Media influence or media effects are used in media studies, psychology, communication theory and sociology to refer to the theories about the ways in which mass media and media culture affect how their audiences think and behave.
The agenda-setting process is arguably an unavoidable part of news gathering by the large organizations which make up much of the mass media. (Just four main news agencies — AP, UPI, Reuters and Agence-France-Presse — claim together to provide 90% of the total news output of the world’s press, radio and television). According to Stuart Hall, because some of the media produce material which often is impartial and serious, they are accorded a high degree of respect and authority. However, in practice the ethics of the press and television are closely related to that of the hegemonic establishment, providing vital support to the existing order. Therefore, he says, independence is not “a mere cover, it is central to the way power and ideology are mediated in societies like ours.”
The public is bribed with popular radio, television and newspapers into an acceptance of the biased, the misleading, and the status quo. The media are not, according to this approach, crude agents of propaganda. They organize public understanding. However, the overall interpretations they provide in the long run are those most preferred by, and least challenging to, those with economic power. Greg Philo demonstrates this in his 1991 article, “Seeing is Believing”, in which he showed that recollections of the 1984 UK miners’ strike were strongly correlated with the media presentation of the event, including the perception of the picketing as largely violent when violence was rare, and the use by the public of phrases which had appeared originally in the media.
McCombs and Shaw (1972) demonstrate the agenda-setting effect at work in a study conducted in Chapel Hill, North Carolina, USA during the 1968 presidential elections. A representative sample of un-decided voters was asked to outline the key issues of the election as it perceived them. Concurrently, the mass media serving these subjects were collected and their content was analyzed. The results showed a definite correlation between the two accounts of predominant issues. "The evidence in this study that voters tend to share the media's composite definition of what is important strongly suggests an agenda-setting function of the mass media." (McCombs and Shaw).
New media 
Theorists such as Louis Wirth and Talcott Parsons have emphasized the importance of mass media as instruments of social control. In the 21st century, with the rise of the internet, the two-way relationship between mass media and public opinion is beginning to change, with the advent of new technologies such as blogging.
Mander’s theory is related to Jean Baudrillard’s concept of ‘hyperreality’. We can take the 1994 O.J. Simpson trial as an example, where the reality reported on was merely the catalyst for the simulacra (images) created, which defined the trial as a global event and made the trial more than it was. Essentially, hyperreality is the concept that the media are not merely a window on to the world (as if a visiting alien were watching television), but are part of the reality they describe. Hence (although additionally there is the question of navel-gazing) the media’s obsession with media-created events.
It is this which led Marshall McLuhan in the 1960s to say that "the medium is the message", and to suggest that mass media are increasingly creating a "global village". For example, there is evidence that Western media influence in Asia is the driving force behind rapid social change: “it is as if the 1960s and the 1990s were compressed together.” A notable example is the recent introduction of television to Bhutan, resulting in rapid Westernization. This raises questions of ‘cultural imperialism’ (Schiller) — the de facto imposition, through economic and political power and through the media, of Western (and in particular US) culture.
Social scientists have made efforts to integrate the study of the mass media as an instrument of control into the study of political and economic developments in the Afro-Asian countries. David Lerner (1958) has emphasized the general pattern of increase in standard of living, urbanization, literacy and exposure to mass media during the transition from traditional to modern society. According to Lerner, while there is a heavy emphasis on the expansion of mass media in developing societies, the penetration of a central authority into the daily consciousness of the mass has to overcome profound resistance.
Government and Mass Media 
They include licensing in advance; censorship of offending material before publication; seizure of offending material; injunctions against publication of a newspaper or book or of specified content; requirement of surety bonds against libel or other offense; compulsory disclosure of ownership and authority; post publication criminal penalties for objectionable matter; post publication collection of damages in a civil action; post publication correction of libel and other misstatements; discrimination in granting access to news source and facilities; discrimination and denial in the use of communications facilities for distribution; taxes; discriminatory subsidies; and interference with buying, reading and listening.
Mass Media in a free enterprise capitalist society 
Although a sizable portion of mass media offerings – particularly news, commentaries, documentaries, and other informational programmes – deal with highly controversial subjects, the major portion of mass media offerings are designed to serve an entertainment function. These programmes tend to avoid controversial issues and reflect beliefs and values sanctified by mass audience. This course is followed by Television networks, whose investment and production costs are high. Jerry Mander’s work has highlighted this particular outlook. According to him, the atomized individuals of mass society lose their souls to the phantom delights of the film, the soap opera, and the variety show. They fall into a stupor, or apathetic hypnosis, that Lazarsfeld called the ‘narcotizing dysfunction’ of exposure to mass media.
Individuals become ‘irrational victims of false wants’ – the wants which corporations have thrust upon them, and continue to thrust upon them, through both the advertising in the media (with its continual exhortation to consume) and through the individualist consumption culture it promulgates. Thus, according to the Frankfurt School, leisure has been industrialized. The production of culture had become standardized and dominated by the profit motive as in other industries. In a mass society leisure is constantly used to induce the appropriate values and motives in the public. The modern media train the young for consumption. ‘Leisure had ceased to be the opposite of work, and had become a preparation for it.’
Mass media, mass culture and elite 
The relation of the mass media to contemporary popular culture is commonly conceived in terms of dissemination from the elite to the mass. The concentration of ownership and media control has led to accusations of a 'media elite' having a form of 'cultural dictatorship'. Thus the continuing debate about the influence of 'media barons' such as Conrad Black and Rupert Murdoch. For example, the UK Observer (March 1, 1998) reported that the Murdoch-owned HarperCollins' decision not to publish Chris Patten's East and West, might have been taken to protect Murdoch's Chinese broadcasting interests (East and West describes the Chinese leadership as "faceless Stalinists"). In this case, the author was able to have the book accepted by another publisher. Related, but more insidious, is self-censorship by members of the media in the interests of the owner.
Media effects on nutrition 
||An editor has expressed a concern that this section lends undue weight to certain ideas relative to the article as a whole. Please help to discuss and resolve the dispute before removing this message. (December 2012)|
Mass media has been supported by the nutrition field, to direct the public’s nutrition-related behaviors to healthier ways. Various social marketing campaigns and advertising campaigns have been proved to be effective in changing people’s knowledge, attitudes, as well as behaviors related to nutrition.
Most of these programs require substantial financial support. Research demonstrates that to include nutrition or health-related messages in entertainment programs on mass media will be cost-effective and promising. Research done by Valente, from the University of Southern California. After consultation with a CDC expert, the scriptwriter of the popular medical show ER (Emergency Room) came up with a storyline of an obese low-income Africa American teenager boy who had been diagnosed with hypertension during his visit to the emergency room. The storyline covered three episodes of ER, and discussed hypertension, obese, heart disease, 5 A Day (a nutrition concept which encourages people to consume five portions of fruits and vegetables each day), healthy eating habits, and life style. Valente examined people’s health/nutrition-related knowledge, attitudes, and behavior before and after the air of the three episodes of ER. And the results showed that, this minor storyline on ER about teen obesity, hypertension, and 5 A Day led to modest positive impacts on people’s knowledge, attitudes, and practices. In general, after watching those 3 episodes of ER, people gained higher awareness and knowledge of 5 A Day, and were reported to engage in some self-reported health behaviors. Since the cost of this intervention can be considered minimal, the modest changes in people indicate the cost-effectiveness of this particular intervention. This research does provide a new insight into the effects of mass media, especially mass entertainment programs, on the public, and high light the promising future of the cost-effective mass media/entertainment program intervention on people’s knowledge, attitudes, as well as behaviors related to nutrition/health field.
On average, children in the United States view 15 television food advertisements every day, 98% of which are low in nutritional value, averaging out to 5,500 messages per year. Studies have found that recognizable labels test better with the public. One experiment done found that people gave better reviews to Coke from a cup with a Coke logo than they gave to coke served in a plain cup. A similar study conducted found that preschoolers liked the taste of foods and beverages significantly more when they were placed in McDonald’s packaging compared to the same foods in plain packaging.
Media-influenced violence 
Various studies indicate that media affects public opinion.
In 2008, The Lancet published a study indicating that North American young boys were negatively influenced by portrayals of violence on television. This often resulted in short term fearful or aggressive behavior.
In 2006, an Associated Press article reported the negative affects on self-image of both men and women, the result of the use of unrealistic models in advertising. However, this is a contentious issue.
To explain the problem of violence in society, researchers should begin with that social violence and seek to explain it with reference, quite obviously, to those who engage in it: their identity, background, character and so on.
David Gauntlett goes on to criticize studies that focus on children by stating that they do not have a control group, and that the studies are conducted primarily to further a "barely-concealed conservative ideology." He counters the premise of these studies with the concept that not all depictions of violence are even bad to witness. USC Professor Henry Jenkins, for instance, suggested in his speech to congress that The Basketball Diaries utilizes violence in a form of social commentary that provides clear social benefit.
Gauntlett explains further that objects defined as "violent" or "anti-social" may not be judged as such in the minds of the viewer and tend to be viewed in artificial circumstances. These objects are furthermore based on previous studies with flawed methodology, and are not grounded in theory. Additionally, he claims that the effects model attempts to understand the meanings of media.
- Historical criticisms situate the 'meta-narrative' of effects theory within a long history of distrust of new forms of media, dating as far back as Socrates's objections to the deleterious effects due to the written alphabet.
- Political criticisms pose an alternative conception of humans as rational, critical subjects who are alert to genre norms and adept at interpreting and critiquing media representations, instead of passively absorbing them.
Supporters of effects theory contend that commercials and advertising prove that media influence behavior. In the 20th century, aggressive media attention and negative coverage of trials involving celebrities like Roscoe Fatty Arbuckle or Michael Jackson have influenced the general public's opinion, before the trials effectively started. However, these critics do point out that while the media could have an effect on people's behavior this isn't necessarily always the case.
Critics of the media effects theory point out that many copycat murders, suicides and other violent acts nearly always happen in abnormal upbringings. Violent, emotionally neglectful or aggressive environments influence behavior more than watching certain programs, films or listening to certain music. Most people who carry out these acts are also mentally unstable to begin with.
Also there are other thinkers who criticize effects based research, such as Terry Flew and Sal Humphrey, Barker and Freedman.,-Martin Barker (2001) criticised Elizabeth Newson who alleged link between media violence and real life violence in her report in 1994, Brooke (2003–07),for example talks about this in details. The report gained media attention when it claimed the horror film Child's Play 3 had influenced two 10-year-old boys' behavior and led to the Murder of James Bulger in Feb. 1993. After examining and assessing Newson’s report, it was apparent that there was no clear link between the film and the crime. Critics pointed out that Newson's case studies were reliant on press accounts and opinions rather than independent research. However, Newson's report was influential, and has led to more censorship of videos and more concern from the British Board of Film classification on the psychological effects of media violence. The attention and question become whether they were watching violent media.
But Barker (2001) doesn’t agree with Elizabeth Newson. He rejected her claim about the connection between media violence and real life violence, in his argument he justifies his position, he indicates that there was not a scrap of evidence that the boys had seen the movie and Child's Play 3 is a moral film. He also criticized anti media campaigns and described them as ignorant and disguised political campaigns. He states that these claims are represented by media and most of people have no chance to check the credibility of them, he also points out that these films including Child's Play 3 are often attacked because they deal with political issues. Moreover, he lists real cases, for example “a man takes a gun and shoots his entire family after watching the news, arrested and tried, he explains his actions on the basis that the world news was so bad there seemed no point in anyone going on living”. Barker suggests that this case for example is no different that other putative cases of media a causing violence, Barker said that we should not always blindly blame the media because people are not copycats, instead we should be aware of someone's mental state and take other factors into account before making such claims. For example, in his case he states that the man's reaction was abnormal. Therefore, his behavior could not be explained by suggesting “the effects of the news”. There are other social and cultural factors in criminal acts in which the media are not the basic influence. Barker also suggests 'that we must look beyond a specific film to think about the specific context in which it has been consumed, and the wider social background of the people'., according to Barker there is no such thing called violence in the media that either could or could not cause violence, we should rather pay attention to how social factors and background make some people consume media in specific way., for instance, even the news also show lots of violence, so people should rather pay attention to how social factors and background make some people consume media in particular way. In addition Barker (2001) proposes further research, he suggests that the theory of media violence connection must be tested because identification with particular element in a film is not something can be seen. He also noted problem with campaigners treating delinquents as normal people who become influenced by the media. Therefore, he suggests further research on how these people understand and consume media.
-Critics of effects research see no connection between exposure to media violence and real life violence. Although some research claims that heavy exposure to media violence can lead to more aggressive behavior, it has been suggested that exposure alone does not cause a child to commit crimes.
-Flew and Humphreys (2005) said that the assumptions of effects researchers are frequently flawed. According to Flew and Humphreys, Freedman (2001) and Goldstein (2001) the number of studies on games and violence is small and the research suffers from flawed methodologies which do very little to prove a direct link. Terry Flew and Sal Humphreys also state ‘that differing context of consumption will always mean we need to take account of the particularities of players and how and why they play, effects researches often give insufficient account to the relevance of cultural contexts and the way in which media are actually implicated in the circulation of meanings in our cultures'.
-Freedman (2007) is another thinker who rejects this idea, in reference to the FCC ‘the Federal Communications Commission in US’ report that suggests link between media violence and real life violence, Freedman indicates the lack of discussion and states that the FCC does not make a sufficiviolence. For example a recent long-term outcome study of youth found no long-term relationship between watching violent television and youth violence or bullying
Certain groups tend to argue for media effects in an effort to promote a political cause. Demands for the banning of certain songs or the labeling of obscene albums came specifically from conservative political groups in the United States. However, Tipper Gore, the wife of Al Gore, was the founder of the Parents Music Resource Center, and was the main figure in pushing for warning labels on music although she does not fit into the conservative demographic. They argued that such material had simple and identifiable effects on children, and thus should be banned/labelled. Political factions use the media to influence possible members into joining their groups. ent distinction between people’s opinions, intuitions and musings on the one hand, and the hard scientific data on the other, and he indicates the lack of discussion of one of the strongest arguments against the idea that media violence causes aggression. According to Freedman the rate of violent crime in the United states increased sharply from 1965 to 1980 and some people blamed that increase on media. The rate of violent crime leveled off until about 1992, since that time, television continued to have violent programs, there was also more scenes and media showing more violence, if exposure to violent media cause real violence one would surely expect the rate of violent crime to have increased sharply, yet, since 1992 there has been a dramatic drop in violent crime, it seems clear that media violence did not cause the earlier increase. Therefore, it is widely accepted that there is no convincing evidence that prove that media violence cause violent crime or any type of real life
