Target Audience: Age Range

I feel that aiming my magazine at a certain age demographic is essential. If I try and aim it at too wide a group of people then it may be unlikeable. I don't want the magazine to be for people of a young age, because the genre of the music is BritPop, which is a genre that many people would have been keen on in the 90's. I think a suitable age range for my magazine would be from about 16-40, as I want it to be trendy and modern, but not something completely main stream, as the genre of music isn't one that is main stream in this day and age. I think that I will make a magazine mainly aimed at people between the age of 16 and 40. In order to do this, I must use sophisticated language and sustain a high level of interest.
