Bollywood (Hindi: बॉलीवुड, Urdu: بالی وڈ) is the informal term popularly used for Mumbai-based Hindi-language film industry in India. Bollywood is often incorrectly used to refer to the whole of Indian cinema; it is only a part of the Indian film industry. Bollywood is one of the largest film producers in the world, producing more than 1,000 films a year, with an audience of 3.6 billion people.
The name is a portmanteau of Bombay (the former name for Mumbai) and Hollywood, the center of the American film industry. However, unlike Hollywood, Bollywood does not exist as a real physical place. Though some 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.
Bollywood is commonly referred to as Hindi cinema, even though Hindustani, the substratum common to both Hindi and Urdu, might be more accurate. Bollywood consists of the languages of Hindi, Urdu and English. The use of poetic Urdu words is fairly common. There has been a growing presence of Indian English in dialogue and songs as well. It is not uncommon to see films that feature dialogue with English words and phrases, even whole sentences. There are a growing number of English films.
