Internet of Behaviours (IoB) is an emerging phenomenon with significant business and societal impacts. This paper argues that Information Systems (IS) researchers, with their tradition of engaging with behavioural issues can play leading roles in shaping the IoB body of knowledge. Yet, there is a lag in IS research on IoB. To address this, the paper presents an exploratory content analysis of literature and webliography. This identifies several mutually complementary notions of IoB as a protocol, technology, data, system, and behaviour as well as IoB use cases and concerns. Then drawing from the Multi-Level Perspective (MLP), the paper provides an IoB conceptualisation framework and research direction. The framework makes the first attempt to offer IS researchers with conceptual facilities to explore and explain IoB, its application areas at different levels, and the tensions and struggles in IoB transitions.
