The adoption of videoconferencing during the emerging phase of the technology and 'network effects'. Referring to the critical mass theory and 'users community network effects', proposals are formulated concerning the reasons why new users may adopt a new interactive media. In this paper, we are trying to study these ' network effects ' first through a longitudinal study of the adoption of videoconferencing by firms during the past twenty years and secondly through an empirical inquiry in twenty six firms which adopt this new media. Results tend to formulate how a new adopter can compete with these ' network effects ' by creating a users network.
