The development of information technology changes the way businesses conduct their marketing activities. Today, almost all companies are present on the Internet. The Internet as a form of communication every day expands the available markets to business entities and brings new opportunities for achieving business goals. Social networks as a phenomenon in the last decade are extremely important for the presence of business entities in the digital world. By developing the technology and the availability of the Internet as a communication medium to a large number of users, advertising through it becomes an unavoidable item for every business organization. Air traffic is one of the industry's fastest technological development. Air traffic becomes an increasingly important model for passenger transport. Over the past thirty years, aviation has experienced the greatest advances in comparison to other industries, and aircraft have taken the lead in the service sector. Technological changes have allowed a drop in air traffic services prices and a reduction in the operating costs of airline companies, and as a result, demand for services of this type of traffic is growing. Following the company's trends, airports need to invest more and more in their infrastructure to improve their services. Pula Airport is one of the nine airports in the Republic of Croatia. To expand and improve its operations, Pula Airport uses the official web site, social network Facebook and the official profile on the Routes Online web site. The thesis is focused on the development and importance of e-business of the Pula Airport.
