Apple will sell its one billionth iPhone this summer and is likely to sell its 2 billionth by 2020, claims a new report.

Provided these numbers are accurate (and the first is almost certainly correct), it’s a timely reminder that — even during a period when the term “peak iPhone” is being thrown around — Apple’s astonishingly successful when it comes to selling its handsets.

Apple sold 896 million iPhones between 29 June, 2007 and the end of 2015. Half of all iPhone sales, moreover, have taken place in the past two years. According to Wall Street predictions, Apple is expected to report sales of 50 million iPhones during the first three months of 2016, which brings the total up to 946 million.

From there, it’s just a few months until Apple passes the “billion-selling” mark with the iPhone. Wall Street’s current estimates for the big day? July 20.

If you’re looking for even more impressive stats, Apple has sold more iPhones than it has sold Macs, iPads and iPods combined, dating back more than two decades to 1993.

If the iPhone business was spun off as its own business, meanwhile, the $155 million revenue it brought in last year would place it fifth on the list of Fortune 500 companies.

Apple’s no stranger to numbers in the billions. Back in November 2014, it sold its 1 billionth iOS device, including iPhones, iPads and the iPod touch. The App Store, meanwhile, saw its 50 billionth download back in 2013, while the 10 billionth iTunes song was downloaded in 2010.

Still, selling 1 billion of one particular product line (and particularly one many thought would never amount to a thing when it launched) is an extra special milestone to hit.
