Tetrad Concept - McLuhan

The tetrad is a set of four questions to be asked of any technological artefact, including new media, and by extension, P2P Media. Originally formulated by Marshall McLuhan.

Context

"The tetrad is arrived at through a process of asking questions, based on historical, social, and technological knowledge of the subject:

• What does any artifact enlarge or enhance?

• What does it erode or obsolesce?

• What does it retrieve that had been earlier obsolesced?

• What does it reverse or flip into when pushed to the limits of its potential?"

These questions result in a set of four effects, namely: enhancement, obsolescence, retrieval, and reversal."
