Censorship has always been a topic of discussion among filmmakers and the lawmakers. Though our country’s constitution gives freedom of expression, it makes sure that the expression does not result in conflicts. Indian Film Industry produces thousands of films per year. Every film has to cross censorship in order to get a release. This research studies the changing trends in the censorship of Tamil films. To be precise, the research focuses on films released in the past three decades. i.e. from 1980 to 2009. The findings of textual analysis suggest that there are drastic changes in the censorship pattern in each decade since 80s.
