In addition to social communication, social networks have proven to be affordable, fast, inexpensive and effective marketing tool in business. Social networks are used by both, profit and non-profit companies and institutions to communicate their business values, collect data on consumers and get in direct contact with them, as well as to promote their products, services and events. The Covid 19 pandemic that began in 2020 had as a consequence a number of restrictions on movement, temporarily closed business processes in a number of industries and a limited or completely abolished spectator participation in various events, including sports. For this reason, many companies have taken advantage of the opportunities provided by digitalization and thus continue doing their business and event monitoring this way. This was also done by the organizers of the European Football Championship 2020. Along with other media, social networks have become part of the marketing activities that enable the transmission of matches, reports, results and other statistics. In this thesis, a survey was conducted on the experiences and attitudes of people who followed the European Football Championship 2020 through social networks. In accordance with the results, a comparison of the social networks Facebook and Instagram was made, in terms of their usefulness, reliability of information and availability of content during the championship. The comparative analysis found that both Facebook and Instagram proved to be equally good tools for monitoring the 2020 European Football Championship.
