The Diffusion of Innovations theory is a multi-step flow theory that examines the conditions that may increase or decrease the adoption of an innovation.
1. Unlike the 2Step Flow theory, it identifies the mass media as an important communication channel.
2. Like the 2 Step flow theory it takes into account the value of interpersonal relationships.
3. One has to have ample knowledge about an innovation before adoption.
4. An innovation has to be consistent with the receiver's existing values and past experiences of an audience before adoption.
