Recently, scholars of new media have been exploring the relationships between genre theory and new media. While these scholars have provided a great deal of insight into the nature of e-genres and how they function in professional contexts, few address the relationship between genre and new-media theories from a designer's perspective. This article presents the results of an ethnographic-style case study exploring the practice of a professional new-media designer. These results (a) confirm the role of dynamic rhetorical situations and hybridity during the new-media design process; (b) suggest that current genre and new-media theories underestimate the complexity of the relationships between mode, medium, genre, and rhetorical exigencies; and (c) indicate that a previously unrecognized form of hybridity exists in contemporary e-genres.
