Mass media
Mass media denotes a section of the media specifically designed to reach a large audience. The term was coined in the 1920s with the advent of nationwide radio networks, mass-circulation newspapers and magazines. However, some forms of mass media such as books and manuscripts had already been in use for centuries.
Mass media includes Internet media (like blogs, message boards, podcasts, and video sharing) because individuals now have a means to exposure that is comparable in scale to that previously restricted to a select group of mass media producers. The communications audience has been viewed by some commentators as forming a mass society with special characteristics, notably atomization or lack of social connections, which render it especially susceptible to the influence of modern mass-media techniques such as advertising and propaganda.
The term public media is less used and is defined as "media whose mission is to serve or engage a public."[1]
Marshall McLuhan, one of the biggest critics in media's history, brought up the idea that "the medium is the message".
History
Types of drama in numerous cultures were probably the first mass-media, going back into the Ancient World.
The first dated printed book known is the "Diamond Sutra", printed in China in 868 AD, although it is clear that books were printed earlier. Movable clay type was invented in 1041 in China. However, due to the slow spread of literacy to the masses in China, and the relatively high cost of paper there, the earliest printed mass-medium was probably European popular prints from about 1400. Although these were produced in huge numbers, very few early examples survive, and even most known to be printed before about 1600 have not survived. Johannes Gutenberg printed the first book on a printing press with movable type in 1453. This invention transformed the way the world received printed materials, although books remained too expensive really to be called a mass-medium for at least a century after that.
Newspapers developed from about 1612, with the first example in English in 1620;[2] but they took until the 19th century to reach a mass-audience directly.
During the 20th century, the growth of mass media was driven by technology, including that which allowed much duplication of material. Physical duplication technologies such as printing, record pressing and film duplication allowed the duplication of books, newspapers and movies at low prices to huge audiences. Radio and television allowed the electronic duplication of information for the first time.
Mass media had the economics of linear replication: a single work could make money. An example of Riel and Neil's theory. proportional to the number of copies sold, and as volumes went up, unit costs went down, increasing profit margins further. Vast fortunes were to be made in mass media.
In a democratic society, the media can serve the electorate about issues regarding government and corporate entities (see Media influence).
Some consider the concentration of media ownership to be a threat to democracy.[3]
Purposes
Mass media can be used for various purposes:
Advocacy, both for business and social concerns. This can include advertising, marketing, propaganda, public relations, and political communication.
Entertainment, traditionally through performances of acting, music, and sports, along with light reading; since the late 20th century also through video and computer games.
Public service announcements.
Journalism
Journalism is the discipline of collecting, analyzing, verifying and presenting information regarding current events, trends, issues and people. Those who practice journalism are known as journalists.
News-oriented journalism is sometimes described as the "first rough draft of history" (attributed to Phil Graham), because journalists often record important events, producing news articles on short deadlines. While under pressure to be first with their stories, news media organizations usually edit and proofread their reports prior to publication, adhering to each organization's standards of accuracy, quality and style. Many news organizations claim proud traditions of holding government officials and institutions accountable to the public, while media critics have raised questions about holding the press itself accountable.
Public relations
Public relations is the art and science of managing communication between an organization and its key publics to build, manage and sustain its positive image. Examples include:
Corporations use marketing public relations to convey information about the products they manufacture or services they provide to potential customers to support their direct sales efforts. Typically, they support sales in the short and long term, establishing and burnishing the corporation's branding for a strong, ongoing market.
Corporations also use public relations as a vehicle to reach legislators and other politicians, seeking favorable tax, regulatory, and other treatment, and they may use public relations to portray themselves as enlightened employers, in support of human-resources recruiting programs.
Nonprofit organizations, including schools and universities, hospitals, and human and social service agencies, use public relations in support of awareness programs, fund-raising programs, staff recruiting, and to increase patronage of their services.
Politicians use public relations to attract votes and raise money, and, when successful at the ballot box, to promote and defend their service in office, with an eye to the next election or, at career’s end, to their legacy.
Forms
Electronic media and print media include:
Broadcasting, in the narrow sense, for radio and television.
Many instances of various types of recorded discs or tapes. In the 20th century, these were mainly used for music. Video and computer uses followed.
Film, most often used for entertainment, but also for documentaries.
The Internet, which has many uses and presents both opportunities and challenges. Examples can include Blogs and podcasts (such as news, music, pre-recorded speech, and video)
Mobile phones, which can be used for rapid breaking news and short clips of entertainment like jokes, horoscopes, alerts, games, music, and advertising
Publishing, including electronic publishing
Video games, which have developed into a mass form of media since cutting-edge devices such as the PlayStation 3, XBox 360, and Wii broadened their use.
Audio recording and reproduction
Sound recording and reproduction is the electrical or mechanical re-creation and/or amplification of sound, often as music. This involves the use of audio equipment such as microphones, recording devices and loudspeakers. From early beginnings with the invention of the phonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the 78 record, the magnetic wire recorder followed by the tape recorder, the vinyl LP record. The invention of the compact cassette in the 1960s, followed by Sony's Walkman, gave a major boost to the mass distribution of music recordings, and the invention of digital recording and the compact disc in 1983 brought massive improvements in ruggedness and quality. The most recent developments have been in digital audio players.
An album is a collection of related audio recordings, released together to the public, usually commercially.
The term record album originated from the fact that 78 RPM Phonograph disc records were kept together in a book resembling a photo album. The first collection of records to be called an "album" was Tchaikovsky's Nutcracker Suite, release in April 1909 as a four-disc set by Odeon records.[4][5] It retailed for 16 shillings — about £15 in modern currency.
A music video (also promo) is a short film or video that accompanies a complete piece of music, most commonly a song. Modern music videos were primarily made and used as a marketing device intended to promote the sale of music recordings. Although the origins of music videos go back much further, they came into their own in the 1980s, when Music Television's format was based on them. In the 1980s, the term "rock video" was often used to describe this form of entertainment, although the term has fallen into disuse.
Music videos can accommodate all styles of filmmaking, including animation, live action films, documentaries, and non-narrative, abstract film.
Broadcast
The sequencing of content in a broadcast is called a schedule. With all technological endeavours a number of technical terms and slang are developed please see the list of broadcasting terms for a glossary of terms used.
Television and radio programs are distributed through radio broadcasting over frequency bands that are highly regulated by the Federal Communications Commission. Such regulation includes determination of the width of the bands, range, licencing, types of receivers and transmitters used, and acceptable content.
Cable programs are often broadcast simultaneously with radio and television programs, but have a more limited audience. By coding signals and having decoding equipment in homes, cable also enables subscription-based channels and pay-per-view services.
A broadcasting organisation may broadcast several programs at the same time, through several channels (frequencies), for example BBC One and Two. On the other hand, two or more organisations may share a channel and each use it during a fixed part of the day. Digital radio and digital television may also transmit multiplexed programming, with several channels compressed into one ensemble.
When broadcasting is done via the Internet the term webcasting is often used. In 2004 a new phenomenon occurred when a number of technologies combined to produce podcasting. Podcasting is an asynchronous broadcast/narrowcast medium, with one of the main proponents being Adam Curry and his associates the Podshow.
