This final paper talks about social networks and their role in our lives. Today's modern era is characterized by digitization and internet culture, so this work starts from the history of media development. The era of electric media began with the telegraph, radio and television which gradually brought us into the age of globalization. The emergence of the internet is considered the most popular global communication phenomenon. In addition to this fact, it is important to question what we take for granted, and that is surfing the internet. One of the basic human values is privacy, but when using the internet, it is almost non-existent, but how is it that despite this fact, almost all of us are ready to use it? Privacy becomes compromised due to the collection of personal data. This is where we encounter the concept of privacy paradox where we notice how our privacy is exposed but we do not make changes to protect it. The question arises, in what way have social networks become a modern weapon used for the purpose of manipulation? The fact is that users are prone to possible manipulation and maneuvering of people’s thoughts and behavior. All of that comes from the fact that social networks are profitable industry and commercialization is essential for their survival. This is where target advertising and creating algorithms for the purpose of profit is born. Apps are also designed to be personalized, addictive and then to monetize the time that we spend using them. The media also plays a key role in shaping public opinion. As recipients of mass media our understanding of society is formed by what the media presents as relevant. In conclusion, we can note that the media is increasingly driven by profit and prone to manipulation. People have an innate need for interaction, fitting in and sense of community, and this is what drives the further development of social networks. Technology as such, deeply integrated into our everyday life, should be viewed critically for a better understanding of potential dangers.
