Dagnes (Shippensburg Univ.) argues that dramatic changes in the mass media have sullied the operation of US politics. More specifically, she contends that the glut of cable, satellite, and new media outlets have worked to drive Americans apart and make true discourse more difficult to achieve. In her analysis, she examines how politicians have adapted to the many changes in the media--most notably in their understanding and subsequent use of vertical integration to gain greater visibility throughout the electorate. Dagnes further laments the blurred role of journalism today and suggests that while citizen journalism has its merits it has led to a media that is much less accountable to journalistic standards and consequently, the citizenry at-large. The end result of the 24-hour, on-demand nature of the contemporary media is a politics devoid of substance and fueled by an entertainment driven ideology. In short, Politics on Demand succeeds as a Neil Postman-esque critique of the contemporary mass media. Summing Up: Recommended. All readership levels. R. M. Alexander Ohio Northern University
