The New Media Theory series investigates both media and new media as a complex ecological and rhetorical context. The merger of media and new media creates a global social sphere that is changing the ways we work, play, write, teach, think, and connect. Because this new context operates through evolving arrangements, theories of new media have yet to establish a rhetorical and theoretical paradigm that fully articulates this emerging digital life.
