 In 1960, rock and roll was at its infancy, and there was doubt among the parents and the older generation that the music would even last. Even record companies would take their time putting their toes into the rock and roll pool. One of the first changes in the record world was in the 1950s. There was a transition from the 78 RPM record format to the 45 RPM, which really represented the pop recording. In 1958, the 45 disc replaced the 78 completely.
