The Internet began impacting on our ordinary lives only in the late 1990s, with the development of the World Wide Web (Gillies and Cailliau, 2000, Giovannetti, et’al., 2003). Since then, the Internet has been used extensively for accessing instantaneous information and communicating across geographical boundaries. Due to its characteristics of speed, efficiency and economy, the Internet began to be applied increasingly across industries ranging from retail and banking to the media (Giovannetti et al., 2003).
The emergence of social media in the new millennium gave the World Wide Web a new name, ‘Web 2.0’ (Breakenridge, 2008). Though social media has various definitions, in essence, it is a medium for people to collaborate and share content via Internet tools ranging from video-sharing, photo-sharing and blogs to social networking websites, virtual worlds and micro-blogs (Mersham, Theunissen and Peart, 2009).
