Information and Communications Technologies (ICTs) have drastically improved global connectivity and pervaded into most aspects of modern human life. To appropriate the benefits from ICTs, access to the required technology is an essential prerequisite. India’s ICT adoption has been fast since 2000, but with sizeable disparities across the country. This study identifies the diffusion pattern of digital communications services in India, while accounting for technological augmentation. The study also surveys the factors influencing the variations in regional ICT adoption in India and supports Rogers theory of innovation diffusion by investigating how the social systems impacts technology adoption at different penetration levels. The findings will be useful for infrastructure capacity planning, taking policy decisions and projecting the diffusion process of emerging consumer technologies for advancing digital inclusion to support inclusive development.
