Hollywood’s dominance of the movie industry has been the subject of numerous studies. An interdisciplinary literature review in this thesis identified twenty different single or multiple factor explanations that try to account for Major studio dominance at different time periods but cannot comprehensively explain how Hollywood acquired and maintained dominance for nine decades. This thesis reviewed the economics, management and marketing literatures to identify existing theoretical explanations for the acquisition and persistence of market dominance. It then integrated existing theories identified within the business literature into a ‘theoretical lens’. This lens enables an historical analysis of Hollywood’s longstanding dominance of the movie business to be undertaken from a strategic business perspective. This thesis concludes that the Major studios rise to market leadership and enduring dominance can primarily be explained because they developed and maintained a set of strategic marketing management capabilities that were superior to rival firms and rival film industries. It is argued that a marketing orientation and effective strategic marketing management capabilities also provide a unifying theory for Hollywood’s enduring dominance because they can account for each of the twenty previously identified explanations for that dominance. The original contribution of this thesis is the development of a strategic marketing management lens and a set of guiding questions that can facilitate a strategic analysis of market dominance in any industry.
