How useful is a production of culture perspective in understanding the birth of Rock & Roll?

The theory tells us a lot about the social and economical factors that create a platform for something new in the music industry. Peterson theory suggests that they’re six factors for the emergence of Rock and Roll: Changes in law, development of certain technology, Industry structure, organisation structure, occupational careers and changes in the market. These are very useful in understanding how the platform for Rock & Roll was created but however they do not explain why it was Rock and Roll that became so big. Why didn’t Latin Music or R&B become so big? That’s the problem in analysing the birth of Rock and Roll in this perspective. It is still useful in understanding the birth of Rock and Roll, as the changes in culture play a major part in its creation but the theory fails to suggest why it was Rock and Roll that was the chosen one.
