The theory outlines four distinct eras characterized by the dominant form of communication:
The Tribal Era
The Literate Era
The Print Era
The Electronic Era
The Tribal Era
Oral tradition was embraced as the primary means of communication.
The ear was the paramount sensory organ.
Storytelling played a central role in this era.
The Literate Era
Written communication flourished.
The eye became the dominant sense organ.
This era was marked by the creation of the phonetic alphabet.
The Print Era
Gaining information through the printed word became customary.
The eye remained the dominant sense.
The printing press brought knowledge to the masses.
There was less reliance on memory for knowledge due to the availability of printed materials.
Homogenization of society occurred as information became more standardized.
The concept of "The Public" emerged.
The Electronic Era
This is the era we currently live in.
Electronic media pervades our senses.
Electronic media has returned us to a state of tribalization, creating a "global village."
"The Medium is the Message"
The medium matters most, not necessarily the content it carries.
Content is still important, but…
The meaning of content is heavily influenced by the medium in which it is presented.
Examples provided to illustrate this:
Experiencing Shakespeare’s Romeo & Juliet (the medium through which you experience the story changes your perception).
Interpret Kennedy v. Nixon (1960) debates (the medium through which people watched the debate heavily influenced people's perception of each candidate).
