The substantial level of investigative activity to date into information systems and technology

acceptance and diffusion has witnessed the use of a wide range of exploratory techniques examining

many different systems and technologies in countless different contexts. The aim of this paper is to

provide a comprehensive and systematic review of the literature pertaining to such adoption and

diffusion issues in order to ascertain the current “state of play” of the field along a number

dimensions. Information on a series of variables were extracted after conducting a review of 345

articles on Innovation adoption, acceptance and diffusion, published in 19 peer reviewed journals

between 1985 and 2007. Findings suggest that the positivist paradigm, empirical and quantitative

research, the survey method and TAM theory was used predominantly when investigating the topics of

adoption and diffusion of technology. Results of this research may have implications for researchers,

journal editors, reviewers and universities
