Bollywood is the informal name for the huge Hindi-language film world that grew up in Mumbai, India — the songs, the dancing, the long romantic movies that many people across Asia already know. It is not one company and not a district you can walk around; it is the industry, the way Hollywood stands for American movies. The name is a blend of Bombay (the old English name for Mumbai) and Hollywood. Though actually, India makes films in many languages, in many cities. Bollywood is the Hindi/Mumbai one that became the nickname the world uses. People sometimes stretch it to mean any Indian film, which people who follow Indian cinema may gently correct.
