New information technologies have often been treated as innovations for target users. Although users in recent times have had significantly more opportunities to be socialized with information technologies, the rapid pace of technology development usually means that every new technology represents a fairly major change over the previous one. Although a fairly significant body of research that empirically tests these alternative models and theories is now in existence, some questions with regard to the role of perceptions in innovation adoption remain unanswered. This paper reports the results of a field study examining adoption of an information technology innovation represented by an internet application. Moreover, the study examines the effects of an important moderating influence-personal innovativeness-on this adoption process. Finally, the study seeks to shed further light on the determinants of perceptions by examining the relative efficacy of mass media and interpersonal channels in facilitating perception development.
