When trying to explain the Diffusion of Innovations theory to students, I always felt breaking it down to a simple analogy made it more palatable.
The first group are the innovators for whom owning the latest everything is a passion and an end in itself. The innovators proactively seek out new products to try them out, requiring almost no marketing efforts from your part. The next group are early adopters in search of competitive advantages provided by new products and services. The early adopters view technology as a means of achieving breakthroughs and aggressively gaining market edge.
The first two groups (the Innovators and Early Adopters) are visionaries. They want revolutionary change, something that sets them apart qualitatively from their competitors. They are the people who buy brand-new technology, before it’s been perfected or proved or before the price has come down. They usually have small companies and are willing to take enormous personal risks.
