Research in to Most Popular Audience For Horror Films/ My Chosen Audience

I have chosen a target audience of ages 15-25 both male and female because from doing some research on the internet, I found this was the most profitable audience. This audience visits the cinema more than any other age range and because they are a younger generation, but not too younge, they are used to using modern technology so I would be able to advertise my film in a variety of ways. I feel that this audience likes a wide range of films, but I will do some further audience research so I can gain information on what their interests, activities and most importantly, what they think about films.
