The Internet (also known simply as "the Net" or less precisely as "the Web") is a more interactive medium of mass media, and can be briefly described as "a network of networks". Specifically, it is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It consists of millions of smaller domestic, academic, business, and governmental networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.
Contrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is the system of interconnectedcomputer networks, linked by copper wires, fiber-optic cables, wireless connections etc.; the Web is the contents, or the interconnecteddocuments, linked by hyperlinks and URLs. The World Wide Web is accessible through the Internet, along with many other services including e-mail, file sharing and others described below.
Toward the end of the 20th century, the advent of the World Wide Web marked the first era in which most individuals could have a means of exposure on a scale comparable to that of mass media. Anyone with a web site has the potential to address a global audience, although serving to high levels of web traffic is still relatively expensive. It is possible that the rise of peer-to-peer technologies may have begun the process of making the cost of bandwidth manageable. Although a vast amount of information, imagery, and commentary (i.e. "content") has been made available, it is often difficult to determine the authenticity and reliability of information contained in web pages (in many cases, self-published). The invention of the Internet has also allowed breaking news stories to reach around the globe within minutes. This rapid growth of instantaneous, decentralized communication is often deemed likely to change mass media and its relationship to society.
"Cross-media" means the idea of distributing the same message through different media channels. A similar idea is expressed in the news industry as "convergence". Many authors understand cross-media publishing to be the ability to publish in both print and on the web without manual conversion effort. An increasing number of wireless devices with mutually incompatible data and screen formats make it even more difficult to achieve the objective “create once, publish many”.
The internet is quickly becoming the center of mass media. Everything is becoming accessible via the internet. Instead of picking up a newspaper, or watching the 10 o'clock news, people will log onto the internet to get the news they want, when they want it. Many workers listen to the radio through the internet while sitting at their desk. Games are played through the internet.
The Internet and Education: Findings of the Pew Internet & American Life Project Even the education system relies on the internet. Teachers can contact the entire class by sending one e-mail. They have web pages where students can get another copy of the class outline or assignments. Some classes even have class blogs where students must post weekly, and are graded on their contributions. The internet thus far has become an extremely dominant form of media.
'Film' encompasses motion pictures as individual projects, as well as the field in general. The name comes from the photographic film (also called filmstock), historically the primary medium for recording and displaying motion pictures. Many other terms exist — motion pictures (or just pictures and "picture"), the silver screen, photoplays, the cinema, picture shows, flicks — and commonly movies.
Films are produced by recording people and objects with cameras, or by creating them using animation techniques and/or special effects. They comprise a series of individual frames, but when these images are shown rapidly in succession, the illusion of motion is given to the viewer. Flickering between frames is not seen due to an effect known as persistence of vision — whereby the eye retains a visual image for a fraction of a second after the source has been removed. Also of relevance is what causes the perception of motion; a psychological effect identified as beta movement.
Film is considered by many to be an important art form; films entertain, educate, enlighten and inspire audiences. Any film can become a worldwide attraction, especially with the addition of dubbing or subtitles that translate the film message. Films are also artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them.
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 radioand 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.
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 thephonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the78 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 thecompact 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 byOdeon records. 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.
