Social media

Social media are media for social interaction, using highly accessible and scalable publishing techniques. Social media uses web-based technologies to turn communication into interactive dialogues. Andreas Kaplan and Michael Haenlein define social media as "a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, which allows the creation and exchange of user-generated content."Businesses also refer to social media as consumer-generated media (CGM). Social media utilization is believed to be a driving force in defining the current time period as the Attention Age. A common thread running through all definitions of social media is a blending of technology and social interaction for the co-creation of value.
