Medium is the message is the term that describes the content of the media or a character that can be easily grasped. The phrase in itself comes from McLuhan's theory "Understanding media".
The expression "the medium is the message," coined by Marshall McLuhan, refers to how the form of a media ingrains itself in the message, forming a symbiotic relationship in which the medium influences how the message is perceived.
"The medium is the message" is a theory by Marshall McLuhan, stating that the form of communication used has a greater impact on society than the actual message conveyed.
The phrase "the medium is the message" was coined by Canadian philosopher Marshall McLuhan and was used to describe how the medium used to deliver a message can affect the way it is interpreted and understood. For example, a message delivered via a newspaper is likely to be interpreted differently than one delivered via a television broadcast. The medium used to deliver a message can also influence how it is received and remembered.
