This document is a postgraduate dissertation submitted by Stefano Stephanou that examines the concepts of globalization and glocalization, using Christmas as a case study. The dissertation consists of 5 chapters that discuss: 1) debates around globalization vs glocalization, 2) the history and commercialization of Christmas, 3) the methodology used in the study, 4) analysis of data collected, and 5) a discussion relating trends in globalization to marketing perspectives on glocalization and co-creation. The dissertation aims to argue that glocalization, not globalization, better describes how cultures globally accept, resist, or adapt celebrations like Christmas.
