The book examines the regulation of the Kenyan media market, focusing on how market structure, competitive behavior, journalists’ conduct, and the financial performance of media houses shape the nature and diversity of content available to audiences. It provides a longitudinal and historical analysis of the development of the Kenyan media market, tracing its evolution from the monopoly of public service broadcasting to the dominance of private and commercial broadcasting. The book compellingly argues that a combination of both public and private media ownership has the potential to offer content that serves the public interest, even in a highly competitive environment. The study demonstrates the significant value of combining qualitative and quantitative content analysis with media economics and management models in studying the media market and applying methods for computing media market concentration, competition, and diversity performance.
