This book investigates how the transition from traditional media to online news environments fundamentally alters the relationship between political information, public authority, and the role of the citizen. David Tewksbury, a scholar in communication and media studies, synthesizes empirical research on digital information patterns with established theories of traditional media. He constructs a conceptual framework to explain how the speed, segmentation, and participatory nature of the internet redefine the consumption of public affairs.

Experts recognize this work as a foundational text for understanding the early-to-mid 21st-century digital media landscape. Readers frequently note the academic density of the prose, which makes it a standard reference for students and researchers in political communication.
