Nowadays, not only the content, but also the promotional work show the impact on the box office collections. The filmmakers strive to create more buzz about the film. The sharing of news related to the film to the public is good. It is only then that the public is interested in the film on the big screens. The cinema units are mainly aimed at young people to create a hype on their films.
The repetitive audience will only come if the film is too good and most of them would be young. So creating an interest for them on the film is a good strategy and all heroes are opting for it. This target audience was previously in Bollywood and eventually reached Tollywood as well.
