What is Bollywood?

The Indian movie industry is called Bollywood. It is a combination of two words: Bombay and Hollywood. Bombay, now known as Mumbai, produces more movies per year than Hollywood, and thus became known as Bollywood. These movies are renowned for their extravagant dance numbers, which originally pulled from all the dance styles around India. As such, we often refer to the dance style in the Bollywood movies as Bollywood dance.
