Live streaming was mainly used by organizations for things like broadcasting sports events, music performances, interviews, and conferences. Nowadays, in e-commerce industry, more people started using live streaming for various reasons, from promoting products to having interactive entertainment with their audience. In Indonesia, live streaming for online shopping has become very popular, especially on platforms like Shopee. On Shopee's live streaming, it's not just about showcasing products; it's also about encouraging people to buy during the live broadcasts. Our study applies a previously established adaptation of the Innovation Diffusion Theory (IDT) that incorporates 'Gratification' from the Uses and Gratification Theory (UGT) to explore its impact on purchase intentions in the realm of live streaming technologies. We conducted an analysis using data from 216 participants, employing Partial Least Squares Structural Equation Modeling (PLS SEM) to assess the influence of this combined theoretical model. Our research findings indicate that variables such as innovation diffusion, the level of satisfaction obtained, authentic experience, subjective well-being, and compatibility significantly influence consumers' purchase intentions during Shopee live streaming sessions. This means that companies, like Shopee, should keep working on making their live streaming better, as it makes people more likely to want to buy things. © 2024 International Conferences e-Society 2024 and Mobile Learning 2024.
