Answer
Bing Crosby, a renowned multimedia star, paved the way for Perry Como's signature genre. Crosby's smooth vocals and relaxed delivery in the 1930s and 1940s laid the foundation for the easy-listening style that Como would later popularize. Crosby's success in film, radio, and recordings set the stage for Como's own rise to stardom, as he emulated Crosby's laid-back charm and crooning style.
