Technological advances in communications tools, the Internet, and the advent of social media have changed the ways in which nonprofit organizations engage with their various constituents. Nonprofits now have a constellation of tools including: interactive social media sites, mobile applications (apps), Websites, and mash-ups that allow them to create a comprehensive system for mobilizing supports to advocate for changing public policies. From Facebook to Twitter and from YouTube to Pinterest, communicating to many via words and images has never been easier. The authors explore the history of nonprofit advocacy and organizing, describe the social media and technology tools available for moving advocacy goals forward, and conclude with some possible challenges that organizations considering these tools could face.
