On the other hand, Brown (2002) modified TAM for developing countries. Brown’s model was tested in South Africa with external variables such as ease of findings, ease of understanding, self-efficacy and computer anxiety. The role of these variables to web-based technology acceptance was examined through PEOU. Brown (2002) argued that for a developing country, usage may not be influenced by PU. This increases the influencing effect of PEOU on PU as well as on usage (Anandarajan et al., 2002).
