Bollywood is the nickname by which the Hindi film industry, one of the largest film production centres in the world, is known. The letter B in Bollywood stands for Bombay, the former name of the city of Mumbai, the capital of the western Indian state of Maharashtra, where the Hindi film industry is based. Bollywood is a portmanteau word which combines Bombay and Hollywood. Hollywood is an entertainment district located to the northwest of the city of Downtown Los Angeles in the state of California, U.S.A. where the American film industry is located. The word Bollywood has recently been incorporated in the Oxford English Dictionary. However, many people abhor the word Bollywood, because they believe that it makes the Hindi film industry look like Hollywood's poor cousin.
