Historically, cultural innovation flowed from the margins of society—from fringe groups, social movements, and artistic circles that challenged mainstream norms and conventions. Companies and the mass media acted as intermediaries, diffusing these new ideas into the mass market. But social media has changed everything.
Social media itself is a catch-all term for sites that may provide radically different social actions. For instance, Twitter is a social site designed to let people share short messages or “updates” with others. Facebook, in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities.
Social media often feeds into the discovery of new content such as news stories, and “discovery” is a search activity. Social media can also help build links that in turn support into SEO efforts. Many people also perform searches at social media sites to find social media content. Social connections may also impact the relevancy of some search results, either within a social media network or at a ‘mainstream’ search engine.
