Book excerpt: This book provides a state-of-the-art account of corporate blogs as a new form of corporate communication studied from corpus-based and discourse perspectives. Using a range of analytical techniques to examine a large corpus of 500 randomly selected corporate blog posts, the book examines how language works in the novel and hybrid context of online communication at different levels of linguistic description, including vocabulary use (keywords), phraseology (lexical bundles), stance expression and the generic structure. The findings are interpreted in functional terms in this book in order to provide an overall characterization of this new and evolving corporate genre.
