The last decade has seen marketing strategy evolve rapidly in three major directions, which can be summarized in three Ds: Digital, Data-Rich, and Developing Markets. The first D refers to "digital"; digital marketing strategy deals with firms' judicious use of digital resources to create differentiated and sustainable value for customers. The second D is "data-rich"; digital marketing has made available to researchers unprecedented data on firm and customer behavior. The third D is "developing markets"; the issue of marketing strategy in a digital and data-rich context is particularly relevant in developing markets such as BRIC (Brazil, Russia, India, and China) countries. This article formally define the scopes of the three Ds, identify opportunities associated with three Ds, and highlights the work published in these areas that will hopefully trigger more research work in D 3 environments.
