The contemporary media environment is dominated by promotional culture, a force which has captured not only commercial brands, but non-profit ones too. This thesis examines how four Christian campus ministries in Canada (Power to Change -Students, Inter-Varsity Christian Fellowship, The Navigators, and Catholic Christian Outreach) use Facebook to market their 'brands', recruit potential adherents and mobilize supporters to the Gospel. Drawing on the work of Peters (1999, 2006) it asks critical questions about the benefits of dialogue and dissemination, explores how these principles are implemented in social media environments, and considers the benefits and limitations for faith-based non-profit organizations. The study finds that campus ministries use some dialogic principles in their posts and interactions with users online, meeting certain prerequisites for dialogic communication. Yet it also shows that dissemination can be valuable for organizations that need to connect with audiences and compete with established brands in what is increasingly an ad-saturated mediascape. The study contributes to a broad range of scholarship, including literature on promotional culture, media and religion, non-profit communication, and social media.iii Acknowledgements I thank my committee, department, family, and more for all their help and commitment to my research.To my committee of Dr. Joshua Greenberg and Dr. Liam Cole Young: thank you for your time, suggestions, and sharing your expertise to produce this research project.Many other professors and faculty in the department have also been helpful in gathering resources and forming this research design.
