Althusser was a French Marxist philosopher, but believed that Marxism was more of a science than just a theory. He concentrated more on Ideology and said that it "represents the imaginary relationship of individuals to their real conditions of existence". This means that he saw Ideology as a means of control; it makes the subjects feel as if they are in control of their own destiny, but really they are being shaped by the ideas of the ruling classes. Althusser subscribed to the Marxist structure consisting of the superstructure and the base, but was anti-economic and anti-humanist. His core beliefs were related to ISA's (Ideological State Apparatus) and RSA's (Repressive State Apparatus). He considered that ISA's were institutions that sought to enforce the ideas and lifestyles of the ruling classes, such as the Media. RSA's were institutions that sought to protect the means of production, usually through threat of violence, such as the Government and Police.
News Corp and Advertising
This refers to the Marxist theory of determining the role of ownership, and also Althusser's theory of ISA's. As previously mentioned, Althusser saw the Media as an institution that upholds the ideals of the ruling classes. Media magnates such as Rupert Murdoch own a vast proportion of media output, and therefore control most of what we see and hear. If we subscribe to what Althusser says, then they can shape this output so that it represents the ruling classes ideas as dominant, and something that we should all aspire to. A possible example that this does happen could be the fact the Rupert Murdoch intervened in the Publication of Chris Patten's Memoirs, as he felt that some of the content would damage the reputation of his business interests.
Williamson and Semiology
Judith Williamson wrote the book "Decoding Advertisements" in 1978, which is still considered a classic text on the use of semiotics in advertising. Whereas most semiotic deconstruction looks to break down adverts into it's component parts and divulge meaning from them individually, Williamson sought to discover how the meaning behind adverts is created. She says that only the products that are essentially the same, or have the same function, need to be advertised. For example, essentially all soap powders have the same function. i.e. to clean your clothes. You therefore need to create difference in order to advertise it, and this is done through image. This image can then be used to define the social structure of classes, by aligning a particular product with a certain social group. Williamson goes on to say that adverts then change from selling goods, to selling yourself.
