The Adoption Process

Learning Outcome: By the end of this lesson, you will be able to describe the five adopter categories in the diffusion of innovation model and explain why marketers target each category differently.

What Is the Adoption Process?

The adoption process describes how a new product, service or idea spreads through a market over time, as different people decide to try it at different points. The most widely used version of this model was developed by Everett Rogers (1962), who classified adopters into five categories based on how quickly they take up something new relative to everyone else in the market. Rogers built on decades of earlier research into how new farming practices and technologies spread through rural communities, and adapted it into a general model that today is applied just as often to smartphones, streaming services and financial products as it once was to hybrid seed corn.

The Five Adopter Categories

Rogers’ model divides the market into five groups, each with a roughly predictable share of the total (Rogers, 1962). Innovators, around 2.5% of the market, are the first to try something new, often before it is even fully proven, and are comfortable with risk and technical uncertainty. Early Adopters, around 13.5%, follow quickly, are typically respected within their social or professional circles, and often act as informal opinion leaders others look to before buying. The Early Majority, around 34%, are more deliberate: they wait for some social proof that a product works before committing. The Late Majority, another 34%, are sceptical and tend to adopt only once a clear majority of their peers already have. Laggards, the final 16%, are the most resistant to change and may adopt only once an older alternative is no longer available at all.

Example: Brindlewood Smart Thermostat

A fictional company, Brindlewood, launches a smart home thermostat. In year one, its Innovators are hobbyist early testers who buy directly from a crowdfunding page before the product is even in shops, about 400 of Brindlewood’s eventual 16,000 total customers. By year two, Early Adopters, tech-comfortable homeowners who read reviews and want to be first among their friends, push sales past 2,600. It is only once the Early Majority start buying in year three, after seeing installed units in neighbours’ homes and hearing that the app is reliable, that sales genuinely take off, eventually accounting for over a third of all units sold. Brindlewood’s Late Majority and Laggards do not buy until the thermostat is a mainstream, unremarkable choice, several years after launch.

Why the Model Matters for Marketers

Each adopter category responds to a different message and a different channel, so treating the whole market the same way from launch day wastes marketing spend. Innovators and Early Adopters respond well to technical detail, direct engagement, and the appeal of being first; the Early Majority respond better to demonstrated reliability, reviews, and visible use by people similar to them; the Late Majority and Laggards often need the product to have become the safe, unremarkable default before they will consider it at all. A launch strategy built entirely around Innovators can struggle to ever reach the Early Majority, since the two groups are persuaded by almost opposite kinds of evidence, which is why many product launches focus heavily on winning over credible Early Adopters as a bridge into the much larger Early and Late Majority segments that make up roughly two-thirds of the eventual market. Pricing often follows the same logic: an early, higher launch price aimed at Innovators and Early Adopters who are less price-sensitive can later be lowered to bring in the more cautious, more price-conscious Majority segments once the product has proven itself.

The Adoption Process and the Product Life Cycle

The five adopter categories map closely onto the stages of the product life cycle: Innovators and Early Adopters drive the slow early growth of the Introduction stage, the Early and Late Majority fuel the sharp rise and eventual plateau of the Growth and Maturity stages, and Laggards are often still buying as a product enters Decline. Understanding which adopter group is currently driving sales gives a much clearer read on which life cycle stage a product is genuinely in than sales figures alone.

A Related but Separate Idea: Reference-Group Influence

The adoption process is sometimes discussed alongside earlier research by Francis Bourne into how reference groups, the people whose opinions a buyer values, shape product and brand choices (Bourne, 1957). Bourne’s work is about social influence on individual purchase decisions generally, rather than the five-category adopter model itself, but the two ideas connect naturally: Early Adopters often function as exactly the kind of reference-group figures Bourne described, which is part of why their endorsement carries so much weight with the Early Majority who follow them.

Key Idea: A market adopts a new product in five predictable waves, Innovators, Early Adopters, Early Majority, Late Majority and Laggards, and each wave needs a different message, so a launch strategy should shift its appeal as the product moves from one adopter group to the next.

Summary

Rogers’ (1962) adoption process model splits a market into five adopter categories, each roughly predictable in size and each persuaded by different kinds of evidence. Winning over credible Early Adopters is often the key bridge to reaching the much larger Early and Late Majority, and the adopter groups track closely with the stages of the product life cycle. Related reference-group research by Bourne (1957) helps explain why early adopters carry so much social influence over the buyers who follow them.
