Understanding such a concept requires an adjustment of thinking; we are so used to accepting the message as the important part of information technology that it is difficult to shift that importance onto a different aspect of the process.
Another of McLuhan's theories is the idea that advancement in communication technology has created (and is creating) a global village'. Technologies can be comparatively applied to our human senses, especially sound and sight. The telephone and radio extend the lengths of hearing as the television extends vision. Technology alters senses and perceptions steadily and without resistance, and McLuhan theorizes that this progressive change affects our learning strategies and information processing. (Symes).
Electric technology has allowed society to observe events occurring on the other side of the world as though they were happening locally. Communication advancement has virtually eliminated barriers of time and space, as the world seems to be getting smaller and faster because we can see things as they happen on the other side of the planet. It must be considered, of course that the impact of these extended senses' are less forceful than our primary senses. Watching war on television and watching it occur right in front of you create different sensations; however, it cannot be denied that the development of technology has allowed for a greater identification and consciousness of the world in a global context. .
McLuhan's argument is simply this, that the world is becoming more unified because of this information access. His interpretation of this unification is a global village', where technology changes social structures as well as people on a personal level. The speed at which information can travel and be processed allows for society to act and react to global issues at the same speed as conventional face to face communication. The advancement not only allows society to do so, but in fact, forces responsibility on a global level.
