Which term refers to the process by which a product's idea spreads from a small group to a larger market?

• A. Diffusion (Markets)
• B. Innovation
• C. First to market
• D. Innovators

Answer: (A)

Diffusion is the process by which a product's idea spreads from a small group to the broader market. In markets, diffusion describes how the idea moves beyond early testers to wider customer segments, driven by factors such as the perceived advantage, compatibility with current routines, simplicity, the ability to trial, and how it’s communicated through social networks over time. Adoption typically follows an S-shaped curve as early adopters, then the early and late majorities come on board. This makes diffusion the best term for describing the spread across the market. By contrast, innovation refers to creating the new idea, being first to market is about timing of entry, and innovators are simply the initial testers.
