The purpose of this study is to investigate the evolving relationship between intention and information systems usage over time. Our main argument is that as individuals get into the habit of continuously using a system, the predictive power of intention will be diluted. Consequently, the more usage is performed out of habit, the less cognitive planning is involved. The research model is tested in a longitudinal setting and the results present strong support to the hypotheses. The moderating effect of habit on the relationship between intention and usage increases over time, while the impact of intention on IS continued usage weakens over time. In addition, prior behavior is found to have a strong and significant effect on continued usage. The implications of this study are noteworthy for both researchers and practitioners.
