"The iPhone is the most successful product of all time.
Over 1.6 billion have been sold. Including the iOS products it spun off, the total is over 2.2 billion. Of those 2.2 billion sold, 1.5 billion are still in use.
There are about 1 billion iPhone users.
Economically speaking, iPhone sales have reached one trillion dollars.1
Since the iPhone launched, Apple’s sales have totaled $1.918 trillion. Of those trillions about one half a trillion was accumulated in the form of income.
Of that half trillion in income, $360 billion was paid out to shareholders2. and $131 billion was paid in taxes." http://www.asymco.com/2019/05/16/the-pivot
