Part 7/8:

The evolution of cinema continued into the 1930s, with breakthroughs in sound synchronization and the emergence of "talkies" in the United States. While other countries experienced a slower transition, the success of sound integration led to the introduction of film scores, significantly enriching the viewing experience.

The first film to feature synchronized sound was "The Jazz Singer" (1927), which combined spoken dialogue, music, and silent film elements. Following this, "The Lights of New York" (1928) became the first entirely synchronized sound film. Additionally, the first stereophonic film, "The Power of Love," was released in 1922, utilizing two projectors to create a 3D effect with colored glasses, although it did not gain significant popularity at that time.
