Niche Markets

I just wanted to post some of the Niches I am looking at. So far they are the Gaming Niche(Gamers are crazy about their games and gizmos)! The Gaming Niche is huge, let's just say in the billions$$$ Health and beauty products are huge also, can I say billions again$$$ This is just a small sample of what I am looking at, as of today. It might change, depending on other factors.
