The topic of this thesis deals with the concept of cancel culture and its impact on information and media literacy in the 21st century. The cancellation culture is a relatively new phenomenon, based on the social ostracism of undesirable persons whom the law cannot successfully influence (politicians, actors, etc.) with the aim of fighting against systemic oppression. Unfortunately, with the development of social networks, the culture of cancellation has turned into a craving for spectacle caused by mass psychology, where often the oppressed become the oppressors. Information spreads at high speeds, making searching, critical thinking, and evaluating information an important aspect of navigating the waters of the Internet. Through several introductory terms, the topic of the paper will be presented. In the second chapter, he will refer to the concept of culture of cancellation, the beginnings of this phenomenon and the development of the archetypes that can be observed. The third chapter will deal with the concepts of information and media literacy, the development of these two aspects together and the way in which they come together. The fourth chapter will be dealt with through case studies, that is, examples of the culture of cancellation in public and their effect on society and on the individual, and how information and media literacy can help us. The conclusion will gather the information and data from the paper into one whole, pointing out the importance of information and media literacy in the context of the culture of cancellation.
