In a society in which the importance for the active involvement of each individual in the process of (re)shaping and (re)defining society are becoming ever more pressing, the need for a paradigm shift in the status of the spectator is particularly felt in the experimental forms of contemporary theatre. In this process of search and redefinition, the very term 'spectator' is no longer entirely accurate or all-encompassing, as it is reduced to the activity of witnessing or watching. Depending on the various forms of artistic manifestation, including performative installations or smartphone apps, we may rather use terms such as participants or users, observers and equally objects of observation, going as far as the idea of co-creators and co-performers. The article is analysing this paradigm shift based on some productions of the renowned German theatre collective Rimini Protokoll, focusing in particular on the Stefan Kaegi/Rimini Protokoll's "Société Anonyme", which premiered in November 2023 in Hamburg.
