Social media are media designed to be disseminated through social interaction, created using highly accessible and scalable publishing techniques. Social media supports the human need for social interaction, using Internet- and web-based technologies to transform broadcast media monologues (one to many) into social media dialogues (many to many). It supports the democratization of knowledge and information, transforming people from content consumers into content producers. Businesses also refer to social media as user-generated content (UGC) or consumer-generated media (CGM).

Social media can be said to have three components;

1. Concept (art, information, or meme).
2. Media (physical, electronic, or verbal).
3. Social interface (intimate direct, community engagement, social viral, electronic broadcast or syndication, or other physical media such as print).

Common forms of social media;

• Concepts, slogans, and statements with a high memory retention quotient, that excite others to repeat.
• Grass-Roots direct action information dissemination such as public speaking, installations, performance, and demonstrations.
• Electronic media with 'sharing', syndication, or search algorithm technologies (includes internet and mobile devices).
• Print media, designed to be re-distributed.
