The purpose of this paper is to explore the adoption of a social networking site called Facebook in context of a landlocked and one of the least populous states in India. The adoption of Facebook is examined by considering technology acceptance model (TAM) as a basic model along with additional constructs such as subjective norm and perceived trust in it. The data were collected from 202 young adults from couple of degree level colleges from one of the least populous and landlocked states called Sikkim in India. The empirical outcomes provided the positive significant connections between nine hypothesised relationships among seven constructs. The article also discusses the resulting theoretical contributions for Facebook adoption and discusses practical implications of Facebook adoption for Facebook providers and users.
