It’s been exactly a decade since Apple launched an online store where its customers could download iPhone apps, with the iOS App Store debuting on July 10, 2008.

The store offered only about 800 apps for download initially, but Apple said in 2008 that the store still saw more than 10 million downloads the first weekend after it went live.
