If information flows from the media to the opinion leaders and from them to the target audience, the process is known as

The correct option is Multi- step flow.

To understand why this is the correct answer, let us break down the concepts of information flow in communication theory:
1. One-Step Flow Theory: This model suggests that media effects are direct, immediate, and uniform on the audience. Information flows directly from the media to the target audience.
2. Two-Step Flow Theory: Formulated by Paul Lazarsfeld and Elihu Katz, this theory posits that most people form their opinions under the influence of opinion leaders, who in turn are influenced by the mass media. Thus, information flows from mass media to opinion leaders, and from them to a wider population. Since there are two levels/steps of transmission, it is traditionally called the two-step flow.
3. Multi-Step Flow Theory: This is an expansion of the two-step flow model. It acknowledges that the influence of media is complex and multi-directional. In this model, information can flow from media to opinion leaders, and then from those opinion leaders to the target audience (as described in the prompt), as well as through various other social relations, sharing, and interactions. Because it represents a more complex web of diffusion that is not restricted to exactly two rigid steps, it is widely referred to as the multi-step flow of communication.
