This article discusses the research of the linguistic landscape in the first decade of the 21. century. The author concentrates on research of written texts in the public space. He pays attention to the complexity of the discussed problems. This complexity results from the processes of globalization and migration that contribute to create social structures with great variety of languages used and with a heterogeneous ethnic composition. These dynamic social and national groups will be an interesting object of research also in the next years. This claim refers as well to the German speaking countries where speakers of many mother tongues live.
