Term: "Above the fold"

Refers originally to the top part of a newspaper, the term is used on the internet specifically to describe the top part of a landing page that is visible without having to scroll down. Also a great book by Brian Miller http://abovethefoldbook.com/ Marketing folk believe it is the best place for product placement or banner advertising. Above the fold differs slightly depending on the monitors settings, the higher the number the further the fold will be down the page.
