Apple on Wednesday started celebrating the 10-year anniversary of its iTunes store. When users head to the iTunes Store, they’ll find a new feature called “A Decade of iTunes.” The reason? Simple: on April 28, Apple will celebrate the 10th anniversary of the iTunes store. The feature allows users to browse a timeline of stories and the events that got iTunes to its place today. Things kick off with 2003 and the events that marked that year for iTunes. Users can then move their way through subsequent years and get glimpses of the way the store looked at different points in time. Apple also offered up some images of the products that were successful during those years. Apple has also shared the top-selling songs for each decade, making it easy for folks to download tracks that were popular in those years. One interesting note: Apple’s iTunes store launched on April 28, 2003 with only 200,000 songs available.
