How did Urban Outfitters become successful?

I am interested in looking at how this company recruited brands, and how they received enough money to start a store and then expand into national, and international known store. Also how the founder Richard Hayne took sole custody of this brand, and how it lasted in the horrendous world wide economy, when the clothes they sell are a middle to upper price range. I know a little enough that their stores are always bustling, but how?
