In 1935 the Benny Goodman Orchestra had won a spot on the radio show "Let's Dance" and started showcasing an updated repertoire featuring Fletcher Henderson arrangements. Goodman's slot was on after midnight in the East, and few people heard it. It was on earlier on the West Coast and developed the audience that later led to Goodman's Palomar Ballroom triumph. At the Palomar engagement starting on August 21, 1935, audiences of young white dancers favored Goodman's rhythm and daring arrangements. The sudden success of the Goodman orchestra transformed the landscape of popular music in America. Goodman's success with "hot" swing brought forth imitators and enthusiasts of the new style throughout the world of dance bands, which launched the "swing era" that lasted until 1946.
