What are the strengths and weaknesses of Peterson's production of culture approach to the birth of Rock and Roll?

Peterson's argument that Rock and Roll exploded onto the music scene in the mid 50's due to a number of influencial factors definitely holds alot of weight. On a personal level, having weighed up both sides of the argument, I believe that the "Baby-boom", one of the theories behind the rise of Rock is irrelevant due to the reasonable argument that these children weren't even early teens at the time of the rock explosion. I also disagree with the theory that the emergence of free thinking, creative artists like Elvis was accountable for the rise of Rock due to the fact that free thinking, creativeness is nothing new and didn't just appear out of the blue in the mid 50's. I do believe that factors raised by Peterson as possible reasons for the rise of Rock are very valued points and need to be addressed by anyone looking for a definitive answer to why Rock exploded in the mid 50's. Most notably the introduction of the cheaper, more durable vinyl record, the allowance of permits to small independent radio stations and the introduction of radios to cars. These factors I believe greatly contributed to the explosion of Rock and Roll.
