Definition in plain terms
Diffusion of innovations is Everett Rogers' theory of how new ideas and products spread: adoption flows through a population in a bell curve of psychographic segments — innovators (2.5%, novelty-seekers), early adopters (13.5%, the respected visionaries others watch), early majority (34%, pragmatists needing proof), late majority (34%, skeptics needing pressure), and laggards (16%). Each segment adopts for different reasons, on different evidence, from different messengers.
The mechanics
Rogers also named WHY innovations spread at different speeds — five attributes: relative advantage (how much better), compatibility (fit with existing habits and values), complexity (how hard to understand), trialability (can it be tested cheaply), and observability (can others SEE it working). The marketing translation: each launch phase needs its segment's evidence (novelty for innovators, vision for early adopters, references and safety for majorities), and product design can buy diffusion speed directly — free trials are engineered trialability, public usage is engineered observability. Moore's chasm later located the curve's treacherous gap between early adopters and early majority.
When it matters
Reach for it at launch sequencing (whom to court first and what to show them), at stall diagnosis (growth plateaus often mean a segment boundary — the message that won visionaries is scaring pragmatists), and at creative strategy (observability explains why visible products spread faster — and how to make invisible ones visible). It's the deep grammar under beachhead strategy, influencer logic, and every 'cross the chasm' deck.

Origin & history
Coined by rural sociologist Everett Rogers in Diffusion of Innovations (1962) — synthesizing 508 diffusion studies, beginning with Iowa farmers' adoption of hybrid corn; the adopter categories and percentages came from that data, and five editions later the book remains social science's second-most-cited work.
