The diffusion of innovation includes:

1. Innovators: these people tend to be risk takers who are highly educated and who use multiple information sources
2. Early adopters: these are people who are leaders in their social setting. They tend to be respected by their peers
3. Early and late majority: these two groups represent the bulk of population. The early majority are deliberate decision makers who have many informal social contacts. The late majority are far more skeptical of new products and below average in social and economic status
4. Laggard: these people have a strong fear of debt and price conscious. Their sources of information are primarily family and close friends.
