A: Cupertino, California, United States
By the end of 2013 Apple, which abandoned the word "computer" in its official name in early 2007, was only incidentally a personal computer manufacturer. In the third quarter of 2013 Mac revenue was $5.6 billion, or just 15% of the companies total revenue. At this point, Apple was primarily a smartphone company. In the same quarter, iPhone revenue topped $19.5 billion, accounting for 52% of the total for the three months.
