In 1927, 'The Jazz Singer' became the first 'talkie'—the first feature-length motion picture with synchronized dialogue and music. It was an immediate blockbuster, and its success signaled the end of the silent film era. The film used the Vitaphone sound-on-disc system. Audiences were so captivated by hearing Al Jolson speak ('Wait a minute, wait a minute, you ain't heard nothin' yet!') that movie theaters across the country were forced to upgrade to sound technology almost overnight. This was the first major 'technological disruption' in blockbuster history, proving that audiences would always flock to the latest innovation.
