A mass culture emerged in both the 1920s and the 1950s due to the economic prosperity found in both time periods. These economic booms were both caused by the end of WW1 and WW2.
"Mass culture" is commonly used to describe culture that comes through the centralised production processes of the mass media. It should be emphasised, however, that the term's validity is still being debated, as evidenced by Swingewood's (1977) classification of it as a myth. When it is linked to the concept of mass society, it becomes a specific form of a broader theme: the relationship between social meanings and the allocation of life chances and social resources. Mass culture, as a store of social meaning, is one of several words that encompass high (or elite) culture, avant-garde culture, folk culture, popular culture, and (later) postmodern culture.
