In the context of cultural studies, the idea of a text includes not only written language, but also films, photographs, fashion or hairstyles: the texts of cultural studies comprise all the meaningful artifacts of culture.[citation needed] Similarly, the discipline widens the concept of "culture". "Culture" for a cultural-studies researcher not only includes traditional high culture (the culture of ruling social groups) and popular culture, but also everyday meanings and practices. The last two, in fact, have become the main focus of cultural studies. A further and recent approach is comparative cultural studies, based on the disciplines of comparative literature and cultural studies.[citation needed]
