Despite their growing relevance, user innovation activities within consumer OCs still are underexplored. Members' motivations to innovate and contribute to OCs, in particular, belong to a young line of research requiring further investigation. This study contributes to this line of research by providing an in-depth netnographic analysis of innovative, privately operated OCs dedicated to tangible consumer products. Most fundamentally, we differentiate: (1) motives to join OCs, (2) motives to innovate, and (3) motives to publish innovations in OCs. It is the first study that categorizes the motives of innovative OC members depending on membership lifecycle and situational factors. Our results support companies in understanding members' motives in privately operated OCs relating to the company's brand or products. Thus, it provides a foundation for the development of specific incentives and tools that stimulate user activity. © 2011 Imperial College Press.en1363-919620114797836World Scientific Publishingmotivationnetnographyonline communitiesUser innovationWirtschaftJournal Article10.1142/S1363919611003568Other
