Communications media

In communication, media is the storage and transmission tools used to store and deliver information or data. It is often referred to as synonymous with mass media or news media, but may refer to a single medium used to communicate any data for any purpose.

Evolution
The beginning of human communication through artificial channels, i.e. not vocalization or gestures, goes back to ancient cave paintings, drawn maps, and writing.

Our indebtedness to the Ancient Romans in the field of communication does not end with the Latin root "communicare". They devised what might be described as the first real mail or postal system in order to centralize control of the empire from Rome. This allowed for personal letters and for Rome to gather knowledge about events in its many widespread provinces.

The adoption of a dominant communication medium is important enough that historians have folded civilization into "ages" according to the medium most widely used. A book titled "Five Epochs of Civilization" by William McGaughey (Thistlerose, 2000) divides history into the following stages: Ideographic writing produced the first civilization; alphabetic writing, the second; printing, the third; electronic recording and broadcasting, the fourth; and computer communication, the fifth. The media affects what people think about themselves and how they perceive people as well. What we think about self image and what others should look like comes from the media.

While it could be argued that these "Epochs" are just a historian's construction, digital and computer communication shows concrete evidence of changing the way humans organize. The latest trend in communication, termed smartmobbing, involves ad-hoc organization through mobile devices, allowing for effective many-to-many communication and social networking.

Electronic media
In the last century, a revolution in telecommunications has greatly altered communication by providing new media for long distance communication. The first transatlantic two-way radio broadcast occurred in 1906 and led to common communication via analogue and digital media:


 * Analog telecommunications include traditional telephony, radio, and TV broadcasts.
 * Digital telecommunications allow for computer-mediated communication, telegraphy, and computer networks.

Communications media impact more than the reach of messages. They impact content and customs; for example, Thomas Edison had to discover that hello was the least ambiguous greeting by voice over a distance; previous greetings such as hail tended to be garbled in the transmission. Similarly, the terseness of e-mail and chat rooms produced the need for the emoticon.

Modern communication media now allow for intense long-distance exchanges between larger numbers of people (many-to-many communication via e-mail, Internet forums). On the other hand, many traditional broadcast media and mass media favor one-to-many communication (television, cinema, radio, newspaper, magazines).
