Technology adoption research has a tradition of using and improving Davis' (1989) “Technology Acceptance Model” (TAM) and extended versions of it. This article suggests a break with this tradition by showing that the TAM is limited in its understanding of technology adoption. Two alternative approaches are proposed that focus on the role of knowledge and user-technology match, and on the role of temporary dynamical contexts in the process of adoption decision-making. Together with the TAM, both approaches were empirically tested and compared to the TAM by incorporating them in a questionnaire regarding the adoption intention of HDTV in the Netherlands. Results show that the constructs of both approaches show significant relations with the respondents' adoption intentions of HDTV and, together, offer a good alternative to the TAM. This result can be seen as a basis for more future research that uses technological and contextual factors as a starting point for adoption research. Using this starting point will contribute to a better understanding of future technology adoption processes.
