Right from the advent of Indian cinema in 1931, musicals with song numbers have been a regular feature in Indian cinema. In 1934 Hindi film songs began to be recorded on gramophones and later, played on radio channels, giving rise to a new form of mass entertainment in India which was responsive to popular demand. For over five decades, these songs formed the staple of popular music in South Asia and along with Hindi films was an important cultural export to most countries around Asia and wherever the Indian diasporas had spread.
