The network Twitch hosts a novel form of collective viewing of audiovisual products, whose audience is centennials. We analyse the case of Watch Parties, which allow users to watch films in real time with a streamer. Taking three Watch Parties of the streamer Lynx_Reviewer as a case study, a methodological triangulation is carried out: virtual ethnography, content analysis and semi-structured interview. By exploring the phenomenon, a model of analysis of collective consumption of content is constructed thanks to a descriptive systematisation of the audience’s consumption habits and uses by analysing the conversations and messages generated in the transmissions. The results obtained show that, despite the disparity of content and channels broadcasting on Twitch, this format follows a common pattern of broadcasting, participation, interface and type of messages. It is a leisure experience based on the collective construction of content developed synchronously with the interaction of the audience, which uses its own references and expressive codes to communicate, using films as a means of interaction within the community.
