Bullying is a prominent problem that greatly impacts the lives of teens everywhere and there have been various initiatives to raise awareness and help stop bullying in schools across the country. In July, ABC Family, Seventeen Magazine and Twibbon launched an anti-cyberbullying campaign on Twitter and Facebook after ABC Family aired the biting drama “Cyberbully.” Formspring also took steps to help stop bullying and Barack and Michelle Obama used Facebook to help spread their anti-bullying message. Now Time Warner has teamed up with Facebook to help stop bullying through a new social pledge app called “Stop Bullying: Speak Up.”

The app, named after the original initiative that was launched by Cartoon Network, is targeted towards bystanders who witness bullying. It encourages students, teachers and parents to take actions that will stop bullies in their tracks. Users can take the pledge, share stories, recruit others to join the movement and create their own bullying prevention groups on Facebook for their particular school. The app includes a personal message from Anderson Cooper as well as articles about bullying, hazing and how to make a difference.

Marne Levine, Facebook’s VP of Global Public Policy, spoke about this new initiative. Levine said:

The Stop Bullying: Speak Up social pledge app is rooted in the fact that students, educators and parents have the power to stop bullying by speaking up when they see it occur. The launch of this campaign reinforces our deep commitment to the safety and security of kids everywhere. By working with Time Warner, our hope is to inspire millions of people who witness bullying to take action.

Facebook, CNN, Cartoon Network and Time Inc. are attempting to reach hundreds of millions of people through their campaign which spreads across numerous platforms. In addition to the app, CNN is hosting their second Anderson Cooper 360° Town Hall special about bullying. The special will air from Rutgers, The State University of New Jersey, and premieres on Sunday, Oct. 9 at 8 p.m. EDT. During the special Anderson Cooper will investigate why kids bully each other as well as speak to family, students and experts.
