i am getting only the history of indian cinema,but not getting the marketing aspect of the early era.for e.g. i got some material of marketing of "KRISH FILM".Like this if i can get some case study on marketing of old movies (any one movie)i.e.of 1960s,1970s,1990s,1980s etc.for that if we consider any one movie will do.e.g.like we can select ALAM ARA for 1950,than 'sholay" for 1970s,etc
