By that it aims to draw attention to Turkey as an interesting case in point for the study of the history of marketing practices in a non-Western context.\u0000\u0000\u0000Design/methodology/approach\u0000This study deploys a variety of largely unexplored material ranging from archival sources to newspaper reports and advertisements. In the first part, archival sources provided by the Nestlé archives (AHN) will be analyzed to present the company’s marketing strategy. As the amount on advertisements between 1952 and 1984 remained modest, the second part is devoted to the analysis of Turkish media reports to discuss Nescafé’s public perception.\u0000\u0000\u0000Findings\u0000The paper demonstrates that during the period under consideration the instable political and economic environment was pivotal for Nescafé’s marketing. Nestlé in the early years used similar strategies as in the West advertising Nescafé as a premium product for the upper middle-class. Due to import restrictions, it was a scarce and high-priced product. Nescafé succeeded to become a highly esteemed and sought-after product because it stood for Western modernity and prosperity. The study argues that it was not primarily Nestlé’s marketing that resulted in Nescafé’s considerable brand recognition but its public “visibility” through media reporting.\u0000\u0000\u0000Research limitations/implications\u0000This study is a preliminary attempt to investigate the history of instant coffee and its marketing in a non-Western market. The paper is mainly focused on Nescafé because it was and still is the most important brand in Turkey. Further, this paper brings into spotlight a country with distinct sociopolitical and cultural particularities which distinguish it from Western countries and allow to scrutinize how marketing practice and thought may develop in a non-Western setting. Further research is needed as Turkey's specific marketing environment is far from being thoroughly investigated.\u0000\u0000\u0000Originality/value\u0000By focusing on Turkey, this paper provides an insight into the specific ways Nescafé was marketed, consumed and perceived in a non-Western market.
