Apple today announced that developers have created over 100,000 apps for the revolutionary App Store, the largest applications store in the world. iPhone and iPod touch customers in 77 countries can choose from an incredible range of apps in 20 categories, including games, business, news, sports, health, reference and travel. App Store users have downloaded well over two billion apps, continuing to make it the world’s most popular applications store.

“The App Store, now with over 100,000 applications available, is clearly a major differentiator for millions of iPhone and iPod touch customers around the world,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “The iPhone SDK created the first great platform for mobile applications and our customers are loving all of the amazing apps our developers are creating.”

“The App Store has forever changed the mobile gaming industry and continues to improve,” said Travis Boatman, vice president of Worldwide Studios, EA Mobile. “With a global reach of over 50 million iPhone and iPod touch users, the App Store has allowed us to develop high quality EA games that have been a huge success with customers.”

“With 10,000 downloads a day, worldwide customer response to our I Am T-Pain App has exceeded our wildest expectations,” said Jeff Smith, CEO of Smule. “The App Store has given us a unique opportunity to create and grow a very successful business, and we’re looking forward to an exciting future.”

Apple continues to improve search and discovery with new features including Genius for Apps, App Store Essentials selections, sub category listings and more valuable customer reviews. With the recently introduced iTunes 9, it’s also now easier than ever to organize and sync your apps right in iTunes and they will automatically appear on your iPhone or iPod touch with the same layout.

The release of iPhone OS 3.0 this summer made over 100 new features available to iPhone and iPod touch users including Cut, Copy and Paste; MMS; landscape view for Mail, Text and Notes; stereo Bluetooth; shake to shuffle; parental controls; automatic login at Wi-Fi hot spots and Push Notifications. These new features have been incredibly popular with customers and there have already been more than two billion Push Notifications sent to apps available from the App Store. Additionally, the recently introduced In App Purchase feature for free apps means leading developers will now be able to offer customers the choice of buying content, subscriptions and digital services from directly inside their apps.
