Global advertising is a research field examining the strategies, processes, and impacts involved in promoting products and services across diverse international markets. It investigates how organizations navigate varying cultural, economic, and regulatory environments to create, adapt, and disseminate advertising messages effectively across national borders. The concept explores the challenges and opportunities of standardizing versus adapting campaigns, leveraging global and local media channels (including digital platforms), ensuring brand consistency while achieving local relevance, and understanding consumer responses across different geographies. Its significance lies in providing theoretical frameworks and empirical insights into successful international market communication, reflecting the critical role of advertising in global business expansion and brand building in an interconnected digital landscape.
