Commonly called new media theory or media-centered theory of composition, media theory focuses on how writing is created, keeping in mind particularly the tools and mediums used in the composition process. New media refers to a range of digital modes of communication, often incorporating a multi-modal mix of the visual or oral in addition to traditional text. Stemming from the rise of computers as word processing tools, media theorists now also examine the rhetorical strengths and weakness of different media, and the implications these have for literacy, author, and reader.
The meaning of the term 'new media' can be confusing and debated over. At times extended to mean any sort of media that is not purely written-text-based, it generally refers to any medium that is technologically 'advanced' from pure text. The broadness of the term is useful in that it allows for the multiple modes that can be encompassed by this definition, instead of being focused on the technical aspect that the term 'digital' would invite. With this in mind, though, terms like 'digital', 'hyper-textual', 'interactive', 'simulated', 'virtual', and 'networked' can often be helpful when thinking about what constitutes new media. However, there is often a false dichotomy drawn between the 'analogue' media and the 'new' media; media theory invites re-mediation of texts, which often result in a mix of mediums. Gunther Kress remarks on the new responsibilities of writers: "In the new theory of representation, in the present technological context of electronic, multimodal, multimedia textual production, the task of text-makers is that of complex orchestration. Further, individuals are now seen as remakers, transformers, of sets of representational resources... ."
Noted scholar in the field, Cynthia Selfe has frequently commented on the exigency of incorporating new media in the writing classroom, noting its ability to make students rhetorically aware of the arguments that they commonly take for granted based on medium. She states, "Composition teachers, language arts teachers, and other literacy specialists need to recognize that the relevance of technology in the English studies disciplines is not simply a matter of helping students work effectively with communication software and hardware, but, rather, also a matter of helping them to understand and to be able to assess – to pay attention to – the social, economic, and pedagogical implications of new communication technologies and technological initiatives that affect their lives."
Richard Ohmann extends this argument, saying, "Adults ignorant of computers will soon be as restricted as those who today are unable to read. Software will become the language of the future, and the dominant intellectual asset of the human race, so that an understanding of software will be a primary component of literacy in the electronic age".
