For example, traditional media is an extension of the human body, while the new media is the extension of the human nervous system. The emergence of new media will change the equilibrium between human sensual organs and affect human psychology and society. The extension of human senses will change our thoughts and behaviors and the ways we perceive the world. That's why McLuhan believed when a new medium appears, no matter what the concrete content it transmits, the new form of communication brings in itself a force that causes social transformation.
