Help viewing all apps in iTunes

I see these charts where there are 1000+ Apps out specifically iPad and over 800 games alone, yet when I look in iTunes I see the same 40-50 over and over. I've tried click a category, the 'see more' in new and noteworthy but all I get is 2 pages at the most of about 30-40 apps. How can I browse all the Apps available? Do they have it setup that only top apps show up, and to see any other apps you have to know what they are and do a search for them? Thanks for any help.

I found if you type iPad in the search then select apps for iPad you get a LOT more results.

Only on the desktop version...on the iPad I have no idea how to crack into the other thousand apps...lol.
