Four Products: Predicting Diffusion (2006)

by John T. Gourville


One of the critical tasks in the marketing of new innovations is predicting demand and rates of diffusion for those products. Focuses on four innovative products from different domains. Although one can speculate on the scope and rate of diffusion for each of these products independently, it's helpful to compare and contrast diffusion across these products. Doing so allows one to focus on the "levers" or product characteristics that influence product diffusion, making one product a star and another a dog. Importantly, looking across products allows one to pick up on things that get lost in discussing a single product.
