In a fruitful piece, Peterson and Becker 1975 looked at the concentration of the music industry to gauge its effect on innovation and diversity in music. DiMaggio 1977 was interested in the type of administrative system that operates in cultural industries. Neither craft nor bureaucratic administration, commonly found in other parts of the economy, seemed to characterize the cultural industries. Industries. Instead, DiMaggio poists, they work on a brokerage system of administration, in which a person (the broker) acts as an intermediary between the artists and business mangers. Artists would prefer to have the freedom of creative expression available under craft administration and managers would prefer the predictability inherent in the bureaucratic model, but neither system of administration would be effective. Examples of brokers include the commissioning editor in book publishing, the artist & Repertory person in the recording industry, and the producer in television and movies.
