This volume features representative studies focusing on the evolution of text genres in corporate and professional communication. Genre change is explored in various contexts in light of the increasing importance of new media and the profound social changes that have occurred in the last few decades. Major theoretical issues are raised and discussed, highlighting the need to reconsider the repertoire of conventions traditionally identified in each specific genre, and to reassess and update the analytical tools used to investigate them, about three decades after the emergence of genre analysis.
