Conflicting and complex forces are shaping the diffusion patterns of the Internet and e-commerce in South Asia. Drawing upon the literature on institutional theory, we explore the drivers and inhibitors of the Internet in South Asian countries. We examine the influence of the three pillars of institutions (Scott, 1995) on the digital world of South Asia. The paper discusses how regulatory, normative, and cognitive institution–such as laws, relationships, culture, and habit–have shaped the diffusion patterns of the Internet and e-commerce in South Asia.
