Model of media richness

Media richness theory states that all communication media vary in their ability to enable users to communicate and to change understanding. ... A primary driver in selecting a communication medium for a particular message is to reduce the equivocality, or possible misinterpretations, of a message.

The term "media wealth" was described in 1986 by Richard Daft and Robert Lengel for the first time in the context of the media wealth theory. Media wealth describes the learning density that can be transmitted by a specific communication medium.

Explanation:

Before the growth of electronic communication media, MRT was developed to help managers decide which medium was best suited to communicate a message in business situations.

Rich media, such as conversations and phone calls, were best considered to be not-routine messages, while lean media were considered acceptable to routine messages like unaddressed memoranda.

The media wealth has been extended in the past two decades to cover the strengths and weaknesses of new media – from email to websites, video lectures, voice men, and immediate messages.

In media-rich contexts, humans evolved. Facial communication was the only way to communicate for hundreds of thousands of years living in stable, close-knit social groups. The concept of media choice did not exist until about 5,000 years ago, because it was not one-to-one or nothing apart from smoke signals.
