This document discusses the evolution of digital communication and new media technologies. It covers several topics: the definitions and differences between new media; communication theories including mediated communication and mass media; characteristics of new communication channels like the internet, email, and mobile phones; and computer-mediated communication (CMC) which can be synchronous or asynchronous. The key impacts of new media technologies are that the constraints of scarcity, time, and space in communication have been removed, allowing information to be shared more openly and control to shift from communicators to audiences.
