And of course, since modern men's clothing is so horribly dull and men just wear a t-shirt and jeans usually, that means the large majority of square footage in the mall is dedicated to women's clothing.
Back to those stores that aren't at the mall: 1. Bookstores are still at the mall, but only some malls. It's called "Barnes & Noble". Lots of malls have them. But you don't see the small ones like Waldenbooks any more; they're all gone. People aren't reading books as much any more, and a lot of people who do buy e-books. 2. Not many people buy physical music any more. If they do, they get it on Amazon. Otherwise, everything is either MP3/AAC downloads or streaming music services. 3. No one buys software in a box any more; you just get it online. And a lot of application software has gone by the wayside, to be replaced with SaaS, web apps, etc.
