This paper examines the effects of composition, size and structure of virtual networks on the diffusion of information. The research extends the Axelrod cultural model (ACM), an established theory rooted in political science research, to explain information dissemination among social actors in ICT-enabled virtual networks (Axelrod 1997). The investigation is focused on the impact of network structure parameters and gives insight on how a manipulation of those parameters influences the diffusion of information in virtual networks.
