Marshall Mc Luhan "The Medium is the Message"and Stuart Hall "Encode/Decode" - Charlotte, Jos, Charles-Antoine

In « The Medium is the Message », an excerpt from Understanding Media, Marshall Mc Luhan emphasizes on the importance of the medium in understanding its content.
Content, without any reference to it's medium is an [idea] that can be interpreted on many levels, as explained by Stuart Hall. Understanding the nature and origin of a medium aids in decoding [the dominant code]. In other words, the message is the medium because a message cannot be 'perfectly transparent' (in relation to the dominant hegemonic point of view) if we don't consider the medium in the analysis of the discourse.

Media is the vehicle by which we express our thoughts, or the initial « content ». Because Mc Luhan emphasizes the importance of the medium as being the message it could then be said that he's in agreement with Hall on the level of « subjective capacity ». Having subjective capacity enables people to decode messages perhaps more clearly; in order to do so, one must consider this in formulating any assumptions.
It could also be argued that someone without such subjective capacities might not be able to decode messages in the way they were intended, therefore such individuals could then fall in to the category , as described in Mc Luhan's article (the criminal). Without subjective capacity, one may be in danger of being assimilated by dominant, hegemonic manpulation.

Is it possible for technology to blur the line between medium and content? If so, to what extent?
