Tim Cook enters the Steve Jobs Theater at Apple HQ, where the company announces its new products.

Apple's original headquarters, often referred to as "the mothership," was located in Cupertino, California, at the famous address 1 Infinite Loop. "Infinite Loop" is a reference to a computer program that will continue over and over again until forced to stop.

The campus consisted of six buildings — 1 through 6 Infinite Loop — ringed around an oval-shaped courtyard. While co-founder Steve Jobs reportedly was not a fan of the campus, he would often take his famous walking meetings in its courtyard.
