Media advocacy aims to influence public policy decisions through strategic use of mass media. It allows community groups to apply pressure to key decision makers by framing issues from a policy perspective and gaining access to news media. Effective media advocacy is based on solid planning principles like GOTME - defining goals, objectives, targets, messages, and evaluations. The biggest example is the worldwide ban on tobacco advertising. The target audience includes those with power to create change as well as groups that can apply pressure on them and the general public. Evaluation assesses if the issue gained media attention and if coverage advanced the desired message.
