Book excerpt: In this sharply argued book, McChesney explains why we are in the midst of a communication revolution which is at the centre of 21st century life. Yet this profound juncture is not well understood, in part because media criticism and scholarship haven't been up to the task. McChesney's concise history of media studies shows how communication scholarship has grown increasingly irrelevant in recent years, even as the media became a decisive issue of these times. The revolution in communication calls for a transformation in the way we think about media.
