Madhava Prasad traces the origin of the term to a 1932 article in the American Cinematographer by Wilford E. Deming, an American engineer who apparently helped produce the first Indian sound picture. At this point, the Calcutta suburb of Tollygunge was the main centr of film production in India. Deming refers to the area as Tollywood, since it already boasted two studios with 'several more projected' (Prasad, 2003) 'Tolly', rhyming with 'Holly', got hinged to 'wood' in the Anglophone Indian imagination, and came to denote the Calcutta studios and, by extension, the local film industry. Prasad surmises: 'Once Tollywood was made possible by the fortuitous availability of a half-rhyme, it was easy to clone new Hollywood babies by simply replacing the first letter' (Prasad, 2003).From Cinema of India: Sarkar, Bhaskar (2008).
