Prior to its construction, the land was occupied by the company Four-Phase Systems (later acquired by Motorola).

With the return of Steve Jobs to Apple in 1997, the campus became the company's official headquarters and its buildings were renamed "IL" instead of "R&D".

[4] The Apple Campus is located on the southeast corner of Interstate 280 and De Anza Boulevard, and occupies 32 acres (130,000 m2)[5] in six buildings spread over four floors.

The street, in conjunction with Mariani Avenue, actually does form a circuit (or cycle) that can circulate indefinitely.

Beyond Infinite Loop, the whole Apple Campus occupies an additional thirty buildings scattered throughout the city.
