The coming of the microphone into radio and recording in the 1920s allowed softer-voiced, casual, and beguiling vocalists to woo and win the public. Happy-go-lucky Bing Crosby, who had been part of a trio within the Paul Whiteman organization, emerged as a soloist with a murmuring and mildly jazzy manner. Radio and movie shorts won the hearts of the ladies; he had an easy-Joe relaxed approach and a deeper voice than his crooner rivals. Virile males felt that Bing was how they sounded on a good bath day and were satisfied. By the mid-1930s Crosby had revived declining record sales and was starring in Hollywood movies. His smooth and swinging style dominated the next generations of pop singing and crooning became the cultural norm until the rock revolution.
