Visualized: The iPhone five years after launch  Mobile

In case you somehow missed it, today is an important milestone in technology nostalgia: it's the fifth anniversary of the original iPhone's launch. We'll let you explore the memories of that insane day on your own terms, but ComScore has produced a visual breakdown of just how ownership has grown and shifted over the years. It's not hard to see that adoption has been on an accelerating curve, especially after the 2010 launch of the Retina display-toting iPhone 4: as of this past May, about three quarters of owners have either the iPhone 4 or the iPhone 4S. And the 2007 edition? Only two percent of all iPhone owners are still actively holding on to the aluminum-clad debut model, which suggests most would rather have Siri than reminisce. Whether you're a fan or have since moved on to a competitor, the chart is a reminder of just how far one of Steve Jobs' biggest projects has come.
