Marxist theory emphasizes the importance of social class in relation to both media ownership and audience interpretation of media texts: this remains an important factor in media analysis. Whilst content analysis and semiotics may shed light on media content, marxist theory highlights the material conditions of media production and reception. 'Critical political economists' study the ownership and control of the media and the influence of media ownership on media content cannot be ignored. It also remains important to consider such issues as differential access and modes of interpretation which are shaped by socio-economic groupings. Marxist media research includes the analysis of representation in the mass media (e.g. political coverage or social groups) in order to reveal underlying ideologies. We still need such analyses: however oppositional it may sometimes be, audience interpretation continues to operate in relation to such content. Because of the distribution of power in society, some versions of reality have more influence than others.
