Happy 10th Anniversary, App Store!

Today marks the 10th anniversary of the App Store for iOS devices, which launched on July 10, 2008, just a day before the iPhone 3G came out. The iPhone 3G was the device Apple used to debut the App Store, with the new functionality built into the iPhone 3G's operating system, iPhone OS 2.

Prior to the launch of the App Store, Apple in March of 2008 introduced an iPhone SDK, providing early app developers with the tools to build the first third-party apps. On stage at the announcement event, demo apps included EA's Spore Origins for the iPhone, AIM, Sega's Super Monkey Ball, and a Salesforce app, and within a matter of days, the original iPhone SDK had been downloaded more than 100,000 times.

When the App Store opened up in July 2008, 500 third-party apps were ready to download, and in less than a week, Apple announced 10 million apps had been downloaded. From Apple CEO Steve Jobs:

"The App Store is a grand slam, with a staggering 10 million applications downloaded in just three days. Developers have created some extraordinary applications, and the App Store can wirelessly deliver them to every iPhone and iPod touch user instantly."

Since that initial debut, the App Store has evolved on a yearly basis, with Apple continually refining and revamping the App Store experience for both consumers and developers. We thought we'd explore the App Store's history, highlighting the major evolutionary steps (and a few fun facts) that have ultimately transformed the way we use our iOS devices.

- September 3, 2008 - Apple rejects a "Pull My Finger" app for limited utility, giving us a first taste of the (sometimes confusing and conflicting) curation and moderation policies that have since governed the App Store. Other early app rejections were for reasons that included excessive data transfer, pornography/nudity, duplicating iPhone features, objectionable words (in a dictionary app), and fake reviews.

Apple last week published its own retrospective of the App Store, which is well worth reading as it explores thoughts from some of the most influential developers along with milestones that Apple feels are most important. In a statement, Apple's Phil Schiller said the App Store has exceeded the company's "wildest expectations."

"In its first decade, the App Store has surpassed all of our wildest expectations -- from the innovative apps that developers have dreamed up, to the way customers have made apps part of their daily lives -- and this is just the beginning. We could not be more proud of what developers have created and what the next 10 years have in store."

There's more in store for the App Store in the future, with some major changes in the works. In addition to the redesigned Mac App Store, Apple is developing common frameworks for iOS and Mac apps, with the eventual goal of making it easier for third-party developers to port iOS apps to the Mac.

As a first step, several iOS-only apps have been brought to the Mac, including Apple News, Stocks, Home, and Voice Memos. Starting in 2019, Apple plans to let developers begin porting iOS apps to the Mac using these frameworks, which will increase the availability of Mac apps.
