Social Communication is a field of study that mainly explores the ways information can be perceived, transmitted and understood, and the impact those ways will have on a society. Thus, the study of Social Communication is more politically and socially involved than the the study of Communication, even tough it takes the former in great regard.
Several Communication-related graduation courses in Brazilian universities, for instance, are named Social Communication (or, even better, Comunicação Social). These graduation courses involve the study of broadcasting, Journalism, Telecommunication, Publicity, television, radio and Public relations, among others. Furthermore, these courses encourage the study of subjects of other areas- such as Art and Mathematics.
Links for a few Social Communication courses, and related topics, are given below.
