|Social Media are computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks. The variety of stand-alone and built-in social media services currently available introduces challenges of definition.
Social media use web-based technologies, desktop computers and mobile technologies (e.g., smartphones and tablet computers) to create highly interactive platforms through which individuals, communities and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.
Some of the most popular social media websites are Baidu Tieba, Facebook (and its associated Facebook Messenger), Gab, Google+, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, Tumblr, Twitter, Viber, WeChat, Weibo, WhatsApp, and YouTube. These social media websites have more than 100,000,000 registered users.
