What’s mobile in mobile communication? [PDF]
Interrogating the terminology of “mobile” communication, this article notes that media and communicative practices have been mobile for millennia. What’s mobile about cell phones and other current mobile media is a new range of contexts in which personally meaningful and socially consequential interactions become possible.
