As a part of everyday life, the media has important, maybe even primary place in ones life. Along with the usefulness, informing, entertaining and educating its own consumers, the media also provide something that we are often not aware of - shaping our minds and influencing our perception of social reality. The very influence of mass media on the audience is an inexhaustible topic that has intrigued many analysts, statisticians and media professionals. One of the first to be interested in this topic is George Gerbner. In the sixties he founded the theory of cultivation. It is one of the most influential theories that examines the long-term consequences of watching television. This theory has been included in the Cultural Indicators project, which has been able to prove how television has a small but continuous impact on the perception of the social reality. This project is mentioning the terms of heavy and light TV viewers. The most general hypothesis of cultivation analysis is that those who spend more time living in the world of television are more likely to see the real world in terms of the images, values, portrayals, and ideologies that emerge through the lens of television. The first research into the theory of cultivation was about examining the influence of the media on the spectator's perception of the world of crime, violence and justice. Apart from cultivating aggressive tendencies, television provokes an exaggerated sense of distrust and dangers. In addition to crime, Gerbner also lists seventeen topics suitable for cultivation research. Some of these topics are interpersonal relationships, experiencing other cultures, experiencing oneself, political participation, etc. Further development of the media also develops cultivation theory. It is reasonable to assume that the Internet today takes on the role previously occupied by the television. Social networks are special areas of the Internet, whose cultivating effect can be noticed on an everyday basis, especially in younger generations. Although the largest numbers of cultivation researches have been made on television and the Internet, even older media, such as newspapers and radio, have their own cultivating effects, and it seems that every media will have them as long as they have someone who consume them.
