The rapid development of the field of information technologies makes it impossible to find their accurate and precise definition, and thus one can find many different definitions depending on the author. Information technologies facilitate the creation, organization, management, exchange and use of information. It is important to know that due to emergence of information technologies and the trend of their global acceptance, business processes in all industries, especially tourism, have undergone a transformation. Tourism has been showing continuous growth for many years, and future predictions assume its larger increase in forthcoming years. As an important part of the economy, tourism has also faced the pressure of adapting to new technologies, but by their implementation, new ways of communication and business management and new services and products have been enabled. Management information systems, decision support systems, strategic information systems and many others have found their use in the business of tourism organizations. The Internet and smart connected devices offer new opportunities not only to tourism organizations but for their consumers also. Some technologies used in tourism, thanks to global connectivity, include cloud computing, data mining, artificial intelligence, virtual and augmented reality and numerous others. Ubiquitous connectivity, accessibility and speed of information exchange enabled by information technologies induced some new consumer behaviors and new trends that tourism organizations must monitor carefully in order to maintain a high level of competitiveness and consumer satisfaction.
