Social Media is a variety of Web-based platforms and communities that enables people to create content and socially interact with each other online, and make the users active content publishers. Social Media includes forums, wikis, LinkedIn, Facebook, YouTube, Instagram, Twitter, Pinterest, blogs and other sites that are based on user-generated content (UGC).
The interaction on social Media can take many forms, and make the content sharing fluid among the users, but there are some common features such as: sharing photos, videos, posts and links; public profile updates (activity, location etc.), and commenting on the content that was shared by others.
In addition, the increasing growth of social media has also lead to another industry, called social media marketing which is a collection of promotional methods focused on social media instead of traditional advertising ones.
