Step-by-step explanation:
Movies became a popular form of entertainment during the 1920s. People crowded into theaters to watch silent films, as they were the dominant form before the emergence of talking pictures in the late 1920s. They followed the plots by reading subtitles. These silent films allowed people to immerse themselves in different stories without the need for live narration or sound. The film industry saw significant growth, with technological advancements like CinemaScope and Cinerama that introduced new ways to engage audiences. Films from genres such as Westerns, dramas, and slapstick comedies were particularly popular. Silent films like The Cabinet of Dr. Caligari also contributed to global cinema by offering artistic and politically critical perspectives. By the end of the 1920s, weekly movie attendance had risen to ninety million people, signifying the immense popularity of film as a medium of entertainment and cultural unification.
