Participatory media include (but aren't limited to) blogs, wikis, RSS, tagging and social bookmarking, music-photo-video sharing, mashups, podcasts, video commentsand videoblogs. These distinctly different media share three common, interrelated characteristics:
- Many-to-many media now make it possible for every person connected to the network to broadcast and receive text, images, audio, video, software, data, discussions, transactions, computations, tags, or links to and from every other person. The asymmetry between broadcaster and audience that was dictated by the structure of pre-digital technologies has changed radically. This is a technical-structural characteristic.
- Participatory media are social media whose value and power derives from the active participation of many people. This is a psychological and social characteristic.
- Social networks amplified by information and communication networks enable broader, faster, and lower-cost coordination of activities. This is an economic and political characteristic.
