Consumer adoption of new products and services involves several stages:
1) Interest - Consumers first learn about an innovation but lack knowledge.
2) Information Search - Consumers seek more information about how the innovation works and its benefits.
3) Trial - Consumers test the innovation on a small scale through samples or limited use.
Consumers also differ in when they adopt innovations - from Innovators who are first to adopt, to Early Adopters just behind them, to the Early and Late Majority, and finally to Laggards who are often the last or never adopt.
