Question

how did the film making became a prominent industry in bombay

Answer 1

For the period in cinematic history it represented, Bombay Talkies was considered to be an innovative and highly resourced movie studio. In line with international standards, the studios' facilities included sound and echo-proof stages, laboratories, editing rooms and a preview theater. The reputation of Bombay Talkies was further enhanced by employing experienced European technicians, the most prominent of whom was Franz Osten.

Bombay Talkies set a high technical standard for film making in India and was credited with introducing a level of professionalism to the medium of movie making and acting, reputedly higher than standards set by rival Indian film production companies. Bombay Talkies acquired a reputation for changing the aesthetics and technology traditionally associated with Indian films. It was also renowned for producing films on (then) controversial topics such as those dealing with love between an untouchable lower caste girl and a high caste Hindu Brahmin boy e.g. (Achhut Kanya).
