- Technology adoption lifecycle
The technology adoption lifecycle is a sociological model, originally developed by Joe M. Bohlen and George M. Beal in 1957 at
Iowa State College. [Citation

Everett Rogersbroadened the use of this model in his book, Diffusion of Innovations.
The technology adoption lifecycle model describes the adoption or acceptance of a new product or innovation, according to the demographic and psychological characteristics of defined adopter groups. The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve." The model indicates that the first group of people to use a new product is called "innovators," followed by "early adopters." Next come the early and late majority, and the last group to eventually adopt a product are called "laggards."
demographicand psychological(or " psychographic") profiles of each adoption group were originally specified by the North Central Rural Sociology Committee, Subcommittee for the Study of the Diffusion of Farm Practices (as cited by Beal and Bohlen in their study above).
The report summarised the categories as:
* innovators - had larger farms, were more educated, more prosperous and more risk-oriented
* early adopters - younger, more educated, tended to be community leaders
* early majority - more conservative but open to new ideas, active in community and influence to neighbours
* late majority - older, less educated, fairly conservative and less socially active
* laggards - very conservative, had small farms and capital, oldest and least educated

Adaptations of the model
The model has spawned a range of adaptations that extend the concept or apply it to specific domains of interest.
In this book, "
Crossing the Chasm", Geoffrey Mooreproposes a variation of the original lifecycle. He suggests that for discontinuous or disruptive innovations, there is a gap or chasm between the first two adopter groups (innovators/early adopters), and the early majority.
Educational technology, Lindy McKeown has provided a similar model (a pencil metaphor [ [http://www.teachers.ash.org.au/lindy/pencil/pencil.htm Pencil metaphor ] ] ) describing the ICT uptake in education.
