I'm not so sure about the origin, but it's commonly used in design/UX to showcase one primary or "Hero" product, and refers to a large space front-and-center above the fold on a page. Think apple's site putting up a huge iPhone image on release day (http://www.sprint.com http://www.sprint.com is another good example). I think this likely started in physical product sites and the lingo just stuck.
