Media psychology provides valuable insights and methodology to improve the media experience and to understand its effects on recipients. Now that interactions and experiences are increasingly digitized in almost all areas of life, the contribution of media psychology to both business and society is becoming more critical than ever. In this chapter, we first discuss the main application of media psychology in business and then demonstrate how media psychology can contribute to current societal challenges. To this end, we present selected studies highlighting the contribution of applied media psychology to sustainability with a particular focus on Sustainable Development Goals (SDGs).
