The Hollywood musical is recognized as a distinguished part of motion picture history, playing an integral role in the evolution of movies during the 1920s through the 1950s. Today, despite this fact, most people are unaware of how they originally got their start. The development of moving pictures with sound during the 1920s paved the way for the era of Hollywood musicals. Prior to the development of the musical, as we know it, were some vaudeville fillers produced in the early 20th century that included music. While accepted by the audience, they were never as popular as the full-scale production Hollywood musicals that America came to love.
