April 28th marks the tenth year since the launch of the iTunes Music Store, and to celebrate the anniversary, Apple launched an interactive timeline called A Decade of iTunes.
The timeline takes us on a walk down memory lane as it shows us significant milestones for iTunes from 2003 to 2013, whether it be a sales achievement, a new song or album that topped the charts, or the unveiling of a new Apple device.
You can find the timeline within iTunes itself, so go ahead and check it out yourself. You might learn a thing or two.
