Ok, so for this marketing course i'm taking, we have to create a whole marketing plan for a product; also, we have to choose a specific group we're targeting. Our group chose the Apple iPod targeted to females ages 18-35. In hindsight, this probably wasn't the best choice, but we had to choose some segment that hasn't really been targeted by this product.

Basically i need any statistical information i can get about portable mp3 players. I've been looking through all sorts of university business databases and can't find anything. The main thing i'd like to know is what products own what share of the market. The marketing software we have can't get that specific. The closest i can get is "portable electronics".

Can anyone help?

Also, does anyone know of any women that have actually purchased an iPod, or at least a portable mp3 player of some sorts?
