The emergence and development of informational technologies greatly facilitated the operation of a tour operator on tourism market. The main function of a tour operator in the market is organizational, which means that he is the creator and the organizer of the supply and the sale of his services is done by means of intermediaries (travel agencies) who directly sell their services to clients and bear no risk of unaddressed capacities while the tour operator bears the risk. As a rule, a tour operator does not have direct contact with clients and its location itself is not crucial to success as it is one of the main items to travel agencies. In modern tourism, the use of information and communication technologies (ICT) becomes a necessity and a condition for the progress of intermediaries. This paper presents Reiseanalyse from 2017, which gives a real picture of the German emissive market, as one of the largest tourism markets in the world. The challenges that were encountered by tour operators and their linking and creation of the offer they have today is presented through a comparative analysis of two tour operators. Internet has an immensely large role in their work and earnings. The conclusion of the paper itself is that the application of new informational technologies has equally influenced all the brokers in tourism and that they have evaluated on similar or the same path.
