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

Peterson's theory doesn't actually explain the birth of Rock n' Roll, instead it goes into extensive detail on the surrounding events and occurrences. Peterson discusses the state of the radio networks and the impact the television had on the music industry. He also talks about the transition into vinyl and how they made an impact in the purchasing and shipping of records, but what he doesn't explain is why this leads to the birth of Rock n Roll music. He talks about the FCC and how after the television became popular, they accepted the backlog of applications for independent radio stations which then led to the boom in popularity in records from independent record companies, but again, Peterson fails to get across why it was Rock n Roll music that became so popular. Peterson's views are most useful and informative, but on understanding the birth of Rock n Roll, which he says the article does, the article proves to be not so useful after all.
