Encouraged by the Covid-19 pandemic, which has disabled the quality or at least the usual work of most institutions, especially those in the service of culture, this work will try to show the impact of the Covid-19 pandemic on museum institutions and the cultural sector. The museum is known to us as a cultural institution whose goal is the development of society, and its task is to collect, preserve, research and represent material narrations of man and the environment, for the sake of science, education or entertainment. The museum is the so-called a database of the items it keeps. The scientific discipline that studies museums and their activities is called museology, and belongs to the information and communication sciences. Lately, in step with the times we live in, museum audiences have been forced to explore content through a variety of digital channels and platforms. Museums are expected to keep up with the times and prepare for the digitization of their contents, which the vast majority of museums in Eastern Croatia have failed to do, and which we will learn more about through interviews with museum leaders. An important role in this is played by museum management, a phrase created from two words that can survive without each other, but together they form an important tool in museum management. One of the most important questions that modern museum management must answer is how to use new technologies, and one of the basic prerequisites for their application is to ensure the availability of materials to museum users. Ensuring the availability of materials is one of the most important indicators of the quality of the museum's business. The paper seeks to prove the main hypothesis: "COVID-19 pandemic contributed to greater attendance of online cultural content." We will try to confirm the hypothesis by two methods: interviews with three leading people of museums in Eastern Croatia, and surveying museum visitors. In order to obtain as relevant data as possible, the interviewees answered the same set of questions. We will also consider the theoretical part of the paper to be an important part of the paper, which speaks more about the very definition of museum management, i.e. new trends in museum management.
