Diffusion of innovations research has altered the research trajectories of those in the field of communication. In this article, the authors briefly explore the evolution of diffusion research, in terms of theoretical influences and applied research advances, and then address how the evolution of diffusion of innovations provided the impetus for a communication discipline identity search. An explication of how diffusion of innovations can be viewed as mechanistically affecting media convergence is presented. This piece closes with a call to return to diffusion research, especially given the face of current communication vehicles and media convergence."Our problem is to learn why, given one hundred different innovations conceived of at the same time-innovations in the form of words, in mythological ideas, in industrial processes, etc.-ten will spread abroad while ninety will be forgotten" (Tarde, 1903, p. 140). The first words of Diffusion of Innovations, considered to be the seminal work of this theory, are the words of Gabriel Tarde (Rogers, 1962). The study of the diffusion of innovations began in World War II was taken up famously by Everett Rogers (Rogers, Singhal, & Quinlan, 2008) in the 1960s, and since then, social scientific fields-particularly the field of communication-have contributed to the ebb and flow of this theory's trajectory and uses.These fluctuations warrant further exploration. The goals of this article are twofold: (a) to briefly trace the course of Rogers' diffusion of innovation framework and examine the communication discipline's unique
