From Crystal's blog:
"3. Marshall McLuhan thought of 'content' in any medium as always a representation of an older medium. For instance, print is the content of the telegraph. Do you agree or disagree? & What are your thoughts on repurposing (taking a property from one medium & reusing it in another)?"

My response:
It seems to me that new media will take the content from previous media and make it more accessible. It has been seen frequently nowadays that content from several previous media have come together into one that utilizes all of them in a way that borrows characteristics of each (for instance, the iPhone).
Repurposing, insofar as I've read about it, seems to be a necessary process in the advancement of media, since I'm tentatively defining this advancement as creatively applying previously unrelated content in new ways. Content, when it exists in different media, will therefore be interpreted through that media and will need to carry certain characteristics of that interpretation into its new incarnation in order to be familiar. That got convoluted at the end there, but I guess I'm saying content from a particular media will need to carry over aspects of its previous context, instead of just the content.
