The Evolution and Applications of the Technology Acceptance Model

Abstract: This paper explores the Technology Acceptance Model (TAM), a framework widely used to predict the acceptance and adoption of new technologies across various industries. Originating in 1989, TAM has undergone several evolutions, including TAM2, TAM3, UTAUT and UTAUT2 to address its initial limitations. By focusing on core constructs such as Perceived Usefulness (PU) and Perceived Ease of Use (PEOU), TAM continues to play a significant role in understanding user behavior in relation to technology. This paper also discusses recent trends in TAM research, particularly in healthcare, education, consumer technology, and enterprise systems.
