This paper deals with participatory communication in the field of the promotion of cultural institutions. Creativity is an important factor in the success and effectiveness of marketing communication. This phenomenon has not yet been explored in relation to the creativity of user-generated content. This research addresses the question of whether creativity is a significant factor in the success of UGC (user generated content). Analysis of the outputs generated by the recipients of the communication issued by the Getty Museum in Los Angeles – and their interpretation of the works of art available to the museum. We used a modified method of evaluating creativity developed by Smith et. al. (2007). We used correlation analysis to analyze our data. The findings show that creativity is an important factor in the design of the communication strategy rather than in the success of specific UGC products.
