In the tourism sector, changes in performance due to the advent of digitalisation and advanced technology are very evident. Notably, this is reflected in the youth tourism segment, as young people are digital natives. Therefore, companies and travel agencies need to adapt to trends and constantly learn digital advertising techniques. In this thesis, we wish to investigate the effects of digitization on youth tourism and to examine changes in functioning of a tourism agency specializing in youth tourism, Collegium Mondial Travel. The methods we used were secondary analysis of theoretical sources, expert interviews and analysis of ads on social networks. The key finding is that digitalisation has a strong influence on youth tourism and its marketing. The influence is reflected in the changing youth sector and consequently, mandatory digital techniques that companies must use to achieve the desired success.
