Introduction With the popularity and interactivity offered by the Internet and World Wide Web, media organizations see the Web as a medium they must conquer if they are going to survive Villano, They have good reason to be concerned. From an historical perspective, whenever a new medium reaches critical mass it threatens to, and does, displace existing media to some degree.
Radio broadcasting and Television The sequencing of content in a broadcast is called a schedule. With all technological endeavours a number of technical terms and slang have developed. Please see the list of broadcasting terms for a glossary of terms used. Radio and television programs are distributed over frequency bands that in the United States are highly regulated.
Such regulation includes determination of the width of the bands, range, licensing, types of receivers and transmitters used, and acceptable content. Cable television programs are often broadcast simultaneously with radio and television programs, but have a more limited audience.
A broadcasting organisation may broadcast several programs simultaneously, through several channels frequenciesfor example BBC One and Two. Digital radio and digital television may also transmit multiplexed programming, with several channels compressed into one ensemble.

Adam Curry and his associates, the Podshoware principal proponents of podcasting. The name comes from the photographic film also called filmstockhistorically the primary medium for recording and displaying motion pictures.
Many other terms for film exist, such as motion pictures or just pictures and "picture"the silver screen, photoplays, the cinema, picture shows, flicks, and most common, movies.
Films are produced by recording people and objects with camerasor by creating them using animation techniques or special effects.

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 term "computer game" also includes games which display only text and which can, therefore, theoretically be played on a teletypewriter or which use other methods, such as sound or vibration, as their primary feedback device, but there are very few new games in these categories.
Also, more esoteric devices have been used for input, e. Usually there are rules and goals, but in more open-ended games the player may be free to do whatever they like within the confines of the virtual universe. In common usage, an " arcade game " refers to a game designed to be played in an establishment in which patrons pay to play on a per-use basis.
A "computer game" or " PC game " refers to a game that is played on a personal computer. A " Console game " refers to one that is played on a device specifically designed for the use of such, while interfacing with a standard television set.Defining & Working With 21st Century Mass Media by Anthony S.
