When Steve Jobs first introduced the iPhone back in 2007, the Apple co-founder laid out a rather modest goal for the company’s revolutionary smartphone — to sell 1 million units. At the time, 1 million in unit sales represented approximately 1% of the global smartphone market. And not only did Apple reach that goal with ease, it quickly became apparent that the iPhone itself was a juggernaut, a once-in-a-lifetime product that would forever change the way we interact with technology.
With each passing quarter, iPhone sales continued to skyrocket. Indeed, it wasn’t until the company’s March 2016 quarter that iPhone sales would experience their first year-over-year sales decline. That said, Apple last week reached an impressive new milestone — 1 billion iPhones sold.
