market research

for my magazine my target audience would be 13-30 years of age males, this doesnt mean these are the only people that i want to read my magazine because for all i know there is a 70 year old women out there somewhere who listens to rap and she has every right to buy my magazine if she wants. Im choosing to put
"sexiest women of 2011: featuring Beyonce, Rihanna, Alexis Jordan" because obviously being men they would like to see pictures of these 'sexy' women and in order to do this they would have to buy my magazine to see these exclusive pictures just for 'freestyle' magazine which therefore means im selling more magazine.
Im also using the names Snoop Dogg and Wiz khalifa because they are very well known, brilliant artists with a huge reputation in the music world which will also attract more costumers to buy my magazine.
