I am attempting to provide a short and sweet answer with a growing list of links to popular examples. This content was created for a meeting with a selected group of Vorgons trying to build a better website about intergalactic sewer maintenance and why they should be bothered with twitter to communicate their products and services.
Social media is information content created by people using highly accessible and scalable publishing technologies that is intended to facilitate communications, influence and interaction with peers and with public audiences, typically via the Internet and mobile communications networks. The term most often refers to activities that integrate technology, telecommunications and social interaction, and the construction of words, pictures, videos and audio. This interaction, and the manner in which information is presented, depends on the varied perspectives and "building" of shared meaning among communities, as people share their stories and experiences. Businesses also refer to social media as user-generated content (UGC) or consumer-generated media (CGM).
