Prior research that has used the Technology Acceptance Model (TAM) to predict Internet usage has focused on perceived ease of use and perceived usefulness of websites. More recently, in an extension of TAM to include an intrinsic motivator, perceived playfulness was found to be another important factor in user acceptance of websites (Moon and Kim, 2001). Since then, no other research found has validated the significance of perceived playfulness. The purpose of this study is therefore to validate Moon and Kim’s extended TAM by exploring the importance of the intrinsic factor “perceived playfulness”, in the context of information-searching sites on the Internet.
