Tourism affects the economy of the Republic of Croatia and contributes to its betterment. For a tourist product to attract the attention of the target audience, i.e., tourists, a communication process of advertising is used, which uses various media to achieve its goal. Communication is a fundamental feature of advertising and has existed since the advent of humanity. Advertising has evolved over time, and today modern and traditional ways of advertising are being studied. Since these two ways of advertising complement each other, the Croatian National Tourist Board uses and connects both to advertise its events. The Republic of Croatia is a member of the European Union that proposes the implementation of projects important for the development of tourism. The Croatian National Tourist Board has conceived a strategic plan with the aim of promoting the Republic of Croatia in tourism on the domestic and foreign markets by 2027. The key features of the strategic plan are based on the current methods of implementation, the current state of the tourism brand and strategic elements for achieving the final goal. As part of the strategic plan, the Croatian National Tourist Board has developed creative campaigns that focus advertising on target groups. It is important to point out that the Croatian National Tourist Board is committed to ecological tourism and encourages sustainable development in order to preserve the beauty of Croatia for future generations. Through all these activities, the Croatian National Tourist Board plays a key role in promoting the Republic of Croatia as an attractive tourist destination.
