The focus of the paper is on the concept of media with an emphasis on new media, what are the media, how they affect the modern society of the 21st century and how we can use them in contemporary museology. Museology is a relatively young and interesting scientific discipline, which is why it enables an exciting and diverse study that allows us to better understand it. Understanding even the basic concepts of museology allows us to protect what we love, what elevates our cultural and intellectual spirit, achievements that represent us as a human race and most importantly ourselves because it allows not only protection but also the transmission of the meaning of cultural heritage. nations, and at the same time ourselves. The paper is primarily focused on Croatian museums and their use of social networks as a modern tool of new media for more successful and easier achievement of the goal of museums and museology as a scientific discipline. The ways in which Croatian museums use social networks, which social networks they prefer in relation to others, will be described, and a quantitative and qualitative data analysis will be conducted. With the proper and moral use of modern technology, we can accelerate many more irrelevant processes and focus on more important aspects and even preserve cultural heritage in ways that have not been possible throughout human history. Social networks are part of modern technology and also significantly speed up the process of transmitting messages or notifications that lead us to awaken awareness of what is important, what needs to be protected and how to properly protect it. We want to preserve certain values because of the very beauty they represent and therefore we need to take this topic seriously to allow generations who may not even be born to see that beauty as well.
