experimental color field tests using film as early as 28 August 1940 and live cameras by 12 November. NBC (owned by RCA) made its first field test of color television on 20 February 1941. CBS began daily color field tests on 1 June 1941. These color systems were not compatible with existing black-and-white television sets , and, as no color television sets were available to
20868-524: Was popularly known as " WGY Television." Meanwhile, in the Soviet Union , Leon Theremin had been developing a mirror drum-based television, starting with 16 lines resolution in 1925, then 32 lines, and eventually 64 using interlacing in 1926. As part of his thesis, on 7 May 1926, he electrically transmitted and then projected near-simultaneous moving images on a 5-square-foot (0.46 m ) screen. By 1927 Theremin had achieved an image of 100 lines,
21016-517: Was proposed in 1986 by Nippon Telegraph and Telephone (NTT) and the Ministry of Posts and Telecommunication (MPT) in Japan, where there were plans to develop an "Integrated Network System" service. However, it was not possible to implement such a digital television service practically until the adoption of DCT video compression technology made it possible in the early 1990s. In the mid-1980s, as Japanese consumer electronics firms forged ahead with
21164-407: Was removed from schedule due to the 2008 Beijing Olympics . The season finale aired at 9:00 pm on Wednesday 27 August. It was partially inspired by Cilauro's 1996 documentary The Campaign about Paul Keating's failed election. They initially wanted to make a series about an independent politician, but decided that such people didn't really hold much power and wanted to explore the idea that politics
21312-416: Was replaced by secular literature, novels and pamphlets. In parallel to this was the growth in reading societies and clubs. At the turn of the century the first circulating library opened in London and the public library became widespread and available to the public. An institution of central importance in the development of public opinion, was the coffee-house , which became widespread throughout Europe in
21460-515: Was the desire to conserve bandwidth , potentially three times that of the existing black-and-white standards, and not use an excessive amount of radio spectrum . In the United States, after considerable research, the National Television Systems Committee approved an all-electronic system developed by RCA , which encoded the color information separately from the brightness information and significantly reduced
21608-500: Was unable or unwilling to introduce evidence of a working model of his tube that was based on his 1923 patent application. In September 1939, after losing an appeal in the courts and being determined to go forward with the commercial manufacturing of television equipment, RCA agreed to pay Farnsworth US$ 1 million over ten years, in addition to license payments, to use his patents. In 1933, RCA introduced an improved camera tube that relied on Tihanyi's charge storage principle. Called
21756-671: Was unstructured, incoherent, and highly volatile, and that public opinion shouldn't influence foreign policy. More recent studies have rebuked the Almond-Lippmann Consensus, showing how people's opinions are generally stable, and that while individuals may not be entirely informed about every issue, they still act efficiently and rationally. People's judgments about issues are often based on heuristics, which are mental shortcuts that allow rational decisions to be made quickly. Heuristics apply to public opinion about domestic as well as foreign policy. The deductive heuristic
