The diffusion of interactive communication innovations and the critical mass: the adoption of telecommunications services by German banks

摘要: Abstract Interactive innovations are distinctive in that their adoption depends on the perceived number of others who have already adopted innovation. Thus rate does not take off familiar “S” shape until a critical mass adopters has been reached. Data 12 telecommunications services by 392 German banks used to explore our theoretical perspective role diffusion interactive innovations. The most important obstacle new is low degree (which suggests general importance mass). These obstacles do differ for innovators and other adopter categories. direct network externalities influencing should be determined each service, rather than assumed always exists.
