Theodor Adorno and Max Horkheimer's theory

THEORY

Adorno and Horkheimer adopted the term 'culture industry' as it produced music the same way as manufactures produced vast quantities of consumer goods . They argued that the culture industry exhibited an 'assembly line character' which could be observed in the ' synthetic, planned methods of turning out it's products. ' 

They liked the idea of ' the culture industry' to a model of 'mass culture' in which cultural production had become a routine, standardised repetitive operation that produced undemanding cultural commodities which in turn resulted in a type of consumption that was also standardised, distracted and passive.

Their view of cultural production has, with some justification, often been portrayed as the pessimistic lament of cultural Ellis's who were dismayed at what they perceived to be the homogeneity and vulgarity of 'mass' and taste.

Money makes the system go round thats why they pick stuff that is defiantly going to be liked by the population. Therefore anything new and different is rejected. Culture industry is the same as manufacturing industries. Products were maid according to rationalised organisational producers that were established for the sole purpose of making money.

STANDARDISATION 

Making a formula for something that is going to be very successful. Popular songs now have standards that need to be reached when making.
Hit songs are mechanical and manipulative operation purely by commercial going.

PSEUDO

Adorno and Horkheimer were every critical of what they refer to as pseudo individuality.The way the culture industry assembled producers that made claim to originality but which when examined more critically exhibited little more than superficial differences. 

 Lock and keys- they're all different but exactly the same. 
The whole uniqueness lies only in very minor modification.
