Presley had grown up in poor neighborhoods and had been exposed to a culture that few middle-class children had been exposed to before. From there, he concocted a unique style of singing and dancing that would soon challenge entertainment industry standards. In the summer of 1953, Presley joined Sun Records to "record a personal record as a birthday present for his mother." Word of his talent spread around the studio and they quickly asked him to come back to the studio to test out a new song to sing. He eagerly returned and eventually began recording more songs. Sun Records played some of Presley's recordings to Memphis DJs and his work quickly gained popularity. He was soon invited to perform live and his contract with Sun Records was eventually sold to Colonel Tom Parker of RCA as his career and popularity began to improve rapidly. What made Presley unique was not necessarily his voice but the style in which he performed. This style has shocked and dismayed many people across the country. They thought he was inappropriate and should act in a more civilized manner. One of those people was Ed Sullivan, host of the family show Ed Sullivan Show. However, on September 9, 1959, Presley made his first appearance on the Ed Sullivan show.
