Apple’s Worldwide Developers Conference kicked off today, and as usual, the keynote began with a bunch of Apple stats.

Before showing a video of the company’s latest retail store opening in Berlin, CEO Tim Cook revealed that a million people went to Apple’s retail stores per day last year. They now have 47 stores around the world in 14 countries. This particular store was opened in a hundred-year-old building.

On the digital side of things, Cook announced that people have downloaded 50 billion apps from the App Store. There are currently 900,000 apps in the store, and 93% of them, he said, are downloaded every month.

There are 375,000 apps specifically for the iPad, he noted.

There are 575 million store accounts.

Cook also announced that Apple has paid developers ten billion dollars, more than all of the other platforms combined, he said. The App Store, he said, “levels the playing field” between large and small developers.

The App Store will celebrate its 5th birthday next month.
