This study aims to provide a comprehensive overview of the current state of user-generated content (UGC) research within the context of new product development (NPD). A systematic literature review (SLR) was conducted across three prominent databases, namely Web of Science, Scopus, and Science Direct, using keywords to identify relevant articles. 5585 of 13,381 articles were deemed relevant following the application of inclusion and exclusion criteria. These articles were then thoroughly analyzed to create a comprehensive review of the topic. The selection process involved evaluating the titles and abstracts of all publications that were discovered, and carefully choosing 136 articles for full-text review. From these, 58 articles were ultimately selected for detailed analysis in this study. The study highlights the role of UGC in augmenting NPD process and identifies potential areas for future research based on evidence derived from an SLR of articles published between 2012 and 2023. The research methodologies adopted in this paper involve descriptive analysis and TCM framework (T-themes, C-contexts, and M-methodologies). Finally, the article concludes by shedding light on its potential applications by providing four themes and highlighting the importance of future research in the field with five propositions.
