A virtual community is a social network of individuals who interact through online media to pursue shared interests or goals, potentially across geographical and political boundaries. While online interactions cannot replace real-world community, social media supports human social interaction by allowing many-to-many communication over the internet. Both commercial organizations and political campaigns can use social networking to share their message and stories with audiences, build connections, and motivate supporters to action. Businesses in particular can benefit from using social media platforms like Facebook, Twitter, YouTube, and LinkedIn to meet and engage customers, share information, and promote their websites and brands.
