Book excerpt: The power and influence of the mass media grows daily, crucially affecting the way all of us see and understand each other. The No-Nonsense Guide to Global Media introduces readers to the political economy of the major mediafilm, television, radio, recording, publishing and the Internet. Peter Steven looks at the ever greater concentration of ownership and at the convergence of technologies and media functions. At the same time, he emphasizes the diversity of local media production and media around the world. The media is more than the economics of ownership and the technology of production, he stresses; it is also audiences, in all their annoying and wonderful diversity.
