Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread.

There are five main elements which influence the spread of a new idea: the innovation itself, adopters, communication channels, time, and a social system. Relies heavily on social capital. The innovation must be widely adopted in order to self-sustain. Within the rate of adoption, there is a point at which an innovation reaches critical mass.

Innovation Diffusion Theory (IDT), developed by Everett Rogers in 1962, explains how new ideas, products, or technologies spread within a society or social system over time. It provides insights into the adoption process and factors influencing the acceptance of innovations.

Key Elements of Innovation Diffusion Theory:

Adoption Process Stages:

Categories of Adopters:

Factors Affecting Adoption Rate:

Applications:

• Technology adoption (e.g., smartphones, software).
• Healthcare innovations (e.g., vaccines, telemedicine).
• Marketing strategies for product launches.
• Sustainability practices (e.g., renewable energy adoption).

This theory remains widely used in social sciences, marketing, and business strategy to understand how innovations gain acceptance and spread.
