The App Store is about to turn 10 years old, and so far, it's paid out some big bucks to software developers. The revenue for developers is $100 billion so far, said Apple CEO Tim Cook at the Apple World Wide Developer Conference Monday in San Jose.

Apple also has 20 million developers around the world, Cook said, adding that developers from 77 different countries were in the room at the event Monday. Both those numbers were records for Apple.
