Definition: Innovation Adoption Curve an innovation model by Rogers ('62) that classifies adopters of innovations into various successive categories. It is based on the idea that certain individuals are inevitably more open for adaptation than others.
The 5 categories of Rogers' IAC are:
- Innovators (brave people)
- Early Adopters (respectable people, opinion leaders)
- Early Majority (thoughtful people)
- Late Majority (skeptic people)
- Laggards (traditional people)
Also called: Multi-Step Flow Theory or Diffusion of Innovations Theory.
