The word "Bollywood" is derived from Bombay (Mumbai) and Hollywood, the center of the American film industry. However, unlike Hollywood, Bollywood does not exist as a physical place. The term "Bollywood" has origins in the 1970s, when India overtook America as the world's largest film producer. The naming scheme for "Bollywood" was inspired by "Tollywood", the name that was used to refer to the cinema of West Bengal. Dating back to 1932, "Tollywood" was the earliest Hollywood-inspired name, referring to the Bengali film industry based in Tollygunge, whose name is reminiscent of "Hollywood" and was the center of the cinema of India at the time.
