The Hindi film industry, known as Bollywood, is the largest sector of Indian cinema, headquartered in Mumbai, with a history dating back to 1896. Pioneering films like 'Raja Harishchandra' and the golden age of cinema from the late 1940s to the 1960s produced iconic movies and stars, marking significant advancements in storytelling and film quality. The 1990s saw a transformation with mixed genres and improved technology, while parallel cinema emerged during the 1950s and 1960s, focusing on realistic content but began to decline in the late 1980s.
