Journalistic illustration plays a crucial role in conveying information, expressing aesthetic style, and shaping popular culture. In Vietnam, the tradition of journalistic illustration is deeply influenced by the École des Beaux-Arts de l’Indochine (Indochina Fine Arts School), notably prominent during the resistance war period (1945–1975), when illustrations simultaneously served artistic and propagandistic functions. Amidst the profound digital transformation of modern journalism, studying the inheritance and evolution of illustration styles has become an urgent need to preserve cultural values while guiding the aesthetic development of electronic newspapers. This paper focuses on two main aspects: (1) the historical and artistic value of journalistic illustration during the resistance period, examined through representative publications such as Mặt trận Kinh tế, Nhân dân, and Tiến lên..; (2) the stylistic transition of illustration from traditional print newspapers to electronic media, with a research focus on official Vietnamese electronic newspapers: VOV and Dân Việt… The study clarifies the extent to which traditional artistic heritage - especially the Indochina style - influences contemporary illustration trends in the digital era. The contribution of this study is interdisciplinary, linking fine arts, journalism, and communication technology. Beyond its academic value, the research offers practical implications by orienting the development of modern yet rich journalistic illustrations for digital media. Thus, this paper helps establish a new research foundation on the intersection between traditional art and digital communication in Vietnam.
