Step 1: Understanding the Concept:
The Diffusion of Innovations theory, developed by Everett Rogers, describes how new ideas, products, or technologies are adopted within a social system.
The theory categorizes consumers into five distinct adopter groups based on their willingness to adopt an innovation, following a standard normal distribution curve.
Step 2: Detailed Explanation:
According to Rogers' model, the five adopter categories and their respective percentage shares of the adopting population are:
1. Innovators: The first individuals to adopt an innovation. They are risk-tolerant, adventurous, and make up 2.5% of the population.
2. Early Adopters: Opinion leaders who adopt early but with more care than innovators, making up 13.5% of the population.
3. Early Majority: Pragmatic individuals who adopt new ideas just before the average person. They make up 0% of the population.
4. Late Majority: Skeptical individuals who adopt an innovation only after the majority of society has accepted it. They also make up 0% of the population.
5. Laggards: Traditional individuals who are highly skeptical of change and are the last to adopt an innovation, making up 16.0% of the population.
To find the two groups that constitute the maximum combined share:
- Combining the Early Majority (34%) and Late Majority (34%) yields:
\[ 34\% + 34\% = 68\% \]
This combined group represents the vast majority of the market (68% of all adopters).
No other combination of two groups yields a higher percentage.
Therefore, the correct pair is the Early Majority and Late Majority.
Step 4: Final Answer:
The two groups that constitute the maximum percentage share in the product adoption process are the Early Majority and the Late Majority, which corresponds to Option (B).
