This document provides an overview of social media and social networking, outlining how they have developed and changed communication. It discusses how in the past transparency and participation were limited to small circles, but now digital tools allow people to communicate globally. The key differences now are that people influence audiences through relationships and two-way communication rather than one-way broadcasts, and listen to their communities. It recommends having a clear social media strategy and mission, gaining leadership support, collaborating with audiences, and keeping communications flexible.
