Indian cinema has undergone massive changes since its inception in 1913. It started with silent movies and transitioned to talkies in 1931 and colored films today. Dadasaheb Phalke is considered the father of Indian cinema for directing the country's first feature film in 1913. Over the decades, the themes of Bollywood films have shifted from being based on Hindu epics to focusing on family relationships and contemporary social issues. More recently, Indian cinema has gained international audiences and undergone a revolution in terms of production values, marketing, and box office revenues.
