Who would be the audience for your media product?

Before I started making my film I created a questionnaire to find out the main age groups that watched and enjoyed Thriller films. I Asked 10 people of various ages, and as an outcome I found that from the age from about 15 and up.
I decided that I was going to make it appeal for 15 upwards. Most types of thrillers I found to be more favoured were, jumpy with flashbacks from the past and present. So due to the answers I got from my questionnaire, I used many flash backs and tried to make the audience ask many questions by the change in the tenses.
