The thesis "The Internet as a strategy for entering the foreign market of a small and medium- sized enterprise" discusses the Internet as one of the most profitable internationalization strategies in modern times and the numerous advantages it provides. The body of the paper discusses the importance of Small and Medium Enterprises as the backbone of the world economy, pointing out their advantages and characteristics such as agility, flexibility, willingness to accept new technologies, innovation and others. Small and medium-sized companies are placed in the context of internationalization, i.e., the process of expanding to foreign markets, and the advantages and challenges that internationalization brings with it, such as potentially higher profits and increased competitiveness, as well as financial risks and other barriers. The need for internationalization is emphasized, as rapid globalization imposes ever greater and more intense competition and more demanding market conditions. The role of the Internet is defined as being the most important contributor to globalization that simultaneously creates increasing competition, but also makes the process of entering the global market easier than ever before. Solely by using the Internet, companies that engage in trade can expand their businesses outside of their countries' borders and even to the whole world and, at the same time, drastically reduce their expenses and connect better with their potential customers. The importance of digital marketing channels, which play a central role in e-commerce enabling companies to explore and offer their products in new markets, is especially emphasized and was supported by research conducted on three successful companies that operate internationally exclusively via the Internet.
