Social media are interactive technologies that facilitate the creation, sharing and aggregation of content, ideas, interests, and other forms of expression through virtual communities and networks. Social media refer to new forms of media that involve interactive participation. While challenges to the definition of social media arise due to the variety of stand-alone and built-in social media services currently available, there are some common features:Social media apps are online platforms that enable users to create and share content and participate in social networking. User-generated content—such as text posts or comments, digital photos or videos, and data generated through all online interactions—is the lifeblood of social media. Users create service-specific profiles for the website or app that are designed and maintained by the social media organization. Social media helps the development of online social networks by connecting a user's profile with those of other individuals or groups.
