Bollywood is the informal name given to the popular Mumbai-based Hindi language film industry in India. The term is sometimes used incorrectly to refer to the whole of Indian cinema. The name is a blend of Bombay, the English name for Mumbai, and Hollywood, the centre of the American film industry. Though some purists deplore the name, arguing that it makes the industry look like a poor cousin to Hollywood, it seems likely to persist and now has its own entry in the Oxford English Dictionary. Such names have also been used for other industries, including Kollywood, Tollywood, Lollywood, Dallywood, and Nollywood.
