         "The role of the social network in the spreading of mobile services"

        Abstract:
        While there is ample evidence that social and communication networks
        play a key role during the spread of new ideas, products, or services,
        network effects are expected to have diminished influence in the
        stationary state, when all users are aware of the innovation, and its
        usage pattern is determined mainly by its utility to the user. Here we
        study four mobile phone-based services available to over six million
        subscribers, allowing us to simultaneously monitor the communication
        network between individuals and the time-resolved service usage
        patterns. We find that usage highly correlates with the structure of
        the communication network, and demonstrate the coexistence on the same
        social network of two distinct usage classes, network effects being
        responsible for the quantifiable differences between them. To test the
        predictive power of our theory, we demonstrate that traditional
        marketing techniques are ineffective in permanently boosting service
        adoption, and propose a hub-based incentive mechanism that has the
        potential to enhance usage for one of the two service classes.
