Elvis Presley wasn't born in 1956, but his career was. He began the year barely known outside the south, but under the management of Col. Tom Parker he spent the year making his mark on TV variety shows hosted by Milton Berle, Steve Allen and Ed Sullivan; and his recordings for RCA, beginning with "Heartbreak Hotel," dominated the pop charts. By the end of the year he was arguably the best-known entertainer in America, with broader fame still to come.
