Who would be the audience for your media product?

I created a profile of my target market from the previously research I completed:

Penumbra Effect - This is when you attract people outside your target audience. Although my magazine is targeted at 20-25 years old, people who are older and have been interested in mod for longer may be attracted to the magazine. They may be interested in modern generation of mod and therefore buy the magazine.
I may also get some people who wouldn't say they were a mod but are interested in niche music magazines. They may be a huge music fan that they want to check out the new music magazine that is on the market.
