The popularity of multimedia streaming services is rapidly increasing. In-depth knowledge of the users’ behaviour is one of the cornerstones of delivering optimal Quality of Experience in such services. In this paper, we present the results of three studies that investigate the patterns of users’ behaviour in Spain, Sweden, and Norway. Based on an analysis of the network traffic data and questionnaires from more than 270000 individual users and households, we identified user accesses over time as well as the users’ habits, preferences, and motivations. Our results show the stability of users’ behaviour across the countries and over time and the differences among the users and access types. The insights obtained in this study might provide valuable inputs for the design of future network management systems and multimedia streaming services.
