Theorist Guy Debord spoke of the Mafia and the recording industry.

    In the United States at least, it is already in the 
    recording industry, as in every other activity where 
    publicity of a product depends on a quite concentrated 
    number of people. It is easy to apply pressure to them, 
    with bribes and intimidation, since there is obviously
    quite a great deal of capital and hitmen who can not be 
    recognized nor punished. By corrupting the disc-jockeys,
    one thus decides what will succeed, from equally 
    wretched commodities. [1]
