What is one way the advent of talking pictures changed the behavior of movie audiences?

The advent of talking pictures, or "talkies," fundamentally transformed movie audiences by enhancing their engagement and emotional connection to the films. Viewers became more invested in the narratives as dialogue added depth to characters and storytelling, leading to a heightened interest in plot and performance. This shift also encouraged audiences to develop preferences for specific actors and genres, ultimately changing the way films were marketed and consumed.
