We conducted a quantitative meta-analysis of previous research on the technology acceptance model (tam) in an attempt to make well-grounded statements on the role of subjective norm. Furthermore, we compared tam results by taking into account moderating effects of one individual-related factor (type of respondents), one technology-related factor (type of technology), and one contingent factor (culture). Results indicated a significant influence of subjective norm on perceived usefulness and behavioral intention to use. Moderating effects were found for all three factors. The findings yielded managerial implications for both intra-company and market-based settings.
