In communication, media (singular Medium) are 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. The beginning of human communication through artificial channels, i.e. not vocalization or gestures, goes back to ancient cave paintings, drawn maps, and writing.
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.
Media technology has made communicating increasingly easier as time has passed throughout history. In some communities, access to electronic media (such as television) and print media (such as newspapers) are important indicators of development.
