The document discusses four case studies of social media marketing campaigns. The NavyForMoms campaign was successful by facilitating listening, energizing, embracing and supporting through a social network that allowed mothers to connect over having children in the Navy. The MadMen campaign added value by personalizing avatars that could be shared, incorporating social validation. However, Skittles and Burger King campaigns failed by not adding value and lacking listening, talking, embracing, energizing or supporting aspects. The key lessons are that social media requires facilitating positive social interactions and adding value in order to be effective.
