Social media definition.

Social media describes web-based applications that allow people to create and exchange content. We use the term to include blogs and microblogs (such as Twitter), internet forums (such as Doctors.net), content communities (such as YouTube and Flickr), and social networking sites (such as Facebook and LinkedIn).3 There is also the concept of ‘one to many users’ – a document or piece of media that can be edited by two or more geographically separate individuals, hosted by a web-based service such as Google Drive or Dropbox.
