Reports are indicating that seniors’ rate of usage of technology is significantly increasing. Such change creates new market for companies. Majority of the existing literature examines the technology usage by junior adults (those younger than 50 years old). This study empirically examines the antecedents of seniors’ usage of computers. This research, thus, fills a gap in the literature and points out critical factors for practitioners. The data are collected using survey methodology. Three hundred twenty three participants provided the data used in the analysis of the model. Linear Regression is used to assess the hypotheses. The data showed that IT support and the different tasks, such as e-commerce and search, significantly impact the usage of computers by seniors. Satisfaction and security concern were also found to have an influence. The implications, directions for future research, and limitations are discussed.
