"In this study, emerging media technologies were defined as: Email, mobile computing, podcasts, digital audio/media player, mobile communication device (e.g., BlackBerry), instant messaging, interactive web pages, and blogs."

American Journal of Business: "The most commonly applied ‘shorthand description’ of emerging media is that it is communications – of all types – based on digital technologies, and increasingly with interactive components. Among definitions designed to transcend user jargon, is that offered by Neuman (1991) more than a decade ago. He argued that what we define as emerging media will a) alter the influence of distance, b) increase the volume and speed of communications, c) enable interactive communications and d) permit the merging of media forms."

My definition:

Any mode of communication whether it be through pictures, blog posts, statuses, etc such as social media, online blogs, or websites.
