This work examines the causes and consequences of the "refocusing" phenomenon, where companies have stopped diversifying and begun focusing once more on their core product lines. Coverage includes a discussion of the effects of refocusing on market value, profitability and organizational structure.

This special issue of the Journal of Media Economics deals with diversity and diversification. Diversity, especially in broadcast programming, has played a major role in policy discussions on both sides of the Atlantic. The reason for the importance of the construct, however, is not often made explicit. Diversity in media content is important because the greater the variety or breadth of media content the greater the probability that media consumers can obtain utility or gratification from that content. Conversely, low diversity in media content means that consumers encounter fewer opportunities to obtain utility or gratification. Hence, consumer welfare is served by greater rather than lesser diversity. The articles in this issue are suitably diverse in the media industries on which they focus and in the countries represented by their authors. Van Kranenburg, Hagedoorn and Pennings take the publishing industry as their subject while Moreau and Peltier have researched the film industry. Einstein and McDonald and Lin report findings on diversity in the US television industry, albeit in different time periods.

​The decision to diversify lies at the core of corporate strategy and is one of the most important decisions for top management. Matthias Knecht introduces a new perspective on corporate diversification that extends the academic discussion and reveals substantial new insights with regards to one of the most pressing questions in strategic management: what makes a diversification strategy successful? The author introduces the dynamism of industries as the dominant force in the firm’s environment that influences the organization on all levels. Due to strategic, organizational, and managerial similarities of businesses competing in similar dynamic environments, synergistic benefits and superior economic performance can be realized through the combination of dynamic-related businesses in the corporate portfolio. This study provides a quantitative, multidimensional operationalization of industry dynamism and an in-depth assessment of the dynamism of a wide range of industries. At the core of the study lies the investigation of the performance impact of dynamic-related diversification strategies. The results provide new insights into successful portfolio construction strategies in the face of today’s dynamic environments.
