From the Japanese tsunami and Boston Marathon bombings to the Arab Spring in the Middle East, social media has proven its power to save lives. The second edition of this acclaimed text examines how rapidly evolving social media and Web 2.0 technologies have changed the crisis management landscape. New information in this edition includes how to keep an "incident" from becoming a "crisis," how to properly handle criticism, brand management, and crowdsourcing. With case studies drawn from recent news events, the book provides the techniques required to communicate effectively and avoid potential bad press that could result from information mismanagement.
