Neil Cybart:

A billion people now have iPhones. According to my estimate, Apple passed the billion iPhone users milestone last month. Thirteen years after going on sale, the iPhone remains the perennial most popular and best-selling smartphone.

Follow the headline link for some interesting analysis to back that number up. And not to be confused with the more than 2 billion iPhones sold over time (as of 2018).

This “billion iPhones” estimate is staggering, especially when you think back to where it all began, back in June 2007, when more than a few people saw the iPhone as a fad, thought Apple would be lucky to sell a million of them.

Apple sold 1.39 million in 2007, and 11.63 million in 2008. And, as it turns out, that was just a drop in the bucket.
