ABI Research has a new study showing the iPadApp Store has hit three billion downloads since it debuted in 2010.
The iPhone took as long as two years before being able to achieve this level of downloads, while the iPad made it within nearly a year and a half.
This represents roughly 19 percent of all iOS App Store downloads combined, which is a significant slice of the pie in terms of Apple's mobile ecosystem.
The New York Times has a great piece up on how app developers for the iPhone, iPad and iPod touch are in a mad rush to get their apps submitted and approved into the App Store before it goes dark for Apple's annual holiday break.
Apple's iTunes App Store has hit 10 billion downloads. Launched alongside iPhone 3G in 2008 it's grown to over 300,000 apps, with an install base of roughly 159 million iPhone, iPod touch and iPad devices sold to date.
